Replacement Procedures
Service Manual
Evaporator
Fans
The refrigeration unit is fitted with two evaporator fans, attached to the
evaporator fan shroud on top of the unit. The fans can be replaced
individually and each fan has a push in plug for easy removal.
To replace an evaporator fan
Compressor
The compressor is located behind the RH unit side panel on the refrigeration
unit.
If the compressor is causing excessive noise check the mountings to ensure
there is no damage to the rubber or washers, nuts and screws.
Before replacing the compressor, check all plug connections and ensure the
compressor electrics are operating correctly (see below). The compressor
must be supplied with consistent voltage over 220 volts, ensure the voltage
does not drop at start-up. If the voltage does drop, ensure the unit has a
direct power supply (not from a multi-box or extension cord).
If replacing the compressor, ensure the system is clear and not
contaminated. If there is a burn-out, a suction burn-out filter drier should be
used until all contamination is removed (use only as specified by the filter
drier manufacturer).

Electrics
The compressor electrics box is fixed onto the side of the compressor.
To access the compressor electrics
1. Isolate the chiller from the power supply and remove the refrigeration unit
from the cabinet (see page 33).
2. Unplug the push-in plug from the fan motor.
3. The fan can now be removed from the unit assembly. When fitting the
replacement fan, ensure the push-in plug is securely plugged in, the
orientation is correct and that the fan assembly is fixed onto the evaporator
assembly with the four perimeter fixing screws.
1. Isolate the chiller from the power supply and remove the refrigeration unit
from the cabinet (see page 33).
2. Remove the RH unit side
panel.
3. The compressor can now be accessed for servicing. Access can be
improved by removing the LH unit side panel, and carefully raising and
supporting the evaporator tub.
1. Gain access to the compressor (see steps above).
2. Use a flat head screwdriver to ease the electrics cover from the electrics box.
