All water coils must be protected from
freezing after initial filling 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 notified 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
specifications. 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 field 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 field 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 filter rack. Rotate both the
reversible panel and filter rack 180 degrees. Replace
the reversible panel in the old filter rack position and
fasten using the supplied screws. Fasten the filter rack to
the location where the reversible panel was and replace
the filter(s) as described above.
FAN REMOVAL
This fan assembly is easily removable by unscrewing
the (4) ¼-20 nuts from the fan deck and sliding the
fan assembly off of the weld studs. Disconnect motor
wiring. Reassemble fans and torque nuts to 30 in/lbs.
PLENUM BOX SERVICE PANEL
The service panel on the plenum box is easily removable
by removing the screws located on the sides and bottom
of the service panel.
