12 - FACTORY OPTIONS AND ACCESSORIES
12.10 Cooling recovery circuit (CR and CT
assemblies)
Thermodynamic circuit dedicated to the recovery of the extracted
air energy, with independent and proportional control, adapted
to the air renewal requirements in order to raise the COP and
EER of the unit.
The circuit is composed of:
●
Return EC plug-fan.
●
Air circuit comprised of coils with copper pipes and aluminium
fi
ns.
●
Electronic expansion valve.
●
Hermetic scroll-type compressor assembled over antivibration
mounts.
●
Crankcase heater.
●
Four-way cycle reversing valve.
●
Anti-acid dehydrator
fi
lter.
●
High and low pressure transducers.
●
Condensates drain pan, with a 1/2” M gas threaded plastic
drain connection.
Access to the recovery circuit
The charging valve (schrader type)
must be used to adjust the refrigerant
charge of the recovery circuit when this
one is lower than required. It’s placed
on the liquid line before the dryer
fi
lter.
In models 0420 to 0720, the charging
valve can be accessed via the
compressors box on circuit 2, removing
the communication panel between both
circuits.
