SERVICING
Caution
DO NOT attempt to service the refrigeration equipment without isolating
the cabinet from the mains supply.
The condenser uses R-290 refrigerant, so read Appendix A before
proceeding.
Refrigeration
Equipment
The compressor,
condenser fan and
condensate disposal
system are mounted in
the base of the
cabinet, behind the
condenser radiator.
Unscrew the lower
back panel to gain
access.
Compressor
The compressor is hermetically sealed.
It is fitted with a dryer, an overtemperature probe.
No access ports are provided for pressure monitoring or charging with
refrigerant. Read Appendix A for servicing instructions.
Condensate
Disposal
The condensate disposal system consists of a water tray with two heating
elements. The elements have a positive temperature coefficient, reducing
power when there is no water present.
Access to
Condenser
Radiator and
Control Gear
To access the condenser radiator and
control gear, simply pull the louver panel
forward, to disengage the magnetic
catches.
It is vital that the pre-filter and radiator
are kept clean. If air flow is restricted,
refrigeration efficiency will be poor.
The radiator fins must be regularly cleaned, using compressed air. Do
this at least every six months, or more often if needed.
