Compressors with Electrical Failure (Motor Burnout)
Before proceeding with installation, read all instructions, verify that all the parts are included and check the nameplate to be
sure the voltage matches available utility power. Follow all local codes. Installation, service, and maintenance work must be
performed only by properly trained and qualified personnel and in accordance with applicable regulations and manufacturers’
specifications.
WARNING! Risk of electric shock. Can cause serious injury or death. The Liebert® iCOM™ microprocessor
does not isolate power from the unit, even in the Unit Off mode. Some internal components require and
receive power even during the Unit Off mode of the Liebert® iCOM™ control. Open all local and remote
electric power disconnect switches and verify with a voltmeter that power is Off before working on any
component of the system.
WARNING! Risk of over pressurization of the refrigeration system. Can cause explosive discharge of high
pressure refrigerant, loss of refrigerant, environmental pollution, equipment damage, injury, or death. This
unit contains fluids and gases under high pressure. Use extreme caution when charging the refrigerant
system. Do not pressurize the system higher than the design pressure marked on the unit's nameplate.
NOTE: Release of refrigerant to the atmosphere is harmful to the environment. Refrigerant must be recycled or
discarded in accordance with federal, state, and local regulations.
1. Attach suction and discharge gauges to access fittings.
2. Recover refrigerant using an approved recovery procedure and equipment. Use a filter drier when charging the
system with recovered refrigerant.
