IMPORTANT WARNINGS

BEFORE INSTALLING OR HANDLING THE AP PLIANCE PLEASE CAREFULLY READ AND FOLLOW THE INSTRUCTIONS AND SAFETY STANDARDS DESCRIBED IN THIS MANUAL AND ILLUSTR ATED ON THE LABELS ATTACHED TO THE MACHINE.

This humidiﬁ er produces non-pressurised steam using heating elements immersed in the water contained in the cylinder (hereafter cylinder); the steam produced is used to humidify environments or industrial processes, through special distributors. The quality of the water used does not affect the evaporation process, and as a result the appliance can be supplied with untreated water, as long as such water is ﬁ t for drinking, demineralised or softened (see Supply water characteristics); the evaporated water is automatically replaced using a reﬁ ll valve. To achieve uniform distribution of the heat ﬂ ow, the heating elements, which are electrically insulated from the water, are covered in an aluminium casting, and are also available with a special non-stick coating to prevent and aid the removal of lime scale.

This appliance has been designed exclusively to directly humidify rooms or ducts, through distributors. It has been developed for this purpose, as long as: the installation, use and maintenance of the unit are carried out according to the instructions contained in this manual and on the labels applied, internally and externally, to the unit.

The environmental conditions and the voltage of the power supply must correspond to those speciﬁ ed. All other uses and modiﬁ cations made to the device that are not authorised by the manufacturer are considered incorrect. Liability for injury or damage caused by the incorrect use of the device lies exclusively with the user. Please note that the machine contains powered electrical devices and hot surfaces. All service and/or maintenance operations must be performed by specialist and qualiﬁ ed personnel who are aware of the necessary precautions. Disconnect the machine from the mains power supply before accessing any internal parts. The local safety standards in force must be applied in all cases.

2.1 Level control

Steam is produced with the heating elements completely immersed in water, whose level is controlled by a sensor made up of two independent and overlapping ﬂ oat switches, that is, the working level switch and safety level switch.

2.1.1 L evel control

It is composed of a ﬂ oat contained in a plastic pipe. Constrained to the level control case, an electronic board detect the ﬂ oat position and display the levels through three LEDs: green working level, yellow charge level, red safety level. The signals, working and safety level, are detailed in the paragraphs 2.1.2, 2.1.3.

2.1.2 Working level switch

This switch, which activates the ﬁ ll electrovalve, introduces water through the special pipe into the ﬁ ll tank, from where, dropping from a ﬁ ll diaphragm, it reﬁ lls the level inside the cylinder; the ﬁ ll electrovalve is ﬁ tted with a ﬂ ow limiter, maintaining the ﬂ ow basically constant on changes in mains pressure.

ENGLISH

2.1.3 Safety level switch

This switch shuts off power to the elements, activating the alarm in the case where the level is insufﬁ cient.

2.2 Overﬁ ll device

This is a device used to avoid water exiting the cylinder over the safety level, due for example to the malfunctioning of the control module (for more details, see THE HUMIDIFIER CONTROLLER) or to leaking from the ﬁ ll electrovalve. The ﬁ ll tank is ﬁ tted with an overﬁ ll diaphragm which diverts the excess inlet water, discharging it through special pipe. The overﬁ ll diaphragm is lower than the ﬁ ll diaphragm to avoid back ﬂ ow through the supply pipe.

2.3 Control of steam production

Steam production can be controlled either:

• By step, alternating steam production with standby using a humidistat or external contact; steam production can be controlled in four steps with pseudo-modulation from 30% to 100% of rated power, cyclically activating the remote-control switch (humidiﬁ er with type C control module).

• By continuous modulation from 0% to 100% of rated power, using solid-state relays (SSR); the control logic is PWM (pulse width modulation) with programmable base times (humidiﬁ er with type H or T control module).

2.4 Measurement of supply water conductivity- alarm

To optimise the functionality of the humidiﬁ er by suitably portioning the automatic draining cycles (see Automatic draining), when the ﬁ ll electrovalve is opened the conductivity of the inlet water is measured using the special electrodes in the tank. Two high conductivity thresholds can be set to activate respectively a pre-alarm and an alarm (with the shut-down of the appliance) when these thresholds are exceeded for at least 60 minutes, or instantly if the value measured is greater than three times the set value.

2.5 Automatic draining

The automatic draining function is managed by the control module. Part of the water contained in the cylinder is drained automatically, being replaced by fresh water to prevent an excessive salt concentration following the evaporation process. The drain pump/electrovalve is operated for a pre-set time at intervals that vary automatically as a function of the steam production and the content of solids dissolved in the supply water, detected using the conductivity measuring electrodes. Irrespective of the concentration of salt in the supply water, at least one drain cycle is performed within a maximum interval based on the quantity of steam produced; this is also true for demineralised supply water.

heaterSteam +030222011 - rel. 2.1 - 21.05.2010

Page 11

2.6 Foam elimination procedure

The level of water inside the cylinder is maintained by the level control at around 10-12 cm / 3.94-4- .72inch (about 18-20 cm /7.1-7.87inch for the cylinder of the 20-60 kg/h/44-132.2lbr/h humidiﬁ ers) from the top of the cylinder, therefore, when the high level electrodes are wet, an anomalous situation arises, generally caused by the presence of foam. In this case a drain procedure is activated, and is repeated until the phenomenon desists or, in the event of multiple activation, until the appliance is shut-down and an alarm state is signalled.

2.7 Safety thermostat (Motor Protector)

The mechanical safety thermostat with manual reset intervenes in the event of overheating, caused by a lack of water inside the cylinder due to the malfunctioning of the minimum level control. This deactivates the relay that controls the power supplied to the elements, and places the humidiﬁ er in an alarm state.

2.8 Autotest procedure

Each time the humidiﬁ er is started (switched from the OFF to the ON position), an autotest (default) procedure is performed, including checks on the operation of the level control, to test the regular functioning of the appliance:

1. “At” is shown during the autotest;

2. The autotest can be temporarily manually disabled by pressing key SEL during the initial 5 seconds after switching on heaterSteam: “-nt” will be shown. Note that this procedure disables the autotest only for the switch-on in course, not permanently (read below for disabling the autotest permanently);

3. The autotest can be disabled permanently by setting the parameter b1 as shown in table in chapter 11.4.

On start-up and on each draining cycle the operation of the level control is automatically checked by opening the ﬁ ll electrovalve until the activation of the working level switch (green LED) and, successively, opening the drain pump electrovalve until the activation of both level switches, and ﬁ nally, restoring the correct level, NOTE: returns to the working level only if there is demand, otherwise remains at the safety level; in the event of a failed test or irregular timing the remote-control switch is automatically deactivated and the alarm activated.

2.9 Measurement of the water temperature and pre-heating

(not available in the version with type C control module)

The control module measures, using an NTC sensor, the temperature of the water, and can be programmed to activate the pre-heating function near the value set for the start of humidiﬁ cation; in this way, steam production occurs more quickly.

ENGLISH

2.10 Dehumidiﬁ cation request signal (not available in the

version with type C control module)

If activated, this function closes the relay contact when the relative humidity measured by the transducer connected to the control module exceeds the set threshold. This signal can be used to activate an external dehumidiﬁ cation device.

2.11 Procedure for cleaning the drain valve (UR 2 to 10kg/h/4.4

to 22lbr/h)

For the models with drain valve there are two procedures used to clean the drain valve. The purpose is:

1. to prevent the valve from being blocked due to ﬂ akes of lime scale.

2. to prevent the solenoid drain valve from leaking.

