A Word about Water Quality

The mode of operation of all electrode steam humidifiers is based on the fact that water contains minerals and is therefore conductive.

• "normal" tap water is ideal.

• but what is "normal" tap water exactly? Users of HygroMatik units in the most diverse areas consider their tap water "normal."

HygroMatik typically defines "normal" as feed water with a conductivity between 200 and 500 µS/ cm (microSiemens per centimeter) at 15° C.

Some areas, however, are supplied with tap water whose quality is outside th e parameters specified by HygroMatik. If the HygroMatik steam humidifier's control is not adjusted correctly in these areas, the unit cannot perform optimally. For example, the electrodes could wear out particularly quickly or the steam production could be too low.

The operational parameters set by HygroMatik in the factory are intended for normal tap water. However, they can very easily be reprogrammed to fit the special requirements of a particular area. In addition, it is possible to install a plastic star in the cylinder in order to increase the life span of the electrodes or to provide a flushing mechanism to extend maintenance intervals.

Because of this you should monitor your new unit during initial operation. Make sure that it has been properly installed and is operating to your satisfaction.

Consult your HygroMatik specialists. We will test the quality of your water and advise you on installation and initial operation. Your HygroMatik steam humidifier will be carefully adapted to your particular application.

Warning, Hazardous Voltage: All work to be performed by trained personnel only. All electrical installation and servicing of the electrical components of this unit to be performed by qualified electricians only. Disconnect power supply before installation and servicing!

4. Operation and Installation

4.1 Mode of Operation

The HygroMatik steam humidifier utilizes the conductivity normally present in tap water for steam production. Electrodes inside an enclosed steam cylinder are immersed directly into the tap water. They are connected to the alternating current.

The conductivity of the water generates an electric current between the electrodes. In this way, the electric power supplied is converted directly into heat without energy loss.

The amperage is a function of the available voltage, the immersed electrode surface area, the average distance between the electrodes and the water conductivity. The steam output of the humidifier is determined by electric power usage, which is regulated by increasing or decreasing the immersed surface area of the electrodes.

Concurrently, a self-regulating control keeps conductivity within a specified range.

The steam produced has a temperature of about 100°C with minimal excess pressure ("pressureless steam"). It is largely free of minerals and germ-free. Mineral deposits typically remain behind in the cylinder.

4.2 Installation and Operation

By pressing the control switch („Pos. I”) the humidifier is turned on. When the controller specifies an increase in humidity, the main contactor is switched on and the electrodes (48) are supplied with power. The water inlet solenoid valve (25) feeds water into the steam cylinder (16+19).

As soon as the electrodes are immersed, the current begins to flow. The water is now heated. When the pre-selected output is reached, the control turns off the solenoid valve and interrupts the water supply.

After a short heating up period, the water between the electrodes begins to boil and vaporize. The vaporization lowers the water level in the steam cylinder, reducing the output provided. The inlet solenoid valve, equipped with a fine mesh filter, intermittently admits fresh water.

Humidifier power usage is continuously monitored. With a cold start-up, the nominal current increases to 125% in order to achieve quick-start output parameters. This activates the electronic overflow limiter which causes a partial draining of the cylinder. This reduces the immersed surface area of the electrodes, lowering power usage.

The concentration of dissolved salts increases over time, which can lead to a rise in the conductivity of the water. If this continues, conductivity may increase until a short circuit occurs. This could damage the unit, but in any case would significantly reduce the life span of the electrodes.

For this reason, regular, periodic blow-downs of some of the concentrated water are very important. Following this procedure as recommended provides stable cylinder water conductivity as well as minimal water loss for the expected service life of the cylinder.

Water blow-down is performed by a blow-down pump (32). The functioning of the blow-down pump is continuously monitored during operation. If the pump is damaged, the steam humidifier shuts down.

With normal water quality, the blow-down loss rate is between 7% and 15% of the amount of steam produced. The steam cylinder requires complete drainage every 3-8 days, regardless of the water quality.

Mineral deposits settle in the open area below the electrodes and are removed through periodic maintenance. The blow-down pump itself has wide openings and can flush out smaller pieces of mineral deposit. This extends the service life of the unit and reduces the required maintenance interval.

