avoid the formation of condensation, which could drip onto suspended ceilings

causing considerable problems.

The water connections are fixed to the unit body to avoid damage when pipes are

connected. It is advisable to tighten the connection with a wrench. The upper coil connection

is fitted with an air valve and the lower connection with a drain valve, suitable for a 10 mm

wrench or screwdriver. (The coil is only partially drainable; it is advisable to blow air into

the coil for complete drainage)

INSTALLATION OF AUXILIARY DRAIN PAN

Remove the plastic cap from the condensate drain outlet on the water cassette. Do

NOT push the cap into the cassette. Fit the nozzle into the hole (auxiliary condensate

drain pan outlet).

Fix the auxiliary drain pan to the unit using the relative screws provided in the kit,

ensuring that the condensate pan is level

IMPORTANT! If the drain pan plastic cap is removed, remember to seal it

with silicone when replacing it!

CONDENSATE DRAINAGE

ATTENTION!

CONDENSATE DRAINAGE IS FUNDAMENTAL FOR GOOD OPERATION OF THE

WATER CASSETTE. LAG THE PIPES SUITABLY AND CORRECTLY.

To ensure a correct flow of the condensed water, the water drainage pipe must have a

slope of 2% without obstructions. Install a trap at least 50 mm deep in order to avoid

unpleasant smells.

There is the possibility of draining water from 200 mm above the level of the unit. To drain

the condensate at a higher level, install condensate drain pump with collecting tray and

float valve. A float valve is recommended to stop the flow of water in the event of pump

failure.

A few examples are shown schematically below of condensate drainage connection in

a correct (fig. 20-21) and incorrect manner (fig. 22-23).

INSTALLATION, USE AND

MAINTENANCE GUIDE

Fig. 20: When several units are installed near to each other and only one

condensate drain hose is used, make sure that the capacity of the hose is

sufficient and that it is positioned on a slightly lower level than the appliance.

Fig. 21: The condensate drain hose should be fixed using intermediate mounts

to prevent deformation of the hose. The drain hose should slope slightly

downwards to encourage drainage of the condensed water.

Fig. 22: The drain hose is bent or points upwards.
