4 - CONNECTIONS

4.1 - HYDRAULIC CONNECTIONS
• 1/2" 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 overfl ow 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
• Connect a rigid PVC pipe (8) with OD 18mm, on the unit's drain connection (12) using a piece of fl exible hose (9). Secure it
with hose clamps (10).
• Carefully insulate the hose with polyethylene foam (11).
• 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 (13).
• The tube must be held with supports
(14).
• Do not install air intakes (15).
• Do not install the tube with a slope (16).
There is a risk that water may fl ow back
when the unit is off.

4.3 - FRESH AIR CONNECTION
• The unit can be connected to an outside air inlet conduit (17).
• 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 fl ange on the unit and connect the thermal insulated conduit.
- On the exterior, install a grille with fi lter to prevent drawing in dust and debris which could clog the unit's exchanger.
