WATER FREEZING
Failure of the condenser due to
freezing will allow water to enter the
refrigerant circuit and will cause
extensive damage to the refrigerant
circuit components. Any damage to
the equipment as a result of water
freezing in the condenser is excluded
from
coverage under AAON
warranties and the heat exchanger
manufacturer warranties.
Do not clean DX refrigerant coils with
hot water or steam. The use of hot
water or steam on refrigerant coils
will cause high pressure inside the
coil tubing and damage to the coil.
CAUTION
Door compartments containing
hazardous voltage or rotating parts
are equipped with door latches to
allow locks. Door latch are shipped

closing the door.
CAUTION
Cleaning the cooling tower or
condenser water loop with harsh
chemicals such as hydrochloric acid
(muriatic acid), chlorine or other
chlorides,
can damage the
refrigerant-to-water heat exchanger.