• The ﬁ rst procedure is activated during a drain to dilute (automatic draining, see par. 2.5), drain due to

foam or due to inactivity cycle. This procedure is used to repeatedly activate and deactivate (with the ﬁ ll valve open) the drain valve for 1 second at start of the drain cycles.

• The second procedure, called “chattering”, is activated when ﬁ lling the water in steady operation, and

involves repeatedly activating and deactivating the drain valve for 1 second when the algorithm calculates that a no water alarm condition (“EF”) is about to occur.

3. CONTROL PRINCIPLES

The range of humidiﬁ ers includes the following control possibilities.

3.1 ON/OFF control (control module C)

The action in this case is all or nothing, activated by an external contact that determines the set point and the control differential (or hysteresis). Average steam production can be adjusted using a pseudo-modulating action, through the cyclical activation of the remote-control switch with a fractional actuation period (operation) that can be programmed in four steps: 30%, 50%, 75% or 100% of the total time (this mode can not be applied in severe operating conditions and without consequences on the noise level, caused by the frequent activation of the remote-control switch).

3.2 Modulating control (control module H)

The appliance is ﬁ tted with solid-state relays and steam production can be controlled continuously as a function of the required quantity, in one of the following modes.

As for the type C control module (see ON/OFF control (type C control module)).

3.2.2 Slave control, with signal emitted from an external regulator (parameter A0= 1)

Steam production is proportional to the value of an external signal Y, (selected by programming one of the following standards: 0 to 1Vdc; 0 to 10Vdc; 2 to 10Vdc; 0 to 20mA; 4 to 20mA) the entire range of which is indicated by BP (proportional band). The maximum production Pmax, corresponding to the maximum value of the external signal Y, can be programmed between 10% and 100% of the rated value of the humidiﬁ er. The minimum production Pmin is ﬁ xed at 10% of the rated value, with an activation hysteresis provided by the value hy, equal to 2% of the entire range BP of the external signal Y. If enabled, the pre-heating function overlaps the control diagram, and is activated when the external signal Y is lower than the activation point for steam production by a quantity b2.

3.2.3 Autonomous control with relative humidity transducer (parameter A0= 2)

Steam production is linked to the measurement of % rH, performed by the relative humidity transducer connected to the regulator, and increases as the distance from the set point St increases.

The maximum production P0, which occurs when the relative humidity is less that the set point by a value P1, can be programmed between 10% and 100% of the rated value of the humidiﬁ er. The minimum production Pmin is ﬁ xed at 10% of the rated value, with an activation hysteresis provided by the value hy, equal to 10% of P1. The pre-heating function, if enabled, overlaps the control diagram and is activated when the relative humidity % rH, measured by the transducer, is higher than St by a programmable quantity b2. The dehumidiﬁ cation function, if enabled, overlaps the control diagram and is activated when the relative humidity % rH, transmitted by the transducer, is higher than St by a programmable quantity P5+P6; the hysteresis of the step, also programmable, is equal to P6.

To check that the relative humidity measured by the transducer is within the pre-set values, the control

module with autonomous control allows two alarm thresholds to be programmed:

• high relative humidity alarm threshold P2;

• low relative humidity alarm threshold P3. When these thresholds are exceeded, after a programmable delay P4, an alarm state is activated, with

With autonomous control (parameter A0=2) it is also possible to have an ON/OFF action, as represented in the graph, by disabling power modulation (setting parameter b0=0). The pre-heating and/or dehumidiﬁ cation, if enabled, remain unchanged.

3.2.4 Autonomous control with ambient relative humidity transducer and outlet humidity

limiting transducer (parameter A0= 3)

In this case too the regulator modulates steam production as a function of the measurement % rH performed by the main relative humidity transducer, however, in addition, its entity is limited if the relative humidity % rH2 measured by a second compensation transducer placed in the air duct downstream from the humidiﬁ er exceeds the maximum desired value. To prevent the relative humidity measured by the transducer in the air duct downstream from the humidiﬁ er exceeding a value considered as excessive, the control module with autonomous control and second transducer connected allows a high outlet relative humidity alarm threshold P9, to be programmed. If this threshold is exceeded, after a programmable delay P4, an alarm state is activated, with closing of the contact of the corresponding relay on the main control board.

3.2.5 Application for steam baths (type T control module)

In applications for steam baths, where the control probe measures temperature rather than humidity, the same considerations are valid as for the type H control module with modulating action and autonomous control. Recommended transducer: SSTOOB/P40, ASET030001 or ASET030000.

3.3 Setting the alarm thresholds (type H or T control module)

The control module panel allows the setting of limit thresholds for the activation of the alarm in the event where these are exceeded. These alarm thresholds can be programmed using the following control parameters:

• P2: high relative humidity alarm threshold, measured by the room probe;

• P3: low relative humidity alarm threshold, measured by the room probe;

• P4: alarm signalling delay (to prevent false signals);

• P9: high relative humidity alarm threshold, measured by the outlet probe (for ducted humidiﬁ cation).

Parameters P2, P3, P4 are programmable only when A0=2 or 3; parameter P9 is programmable only when A0=3. Furthermore, the control module can signal the excessive conductivity (and salt concentration) of the supply water, but only as a default setting.

WARNING: the parameter A0 and the operating and alarm parameters Px and b0 are set in the factory (default values valid for normal applications). Nonetheless, these can be modiﬁ ed by the user, following the instructions contained in: Reading and programming the parameters for the type H or T control module.

5. POSITIONING THE UNIT

The humidiﬁ er must be positioned and fastened by qualiﬁ ed personnel, following the instructions listed herein.

Choose the best location for the installation of the steam distributor, that is the position which minimises the length of the steam pipe or, in the case of direct ambient humidiﬁ cation using a ventilated distributor, the central point of the space being humidiﬁ ed (see STEAM DISTRIBUTION). The unit is designed to be mounted to a wall that must be able to support its weight in operating conditions (see Dimensions and weights). The metal casing of the humidiﬁ er heats up during operation, and the rear part resting against the wall may reach temperatures above 60 °C / 140 °fH; ensure that this does not cause any problems. Make sure the machine is level, respecting the minimum distances indicated in the drawing, to allow the necessary maintenance operations.

WARNING: ensure that the cooling fan outlet grille is not blocked or covered.

5.1 Fastening

The appliance must be fastened to the wall using the supplied screws and plugs. Use the following distances for the drilling template.

6. WATER CONNECTIONS

The water connections for the supply and the draining of the unit must be made by specialist and qualiﬁ ed personnel, who are capable of performing the work correctly and according to local standards. Before making the connections, ensure that the machine is disconnected from the mains power.

6.1 Supply water characteristics

The supply water for the electric heater humidiﬁ er must not be corrosive, must not emit bad odours, and must not contain too much lime to avoid excessive deposits. The water, supplied from mains drinking water or demineralised water, must have the following characteristics:

Note that treating the water with softeners or polyphosphates does not decrease the quantity of dissolved salts, and can lead to the formation of foam and hence irregular operation and corrosion of heating elements. If softened water is used, it should be diluted with mains tap water in such proportions as to ensure a minimum hardness of 5° fH, and parameter b4 should be set (value 1500) so as to increase the frequency of the drain cycles for dilution.

Not recommended:

1. the use of well water, industrial water or water from cooling circuits and, in general, water which may be chemically or bacteriologically contaminated;

2. the addition to the water of disinfectants or anticorrosion compounds, as these may cause irritation.

Nota: no relationship can be proven between water hardness and conductivity; nonetheless, as an indication only, water with a hardness of 40°fH should have an approximate conductivity of around 900-1000 mS/cm at 20 °C/68°fH.