During blow-downs, water flows from the pump into the drainage system.

A sensor electrode (10) monitors the maximum

water capacity

of the cylinder. When the water level reaches the sensor electrode, the water supply is interrupted. This can occur when the water has low conductivity or when the electrodes are worn out. In the case of low water conductivity, however, this state usually lasts only a short time. The built-in control and the large area electrodes combine to produce a rapid rise in conductivity by increasing the concentration of the water.

The steam cylinder consists of a top (16) and lower (19) part joined with a cylinder flange. The seal between the cylinder and cylinder base (37), as well as between the top and lower part of the cylinder, is maintained using an o-ring (35+17).

For maintenance the cylinder can be drained by pressing the control switch „Pos.II”.

5.3 Absorption Distance BN

The "absorption distance" (BN) is defined as the distance from the steam feed to where the steam is completely absorbed in the

treated air. Inside the absorption distance, steam is visible as mist in the air stream.

Condensation may collect on anything installed inside the absorption distance.

Although steam outside the absorption distance (B

) is com-

pletely absorbed, it is not yet evenly diffused in the duct. If you plan to install any parts or devices inside the absorption distance, such as sensors or elbows, we recommend increasing the absorption distance using the formulae below. The absorption distances required for certain installed fittings are distinguished by separate symbols and calculated as a multiplier of the absorption distance B

The absorption distance has no fixed value, but depends on many factors. These are depicted in the absorption distance nomogram below.

5.3.1 Determining the Absorption Distance

To determine the absorption distance, the following parameters are required:

• Air humidity before humidification x

in g/kg.

• Air temperature after humidification t

in °C (with steam

humidifiers the change in air temperature due to humidification may be disregarded t

or t2).

• Specific increase in humidity x in g/kg (can be determined in the h,x diagram)

• quantity of steam introduced in kg/h.

• air speed w

in m/s in air duct

• Total length l

of the steam manifold installed in the air

duct

Absorption Distance

for normal obstructions, such as sensors, ventilators, outlets

= (1,5...2) x BNfor fine filters, heat registers

= (2,5...3) x BNfor particle filters

= (2,5...3) x BNfor humidity sensors, duct humidistats

Page 19

Length ID of the usable steam manifold depends on the dimensions of the air duct. The length of the absorption distance can

be reduced by using multiple steam manifolds (also see section on the steam manifold).

Method:

Graphically determine absorption distance B

using the absorp-

tion distance nomogram (also see Section „Absorption Distance Nomogramm“). Enter the value of the parameters enumerated above into the respective quadrants. The resulting point of intersection indicates the value of the desired absorption distance B

• Maximum allowable pressure in the air duct is 1200 Pa.

• On the return side, the maximum allowable negative air

pressure is 500 Pa. Placement of the steam manifold on the supply side of the air duct is preferred.

• With high-pressure air-conditioning systems, the unit's

drain hose system must be modified depending on the over pressure. When this is the case please consult HygroMatik.

• Install the steam manifold as close as possible to the

steam humidifier in order to minimize steam loss through condensation.

• Depending on the design of the air duct, additional moun-

ting of the steam manifold may be required. Shown installation and position dimensions are based on experimental values. Special environmental conditions could require adjustments.

• We note that the German Association of Engineers (VDI)

Guideline 6022 specifies a water drain within the absorption distance inside the air duct.

• For steam bath applications: Install the steam manifold

safe from contact with people in order to prevent injuries or burns. Do not install the steam manifold near a tempera-

ture sensor or inaccurate readings may result.

• Air flow rates over 3m/s can possibly lead to condensate

drainage problems at the steam manifolds which may require adaptation measures.

steam outlet of the HygroMatik steam humidifier (do not restrict the cross-section, otherwise back pressure will increase).

• The steam hose must be without sags and kinks and be

laid with a continuous slope of 5-10% (otherwise sags will be formed).

• The steam hose should be as short as possible. In case of

lengths of over 5 m the hose should be insulated to avoid excess condensation.

