General Chiller Maintenance

WARNING: Hazardous Voltage w/Capacitors!

Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.

Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing.

Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized.

NOTICE: Check Purge Run-Time for Unit Hermetic Integrity!

Failure to follow instructions below could result in chiller damage.

If frequent purging is required, monitor purge pumpout rate, and identify and correct source of air or water leak as soon as possible to prevent moisture contamination caused by leakage.

NOTICE: Do Not Use Non-Compatible Parts or Materials!

Use of non-compatible parts or materials could result in equipment damage.