6.2 Characteristics of the drain water

Inside the humidiﬁ er water boils and steam is produced, without the addition of any kind of substance. The drain water, therefore, contains the same substances as those dissolved in the supply water, yet in a greater proportion, depending on the concentration in the supply water and the set drain cycles; it can also reach a temperature of 100 °C collection system. The drain pipe, as well as being resistant to high temperatures, must also guarantee the correct downﬂ ow of the water; a downward slope of at least 5° is therefore recommended.

6.3 Technical speciﬁ cations

UR 2-10 kg/h

The installation of the humidiﬁ er requires connection to the supply water and drain pipe.

The connection of the supply water can be made using rigid or ﬂ exible pipes with a minimum recommended internal diameter of 6mm, ﬁ tted with a shut-off tap to allow the appliance to be disconnected

during maintenance operations. To simplify installation it is recommended to use CAREL ﬂ exible pipes with an internal diameter of 6 mm and an external diameter of 8mm (code 1312350APN) and the rotating 3/4”G straight (code 9995727ACA) or elbow connector (code 9995728ACA), available upon

request. It is recommended to install a mechanical ﬁ lter to trap any solid impurities.

The drain water connection is made using a section of rubber or plastic pipe resistant to temperatures of 100°C/212°fH, with a recommended internal diameter of 36 mm/1.42inch (see table 6.3.1). This section of pipe must be fastened using metal clamps:

UR 20-27-40-60 kg/h

• above, onto the appliance outlet pipe coupling;

• below, onto the rigid pipe, with a minimum slope of 5°. In the humidiﬁ ers UR 020-027-040-060 the drain tank must be emptied connecting a rubber pipe, which has to be connected to the discharge system, withstanding 100 °C/212°fH with øint.= 20 mm /0.79inch and fastened with a metallic band.

IMPORTANT WARNING: the drain pipe must be free, without back-pressure and with a drain trap immediately downstream from the connection to the humidiﬁ er. We suggest you use a safety device (not supplied) that, in case of breaking of the hydraulic connections outside the humidiﬁ er, prevents possible ﬂ ooding.

6.4 Checks

The following conditions represent correct water connections:

• disconnection of the supply water line using a shut-off tap;

• presence of a mechanical ﬁ lter in the supply water line;

• water temperature and pressure within the acceptable values;

• drain pipe resistant to temperatures of 100°C/212°fH;

• minimum drain pipe internal diameter of 40mm/

• minimum slope of drain pipe greater than or equal to 5°.

IMPORTANT WARNING: on completion of the installation procedure, ﬂ ush the supply pipe for around 30 minutes by passing water directly through the pipe and without introducing it into the humidiﬁ er. This will allow the elimination of any scoria and processing residues that may cause the formation of foam during the boiling process.

7. ELECTRICAL CONNECTIONS

The electrical connections must be made by specialist and qualiﬁ ed personnel, who are capable of performing the work correctly and according to local standards. Before making the connections, ensure that the machine is disconnected from the mains power.

Check that the voltage of the appliance’s power supply corresponds to the value indicated on the data plate inside the electrical panel. Introduce the power and ground connection cable gland into the electrical panel through the fairlead supplied, connect the ends to the terminals and fasten them in place using the special tear-proof cable gland clamp (see Fig. 2.1). The power line to the humidiﬁ er must be ﬁ tted with a cut-off switch and fuses protecting against short-circuits, to be mounted by the installer. Table 7.1.1 sh ows the recommended cross-sections of the power cable and the recommended sizes of the fuses; note, however, that this data is purely indicative and, in the event of non-conformity with local standards, the latter must prevail.

Before making the auxiliary connections, disconnect electrical power to the appliance!

7.4.1 Type C control module with ON/OFF action

The humidiﬁ er is controlled by a mechanical humidistat H or a voltage-free remote contact CR, or a combination of both. The control module can be connected to an RS485 serial line, or alternatively to the CAREL Humivisor remote control panel, marked as MT, or to a remote supervisor. The diagrams in Fig. 7.b and 7.c show the connections to be made on the terminal block I, in the following cases: a. action commanded by simple enabling contact; b. action from external mechanical humidistat; c. combination of the above.

7.4.2 Type H control module with modulating action

The humidiﬁ er with modulating action is ﬁ tted with solid-state relays, and its capacity can be varied from zero to 100% depending on the control requirements. In this case too, the humidiﬁ er can be connected via RS485 to the CAREL Humivisor MT remote control panel or a remote supervisor. It can be

humivisor

controlled in the following three different modes.

a) Slave control, with signal from an external regulator.

Steam production is managed by an external regulator R (Fig. 7.d) that transmits a modulating signal to the control module; the control module can be programmed to receive alternatively one of the following modulating signals (see THE HUMIDIFIER CONTROLLER):

• voltage signal: 0 to 1Vdc; 0 to 10Vdc; 2 to 10Vdc;

• current signal: 0 to 20mA; 4 to 20mA.

The reference (zero) of the external regulator must be connected to terminal 6I on terminal block I and the control signal to terminal 5I (Fig. 5.e). To avoid disturbances in control, the ground of the external regulator must be connected to the ground of the control.

7.5 Other auxiliary contacts

7.5.1 Alarm contact

The humidiﬁ er’s control module features a voltage-free switching contact for the remote signalling of the presence of one or more anomalous events or alarms. Connection to the alarm contact (250 Vac; maximum load: 8 A resistive - 2 A inductive) is made using the removable terminal block H, as per Fig. 7.l.

7.5.2 Dehumidiﬁ cation contact

In the advanced version with internal control and humidity transducer, the control module features a voltage-free NO contact, the closing of which can, if required, be programmed to activate an external dehumidiﬁ cation device: in this case the appliance assumes the functions of a complete ambient relative humidity control. Connection to the dehumidiﬁ cation contact (250 Vac; maximum load: 8 A resistive - 2 A inductive) is made using the removable terminal block G, as per Fig. 7.m.

Fig. 7.l

Fig. 7.m

7.5.3 Remote terminal/supervisory system

The humidiﬁ er’s control module can be connected to an RS485 serial line, as per the diagram in Fig. 7.n, or alternatively to:

• a CAREL Humivisor remote control panel (see speciﬁ c instruction manual), which can be connected to four different humidiﬁ ers;

• a remote supervisory system.

The transmission line can reach a maximum distance of 1000 metres between the two most distant points.

7.5.4 Using different brand probes

Different brand probes can be used, with output signals selected, by programming the parameter A2, (see THE HUMIDIFIER CONTROLLER) from the following:

• voltage signal: 0 to 1 Vdc; 0 to 10 Vdc; 2 to 10 Vdc;

• current signal: 0 to 20 mA; 4 to 20 mA.

In addition, the maximum and minimum values must be programmed for the signal (parameters A3 and A4 for the room probe; A7 and A8 for the outlet probe).

The probes can be powered at the following voltages:

• 12 V stabilised at terminal 4I;

• 32 Vdc from the rectifying of 24 Vac at terminal 3I.

The control signals must be connected:

• for the control probe HT (TT in the case of controls for steam baths) to terminal 5I, whose reference ground (GND) is terminal 6I;

• for the limiting probe CH, to terminal 1I, whose reference ground (GND) is terminal 2I.

IMPORTANT WARNINGS:

• To avoid disturbances to control, the ground of the probes or the external regulators must be electrically connected to the ground of the appliance’s control;

• For humidiﬁ er operation terminals 7I and 8I must be connected by an enabling contact or a jumper (default solution). If terminals 7I and 8I are not connected, all internal and external devices com manded by the control are disabled.

