INFORMATION
Field supplied water piping must include
a pet cock or other suitable means at the
highest point to bleed air from the water
piping�
INFORMATION
High inlet water temperature or low water
flow rate may result in nuisance tripping of
the refrigerant high pressure switch�
INFORMATION
Water-cooled units with a glycol cooling
fluid will require a higher GPM / Ton flow
rate�
Contact the factory for details�
INFORMATION
Water-cooled units have been designed
for use with fresh water application only�
Do not use for brackish water or salt water
unless appropriate condenser and water
piping has been applied�
INFORMATION
Units have been tested at the factory
before shipment. The test fluid at the
factory contains a glycol mixture� It is
important to flush the internal unit piping
and heat exchangers at the job site prior to
start-up or connection to the cooling fluid
circuit being used�

The water piping that is installed internal to the modules in
the field will need to be wrapped to minimize any condensate
forming on the piping� The same gasket material used to seal
between the module sections can be used to accomplish
this�
Dual modules include factory applied insulation between the
module sections to seal air leakage where the water piping
passes through the cabinets that might occur between the
two modules�
ELECTRICAL HAZARD
Only a qualified licensed electrician or
other individual that is properly trained in
handling live electrical components should
perform the wiring installation� Failure to
follow all electrical safety precautions and
industry accepted practices when exposed
to live electrical components could result
in death or serious injury�
INFORMATION
Use Copper Conductors Only� Failure
to use copper conductors may result in
equipment damage�
INFORMATION
All electrical wiring must be in accordance
with NEC (National Electrical Code), NFPA
(National Fire Protection Agency) most
current versions as well as any applicable
state or local codes�
