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 3% without obstructions. Install a trap at least 50 mm deep in
order to avoid unpleasant smells.
3%
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 (not included in the standard accessories). A float
valve is recommended to stop the flow of water in the event of pump failure.

Pic. 17: when several units are installed near to each other and only one con-
densate drain hose is used, make sure that the capacity of the hose is sufficient
and that it is positioned on a sSOFTly lower level than the appliance.
3%
Pic. 18: the condensate drain hose should be fixed using intermediate mounts
to prevent deformation of the hose. The drain hose should slope sSOFTly down-
wards to encourage drainage of the condensed water.
Pic. 19: the drain hose is bent or points upwards.
Vers. 2015-3
Pic. 20: the drain hose is on the same lever as unit.
ATTENTION!
- Ultimately verify the smooth flow of condensate water from the basin to
the discharge pipe (before blocking the dropped ceiling)!
- If the condensate drainage alarm is activated, the zone valve is closed
and the fan turned off.

ELECTRICAL CONNECTIONS
< 100 mm
Pic. 16
CORRECT!
The electrical connections must be carried always on the terminal board (see
Pic. 21a)
Pic. 17
CORRECT!
ATTENTION!
Before carrying out electrical connections, ensure that the electricity
supply has been cut off, checking that the on-off switch is in the OFF
position.
Pic. 18
Only qualified electricians should carry out the electrical connections. Check
that the mains supply is single-phase 230 Vac/1/50 Hz (± 10%). Operating the
appliance with voltages outside the above limits could cause malfunction and
renders the warranty null and void.
The fan coil power supply line should be fitted with at least a switch isolator in
WRONG!
conformity with European standard EN60947-3. Make sure that the electrical
system is suitable for providing not only the working current required by the
appliance, but also the necessary current for powering household and other
electrical appliances already in use. Any electrical and mechanical alterations
or tampering render the warranty null and void.
The motor and accessories power cables in channels or conduits should remain

inside the same until they are inside the appliances.
