3.1 - CHOOSING THE LOCATION
• This unit is designed to be installed in sheltered rooms (IP 20).
• Do not install the device in a room containing inflammable, alkaline, acidic, greasy or very damp air, nor in one
where water is liable to be projected. The components will be irremediably damaged.
• Choose the most central position in the room.
• Check that the ceiling is sufficiently sturdy to support the unit’s weight.
• In the position chosen, check that no obstacle will impede installation and maintenance (beam, insufficient
false ceiling height, fixed false ceiling panels, access impossible for maintenance, etc.).
• Provide an access for easy maintenance, namely for the valve (and electrical box for CWX 3-5 models).
• Provide for the water pipes, electric cables and the condensate discharge outlet.
• Air must be able to circulate freely around the unit.
Note : air diffusion will be less efficient if room height is greater than 3 meters.

CAW 3-4-5
• Use the drilling template provided (2) to determine
the position of the suspension rods (1).
• The template must be placed between 2 “T” rails of
the false ceiling.
• Install the suspension rods (not supplied).
• Place the side where the connections are located in
the most appropriate position.
• The “T” rail (3), located on the electrical box side,
must be temporarily removed.
• Put the unit in place and check that it is level.
• Adjust the distance between the unit and the false
ceiling (5) (max. 23 mm) by using the suspension rod nuts.
• Also check the distance between the suspension flange (6) and the ceiling (7) (min. 41 mm). A lesser
distance may create noise if the unit touches the ceiling.

• Use the drilling template provided (2) to determine
the position of the suspension rods (1) and the hole
to be made in the false ceiling (figure 01).
For the suspension rods, use dia. 8 or 10mm
threaded rod.
• Refer to the dimensions in the table opposite
(figure 02).
• Install the suspension rods (not supplied).
• The length of the suspension rods must be long
enough to have distance of more than 15 mm
between the bottom of the suspension rod and the
bottom of the unit (figure 01).
• Place the side where the connections are located
in the most appropriate position.
• Install the unit on the suspension rods using the
nuts and washers (figure 03).
• Check that the unit is level.
• Adjust the distance between the unit and the top
of the false ceiling (48 mm) using the nuts on the
suspension rods (figures 01 and 03).
• Remove the protective cardboard from the fan.

4.1 - HYDRAULIC CONNECTION
• 1/2” (CAW 3-4-5 MODELS) 3/4” (CAW 6-8-10 MODELS) female gas connections on the unit.
- Water inlet: lower connection.
GB
- Water outlet: upper connection.
• For cold water use, a control valve must be installed, otherwise there is a risk that the condensate tank may
overflow if the unit shuts down due to a thermostat disconnection or in case of condensate pump failure (for
valve installation, refer to the “Accessories” paragraph).
Important: Securely hold the unit’s connections with a wrench while tightening in order to avoid twisting
the tubes inside the unit.
• Carefully insulate the water inlet and outlet tubes as well as the elements installed on the network (shut-off
valves, ...).
Use material that is adapted to the installation conditions and water system.
• The unit is equipped with an air bleeder above the connections. Depending on the installations, other bleeders
may be required on the hydraulic network.
4.2 - CONDENSATE CONNECTION
CAW 3-4-5 MODELS
• Connect a rigid PVC pipe (4) with OD 18 mm, on the unit’s drain
connection (2) using a piece of flexible hose (2). Secure it with clamps
(3). (figure 05)
CAW 6-8-10 MODELS
• Connect the supplied flexible hose (2) to the unit’s drain fitting (1) and
secure it with the clamp (3) provided. Do not force the drain fitting.
• Connect a rigid PVC pipe (4) on the end of the hose (2) and secure it
with the clamp (3) provided.
Note : secure the clamps while ensuring that the screws are facing
upward (figure 05).
ALL MODELS
• Carefully insulate the hose with polyethylene foam.
• Be aware of the risk of freezing in false ceilings during the winter.
• If necessary, the condensate tube can be raised immediately after the

• Make sure that the drain line has a slight slope in the flow direction
and that it does not form a siphon (figure 06).

