7.0 FAULT FINDING
The SuperChill unit should give trouble free operation, however should a problem
occur, the tables below should enable most faults to be identified with ease.
Fault finding should be carried out by a competent person and any replacement
parts used should be authorised Heatrae spare parts.
SYMPTOM
POSSIBLE CAUSE
ACTION
The compressor
will not start
1. No power to unit
1. Check the power supply is not faulty and is
swithced on
2. Thermostat set to the OFF or minimum
cooling position
2. Turn thermostat to ON and adjust to cooler
temperature
3. Thermostat fault
3. Replace thermostat
4. Wiring fault
4. Check all wireing connections are secure and
correctly made (refer to Wiring Diagram page 5)
5. Compressor fault
5. Replace compressor
Water is ice cold
but operates
excessively
1. Poor ventilation
1. Ensure the unit is 60-70mm from the wall and
ventillation slots are clean and unobstructed
2. The condensor fins are dirty or airflow
over condensor is imparied
2. Clean the condensor (see Section 6.2)
3. Thermostat set to maximum cooling
position
3. Adjust thermostat to a less cool temperature
4. Faulty thermostat
Replace thermostat
5. Thermostat sensing probe not inserted
into the cold water tank correctly
5. Ensure thermostat sensing probe is pushed
fully into pocket in tank
6. High ambient temperatire (>45°C)
6 . At high ambient temperatures it is normal for
the unit to work continuosly
Compressor
works
continuosly, but
water is not cold
1. Gas leak from the cooling system
1. The remaining gas must be emptied and the
leak must be sealed. The unit should then be
recharged with the correct quality of gas (refer
to Technical Data on page 2 or data plate on the
appliance) NOTE: This action must only be done
by a qualified person.
2. Faulty compressor
2. Replace compressor
3. Coooling fan does not work
3. Replace cooling fan
4. Water low in ice bank
4. Top-up or replace ice bank (see page 6)
Unit works
excessibely, but
water is not cold
enough
1. Cold reservoir is frequently exhausted
by heary usage
1. The units cold water output is beeing exceeded
(see Technical Data page 5), Consider a larger unit
or installing another nearby
Water is cold,
but unit is
excessibely noisy
1. Pipe vibration
1. Check that water pipes are not vibrating against
other parts of the unit, adjust their position if
necessary
NOTE: This unit contains a copressor and the fan so some noise will be normal when these
are in operation.
Poor water flow
1. Low water pressure
1. Ensure water pressure is a minimum of 1 bar
2. Water filter clogged
2. Check and , if necessary, change water filter
cartridge
3. Thermostat sensor not inserted into the
housing of the cold water tank causing water
in tank to freeze
3. Switch off unit and allow to thaw. Insert
thermostat sensor correctly into housing in
tank.
