All water coils must be protected from
freezing after initial lling with water.
Even if the system is drained, unit coils
may still hold enough water to cause
damage when exposed to temperatures
below freezing.
Refrigerant systems should be tested with dry nitrogen
rather than air to prevent the introduction of moisture
into the system. In the event that leaking or defective
components are discovered, the Sales Representative
must be notied BEFORE any repairs are attempted.
All leaks should be repaired before proceeding with
the installation.
After system integrity has been established the piping
should be insulated in accordance with the project
specications. ALL chilled water piping and valves or
refrigerant suction piping not located over drain pans
must be insulated to prevent damage from sweating.
This includes factory and eld piping inside the unit
cabinet.
The drain should always be connected and piped to an
acceptable disposal point. For proper moisture carry-
off, the drain piping should be sloped away from the
unit at least 1/8” per foot. A drain trap may be required
by local codes and it is strongly recommended for odor
containment.
RETURN AIR LOCATION
This unit is equipped with a eld reversible rear or
bottom ducted air return for plenum style units.
To change the return air location, remove the reversible
plenum box panel and the lter rack. Rotate both the
reversible panel and lter rack 180 degrees. Replace
the reversible panel in the old lter rack position and
fasten using the supplied screws. Fasten the lter rack to
the location where the reversible panel was and replace
the lter(s) as described above.
FAN REMOVAL

the (4) ¼-20 nuts from the fan deck and sliding the
