For Medium (15-18.5K) + Heavy duty (22-28.5K) Air Conditioner

READ BEFORE INSTALLING UNIT

To avoid risk of personal injury, property damage, or product damage due to the weight of this device and sharp
edges that may be exposed:

Air conditioners covered in this manual pose an excessive weight hazard. Two or more people are needed to

move and install the unit. To prevent injury or strain, use proper lifting and carrying techniques when moving unit.
Carefully inspect location where air conditioner will be installed. Be sure it will support the weight of the unit over
an extended period of time.

Handle air conditioner with care. Wear protective gloves whenever lifting or carrying the unit. AVOID the sharp
metal fins of front and rear coils.

Make sure air conditioner does not fall during installation.
If a new electrical outlet is required, have the outlet installed by a qualified electrician before installing unit.

NOTE: DO NOT USE ANY SCREWS OTHER THAN THOSE SPECIFIED HERE.

Preliminary instructions:

Do the following before starting to install unit. See illustrations below.
Check dimensions of your unit to determine model type:

Heavy duty Medium

Capacity: 22,000-28,500 BTU 15,000-18,500 BTU

Unit Height: 18-5/8" 17-5/8"
Unit Width: 26-1/2" 23-5/8"

1. Check window opening size: the mounting parts

furnished with this air conditioner are made to install in

a wooden sill double-hung window. The standard parts
are for window dimensions listed above. Open sash to
a minimum of 19" (483mm). (FIG.l)

2. Check condition of window: all wood parts of window
must be in good shape and able to firmly hold the needed
screws. If not, make repairs before installing unit.

3. Check your storm windows: If your storm window

frame does not allow the clearance required, correct by

adding a piece of wood as shown (FIG.2), or by removing
storm window while room air conditioner is being installed.

4. Check for anything that could block airflow
Check area outside of window for things such as shrubs, trees, or awnings. Inside, be sure furniture, drapes, or blinds

will not stop proper air flow.

5. Check the available electrical service
Power supply must be the same as that shown on the unit serial

nameplate. (See Use & Care Guide for serial plate location.) Power
cord is 48" long. Be sure you have an outlet near.

All models have a 3-prong service plug to provide proper service and
safe positive grouding. Do not change plug in any way. Do not use an
adapter plug. If your present wall outlet does not match your plug, call
a qualified electrician to make the needed change.

6. Carefully unpack air conditioner
Remove all packing material. Protect floor or other stable flat surface
with covering to prevent scratches from unit. With the aid of an
assistant, remove unit from styrofoam base and rest on protected

surface. Move and install unit with the aid of an assistant. Save
packing and shipping box for future unit storage.