• In the case that steam output is distributed on two steam

manifolds the T-pieces for the steam and conde nsate hose should be installed near the manifolds. If the installation is carried out in this way only one steam hose is necessary for the main part, loss of condensate will be decreased.

• Depending on how the hose is laid, hose clips should be

set at intervals of approx. 500 mm.

• Allow access to the steam hose, so that it can be inspec-

ted later.

• In case of straight lengths of several meters, it is recom-

mended to place the steam hose in temperature resistant plastic pipe (40 mm dia for hose DN25; 60 mm dia for hose DN40) or to use copper pipe.

• Only genuine HygroMatik hoses are capable of withstan-

ding the operating conditions. Allow for minimum bending radii: Steam hose DN 25: Rmin = 200 mm Steam hose DN 40: Rmin = 400 mm

5.8 Condensate Hose

Note: When installing the condensate hose, please pay atten-

tion to the following:

Warning: To keep condensate from accumulating in the duct, make sure condensate can drain freely.

If the steam manifold is positioned higher than 500 mm above the steam humidifier:

» Remove the condensate plug (12) from the connection

fitting on the cylinde.

» Lay the condensate hose at an approximate incline of

5-10% to the steam cylinder connection fitting, to allow the condensate to drain freely.

Note: It is recommended to form a loop of 200 mm diameter as a vapour trap provided there is enough space.

If the steam manifold is positioned lower than 500 mm above the steam humidifier:

» The condensate must be drained separately. » To prevent steam loss, lay a loop at least 200 mm in di-

ameter.

» To ensure condensate drainage, place the loop (vapor

trap) as far away as possible below the steam manifold connection.

» The condensate connection on the steam cylinder (16 +

19) must be closed with a sealing cap.

» Place hose clamps at intervals of at least 500 mm, de-

pending on how the hose is laid.

5.9 Types of Installation

The steam manifold is positioned higher than 200 mm above the steam humidifier.

» Lay the steam hose at a height of at least 400 mm and

then connect to the steam manifold with a constant rise or fall.

» Lay condensate hose with a slope to the steam cyl-

inder.

5.10 Steam Solenoid Valves

When humidifying a number of loads, which are to be controlled separately, using a single steam humidifier, steam solenoid valves can be included in the steam hoses. Valve control has to provided by the customer.

• Install the vertical risers with flow from bottom to top.

• The best position is just above the steam humidifier.

Installation of Steam Solenoid Valve

5.11 Unit Installation Check

Attention: This unit may only be operated by qualified and prop-

erly trained personnel. Please check the installation using the following list:

 Does unit hang vertically?  Are wall distances to the unit within the range  Does steam hose have a slope of 5-10%?  Is condensate hose installed with a loop of min. 200

mm?

 Is steam manifold positioned correctly? Are all bolts and

clamps tightened?

Page 33

6. Water Installation

Warning: When installing the water installation, note the follow-

ing:

• Have all work performed by a professional.

• Disconnect power supply before installation.

• Obey local public utility

regulations

• Verify that necessary safety measures have been taken – in compliance with either German Technical and Scientific Association for Gas and Water (DVGW) guidelines (DIN EN1717) or local regulations – to eliminate backflow of polluted water into drinking water treatment facilities. This can mean installing a backflow preventer . Within the humidifier, a double check valve (58) is located in the water supply line. It prevents - in accordance with DIN EN 61770 - the backflow of water.

• Use feed water without chemical additives and with a conductivity between 200 and 800 µS/cm only. Above conductivity levels of 800µS/cm to a maximum of

1250µS/cm and below conductivity levels of 200µS/cm to a minimum of

125µS/cm, special adjustments are

required. In this case please contact HygroMatik.

• The water supply temperature may not

exceed 40° C.

• Water installation pressure: 1 - 10 bar (100 x 10

to 100

x 10

pascal).

• Blow-down water must be able to drain.

• For water installation please use the water connecting

hose that is delivered with the unit.

