1. Should an electrical component fail, consult the Factory Service Center to
obtain the proper 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 allow permanent service valves to be fitted to any part of the
EVER
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.
