Annual Maintenance
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.
• Shut down the chiller once each year to check the
following:
• Perform all weekly and monthly maintenance
procedures.
• Check the refrigerant charge and oil level. Refer to
“Maintenance Procedures “. Routine oil changing is not
necessary on a hermetic system.
• Have a qualified laboratory perform an oil analysis to
determine system moisture content and acid level.
IMPORTANT NOTE: Due to the hygroscopic properties
of the POE oil, all oil must be stored in metal containers.
The oil will absorb water if stored in a plastic container.
• Check the pressure drop across the oil filter. Refer to
“Maintenance Procedures “.
• Contact a qualified service organization to leak check
the chiller, to inspect safety controls, and inspect
electrical components for deficiencies.
• Inspect all piping components for leakage and/or
damage. Clean out any inline strainers.
• Clean and repaint any areas that show signs of
corrosion.
• Test vent piping of all relief valves for presence of
refrigerant to detect improperly sealed relief valves.
Replace any leaking relief valve.
• Inspect the condenser tubes for fouling; clean if
necessary. Refer to “Maintenance Procedures “.
• Check to make sure that the crank case heater is
working.
Scheduling Other Maintenance
Depending on chiller duty, contact a qualified service
organization to determine when to conduct a complete
examination of the unit to determine the condition of the
compressor and internal components.
