Installation - Mechanical

Close Up

After drywall is in place and rooms are prepared for final
wall treatment, the supply and return-air openings and
control compartment opening should be securely covered
to prevent introduction of foreign material. If the wall
texture and/or color are to be spray applied, it is imperative
that none of the over spray contact the coil, fan or other
unit parts.
NOTICE
Complete Enclosure Required!
Do not operate unit at any time without a complete
enclosure, supply grille, return-air panel, and filter in
place. Operation in any other condition could result in
motor overload or burnout, clogging of the coil surface,
motor ventilation openings, fan blades, or all of the
preceding. Warranties are void if paint or foreign
materials of any kind are present on coil, fan, piping,
wiring, or other internal components.
Before installation of the return air panel, the following
steps should be taken:
1. Rotate the fan wheel by hand to ensure that it is free
and does not rub the housing. Handling during
shipment may have caused the wheel to shift. Adjust if
necessary.
2. Verify that the service valves are open and that the
motorized control valve, if supplied, is set for
automatic operation, if of such type.
3. Vent all air from the coil and related piping.
4. Check the drain line to see that it is not clogged and that
it is properly secured and positioned in a downward
pitch.
5. If the unit is equipped with a circuit setter valve in the
return line, the proper flow through the coil should be
set at this time.

Supply Air Grille Installation

The grille is a snap-in fit into the collar on the unit. The
supply air grilles can be manually adjusted.

1. The louver return air panel will ship with fasteners
installed.
2. Hook the panel over the bottom collar of the fan coil
unit, rotate the panel upright so that it is against the
wall and turn the head of the fastener to the locked
position.
Note: This type of return air panel requires a 1-inch deep
collar on the front of the fan coil unit. Drywall must
be attached directly to the front of the unit when
using this panel.
