8.2.1 The Refrigerant Compressor
The refrigerant compressor fitted to the dehumidifier is a durable unit that
should give many years of service. However, loss of refrigerant may result in
compressor failure.
If the level of the refrigerant is low, contact the factory Service Center to
report the issue. Then, contact a local refrigeration technician to fill the unit
with the appropriate refrigerant (see tables in Appendix A).
Any professional refrigeration technician will be able to service the
equipment. The following procedure must be used:
1.
Turn the unit off.
2. Find the source of the leak.
Note
For evacuating and recharging the unit, use the crimped and brazed
charging stub attached to the side of the refrigerant compressor.
3.
Evacuate the unit from the remaining refrigerant before recharging.
4. Fix the leak.
5. Vacuum the unit pipes using a vacuum pump.
6. Recharge the unit with accurately measured by weight refrigerant.
Note
NEVER allow permanent service valves to be fitted to any part of the
refrigerating circuit. Service valves may leak, causing further loss of
refrigerant.
To check for failure of the compressor:
This check should only be performed by a certified refrigeration technician.
In the case of a compressor failure, the compressor can be replaced by a
certified refrigeration technician.
