Caution

We recommend that:

S the manual is retained for the entire service life of the machine; S the user reads the manually carefully before carrying out any operations on the machine; S the control is used exclusively for the purpose for which it is intended; incorrect use of the control shall release the manufac-

turer from any liability.

This manual has been prepared to enable the end−user to carry out only the operations that can be made with the panels closed. Any operations that require the opening of doors or equipment panels must be carried out only by qualified personnel. Each machine is equipped with an Electric Insulating device which allows the operator to work in conditions of safety. Switch off the machine before any maintenance operation to eliminate risks remaining (electric shocks, scalds, automatic restarting, moving parts and remote control).

For "UNDER" units installed on raised floor: switch off the machine before removal of the floor panels within a distance of 850 mm from the machine, to avoid risks of contact with rotating devices.

The panel key supplied with the unit must be kept by the person responsible for maintenance. For identification of the unit (model and serial no.) in case of the necessity for assistance or spare parts, locate the identification

label on the outside of the unit.

IF THE TUBING IS TO RUN OUTDOORS, ADD ETHYLENE GLYCOL TO THE CIRCUIT AS DESCRIBED IN PARA. 4.4.

4.2 − Auxiliary water connections

− Condensate drain (Fig. 1):

S Use galvanized steel, PVC or flexible polythene

tubing.

S Allow a 2% gradient towards the drain outlet. S There must be a drain trap (1) placed at least 30

mm below the drain tray (2).

S Fill the drain trap with water (3).

Fig. 1 − Condensate drain

min. 30 mm

S Place shut−off ball valves (3) at the conditioner in-

let and outlet to allow easy maintenance.

S It is useful to install a thermometer (4) and a ma-

nometer (5) at the conditioner inlet and outlet.

S Install a water drain tap (6) at the lowest point in

the circuit.

S Place a control valve (7) in the outlet water tubing. S Fill the circuit with water/glycol (see below), up to

a maximum pressure of 7 bar.

NOTES:

S To avoid stratification run the circulation pump for

at least 30 min. after adding any glycol.

S After adding water to the water circuit, disconnect

the unit from the sanitary water piping system; in

this way the water mixed with glycol won’t return into the same piping system.

S After any topping−up of water check the glycol

concentration and add any glycol if necessary.

S The hydraulic features of the system vary by adding

glycol. Therefore check the head and the flow rate of the pump to be used.

NOTES:

S The cables have to be sized in compliance with local standards and according to the type and characteristics (e.g. Amperes) of installation. S The specific power the user−installed switch allows must be lower than 300,000 A2 x s. S Prescriptions on the differential relay required to the user:

S for special places (healthcare facilities, etc...) comply with the local regulations; S For ordinary places, a low sensitivity is suggested (300 mA) coordinated with the value of the ground heater (IEC 364): Ra v 50/Ia (Art.

413.1.4.1, CEI 64−8);

S In case of frequent over−voltages with mains impulse, it is advisable to install a selective differential and to evaluate the need for adopting

other devices.

S (Models 90−10−12−14 U C only) The value of current (Full Load Ampere) is calculated considering electric heaters running at a capacity

of 17,55 kW, configuration F+C and F+C+H.

5.2 − Fan connections

The fan is electrically feeded by an autotransformer that is connected by the constructor in order to obtain the nominal air flow and the Available External Static Pressure (AESP). To change the factory connection proceed as follow:

− identify the unit’s graph;

− check the factory fan blocks connection ( or ) and correct if necessary (see Fig. 12);

− find the output connectors and the bridges corresponding to the graph values (see para. 5.3;

− connect the bridges and the output connectors;

− connect the 400V supply cables to the C" terminals.

− choose the curve’s point where both the air flow and the static pressure are the most suitable for the installation;

After a wiring modification, execute a loadless test on the autotransformer. Check the voltage of each wire, in order not to damage the transformer (always

refer to the output voltage column va-

lues).

N.B. A FAN SPEED VARIATION CHANGES THE WOR-

KING CONDITION OF THE UNIT.

6 − Start−up

6.1 − First start−up (or after long stand-

still)

Start the air conditioner as follows:

1) Open all valves in the water circuit according to the instruction label attached to the valve.

2) Check that there are no water leakages.

3) Bleed all air out of the chilled water circuit using the bleed valve on the chilled water coil.

