Do not work in an enclosed area
where refrigerant or nitrogen gases
may be leaking. A sufficient quantity of
vapors may be present and cause
injury or death.
Polyolester (POE) and Polyvinylether
(PVE) oils are two types of lubricants
used in hydrofluorocarbon (HFC)
refrigeration systems. Refer to the
compressor label for the proper
compressor lubricant type.
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.
Some chemical coil cleaning
compounds are caustic or toxic. Use
these substances only in accordance
with the manufacturer’s usage
instructions. Failure to follow
instructions may result in equipment
damage, injury or death.
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.
Factory installed convenience outlets
are not intended for use while the unit
is operating.