8. STEAM DISTRIBUTION

For optimal performance of the humidiﬁ er, the steam produced must be introduced into the room/duct in a uniform way, without projecting droplets and without noticeable condensation, using ventilated steam distributors or linear distributors. The steam distributor must be chosen according to the place where the steam is introduced. If the steam is to be distributed directly into the environment (rooms, warehouses, etc.), the ventilated steam distributors used (optional) should be ﬁ tted with a motorised fan. If, on the other hand, the steam is to be introduced into a duct or air handling system, linear distributors must be used, which exploit the speed of the air itself for distribution.

8.1 Ambient steam distribution: ventilated steam distributors

Ventilated steam distributors, used to distribute steam directly into the environment, can be mounted onto the humidiﬁ er (see Fig. 8.a) or positioned separately and connected to the humidiﬁ er (see Fig. 8.b) using steam pipes. The drawings show the minimum recommended distances to prevent the ﬂ ow of humidiﬁ ed air from coming into direct contact with persons, lights, electrical appliances, false ceilings and cold surfaces before the steam is completely absorbed by the environment.

For further details on the mounting and use of ventilated steam distributors, please refer to the speciﬁ c instruction manual.

8.2 Steam distribution in cold rooms

It is possible to humidify a cold room using a ventilated steam distributor, ensuring that this works within the limits of its operating range. The cold room must have an operating temperature between

-10 °C (14°fH) and +40 °C (104°fH), with a relative humidity of not over 80% rH. If these limits are not

possible, the steam can be distributed in the cold room using a linear distributor. In any case, the steam must not come into direct contact with cold air streams from the cold room’s refrigeration unit, to avoid possible re-condensation.

8.3 Ducted steam distribution: linear and concentrated jet distributors (OEM)

For steam distribution in air ducts, the steam distributor must be suitably proportioned to the power of the humidiﬁ er and the cross-section of the ducts. For this purpose, CAREL supplies two ranges of linear distributors: one of stainless steel, with plastic ends. Figures 8.c and 8.d provide the dimensions of CAREL distributors. Table 8.a indicates the minimum number and model of the distributors recommended for the type of humidiﬁ er used.

The linear distributors are mounted (see Fig. 8.d):

• by making a series of holes in the wall of the duct, as per the drilling template indicated in Figs.: 8.a or 8.b;

• inserting the distributor with the steam outlet holes facing upwards;

• fastening the ﬂ ange of the distributor using 3 screws.

To allow the condensate to return through the drain connection (see Installing the condensate return pipe), mount the distributor at a slight angle (at least 2°-3° Fig. 8.c) with the inlet connection nearer than the closed end, which, for this reason, must be adequately supported.

8.4 Concentrated jet steam distribution (OEM) (only for humidiﬁ ers up to 10 Kg/h/22 lbr/h)

For special applications (e.g. steam baths, technological machinery) a plastic OEM concentrated jet distributor is available, with holes (12 or 22 mm)/(0.47 or 0.87 inch) or without, allowing the user to make these according to requirements (see Fig. 8.e). The OEM distributors can be ﬁ tted, horizontally or vertically with the hole facing upwards, onto a support with the same holes as per the drilling template for the aluminium linear distributor (see Fig. 8.e).

N.B.: when using steam tubing with an internal diamter of 30 mm/ 1.18 inch, remove the 22 mm/ 0.87 inch steam inlet section.

8.5 Positioning linear distributors in the air duct

Depending on the dimensions of the air duct, the distributors must be as long as possible and placed away from curves, branches, changes in cross-section, grilles, ﬁ lters, fans. The minimum recommended distance between the steam distributor and the nearest obstacle is around 1 to 1.5 metres/3.28 to 4.92 feet, yet this strongly depends on the operating conditions; it in fact increases as a result of:

• the increase in speed of the air in the duct;

• the increase in relative humidity of the air before and, above all, after humidiﬁ cation;

• the decrease in turbulence. The distance can be shortened using a series of distributors in parallel. Refer to the layout and the distances between the distributor and the walls of the duct and/or between two distributors as shown in the following drawings.

8.6 Installation of the steam pipe

The connection between the humidiﬁ er and distributor must be made using a suitable pipe, such as the CAREL ﬂ exible pipes. The use of incorrect pipe may lead to fragility and cracks and consequent steam leaks.

The shape of the pipe must be such as to avoid the accumulation of condensate and consequent noise (in the form of gurgling) and loss of efﬁ ciency; the course of the pipe must exploit gravity to drain the re-condensed steam back to the cylinder or the distributor. Avoid the formation of pockets or traps where condensate may form; furthermore, ensure that the pipe is not choked due to tight bends or twisting (see Fig. 8.g).

Fasten the ends of the pipe to the connections on the humidiﬁ er and the steam distributor using screw clamps, so that they do not come loose as a result of the temperature.

Depending on the position of the steam distributor, the course of the pipe may be one of the following:

1. upwards with a vertical section at least 300mm/11.8 inch in length, followed by a bend with a minimum radius of 300 mm/11.8 inch, and ﬁ nally a downward section with a constant slope of not less than 5° (see Fig. 8.h);

2. for very short courses (less than 2 metres/7 feet), a curve with a minimum radius of 300mm/

11.8 inch followed by from an upward section with a slope of not less than 20° (see Fig. 8.i).

D>200mm

IMPORTANT WARNING: the length of the steam pipe should be less than 4 m/13.1 feet.

R>300mm

8.7 Installing the condensate return pipe

Due to the re-condensation of part of the steam produced, condensate forms in the steam conveyance pipe and inside the distributor, which must be drained to avoid gurgling, and loss of efﬁ ciency. The condensate is drained by the effect of gravity with the help of a ﬂ exible pipe suitable for this purpose. The use of an incorrect pipe can lead to fragility and cracks and consequent water leaks. To avoid the non-condensed steam from being released through the condensate pipe, a trap must be created by curling a part of the drain pipe. The end of the condensate pipe can be connected to the nearest drain, with a minimum slope of 5° to assist downﬂ ow (see Fig. 8.h). If there is enough distance from the distributor, the hose can be introduced into the humidiﬁ er through the hole on the top of the unit, reaching the boiler supply tank (for 20-60kg/h units), or alternatively connected to the special C ﬁ tting supplied, to be tightened to the top of the humidiﬁ er, so as to drain the condensate from boiler supply tank (see Fig.. 8.i).

IMPORTANT WARNING: for correct functioning, the drain trap must be ﬁ lled with water before starting the humidiﬁ er.

8.8 Checks

The following conditions represent the correct installation of the steam pipe:

• the position of the steam distributor conforms to that described in this chapter, the steam outlet pipe points upwards and the distributor is inclined at least 2° upwards;

• the ends of the pipes are fastened with metal screw clamps;

• the curves in the pipe are quite wide (radius > 300 mm /11.8 inch) so as not to cause pinching or choking;

• there are no pockets or traps in the steam pipe to avoid condensation;

• the courses of the steam pipe and the condensate pipe conform to those described in this chapter;

• the length of the steam pipe does not exceed 4 metres/13.1 feet;

• the slope of the steam pipe is sufﬁ cient to drag the condensate (> 20° for the upward sections, > 5° for the downward sections);

• the slope of the condensate pipe is at least 5° at each point;

• the condensate pipe features a drain trap (ﬁ lled with water before start-up) to avoid the release of steam.

heaterSteam +030222011 - rel. 2.1 - 21.05.2010

Page 41

9. START-UP

IMPORTANT WARNING: on completion of the installation procedure, drain the supply pipe for around 30 minutes by passing water directly through the pipe and without introducing it into the humidiﬁ er. This will allow the elimination of any scoria and processing residues that may cause the formation of foam during the boiling.