4) Close all MCBs on the electrical panel.

5) Check the supply voltage on all phases.

6) Start the unit by pressing ON OFF (see Fig. 13).

7) Check the electrical absorption of all components (see Chap. 5).

8) Ensure that the fans rotate in the correct direction (see arrow on fan). CAUTION: risk of contact with rotating devices.

9) Ensure that all control system settings are correct and that there are no alarms (see Control manual).

10)Verify the water flow.

11)Verify the Fresh Air Intake operation (if fitted).

12)Once the system is operating under load, check the various components, as follows:

S Verify that the fans are operating properly. S Ensure that the temperature and relative hu-

midity are being controlled, and that the humidifier (optional) and heating steps (optional) operate when required.

S Ensure that chilled water valve operates when

required.

6.2 − Starting and stopping

Turn on the unit operating on the ON/OFF switch placed on the left case of the unit (Fig. 13). If the ON/OFF remote device is not installed, the green LED on the Microface case will light up together with the LED placed below the ON/OFF switch. The fan starts immediately (the fan always works when the unit is ON); after 2 minutes the regulation is activated, so the cooling (compressor), heating (electric heaters), humidifying and dehumidifying devices can start.

Adjust the set−point as indicated in Control ma-

nual.

Stop the unit putting the ON/OFF switch in OFF.

S The main switch QS should only be switched off if

the unit is stopped for a long period of time.

6.3 − Automatic restart

If desired, the unit will automatically restart on the return of power after a supply interruption (see Control manual).

Fig. 13 − On−Off switch

7 − Operation

Unit operation is completely automatic. The below sequence explains how the unit operates :

S The air, sucked in by the fan(s), enters the unit. S The air is immediately filtered. S The TEMPERATURE sensor or HUMITEMP (tem-

perature + rel. humidity) sensor (check type installed), verifies the state of the inlet air, and relays this information to the control system.

S The control system compares the relayed informa-

tion to the set point and proportional band values programmed into its memory: it then commands the air conditioner to treat the air as follows (see also Control manual):

S COOLING

Chilled water flows through the chilled water coil, thus cooling the air passing over it. The chilled water flow is controlled by a timed modulating (3−way) valve, which regulates the flow rate in order to obtain the exact amount of cooling required.

S HEATING

This can take one of two forms:

− electrical heating (optional): the heating elements heat the air passing over them. There are 3 heating steps.

− hot water heating (optional): if hot water is available, this flows through the hot water coil, thus heating the air passing over it. The hot water flow is controlled by an on−off (3−way) valve.

S DEHUMIDIFICATION − optional

Maximum chilled water flow is requested through the coil, whose temperature drops below the dew point of the air, thus dehumidifying it. If necessary, heating is used to reheat the air.

N.B.: If, during dehumidification, the ambient temperature drops below a specified level, dehumidification will be stopped if necessary (see LOW LIMIT intervention in Control manual).

S HUMIDIFICATION − optional

The humidifier creates steam, which is distributed into the air stream via the steam distribution pipe (see also App. A).

HIMOD−C

English

Page 29

S Filtered new air is injected into the air stream via

the Fresh Air Intake.

S The treated air passes through the fans, which op-

erate continuously, and is then dispersed out of the unit.

S Under unit only: the air passes from the underfloor

void into the room via air distribution outlets.

For "UNDER" units installed on raised floor: switch off the machine before removal of the floor panels within a distance of 850 mm from the machine, to avoid risks of contact with rotating devices (see Fig. 15).

N.B.: Manual control can be performed using the control

system (see Control manual).

Fig. 14 − Position of the chilled water valve actuator

ment with 3 mm allen key

7.1 − Chilled water valve

The 3−way valve controls the chilled water flow. It operates as follows (Fig. 14):

S When the valve is fully open (i.e. max. chilled water

flow) the actuator slot is set to ’1’.

S When the valve is closed (i.e. no chilled water flow)

the actuator slot is set to ’0’.

The valve running time is set to the value specified in the Control Manual.

Note 1: In the unlikely event of control system failure, the valve can be manually controlled by means of a 3 mm allen key placed into the actuator slot. NEVER PERFORM THIS OPERATION USING A SCREWDRIVER.