• The additional fan motor for the outside air intake is equipped with a separate electric power supply and can
be controlled by means of a two-pole On/off switch with an electrical protection device.
• To avoid operating and noise-related problems, the new air output should represent approximately 10% of the
total air output.
- Open the knock-out (18), secure a Ø70mm flange on the unit and connect the thermal insulated conduit.
- On the exterior, install a grille with filter to prevent drawing in dust and debris which could clog the unit’s

not the same size. Correctly present them in front of the
corresponding locking clips.
- Check the correct position of the facade frame in relation to
the false ceiling. Adjust the position of the internal unit, as
required.
- Secure the facade frame to the unit using the special screws and
washers (8) provided.
- Fit the grille (3) making sure that the filter (9) is correctly installed.

7 - STARTING
IMPORTANT
Before doing any work on the air conditioner, make sure it is switched off and put out of bounds.
Any work must be carried out by personnel qualified and authorised to work on this type of air conditioner.
7.1 - PRELIMINARY CHECKS
• Make sure:
- that the air handler is well fixed,
- that the power cables are well fixed to their connection terminals,
- that the electric cables are properly insulated from any pieces of sheet or metal parts which could damage
them,
- that the unit is connected to earth,
- that no tools or any other objects have been left in the unit,
- that the filter is correctly fitted,
- that the coil is clean,
- the hydraulic couplings are correctly tightened,
- that the condensate discharge outlet is correctly connected,
- that the condensate drain pan is clean,
- that the condensate discharge outlet pipes are securely fastened.
7.2 - SWITCH ON THE UNIT
• Using the isolation and protection device.
• Start the device using the control box.
• Check that the fan operates correctly at the three
ventilation speeds, without abnormal mechanical
noise.
• Check that all the connections are watertight.
• Check that the condensate pump operates correctly
by pouring a little water into the auxiliary drain pan
under the valve.
• Check that there is no water backflow when the
pump is stopped.
• Purge the cassette.
7.3 - FILLING THE HYDRAULIC CIRCUIT
WITH WATER
• If a control valve is assembled, make sure that it
operates correctly, activating it by using the remote
control.
7.4 - STARTING
• See Operation Instruction manual.
8 - MAINTENANCE
Before doing any work on the installation, make sure it is switched off and put out of bounds.
All operations must be carried out by personnel that are approved and qualified for this type of equipment.
GENERAL MAINTENANCE
All equipment must be properly maintained in order to provide optimum performance over time. Faulty maintenance
can result in the cancellation of the product guaranty. Depending on the products, maintenance operations consist
in the cleaning of filters (air, water), internal and external exchangers, casings, and the cleaning and protection
of condensate tanks. Treating odours and the disinfection of room surfaces and volumes also contributes to the
cleanliness of the air breathed by users.
IMPORTANT
GB
• Air filter:
- Clean at least once a month or more
frequently (see Operating instructions).
• Electric connections :
- Once a year, check that the electric wires
are well fastened to their terminals.
• Electric box :
- Dusting is recommended once a year.
• Condensate drainage system :
- This requires regular specific maintenance.
- The maintenance cycle is determined by
the conditions of operation (minimum operations
to be performed each time the installation
is restarted in cooling mode).
3742551181-I-TEC-CAW-GB.indd 213742551181-I-TEC-CAW-GB.indd 21 27/01/2015 13:55:3727/01/2015 13:55:37
- Clean the condensate recovery tray located under
the heat exchanger and check hoses/pipes.
- Clean with water containing 5% bleach.
WATER-LEVEL ALARM
The operation lamp flashes and the air conditioner
simultaneously stops during exceeding condensate
drainage or because of malfunctioning of the
condensate drainage system (due to a faulty pump,
a dirty tank, or a plugged drain line,...).
