manufacturer’s warranties.
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.
Care should be taken to avoid
allowing chemicals to enter the

Door compartments containing
hazardous voltage or rotating parts
are equipped wit
allow locks. Door latch are shipped
with nut and
access.
If you do not replace the
shipping hardware with a pad lock
always re-install the nut & bolt after
closing the door.
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.
Some chemical coil cleaning
compounds are caustic or toxic. Use
these substances only in accordance
with the manufacturer’s usage
instructions.
instructions may result in equipment
damage, injury or death.
To prevent damage to the unit, do not
use acidic chemical coil cleaners. Do
not use alkaline chemical coil
cleaners with a pH value greater than
8.5, after mixing, without first using
an aluminum corrosion inhibitor in the
cleaning solution.
Always use a pressure regulator,
valves and gau
ges to control
incoming pressures when pressure
testing a system. Excessive pressure
may cause line ruptures, equipment
damage or an explosion which may
result in injury or death.