9.1 Preliminary checks

Before starting the humidiﬁ er, check that:

• the water and electrical connections are made and the steam distribution system is conﬁ gured according to the instructions contained herein;

• the shut-off tap for water into the humidiﬁ er is open;

• the power fuses are installed and in tact;

• terminals 7I and 8I are connected by jumper or connected to the remote ON/OFF contact, and that the latter is closed;

• the probes or the external control device are correctly connected (and that the ground of these devices is electrically connected to the ground of the main control board);

• the steam outlet pipe is not choked;

• in the event of ducted humidiﬁ cation, the operation of the humidiﬁ er is slave to the operation of the air fan (replacing or in series with the remote ON/OFF contact);

• the distributor condensate return pipe is installed and free;

• the drain pipe is correctly connected and free.

Before starting the humidiﬁ er, check that it is in perfect condition, that there are no water leaks and that the electrical parts are dry. Do not supply voltage if the humidiﬁ er is damaged or even partially wet!

9.2 Removing the heating element centring spring (only for

three-phase models)

To prevent the elements in three-phase models hitting each other or against the internal wall of the cylinder and thus damaging the appliance, due to vibrations or bumps during transport, the heating elements are factory-ﬁ tted with a centring spring, which has no function during the operation of the appliance.

As the centring spring may hinder the removal of lime-scale from the elements and diminish the interval between cleaning cycles, the spring should be removed before the initial start-up. To do this, remove the cylinder by following the relative instructions (see Maintenance of the cylindercylinder).

9.3 Start-up

After having closed the power switch to the humidiﬁ er, turn the appliance on by moving the rocker switch (next to the DRAIN button) located in the bottom right of the frame, to the I position. The start-up sequence is then initiated. This includes the initial phase, the autotest phase, and ﬁ nally, the actual operating phase. According to the model of the humidiﬁ er’s control module, the start-up sequence is signalled by the lighting up of the LEDs on the control panel, as described in the following chapter.

10. THE HUMIDIFIER CONTROLLER

Two types of electronic controller are available for the electric heater humidiﬁ er (see CONTROL PRINCIPLES):

• Type C control module, with indication LEDs and ON/OFF action This control provides control of the steam production capacity and ON/OFF control;

• Type H or T control module, with numeric LED display and modulating action This control provides complete control of the steam production capacity, with optional dehumidiﬁ cation function; it accepts signals from humidity probes or from external electronic devices with proportional (or ON/OFF) control).

10.1.4 Alarm indications

The lighting up of LED 9 (see Fig. 10.a) and a combination of the LEDs 5 indicates the presence of a current alarm state; in the event of more than one alarms, the LEDs 5 light up in sequence, at 2 second intervals. At the same time, the control module activates the alarm relay (see ELECTRICAL CONNECTIONS). To interpret the type of alarm, see ALARMS AND TROUBLESHOOTING. The control module continues to indicate the alarm state (even if this is no longer active) until the reset button is pressed; still active alarms can not be reset.

10.1.5 Manual drain command

In the ﬁ rst 5 seconds from the start-up of the unit (during the autotest sequence: see Fig. 10.c), press the  and  buttons at the same time. After 2 seconds the drain solenoid valve is activated and completely empties the water contained in the cylinder. To stop the drain cycle, press the  and buttons again.

10.1.6 Setting the steam production

The average steam production can be adjusted using a pseudo-modulating action, with the cyclical activation of the remote-control switch and a programmable operating interval divided into four steps: 30%; 50%; 75%; 100% of the total time (this mode can not be applied in severe operating conditions and without consequences on the noise level caused by the frequent activation of the remote-control switch). To do this, use the  and buttons, see Fig. 10.a.

11. READING AND PROGRAMMING THE PARAMETERS OF THE TYPE H OR T CONTROL MODULE

The numerical, conﬁ guration and control panel parameters are grouped into three levels:

1. LEVEL 1 - set point, that is the value of the appliance’s main setting St, accessible directly via the keypad for both reading and modiﬁ cation;

2. LEVEL 2 - control parameters and measurements, that is the physical vales measured and the functional parameters involving the control of the humidiﬁ cation process; these too can be accessed directly via the keypad for reading and modiﬁ cation;

3. LEVEL 3 - conﬁ guration parameters consisting of the data needed to customise the control, according to the requirements of the humidiﬁ er. These parameters are can be accessed only by password, to prevent the unwanted modiﬁ cation of the conﬁ guration and the humidiﬁ er’s essential functions.

Each parameter is composed as follows:

code alphanumeric symbol appearing on the display corresponding to the parame-

range of variation limit values within which the parameter can be modiﬁ ed default value set in the factory for the parameter unit of measure symbol displayed showing the unit of measure used for the parameter

Warning: the numerical values from 200 to 255 are displayed with the symbol / in the place of the hundreds digit 2 (due to the speciﬁ c constructive conﬁ guration of the display). Figure 11.a shows how the number 215 is displayed.

11.1 Reading and programming the set point

To read and/or change the set point, proceed as follows:

• press the SEL button for around 2 seconds, until St appears;

• on releasing the button, the unit of measure of the set point is displayed for 1 second, and ﬁ nally the

current set value;

• to change the set point, press the  and  buttons, checking that the action is being performed on

the display;

• press the SEL or PRG button to conﬁ rm the value displayed and conclude the programming of the set

point.

11.4 Validity of the modiﬁ cations to the parameters

The modiﬁ cations made to the parameters normally take effect when conﬁ rmed with the SEL button, and are saved permanently with the PRG button. For some parameters relating to the serial connection, the value will only take effect only the next time the unit is switched on. During the programming phase, 5 seconds after the last button is released, the display begins ﬂ ashing (to remind the user that he is in programming phase). Sixty seconds after the last button is released, if the value of a parameter is being displayed, any modiﬁ cations are ignored and the display returns to the parameter’s identifying code. After a further 5 seconds, the display begins ﬂ ashing again, and after 60 seconds the programming phase is terminated and the parameters return to the values previous to the programming phase. If, on the other hand, the parameter’s identifying code is being displayed, the programming phase is terminated directly after 60 seconds (time out).

11.5 Recalling the default parameters (factory settings)

The default values can be recalled only on start-up, and in the following way:

• in the ﬁ rst 5 seconds from start-up (while the three dashes are displayed), press the PRG button until the upper dash in the centre ﬂ ashes, as indicated in the Figure;

• release the PRG button within 3 seconds to conﬁ rm the recall and permanent saving of the default parameters; to conﬁ rm the saving of the values, the upper dash will stay on for 2 seconds (as displayed in Fig. 11.n);

• the operation is not effected if the PRG button is pressed for more than 3 seconds, until the upper dash disappears.

SEL

Recalling the default parameters does not change the parameter relating to the unit of measure (A1), it is thus recommended to check and if necessary select and save the unit of measure as required,

and then recall the default parameters. In this way the default values will automatically be converted.

11.6 Resetting the hour counter

To reset the hour counter (parameter d4), proceed as follows:

• press the PRG button for 5 seconds, until the code P0 is displayed, indicating the ﬁ rst modiﬁ able parameter; using the  and  buttons, scroll the parameters until d4 is displayed;

• press the SEL button to display the value of the hour counter (preceded for 1 second by the unit of measure);

• press the  and  buttons together for 5 seconds until the value is set to zero, preceded by a brief ﬂ ash.

