1.4.1 ARC Models: air conditioning
The ARC model circulates refrigerant gas (R-410A) through a cooling circuit driven by two compressors
mounted in tandem. The propelled gas circulates through an evaporator coil where it absorbs ambient
heat and evaporates. To liquefy the evaporated gas, it is then circulated through a condenser coil where
it releases the previously absorbed heat into the atmosphere.
To favour the evaporation and condensation of the gas refrigerant, the unit has supply and intake fans
that force the air through each of the coils. In the case of the evaporator, the fan pushes air to the inside
of the building or property through previously-installed distribution ducts. In the case of the condenser,
the fan pushes fresh air through the coil and then sends it back outdoors.
A series of filters remove dust particles and pollen, etc. from the air sent inside the building or property.
1.4.2 ARG/ARD Models: cooling / heat pump, gas burner heating
The ARG/ARD models join an additional heating and air supply system to their respective cooling circuits.
In this case, the air inbound to the building or property circulates in a chamber where a tube exchanger
is located. High temperature from the gas burner circulates inside the pipes.
1.4.3 ARG/ARD Models: cooling / heat pump, gas burner heating
The ARG/ARD models join an additional heating and air supply system to their respective cooling circuits.
In this case, the air inbound to the building or property circulates in a chamber where a tube exchanger
is located. High temperature from the gas burner circulates inside the pipes.
1.4.4 General instructions
C A U T I O N
• Always keep the electrical power supply connected to the unit.
• Only disconnect the unit if it is not to be used for a long period of time.
• When preparing for seasonal use, connect the unit to the electricity supply at least 8 hours before
starting it.
Connect the air conditioning unit to the electricity sup‐
ply at least 8 hours before starting it. To do so, use
the general switch -Q3-.
