AIR CONDITIONER INSTALLATION
Unpacking the Unit
It is recommended that the unit be unpacked at the installation
site to minimize damage due to handling.
CAUTION:
Do not tip the unit on its side. Oil may enter the
compressor and cause damage.
1. Remove the bands from around the unit.
2. Unfold the top and bottom cap flanges.
3. Carefully remove the top cap and tube.
Installing Return & Supply Air Collars (Optional)
Supply and return collars are not supplied with the unit but
are offered as accessory item. Check with your distributor for
pricing and availability. They can be easily positioned over the
unit openings and secured with sheet metal screws. See
&
.
• The diameter of the return duct collar is 14”.
• The diameter of the supply duct collar is 12”.
• Before permanently installing the collars, it is recommended
you pre-fit them over the openings first to determine best fit
and alignment.
Supply Duct
1. Assemble the collar by overlapping the two ends.
NOTE:
One end of the collar is slotted and the opposite end
has two small holes. Position the end with small screw holes
underneath the slotted end.
2. Fasten the collar ends with two self drilling sheet metal screws.
3. Position the collar over the opening and align the 4 holes in
the collar with the 4 holes (or dimples depending on model)
in the rear panel.
4. Using self-drilling screws (10-16x.5), secure the collar to the
rear panel.
Return Duct
1. Assemble the collar by overlapping the two ends.
NOTE:
One end of the collar is slotted and the opposite end
has two small holes. Position the end with small screw holes
underneath the slotted end.
2. Fasten the collar ends with two self drilling sheet metal screws.
3. Position the collar over the opening. Align the four holes in
the collar with the four dimples or holes (depending on unit
model) in the panel.
4. Secure the collar to the rear panel using self tapping screws
(10-16x.5).
Locating & Installing the Return Air Assembly
To simplify installation, locate and install the return air assembly
first. If desired, the return opening can be located inside a closet
with louvered doors that has an open area equal to or greater
than a 12” x 20” grille. The return air grille can be placed in the
wall of a closet and the air ducted into the filter box through a
boxed-in area at the closet floor level (
Verify the filter
is readily accessible.
NOTE:
The return air box with grille and filter should not be
located in heavy traffic areas like hallways or center of rooms.
A good spot is in a corner or under a table, if a minimum two
inch clearance is available.
1. Start the installation from under the home by cutting a small
hole in the subfloor. Determine how the floor joist location
will affect cutting the opening needed for the return air box.
NOTE:
Floor joists are generally located on 16” centers,
leaving 14-3/8” between joists.
2. After measuring the return air box (approximately 12-1/4” x
20-1/4”), cut the hole through the floor so that the box will fit
between the floor joists. Care should be taken when cutting
through carpeting to avoid snags.
NOTE:
In most installations
it will be necessary to cut a similar hole in the fiberboard
directly under the hole in the floor. However, if the floor is
more than ten inches deep, it will only be necessary to cut
a hole for the collar on the return air box or for the insulated
duct.
3. Set the box into the opening and fasten with screws or nails.
4. Install the filter and return air grille in the air box.
Connecting the Return & Supply Air Flexible Ducts
• Flexible ducts may be cut to the required length and spliced
with sheet metal sleeves and clamps.
Keep all ducts as short
and straight as possible. Avoid sharp bends.
Please follow
all instructions packed with duct.
• Flexible ducts can be secured to the corresponding fittings
with the clamps provided with the ducts.
NOTE:
To prevent a
loss in cooling capacity, make sure all connections are tight.
• Ducts may be spliced with sheet metal sleeves and clamps.
• After the inner duct is connected to the proper fitting, the
insulation and plastic sleeve should be pulled over the
connection and clamped.
• Homes with multiple supply ducts (or special applications),
a Y fitting is available to divide the supply air so it can be
ducted to different areas of the home for more efficient cooling.
NOTE:
For maximum performance, insulate the Y fitting.