6.1 Operation with Softened Water

Warning: Unless special measures are taken, feeding softened

water into the HygroMatik steam humidifier is dangerous. It can cause

• unacceptably high conductivity

• the formation of salt bridges between the electrodes

and the electrode leads on the inner surface of the top part of the steam cylinder

• foaming in the steam cylinder

Salt bridges cause electrical arcs. These are indicated by the presence of black grooves in the top part of the cylinder. The top part must be replaced to prevent further damage to the cylinder material, as well as short circuits which trip main circuit breakers.

Foam comes into contact with the maximum water level sensor electrode and triggers a signal indicating the cylinder is filled to capacity, even though this is false and the nominal current has not yet been reached.

Page 34

Note: Please contact HygroMatik if you wish to operate the unit with softened water.

If using a water softening system, we recommend diluting the softened water with normal tap water to produce an overall hardness between 4-8°dH. This value can be set lower if the water does not foam.

When blending softened water with deionized water (conductivity = 5-20 µS / cm) it is to ensure that the mixture neither foams nor is too low in conductivity.

When feed water contains softened water, the level of conductivity is typically higher at operating temperature. Install a HygroMatik "cylinder star" to extend the service life of the electrodes.

6.2 Water Supply

» Install a shut-off valve (SV) in the supply line. » Install a water filter (WF) if water quality requires it. Note: Shut-off valve (SV) and water filter (WF) are not supplied

with the unit

» HygroMatik provides a water hose (56) with a cap nut at

both ends which can be used for water installation.

Install as follows: » Screw and tighten the cap nut with its inner seal ring

around the water supply screw connection that protrudes from the base.

Note: Tightening too much will destroy the fitting. The valve strainer must be placed inside the solenoid valve.

Page 35

» Use a cap nut (internal thread ¾“) with inner seal for a

customer-provided water installation.

6.3 Water discharge

Warning: During blow down hot water with a temperature of

about 95°C is being drained. If touched this can cause burns to the skin.

Warning: Pay attention for free and non-pressure drainage of the water! During blow down up to 0,3 L/sec are being drained. For water discharge, we recommend installation of a flexible water drain hose. Humidifier and wastewater discharge must be on the same pressure level.

Please note:

• Do not bend the drain hose.

• Install discharge line and drain pipe made from temper-

ature resistant material (to 95° C).

Install water discharge as follows

• Loosely insert a length of 1 1/4 " drain hose, approx. 250 - 1000 mm, into a drain pipe with a minimum inner diameter of 40 mm and seal with a rubber gasket.

• Fit water drain hose over the pump drain hose and fasten to the housing drain connection.

A grounding clip is fixed on the inner surface of the housing drain connection. The end of the pump drain hose is pushed into this clip. During blow-down, the grounding clip is in direct contact with the water and shunts potential residual electric currents away from the housing.

min.: 250mm max.: 1000mm

Page 36

There is a 3mm-wide crack between the pump drain hose jacket and the inner surface of the housing drain connection. If water collects in the base plate, it will flow through this crack into the drainage system.

6.4 Water Installation Check

Go down the following water installation checklist:

 Are all screws and clamps properly tightened?  Is the water supply pipe flushed?  Was the water installation correctly installed?  Can the blow-down water drain freely?  Was the water discharge correctly installed?

 Is there no leakage from the water supply pipe and

water discharge?

Warning: Flush the water supply pipe before connecting to the solenoid valve, especially a newly installed pipe. This prevents premature damage.

Page 37

7. Electrical Connection

Danger, Haza rdous Voltage: All work related to electrical inst al-

lation to be performed by authorized personnel only (electricians or professionals with equivalent training). The customer is responsible for checking qualifications.

Danger, Hazardous Voltage: Do not plug the steam humidifier into the power grid until after all installation work has been completed.

Please obey all local regulations concerning electrical installation.

Warning: The electronic components of the humidifier control are very sensitive to electrostatic discharges. In order to protect these components during any type of installation, steps must be taken to guard against damage from electrostatic discharge (ESD protection).

Warning: For electrical installation, note the following:

• Disconnect power supply before installation and protect against restart.

• Verify the absence of electric current.

• Make sure the unit is switched off before installing or

removing the display plate or basic PCB.

• Professionally lay electrical connector cable.

• Install the electrical connections according to the wiring

diagram.