11.7 Displaying and modifying the unit of measure

The unit of measure of some parameters depends on the type of control and the programming. Displaying the unit of measure can then avoid incorrect interpretation. In the case of non-dimensional measurements, the unit of measure is not displayed. It is also possible to use imperial rather than standard units of measure (parameter A1). For the procedure to be followed please refer to: Programming: accessing type A, b and C parameters. The two digits on the right are used to display the unit of measure:

11.8 Automatic total drain for inactivity

For hygienic reasons it is recommendable to empty the boiler not to have stagnant water inside in case there isn’t any humidiﬁ cation request for a long time. In UR*H* and UR*T* the user can set the automatic total drain for inactivity as follows (read the remarks below for UR*C*):

• The drain for inactivity is active by default. To disable it, simply go to parameter “b1” and operate as described in the table in chapter 11.4;

• Vice-versa, if the drain for inactivity has been disabled, to enable it go to parameter “b1” and operate as described in the table in chapter 11.4 and ﬁ x the maximum inactivity period through the parameter bC.

The automatic total drain for inactivity is enabled by default and the max. allowable default inactivity period is 3 days, which means that the boiler is emptied automatically after heaterSteam has been on for at least 3 days without humidiﬁ cation request.

Parameter bC:

Range 1 to 199 days Default 3 days Step 1 day Remarks heaterSteam must be left on in order to empty the boiler;

UR*H* and UR*T*: the display shows “idr” during the automatic total drain for

inactivity;

UR*C*: the automatic total drain for inactivity is enabled by default and the

boiler is emptied after 2 days of inactivity (ﬁ xed default) but neither b1 nor bC can be edited.

11.9 User-adjustable duration of dilution drain

The duration of the dilution drain can be adjusted through the new user parameter bD which deﬁ nes the new duration as a % of the internally set default duration: new duration= default duration x bD / 100.

Example: if the internally set duration 10 s and bD= 50%, then the new duration= 10 s x 50 / 100= 5 s.

Parameter bD:

Range

Default Step Remarks

0 to 190 % (0 % disables the dilution drains. WARNING: READ REMARKS BELOW!) 100 %; 10 %. bD= 0 % means that dilution drains are NOT DONE at all. WARNING: RISK OF FOAM/CORROSION as the internal conductivity will increase. We recommend to set bD= 0 after a very careful evaluation of the water quality and consequences. bD= 100 % means that the default duration will be used bD< 100 % means that the duration is < default duration: less fresh water is introduced after the drain thus reducing its negative impact on the steam production (good for high precision applications), but the drain valve will open more frequently in order to control the internal conductivity (decreasing lifetime). WARNING: RISK OF FOAM IN CASE bD IS TOO SMALL IN RELATION THE WATER QUALITY bD> 100 % means that the duration is > default duration: to be used for diluting strongly the internal water when facing big foam and/or corrosion problems. Steam ﬂ ow will be negatively affected because of the larger amount of fresh water introduced after the drain; Choice of bD for a high-precision control of %rH: bD should be decreased as much as possible, yet avoiding foam/corrosion. Choice procedure: trialand-error on ﬁ eld

11.10 User-adjustable max. allowed no. of evaporation cycles

between 2 dilution drains

The no. of evaporation cycles between 2 subsequent dilution drains is internally calculated, but, through the new parameter b8, the user is allowed to specify the max. allowed no. of evaporation cycles between 2 dilution drains. This means that the next diluition drain is done before the end of the b8 evaporation cycle following the last diluition drain and NOT AFTER the b8-th evaporation cycle.

Parameter b8:

11.11 Reduced ﬁ lls to restore water level after evaporation

When, during the steam production, the upper ﬂ oater switches because the water level has decreased, a ﬁ ll starts for restoring the water level. The duration of the ﬁ ll can be decreased through the new user parameter bA which deﬁ nes the new duration as a % of the internally set default duration: new duration= default duration x bA / 100. Note that, regardless the value entered into bA, the water level will be always restored up to the upper ﬂ oater.

Parameter bA:

Range 20 to 100 % Default 100 % Step 10 % Remarks

bA= 100 % means that the default duration will be used bA< 100 % means that the duration is < default duration: a smaller amount

of fresh water is introduced into the cylinder, thus with a smaller impact on the steam production (good for high precision applications); on the other side, however, the ﬁ ll valve will open more frequently

11.12 PW M ﬁ lls after dilution and high-level/foam drains

After a dilution or high-level/foam drain, water is ﬁ lled into to restore the water level up to the upper ﬂ oater. The ﬁ lled fresh water disturbs the steam production because it decreases the average temperature of the water inside the boiler: in order to reduce the negative inﬂ uence of the fresh water on the steam production, the user can enable the PWM ﬁ lls after the dilution and high-level/foam drain. PWM ﬁ lls work as follows:

1. the mass of fresh water required to restore the water level is divided into smaller masses of fresh water;

2. by keeping the partial ﬁ lls as farther apart as possible from each other, each partial mass of fresh water is given the maximum possible time for heating up before the next one arrives, thus reducing the effect of the fresh water on the steam production.

The duration of each ﬁ ll can be deﬁ ned in seconds by the new user parameter bE:

Range 5 to 199 seconds Default seconds, which corresponds to one single ﬁ ll, i.e. no PWM ﬁ lls, because a 199s ﬁ ll

Step 1 second

is long enough to restore alone the water level

12. THE REMOTE CONTROL (OPTIONAL ACCESSORY)

The remote control is an optional accessory and can only be used on humidiﬁ ers with type H or T control module (modulating). It is available in two versions:

z. neutra deum.

differenz. deum.

Fig. 12.a

• TELURI000 with buttons marked in Italian;

• TELURE000 with buttons marked in English. The infra-red remote control can command the call-up and display on the control module (see THE HUMIDIFIER CONTROLLER) of the humidiﬁ er’s parameters, which, if necessary, can be modiﬁ ed remotely. Furthermore, the remote control simpliﬁ es access to the main parameters, by pressing the corresponding marked buttons, avoiding the code search phase. The remote control will operate at up to a distance of 3 metres, and can be used with all appliances in the heaterSteam family. In the event where there is more than one humidiﬁ er within the remote control’s operating range, the appliance to be operated can be determined by assigning each control module an individual access code (parameter C2). Acting on the value of parameter C1 (see Reading and programming the conﬁ guration parameters) allows the parameters that can be read or modiﬁ ed using the remote control to be selected. The standard value of C1 (default setting: C1=0) allows access to and modiﬁ cation of type P and d parameters and the set point only.

12.1 Description of the remote control

The buttons can be divided into three groups, according to their function.

12.1.2 Buttons for modifying the main parameters (direct access buttons)

The more-frequently used parameters are indicated directly on the remote control, grouped into areas of different colours according to the function. Each modiﬁ able parameter has a button with the + sign and one with the - sign to increase or decrease the value. The buttons without + or - signs only allow the display of the associated value on the control module.

12.1.3 Buttons for the remote control of the control module keypad

The section highlighted in green/blue on the remote control (see Fig. 12.c) reproduces the buttons on the instrument and allows the same operations to be performed remotely; see Reading and programming the parameters of the type H or T control module.

12.2 Programming from the remote control

To activate or deactivate the access code to use the remote control, enter into the control module conﬁ guration mode using password 77 (see Reading and programming the conﬁ guration parameters). Assigning parameter C2 a value other than 0 (from 01 to 99), activates this number as the access code that must be entered each time the remote control is used to program that unit. Obviously, in installations with more than one unit, it is recommended to use a different code for each unit. Setting parameter C2 back to 0 means the remote control can be used without requiring the access code. When not in programming phase, the SEL (limited to the display of the unit of measure), PRG (limited to the function of alarm reset) and the display-only buttons are always active.

