Check the unit Installation, Operation, and Maintenance
manual (see “Literature Referenced,” p. 6) for specific
instructions.
Operating conditions must always remain within the
operating range
of the compressor. This includes:
• Operating pressures (suction and discharge pressure).
• Operating temperatures (suction, discharge, and
liquid).
• Operating parameters (compressor superheat,
subcooling,
oil
sump superheat, voltage, and
amperage).
• Check all of the following on a regular basis:
– System operating conditions.
– System refrigerant charge level.
– Oil levels and oil color.
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
• Check electrical connections (prior to startup each
season).