• For units with rated power over 33 kW, only a permanent connection to a permanent wire is allowable (German Association for Electrical, Electronic & Information Technologies [VDE] Standard 0700 Section 98).

• Verify that all terminals have been tightened.

7.1 Electrical Installation

» Fuses must have a contact gap of at least 3mm per

pole.

» Install a separate main connection for each steam cylin-

der, complete with main contactor, main switch, etc.

7.2 Safety Interlock

Note: Install contact interlocks, i.e. max. hygrostat, vane relay,

pressure controller, air interlock, in series between terminals 1 and 2.

Warning: A max-hygrostat shou ld be installed in the safety interlock. The max-hygrostat acts as a safety device in case the humidity sensor malfunctions.

Warning: Contacts laid between terminals 1 and 2 must be potential free and rated for 230V switches.

7.3 Wiring Diagram

Please remove the wiring diagram from the technical manual supplied with the control used with your humidifier. Every steam humidifier comes with one technical manual for the unit and one for the control.

7.4 Electrical Installation Checklist

Perform electrical installation checks in compliance with customer site requirements and public power utility regulations:

 Is the power grid voltage compatible with the voltage on

the name plate?

 Have all electrical connections been made according to

the terminal connection diagram?

 Have all electrical cable and plug connections been

properly tightened?

 Are all electrical socket connections secure?  Is the unit grounded?

After this check the unit can be switched on. Warning: The unit must be closed and locked. This guarantees

that the cover is grounded. (only humidifier type HyLine and MiniSteam)

Note: For initial operation, control, service, malfunctions, and circuit diagrams, consult the operation instructions for the HygroMatik-controls.

Page 41

8. Maintenance

The HygroMatik steam humidifier is easy to maintain. However, inadequate or improper maintenance can lead to operational malfunctions. Perform regular maintenance to give your unit a long life span.

Warning: When performing maintenance work, please note:

• During operation and also for a while after switching off the unit the steam cylinder is hot. Before touching the cylinder, check its temperature.

• Drained cylinder water could have a temperature up to 95°C.

• Leakages within the humidifier could lead to leakage currents.

• Observe safety notes.

• Switch off the unit before maintenance and protect

against restart.

• After maintenance work, have qualified personnel check that the unit is operating safely.

The steam humidifier's performance and maintenance intervals primarily depend on the water quality (carbonate hardness, conductivity) and the quantity of steam produced since the last maintenance. Abnormal water quality can shorten or lengthen maintenance intervals. Ongoing maintenance intervals can be estimated based on the amount and type of residue found in the steam cylinder.

Indications that cylinder maintenance is required immediately include:

Control Indicator

L maintenance message: red LED is blinking:

- Cylinder-Full, delayed *,

- Blow-down Fault *,

Filling Fault *.

Unit has switched itself off automatically.

Page 42

8.1 Maintenance Work

Mineral deposits precipitate and crystallize very differently in different types of water, even when two types have the same conductivity and hardness levels (the various constituents in the water interact differently).

Instructions on maintenance and cleaning intervals, or on electrode service life, are based entirely on empirical data.

In most cases, the conductivity levels given in Section 1.1 "Directions for Use" of these instructions can be considered normal. Individual parameter setting of the control may be necessary.

In extreme cases, water pretreatment may be necessary (softening by dilution to approx. 4 - 8 °dH; decarbonization/partial desalination to achieve target reductions in carbonate hardness). HygroMatik would be pleased to refer you to companies specializing in water treatment systems.

8.1.2 Electrode Wear

Electrode wear is dependent on:

• feed water quality (conductivity and hardness) and

• generated amount of steam.

Attention: The electrodes must be exchanged at the latest if the display shows the message Service (red LED is blinking). The unit is switched off in case it senses a period of one hour's operation in the "Cylinder full" condition. As a guide they must still be a third to one half their original length.

The original length of HygroMatik stainless steel large-area electrodes is as follows:

Uneven Electrode Wear

Replace badly worn electrodes completely. Check main fuses ! If a main fuse has blown the corresponding electrode will not be

supplied with power and hence will not wear.
