A Connect the drain pipe
● Water condensation must be evacuated directly to the outside; observe an appropriate slope for the evacuation duct, which should slopedownwards the
case of a connection to the wastewater system (2.5 cm/m slope).
● An S-bend must be installed on the evacuation duct, below the level of the recovery tray of the unit.
● Provide insulation for the evacuation piping in the case of a risk of freezing or condensation.
● Evacuation with pump kit: (refer to instructions provided with kit).
a.The unit is supplied with an evacuation piping.
b.The right and left outlets are blocked off by a plug. Do not forget to remove this plug before connecting the evacuation piping.
● In the case of a ceiling mounted installation, run the evacuation piping down along the side panel and secure it with clamps as shown below. Also break
the preformed cut-out in the coner of the intake grid.
