Prior to connection of condensing
water supply, verify water pressure is
less than maximum pressure shown
on unit nameplate. To prevent injury
or death due to instantaneous release
of high pressure water, relief valves
must be field supplied on system
Always use a pressure regulator,
valves and gauges 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.
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.
Door compartments containing
hazardous voltage or rotating parts
are equipped with door latches to
allow locks. Door latch are shipped
with nut and bolts requiring tooled
access. If you do not replace the
shipping hardware with a pad lock
always re-install the nut & bolt after
