SAFETY PRECAUTIONS
To avoid physical injury, use caution when cleaning or
servicing the air conditioner.
Water source units are shipped with a factory refrigerant
charge and service valves closed. Do not open service valves
on water source units until all non-condensable foreign sub-
stances are removed from the piping system and authorization
to open valves is obtained from the LG-authorized
commissioning agent. Do not run compressors with the
service valves closed.
There is a risk of equipment damage, refrigerant contamination,
refrigerant loss, physical injury or death.
Do not use this equipment in mission critical or special-
purpose applications such as preserving foods, works of art,
wine coolers or refrigeration. The equipment is designed to
provide comfort cooling and heating only.
Oil, steam, sulfuric smoke, etc., can significantly reduce the performance
of the unit, or damage its parts.
Do not turn off the main power switch after operation has
been stopped.
Wait at least five (5) minutes before turning off the main power
switch, otherwise it may result in product malfunction.
Provide power to the compressor crankcase heaters at least
six (6) hours before operation begins.
Starting operation with a cold compressor sump(s) may result in se-
vere bearing damage to the compressor(s). Keep the power switch
on during the operational season.
Clean up the site after servicing is finished, and check that
no metal scraps, screws, or bits of wiring have been left
inside or surrounding the unit.
