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.

4 - CONNECTIONS / ELECTRIC WIRING DIAGRAMS
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.
- 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
unit’s outlet. Max. height: 25 cm (figure 06).
• 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 tube must be held with supports (figure 07).
• Do not install air intakes (figure 08).
• The line must not have an upward slope near the outlet.
