•
Y ‐ shaped metallic filter (to be mounted on the inlet pipe) with a mesh not larger than 1 mm.

Unit water inlet pipe have to be in correspondence with the connection labelled: ”WATER INLET”, otherwise the
evaporator may freeze.
It is compulsory to install on the WATER INLET connection a metallic filter with a mesh not larger than 1 mm.
Should the water flow switch be altered or should the filter not be installed, the warranty will no longer be valid.
The filter have to be kept clean, so make sure it is clean after the unit has been installed, and then check it
periodically.

All units are standard supplied with the water flow switch (factory installed). The water flow switch HAS TO BE
INSTALLED on the water outlet connection (labelled WATER OUTLET). Should the water flow switch be altered,
removed, or should the water filter not be installed on the unit, the warranty will be invalidated. Please refer to
the wiring diagram for the water flow switch electric connections.
