4.4 Ventilation
- Axial flow, low speed helical fans on condensing
unit (GC).
- Soundproof motors equiped with built-in heat safety
device.

4.5 Electric heating

Cooling only and Heatpump indoor units may be
equipped with an electric heating coil. They are outfitted
with a temperature limiter. For heatpump models
simultaneous operation with thermodynamic heating
is possible.
4.6 Thermodynamic heating
Heatpump models are equipped with cycle reversing
cooling system allowing to operate in thermodynamic
heating by means of an AIR/AIR heatpump down to
an outdoor temperature of –7°C.
Calories are transferred from the outside to the room
to be heated with an excellent coefficient of perfor-
mance (COP).
5. MAINTENANCE

Procedures for working on the cooling cir-
cuit, and the technical charac-teristics, are
different from the R22.
Consult the corresponding instructions and
follow the recommendations when carrying
out any work.