12.2.1 Enabling the control for receiving without requiring access code (C2= 0)

Exit the programming phase if necessary, press the START button to enable the remote control; the humidiﬁ er’s control module will show the code for the ﬁ st accessible parameter.

12.2.2 Enabling the control for receiving with access code required (C20)

Exit the programming phase if necessary, press the START button to enable the remote control. All the units located within the operating range of the remote control will display their own access code. To access the programming/reading routine, use the numeric keypad (Fig. 12.b) to enter the access code for the machine to be operated on. Any zeroes must be included (e.g..: if the display shows 05, press the 0 and then the 5 button). If the code is correct, the ﬁ rst accessible parameter is displayed.

12.2.3 Reading the measurements

To directly display one of the measurements featured, press the corresponding button (Fig. 12.d) twice.

12.2.4 Modifying the main parameters (with speciﬁ c button)

With reference to Fig. 12.e:

• press either the + or - button corresponding to the parameter to be modiﬁ ed; the display shows the

parameter code;

• press the SEL button again to display the value;

• then press the + or - button to increase or decrease the value.

The values in the memory of the control module will automatically be modiﬁ ed on exiting the programming phase.

12.2.5 Modifying the main parameters (without speciﬁ c button)

The parameters without a speciﬁ c button can also be modiﬁ ed, proceeding as follows:

• perform the operations for the enabling of the remote control;

• press the  or  button until the code of the required parameter is displayed;

• press the SEL button to display its value; then press  or again to increase or decrease the value;

13. SHUTTING DOWN THE UNIT

When shutting down the unit at the end of the season or for maintenance on the electrical parts and/or plumbing, the humidiﬁ er should be put out of operation. The water should not be emptied from the cylinder before shutting down the humidiﬁ er to avoid the hardening of the deposits contained in the cylinder and thus making them more difﬁ cult to remove.

Follow the instructions below (safety procedure):

• open the disconnecting switch on the power line to the humidiﬁ er;

• open the rocker switch in the lower right of the frame, (see Fig. 13.a) checking that the display on the control module is off;

• close the shut-off tap for the water supply to the humidiﬁ er.

If the cylinder needs to be emptied when shutting down to remove the deposits, before switching off power to the unit, press the DRAIN rocker switch, thus forcing the drain pump electrovalve to open, keeping it in this position manually until the water is completely emptied (see Fig. 13.b).

In the event of malfunctioning of the drain pump electrovalve/ drain pump, the cylinder can be emptied manually, as following:

• humidiﬁ ers up to 10kg/h (22 lbr/h): by removing the connection pipe from the level control housing spigot and slowly draining the water into the collection base-tank of the humidiﬁ er, whereas

• humidiﬁ ers 20-27-40-60kg/h (44-59.5-88-132.2 lbr/h): by unscrewing the cap below the cylinder, (see Fig.13.b).

The cylinder can also be emptied with the appliance closed, proceeding as follows on the control panel:

• turn the unit off using the rocker switch on the lower right of the frame (see Fig. 13.a);

• turn the unit on again;

• within 5 seconds from turning the unit on, press the  and  buttons together;

• after 2 seconds the drain pump electrovalve is activated until the buttons are released; when the buttons are released, the command can be repeated within 5 seconds, otherwise the humidiﬁ er will need to be turned off and on again.

14. MAINTENANCE

14.1 Maintenance of the cylinder-cylinder

For correct operation, the steam production cylinder must be periodically cleaned, at intervals linked to the quantity of salts or impurities dissolved in the supply water. This operation is necessary as the lime deposits that form inhibit the exchange of heat between the elements and the water.

IMPORTANT WARNING: do not use detergents or solvents to clean the components in the cylinder and

all other plumbing.

The unit must be cleaned in any case when the element over-temperature alarm is activated (see ALARMS AND TROUBLESHOOTING), signalled by:

• the lighting up of LED 1 and 3, for the type C control module (see Fig. 15.a);

• the display of the message CL for the type H or T control module.

The cylinder may be hot! Let it cool before handling, or use protective gloves.

To access the cylinder:

• turn the appliance off (Fig. 13.1) and open the disconnecting switch on the power line (safety procedure);

• completely empty the water contained in the cylinder (see SHUTTING DOWN THE UNIT);

• open and remove the casing (see Removing and replacing the front casing).

The layout of the humidiﬁ er is as in Fig. 14.a.

Fig. 14.c

Fig. 14.a Fig. 14.b

To remove and clean the cylinder, follow the procedure as described below:

1. remove the steam pipe from the upper pipe union of the cylinder (Fig. 14.c);

2. electronically disconnect the level sensor (Fig. 14.a, part. no. 3);

3. remove, from the cylinder cover , the pressure equalising pipe with the level control tank (Fig. 14.a,

part. no. 1);

4. remove the protective covers of the element electrical connections (Fig. 17.a, part. no. 5) and

disconnect the power cables;

5. remove the cylinder ground screw (Fig. 14.a, part. no. 5);

6. undo the cylinder fastener by the lifting the black plastic lever (Fig. 14.a, part. no. 2) and pushing it

to the end of its stroke, thus releasing the stop system;

7. lift the cylinder to remove the upper pipe union from the drain unit and remove it from the machi-

ne, paying attention to any drops of water or deposits which may be released from the pipe union;

8. if present, remove the external thermal lining (Fig. 14.a, part. no. 4);

9. place the cylinder on a working surface which is protected by a material resistant to the water and

lime-scale which could be released during the cleaning operations;

10. release the cover ring fastening lever and push it to the end of its stroke (Fig. 17.a, part. no. 11);

remove the metal ring, the plastic cover and its connected parts from the cylinder (see Fig. 17.a that shows the cylinder exploded view);

Cleaning of the cylinder ﬁ lter 20-27-40-60 kg/h (44-59.5-88-132.2 lbr/h):

1. disconnect the pump power supply cable and the connection to the drain pipe;

2. remove from the ﬂ ange the level sensor pipe;

3. unscrew the fastening screws of the ﬂ ange;

4. remove the ﬂ ange from the cylinder and clean theﬁ lter;

To remove and clean the cylinder of the humidiﬁ ers from 20-27-40-60 Kg/h (44-59.5-88-132.2 lbr/h), follow the procedure as described below:

1. remove the cover of the machine (hydraulic side) unscrewing the screws (Fig. 14.b);

2. remove the steam pipe from the upper pipe union of the cylinder (Fig. 14.c);

3. electronically disconnect the level sensor (Fig. 14.a, part. no. 3);

4. remove, from the cylinder cover, the pressure equalising pipe of the level control (Fig. 14.b, part. no. 1);

5. remove the protective covers of the heating element electrical connections (Fig. 17.c part. no. 1) and disconnect the power cables;

6. remove the cylinder ground screw (Fig. 14.b, part. no. 5);

7. if present, remove the external thermal lining (Fig. 14.b, part. no. 4);

8. remove the use ﬂ ange (see ﬁ lter cleaning);

9. remove the cylinder making it run on the din rails;

10. place the cylinder on a working surface which is protected by a material resistant to the water and lime-scale which will be released during the cleaning operations;

11. remove the plastic cover and its connected parts from the cylinder Before handling the elements, ensure that they are not hot! Use protective gloves if necessary.

