The appliance should be installed in accordance with national wiring regulation.

SAFETY CONSIDERATIONS

1. When working on air conditioning equipment, observe precautions in this manual, and on plates and tables attached to the unit. Follow all safety codes and other safety precautions that may apply.

2. Installing and servicing air conditioning equipment should be done by trained and qualified service personnel only. Untrained personnel can perform only basic maintenance functions such as cleaning coils, filters and replacing filters.

3. Ensure that the electrical supply and frequency are adequate for the operating current required for this specific installation.

WARNING - Before any service or maintenance operations turn off the main power switch.

1. The manufacturer denies any responsibility and warranty shall be void if these installation instructions are not observed.

2. Never switch off the power main supply when unit is operating in the cooling cycle. To switch off the fan coil unit use only the ON-OFF button.

3. This avoids over-flow in the drain pan, by allowing the pump to drain any condensate water due to regulating valve losses when chiller is working.

BEFORE INSTALLATION

The installation site must be established by the system designer or other qualified professional, taking account of the technical requisites and current standards and legislation.

PCE fan coils must be installed by an authorized company only.

PCE fan coils are designed for installation in a false ceiling, for intake of fresh air from outside and for deviation of a small part of the treated air for discharge in a neighboring room.

They must be installed in such a way as to enable treated air to circulate throughout the room and in respect of the minimum distances required for technical maintenance operations.

1. It is advisable to place the unit close to the installation site without removing it from the packaging.

2. Do not put heavy tools or weights on the packaging.

3. Upon receipt, the unit and the packaging must be checked for damage sustained in transit and if necessary, a damage claim must be filed with the shipping company.

4. Check immediately for installation accessories inside the packaging.

5. Do not lift unit by the condensate drain discharge pipe or by the water connections; lift it by the four corners.(Fig.1)

6. Check and note the unit serial number.

Fig.1

COVER A

Fig.2

SELECT LOCATION

1. Do not install the unit in rooms where flammable gas or alkaline acid substances are present. Aluminum/copper coils and/or internal plastic components can be damaged irreparably.

2. Do not install in workshops or kitchens; oil vapors drawn in by treated air might deposit on the coils and alter their performance or damage the internal plastic parts of the unit.

3. Installation of the unit will be facilitated by using a stacker and inserting a plywood sheet between the unit and the elevated stacker.(Fig.2)

4. It is recommended to position the unit as centrally as possible in the room to ensure optimum air distribution. (Fig.3)

Generally the best louver position is the one which allows air diffusion along the ceiling. Alternatively intermediate positions can be selected.

5. Check that it is possible to remove panels from ceiling in the selected position, to allow enough clearance for maintenance and servicing operations.

INSTALLATION LOCATION

INSTALL THE UNIT IN A POSITION:

1. Having sufficient strength to carry the weight of the unit.

2. Where the inlet and outlet grilles are not obstructed and the conditioned air is able to blow all over the room.

3. From where condensate can be easily run to drain.

4. Check the distance between the upper slab and false ceiling to ensure the unit will suit the distance. See Fig.4

OPENING DIMENSIONS AND POSITIONS FOR SUSPENSION BOLTS

1. Mark position of suspension rods, water lines and condensate drain pipe, power supply cables and remote control cable.

2. Supporting rods can be fixed, depending on the type of ceiling, as shown in Fig.

7 and Fig.8.

3. Fit suspension brackets supplied with the unit to the threaded rods (Fig.9).

4. Do not tighten nuts and counter nuts; this operation has to be done only after final leveling of the unit, when all the connections have been completed.

Fig.7 Fig.8

PRELIMINARY CHECKS BEFORE START-UP

1. The unit should not be started up until the system piping has been cleaned and all the air has been purged.

2. Check condensate drain pipe slope.

3. After you have connected the main power supply to the cassette unit, it is necessary to check the good function of the condensate water pump which is installed inside.

Due to transport vibration, it might be possible that the float switch is hung up and the pump might not work in the correct way. For this reason, you have to do the following, to ensure good functioning of the unit: a. Install the cassette unit in an absolute horizontal position. b. Fill the internal drainpan (manually) with enough water to ensure the drain pump is working. c. You can fill the drainpan by pouring water through the external drainpan.

If everything is correct, the water will be pushed out into the pipe work you have installed. If the valve does not open, you have to make sure the float switch is not hung up inside the unit and you will have to loosen it by hand.

4. Make sure that air filter is clean and properly installed.

5. Ensure that voltage and current values correspond with the unit nameplate values; check electrical connections.

6. Verify that air outlets are not closed.

MAINTENANCE

1. Before performing any service or maintenance operations, turn off the main power switch.

2. The air filter is made of acrylic fiber and is washable in water. To remove filter simply open the intake grille by releasing the two catches. See Fig.19 and the section filter removal.

3. Check the filter periodically and before the operating season; clean or replace as necessary.
