Periodic Maintenance
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 qualifi ed 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 fi lter. Refer to “Maintenance Procedures “.
• Contact a qualifi ed service organization to leak check the chiller, to inspect safety controls, and inspect electrical
components for defi ciencies.
• 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 qualifi ed service organization to determine when to conduct a complete
examination of the unit to determine the condition of the compressor and internal components.