12. Remove the non-stick ﬁ lm (optional), if present, from the internal wall of the cylinder, and eliminate any lime deposits from this using a jet of water (see Replacing the components

13. for humidiﬁ ers up to 10 kg/h /22 lbr/h unscrew the ring nut on the lower cylinder pipe union and remove the bottom ﬁ lter, which can be reused after cleaning any deposits; the gasket can be reused or, if damaged, can be replaced and ordered as a spare part (Fig.17.a, part. no.13-14 o Fig.17.b, part 12- 13);

14. the elements can also be cleaned without removing them from the upper cover; to do this, after having removed the ﬂ aky portion of lime, immerse the heating elements in a warm 20% solution of acetic acid for 30 minutes, removing the remaining surface deposits with a non-metallic spatula, then rinse well; if the plates are Teﬂ on-coated, avoid using any type of metal tools so as to not damage the non-stick layer;

15. if necessary, the elements can be removed by unscrewing the fastening nut which holds them to the plastic cover; in this case the seal gasket should be replaced;

16. remove the deposits and rinse the internal walls of the cylinder and the probe wells.

15. ALARMS AND TROUBLESHOOTING

15.1 Alarm summary table

When an alarm is activated a message identifying the alarm is displayed on the control module. In the case of potentially dangerous alarms, the control module automatically shuts the humidiﬁ er down. For some alarm events (see Table 15.a), the signalling of the alarm is accompanied by the activation of an alarm relay, as described in: Other auxiliary contacts. If the cause of the alarm is no longer valid, the humidiﬁ er and alarm relay output can be reset automatically or manually, according to the type of problem, while the message displayed is deactivated manually by pressing the reset-PRG button. If no longer active, the alarm status continues to be indicated until the reset-PRG button is pressed.

Still active alarms can not be reset.

In the type C control module the presence of an alarm is indicated by the lighting up of LED 9 and a combination of the LEDs 5 (Fig. 15.a); in the event of more than one alarm, these are indicated in sequence, at 2 second intervals.

In the type H or T control module, if not in programming phase, in the presence of an alarm LED 9 (see ﬁ g. 15.b) begins ﬂ ashing, while the display 5 indicates the alphanumeric alarm code. The message is displayed cyclically, for a duration of two seconds, alternating with the measurement normally displayed (if the measurement normally displayed corresponds to a disconnected probe, the measurement is not displayed; this will automatically return to the display if the probe is reconnected). In the event of more than one alarm, the display indicates all the corresponding codes in sequence, at two second intervals. The alarm Ec cannot be reset. In the event of the alarm CL (regular maintenance required), the alarm can be reset only by resetting the hour counter; see Resetting the hour counter.

The alarm E1 may appear in two distinct cases:

1. Malfunction when reading from the parameter memory (typically on start-up) The default parameters are temporarily recalled, without being saved in the parameter memory (the parameters can be accessed and the correct values restored). In any case the default parameter recall procedure is recommended; see Recalling the default parameters.

2. Malfunction when writing to the parameter memory (typically on pressing the PRG button) Any modiﬁ cations made will be cancelled; the parameters can be accessed, the values modiﬁ ed and save operation repeated.

17.2 Replacing the components

17.2.1 Non-stick ﬁ lm

If requested as an option, the internal wall of the cylinder is lined with a non-stick ﬁ lm to avoid lime being deposited on the internal walls of the cylinder. To clean or replace the ﬁ lm, remove the cylinder following the procedure described in Maintenance of the cylinder-cylinder and then:

• slowly remove the ﬁ lm towards the mouth of the cylinder, without forcing it to avoid damage;

• open the ﬁ lm after having released the click-on couplings;

• clean the ﬁ lm with water and a plastic spatula if necessary; replace the ﬁ lm if damaged;

• wind the ﬁ lm around itself, reinserting the click-on couplings, and place it into the cylinder after the latter has been carefully cleaned and freed from deposits.

17.2.2 Elements

To replace the elements remove the cylinder following the procedure described in Maintenance of the cylinder-cylinder and loosen the fastening nuts from the threaded spigots of the elements. Before reassembling the elements, check the state of the gaskets and replace them if necessary.

17.2.3 PTC overtemperature sensor

The PTC sensors (one for each heating element) do not require regular maintenance; they should only be replaced if the safety thermostat is activated due to operation without water: in fact, the intervention of just one PTC will cause the control module to shut-down operation. To replace the sensors, remove the cylinder following the procedure described in Maintenance of the cylinder-cylinder and then:

• disconnect the PTC sensor terminals (see Fig.: 7.p.a to 7.p.n);

• remove the electrical elements corresponding to the sensors being replaced;

• unscrew the PTC sensor (ﬁ g. 17.a, part. no. 7 or Fig. 17.b part. no. 7 or Fig. 17.c part. no. 2) using a spanner on the hexagonal spigot, accessible from the under side of the cover;

• reassemble a new PTC sensor, replacing the o-ring and screwing it tight; reconnect the terminals;

• reposition the electric heating elements, making sure the PTC sensor enters into the corresponding sheath in the aluminium casting.

17.2.4 NTC temperature sensor (version with type H or T control module only)

As for the PTC sensors, the NTC sensor controlling the water temperature does not require regular maintenance. To replace this sensor, remove the cylinder following the procedure described in Maintenance of the cylinder-cylinder and then:

• disconnect the terminals of the NTC sensor (see Fig.: 7.p.a to 7.p.n);

• remove the sensor from the well housed in the measuring sheath (ﬁ g. 17.a part. no. 2, or Fig. 17.b part. no. 1, or Fig. 17.d part. no. 11);

• reposition and connect the new sensor in the place of the old one.

17.2.5 Fuses (uxiliary circuit)

These measure 10.3 x 38mm and are housed in the fuse cartridge; to check the state of the fuses, check their continuity using a tester. Use the types of fuses indicated in table 17.e.

17.2.7 Solid state relays (version with type H or T control module only)

The solid-state relays (one in the single-phase unit, two in the three-phase unit) can malfunction in one of two ways: by short-circuit or burn-out. The respective consequences for the supply of power are: continuous conduction or permanent opening. In the event of malfunctioning, check the conduction of the relay using a tester. For the replacement of the solid-state relay:

• turn the humidiﬁ er off;

• open the disconnection switch in the power line (safety procedure);

• disconnect the power and auxiliary cables from the solid-state relay terminal block;

• remove the relay from the electrical panel by using a screwdriver to lower the fastening lever to the omega guide;

• replace the new relay on the omega guide and reconnect the wires as before.

17.2.8 Cooling fan and circuit breaker (version with type H or T control module only)

The SSR relays are cooled by a fan placed in the upper part, on the right side of the machine for the 20-60kg/h (44-132.2lbr/h) models, or placed on the base of the humidiﬁ er for the models up to 10kg/h (22lbr/h). With insufﬁ cient ventilation the temperature of the electrical panel may rise excessively until, reaching 65°C, power to the solid-state relays is cut by a special Klixon (heat sensor, used in this application as circuit breaker - hereafter: circuit breaker), with manual reset (indicated by S2 in the wiring diagram) and without an activation signal. In this case, check:

• Whether the thermoprotective placed in the din rail near to the SSR relays has been working, or placed in front of the bafﬂ e pressing the reset button (see Fig. 17.f);

• that the fan power board, ﬁ tted in front of the bafﬂ e, is powered (input terminals: 24 Vac) and in turn powers the fan (output terminals: 24 Vdc), (only for models up to).

If the fan is faulty:

- in the models up to 10 Kg/h (22 lbs/h):

• remove the bafﬂ e, after having unscrewed the two side nuts for fastening to the partition of the

appliance;

In case of malfunction, the thermoprotective can be replaced unscrewing the fastening screws;

- in the 20-27-40-60 Kg/h

( 44.1-59.5-88.1-132.3 lbs/h ) models:

• unscrew the 4 fastening screws placed on the right side of the structural work and extract the fan

from the inside of the panel. In case of malfunction, the thermoprotective can be replaced removing the polycarbonate transparent protection of the solid state relays and unscrewing the fastening screws.
