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.
Fan coils must be installed by an authorized company only.
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 required for technical maintenance operations.
• It is advisable to place the unit close to the installation site without removing it from the packaging.
Do not put heavy tools or weights on the packaging.
• 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.
• Check immediately for installation accessories inside the packaging.
• Do not lift unit by the condensate drain discharge pipe or by the water connections; lift it by the four corners.
• Check and note the unit serial number.

• 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.
• 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.
•
Installation of the unit should be facilitated by using a stacker and
inserting a plywood sheet between the unit and the elevated
stacker.(Fig.1)
• It is recommended to position the unit as centrally as possible in
the room to ensure optimum air distribution.
Generally the best louver position is the one which allows air
diffusion along the ceiling.
Alternatively intermediate positions can be selected.
• Check that it is possible to remove panels from ceiling in the
selected position, to allow enough clearance for maintenance and
servicing operations.
Install the unit in a position:
• Having sufficient strength to carry the weight of the
unit.
•
Where the inlet and outlet grilles are not obstructed
and the conditioned air is able to blow all over the
room.
• From where condensate can be easily run to drain.
• Check the distance between the upper slab and
false ceiling to ensure the unit will suit the distance.
See Fig.2. (Distance A 290 mm; distance B 10 mm

• Mark position of suspension rods, water lines and condensate drain pipe, power supply cables and
remote control cable.
Supporting rods can be fixed, depending on the type of ceiling, as shown in Fig. 5 and Fig.6.
• Fit suspension brackets supplied with the unit to the threaded rods (Fig.7).
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.

• The spaces between the unit and ceiling can now be adjusted. Use the drop rods to make the adjustment.
• Check to ensure the unit is level. The drain will then automatically be lower than the rest of the drip tray.
• Tighten the nuts on the suspended rods.
Fig.7
• Ensure the ceiling is horizontally level,
otherwise condensate water cannot drain.
•
The casing is fixed to the slab with 4 drop rods.
The rods should have two nuts and washers to
lock the unit in position. The Cassette brackets
will then hook over the washers.
• When lifting the Cassette into position care
should be taken not to lift the unit by the drip
tray, which could be damaged.
• Lift unit (without the air panel) with care by its
four corners only. Do not lift unit by the
condensate drain discharge pipe or by the
piping connections.
• Incline unit (Fig.8, Fig.9) and insert it into the
false ceiling. Insert the rods into the bracket
slot.
With minimum height (see table) false ceilings,
it might be necessary to remove some T
brackets of the false ceiling temporarily.
• Using a
level guide, line up the unit with a spirit
level, and keep dimension between the body
and the lower part of the false ceiling (Fig.10).
• Line up the unit to the supporting bars of the
false ceiling tightening the nuts and counter
nuts of the threaded rods.
•
After connection of the condensate drain piping
and piping connections, check again that the
unit is level

When the installation is completed, it is necessary to wrap connecting pipe with insulation to prevent leakage to
ceiling tile.
INTER CONNECTING WIRING
We recommend that screened cable be used in electrically noisy areas.
1. Always separate low voltage (5VDC) signal wires from power line (230 VAC) to avoid electro-magnetic
disturbance of control system.
2. Do not install the unit where electromagnetic waves are directly radiated at the infrared receiver on the
unit.
3. Install the unit and components as far away as is practical (at least 5 meters) from the electromagnetic
wave source.
4. Where electromagnetic waves exist use shielded sensor cable.
5. Install a noise filter if any harmful noise exists in the power supply.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified
person in order to avoid a hazard.
