REPAIRS
1.
Should an electrical component fail, consult the Factory Service Center to obtain the
correct
replacement
part.
2.
If refrigerant gas is lost from the machine, it will be necessary to use a refrigeration
technician to correct the fault. Contact the Factory Service Center prior to initiating
this
action.
Any competent refrigeration technician will be able to service the equipment. The
following procedure must be used:
a. The source of the leak must be determined and corrected.
b. The machine should be thoroughly evacuated before recharging.
c. The unit must be recharged with refrigerant measured accurately by weight.
d. For evacuation and recharging of the machine, use the crimped and brazed
charging stub attached to the side of the refrigerant compressor.
The charging stub should be crimped and rebrazed after servicing.
N
EVER
allow
permanent service valves to be fitted to any part of the circuit. Service valves
may leak causing further loss of refrigerant gas.
3. The refrigerant compressor fitted to the dehumidifier is a durable unit that should
give many years of service. Compressor failure can result from the machine losing its
refrigerant gas. The compressor can be replaced by a competent refrigeration
technician.
Failure of the compressor can be confirmed by the following procedure:
a. Establish that power is present at the compressor terminals using a voltmeter.
b. With the power disconnected, check the continuity of the internal winding by
using meter across the compressor terminals. An open circuit indicates that the
compressor should be replaced.
c. Check that the compressor is not grounded by establishing that a circuit does not
exist between the compressor terminals and the shell of the compressor.
