CAUTION
If a lifting device is used to move a unit, ensure
it is capable of supporting the weight of the unit.
Certain maintenance or cleaning procedures may
call for the use and handling of chemicals, solvents,
or cleansers. Always refer to the manufacturer’s
Material Safety Data Sheet (MSDS) prior to using
these materials. Clean parts in a well-ventilated area.
Avoid inhalation of solvent fumes and prolonged
exposure of skin to cleaning solvents. Wash exposed
skin thoroughly after contact with solvents.
CAUTION
Do not use cleaning solvents near open fl ame
or excessive heat. Wear eye protection when
blowing solvent from parts. The pressure-wash
should not exceed 30 psig. Solvent solutions
should be disposed of in accordance with local
and state regulatory statutes.
CAUTION
Chilled water cooling coils and associated
piping circuits are
pressurized (up to 100 psi)
and sealed when they leave the factory. Before
hooking up the interconnecting piping, observe
appropriate safety precautions and release
the pressure via an available stem valve or
schrader valve prior to uncapping the pipes.
CAUTION
After the customer furnished supply and return
piping is assembled, the piping system must be
thoroughly cleaned prior to connecting it to the
unit. Failure to do so will result in equipment
problems.
CAUTION
After the supply and return piping is connected
to the unit, the entire system must be fl ushed
prior to beginning operation.
CAUTION
When installing and fi lling the water/glycol loop,
all air must be bled from the piping system.
WARNING
Do not use chloride based water conditioning
additives in the condensate drain pans. This
will cause corrosion to occur on the coil fi ns.
