3 - COOLING LINKING PIPES
The two indoor and outdoor units are equipped with
flare couplings allowing to use flare cooling pipes
(copper pipes of cooling quality equipped at their ends
with nuts).
4 - DESCRIPTION
4.1. Casing
- Panels and insulated sheet metal for the indoor unit
are treated for protection against corrosion with
powder paint or oven-baked enamel according to
model of the outdoor unit.
- Combined blower/intake grille, for the Cassette.
- Possible hand operated adjustment of air distribu-
tion on all four sides. Possibility to close one or two
faces of discharge.
- Intake at center with filter.
- Prepunched holes for connection with fresh air intake
and connection with a stud duct to treat an adjacent
room. In that case it becomes necessary to provide
a decompression in the adjacent room (grille ...) to
allow air intake on the Cassette.
4.2. Insulation
- Heat and sound insulation throughout the indoor air
treatment unit.
- The whole compressor compartment of the conden-
sation unit is soundproofed (except models GC 45FA/
RCFA).
4.3. Cooling circuit
- Hermetic compressor group equipped with thermic
and electrical protections connected wiht a entirely
brazed, sealed cooling circuit.
- “Capillary” type foolproof expansion element.
- Cooling filter built into the cooling circuit.
- "AROUND THE YEAR" system (accessory), regulating
the high pressure of the cooling circuit in order to
operate when cooling, down to an outdoor
temperature of –10°C by ventilation speed variation
of the outdoor unit.
- Cycle reversing valve for heatpump heating.
- Heatpump models, nonreturn and additional expan-
sion valve, through capillary tube or by restricters for
the K 45FA and K 45CEFA (restricters supplied in
kit form in the GC 45RCFA).
4.4. Ventilation
- Ventilation of helicoid type profiled for axial flow and
low rotation speed for the Condensing Unit.
- For the air treatment unit : centrifugal fan with direct
drive.
- Motors mounted on rubbers and equipped with
internal thermal safety devices. 3-speed motor for
the air treatment unit.
4.5. Filtration
Cleanable air filter accessible after opening the
discharge/intake combined grille.
