Maintenance and Troubleshooting
NOTICE!
Risk of improper maintenance. Can cause equipment damage.
All maintenance must be performed only by authorized properly trained and qualified personnel.
Ignoring safety instructions is dangerous. Soiled parts cause a loss of performance and, for switch or control
devices, can lead to the breakdown of the unit performance and operation.
NOTICE!
Risk of release of hazardous substances into the environment. Can cause environmental pollution and
violation of environmental regulations.
The Liebert® CRV contains substances and components hazardous for the environment (electronic
components, refrigerating gases and oils). At the end of its useful life, the Liebert® CRV must be dismantled by
specialized refrigerating technicians. The unit must be delivered to suitable centers specializing in the
collection and disposal of equipment containing hazardous substances.
3.1
Maintenance
3.1.1
Refrigeration System
1.
Check that the refrigeration pipes are firmly fixed. The refrigeration pipes shall not shake with the vibration of wall,
earth or equipment frame. Otherwise reinforce the refrigeration pipes with fastening objects.
2.
Check that there is no oil on the accessories of all refrigeration pipes, and make sure that the pipes do not leak.
3.1.2
Heat Exchanger
1.
Clean the fin of heat exchanger regularly.
2.
The best overall condenser coil cleaner to use is plain water or compressed air. If the coil has been maintained and
cleaned at regular intervals, water or compressed air is sufficient to remove dirt and debris from the fins. Heavy
build up on the exterior of the fins can be removed with a brush. Water pressure from a garden hose and sprayer
usually works well. If the installation environment of the condenser does not allow the fins to be cleaned with
water, the compressed air may be a better method. The recommended pressure for the air is about 0.3Mpa.
3.
Check for damaged or bent fins and straighten them as needed.
4.
Avoid snow accumulation around the condenser in winter.
3.1.3
Fan
Check that the fan runs normally and check it for problems such as abnormal noise, vibration and bearing failure.