Note 2: For models 90−10−12−14 UC the chilled water valve is not foreseen for the manual operation. When actuator stem is completely down the valve is closed (by−pass 100%), when actuator stem is completely up the valve is open (by−pass 0%) and all water flows into the coil.

App. A.4 − Start−up and operation

App. A.4.1 − Start−up

Before using the humidifier, check the following:

S Supply and drain connections. S That the cut−off tap is open. S All wiring. S Earthing. S Steam hose connection between steam cylinder

and distributor.

To start the humidifier simply switch on the air conditioner, which will in turn automatically start and stop the humidifier as required. The (adjustable) parameters which determine humidifier operation have already been factory−preset (see HIROMATIC manual).

App. A.4.2 − Operation

Water, provided it contains even a small quantity of salts in solution, is a conductor of electricity. Therefore, if the steam cylinder is filled with water and a potential difference is applied between the production electrodes, the water behaves like an ordinary electrical resistance and becomes hot, thus creating steam. The steam production rate can be controlled by varying the water level in the cylinder; the higher the water level, the deeper the electrodes are immersed into it and the greater the steam production.

Note 1

In case of low water conductivity the cylinder 93H (9.0 kg/h) or 53H (4.5kg/h) can be substituted with the cylinder 93L or 53L without changing the power supply. Please remember to set the right cylinder type into the Control system. The steam production will remain unchanged.

Note 2

When starting with an empty cylinder, the water conductivity is normally insufficient for the HUMIDIFIER STEAM OUTPUT to be reached immediately. Therefore the humidifier produces as much steam as possible to fill the cylinder completely. Any evaporation water is immediately refilled. The drain valve is kept shut and therefore, as the steam does not contain any salts, the conductivity of the water within the cylinder slowly increases until the HUMIDIFIER STEAM OUTPUT is obtained. The length of the start−up period depends upon the water conductivity. For very conductive water it may occur that the HUMIDIFIER STEAM OUTPUT is obtained immediately.

App. A.5 − Maintenance

App. A.5.1 − Removing the steam cylinder

To remove the steam cylinder, proceed as follows (see Fig. 3):

1) Open the General Switch relative to the humidifier.

2) Drain all the water from the cylinder by activating "HUM. DRAIN" in the HIROMATIC Service menu several times (see Microface manual).

3) Disconnect the steam hose (S) (made of non−conductive rubber).

4) Disconnect the power electrode wires (P) and level sensor wire (L).

5) Undo the clip (R).

6) Pull the cylinder (C) out of its gland at the bottom (G).

App. A.5.2 − Replacing the steam cylinder

When the steam cylinder is approaching the stage where it needs to be replaced, warning A25 is generated (see HIROMATIC manual) to advise the user that the cylinder must be replaced. To replace the cylinder, proceed as follows (see Fig. 3):

1) Carry out the instructions in para. Removing the steam cylinder.

2) Using the new cylinder, carry out 4)−6) of para. 5.1 in reverse order.

3) Connect the steam hose (S); the clip on the hose needs to be tightened only slightly.

4) Manually switch the humidifier on for 2−3 minutes (in the HIROMATIC Service menu). Then switch it off.

5) Drain the water as for 2) in para. Removing the steam cylinder.

6) If the air conditioner features a HIROMATIC with Graphic display, reset the humidifier working hours (window no. 1 of PARAMETE R ME NU) to zero.

7) Close the General Switch relative to the humidifier.

App. A.5.3 − Annual maintenance

Annually (e.g. before any close−down period) carry out the following service on the humidifier (see Fig. 3):

1) Carry out the instructions in para. Removing the steam cylinder.

2) Disconnect the supply (F) and drain (D) valve wires.

3) Unscrew and remove the drain tank (T).

4) Unscrew the drain valve assembly screws (V).

5) Remove the drain valve assembly.

6) Unscrew and remove the drain valve solenoid (O).

7) Unscrew and remove the drain valve armature (A).

8) Clean all parts of the drain valve using a commercially available descaling agent (to remove any incrustations).

9) Detach the hose from the supply valve.

10)Remove the supply valve connection (N).

11)Unscrew the supply valve (F) and remove it.

12)Clean the supply valve using a jet of water.

13)Replace any hose which has become hard and brittle.

14)Thoroughly flush the drain line (E).

15)Reassemble the humidifier by carrying out the above instructions in reverse order.

ATTENTION

Always empty the cylinder completely before any close−down period.
