IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING.
WARNING!
For your safety, the information in this manual must be followed to minimize the risk of fire, electric shock
or personal injury.
■ This system must be properly installed in
accordance with the Installation Instructions
before it is used.
■ Be certain the power source is disconnected
before servicing the product.
NOTES:
■ We strongly recommend that any servicing
be performed by a qualified individual.
■ Since outdoor condensing unit has a sump
heater on the compressor for heat pump
models, the power should be turned on at
least 5 hours before unit operation. Leave
the power on unless you will not be using the
system for an extended period of time.
For any service which requires entry
into the refrigerant sealed system,
Federal regulations require the work
be performed by a technician having a
Class II or Universal certification.

Indoor Unit
Grille, Case and Remote Control
Turn the system off before cleaning. To clean, wipe
with a soft, dry cloth. Do not use bleach or abrasives.
Air Filters
The two air filters behind the front grille should be
checked and cleaned at least every 30 days or more
often if necessary.
Lift the front access panel and pull the filter tab
slightly forward to remove the filter. Clean the filter
with a vacuum or warm, soapy water. Rinse and let
the filter dry before replacing it.
CAUTION: DONOT operate the system without a filter
because dirt and lint will clog it and reduce performance.
Outdoor Unit
The heat exchanger coils and panel vents of the
outdoor unit should be checked regularly. If
clogged with dirt or debris, the heat exchanger and
panel vents may be professionally steam cleaned, a
service available through your GE service outlet.
NOTE:
■ Supply power must be disconnected before cleaning the
outdoor unit.
■ Dirty or clogged coils will reduce the operating efficiency of
the system and cause higher operating costs.

Care and cleaning of the air conditioner.
CAUTION: Before performing any maintenance, turn off the main power to the system.

■ Do not use an extension cord with this system.
■ Aluminum building wiring may present special problems—consult a qualified electrician.
■ When the unit is in the STOP position, there is still voltage to the electrical controls.
■ Disconnect the power to the system before servicing by removing the branch circuit fuses
or turning the circuit breakers off at the panel.
CAUTION
■ Be certain all wiring complies with local building codes and NEC and that the supply voltage for this
system is correct. The system supply voltage is connected to the outdoor unit only.
■ Check the rating nameplate on side panel of outdoor unit for required circuit protection rating and
required supply voltage.
■ Use Underwriters-approved electrical branch circuit disconnect for providing supply voltage to split
system outdoor unit. Locate disconnect within sight and readily accessible from outdoor unit.
■ The split system indoor unit requires low voltage (D.C.) supplied from the outdoor unit via
interconnecting wiring. The interconnecting wiring between indoor and outdoor units of this
system must be 18–4 wiring, 18-gauge (minimum), 300-volt rating, type SJO–WA or STO–WA.
■ Be certain there is an uninterrupted, unbroken electrical ground connection.

Select the Best Location
Indoor Unit.
■Do not have any heat or steam near the unit.
■Select a place where there are no obstacles in
front of the unit.
■Make sure that condensate drainage can be
conveniently routed away.
■Do not install near a doorway.
■Ensure that the space around the left and right
of the unit is more than 2². The unit should be
installed as high on the wall as possible, allowing a
minimum of 3²from ceiling.
■Use a stud finder to locate studs to prevent
unnecessary damage to the wall.
Outdoor Unit.
■If an awning is built over the unit to prevent direct
sunlight or rain exposure, make sure that heat
radiation from the condenser is not restricted.
■Ensure that the space around the back and sides
is more than 4². The front of the unit should have
more than 28²of space.
■Construct and anchor a strong and level
mounting base or pad for the outdoor unit.
■Use the provided rubber grommets between
the unit’s four mounts and the base or pad.
■Anchor the outdoor unit through its four
mounts using bolts.
■ Rooftop Installations:
If the outdoor unit is installed on a roof structure,
be sure to level the unit. Ensure the roof structure
and anchoring method are adequate for the unit
location. Consult local codes regarding rooftop
mounting.

Indoor Unit Installation
The wall you select should be strong and solid
enough to protect it from vibration.
NOTE: These instructions do not cover all
installations. However, the typical installation will be
to secure the installation plate to wall studs 16²apart.
It is recommended that a stud finder be used to
locate the wall studs.
Measure the wall and mark the centerline. It is
also important to use caution concerning the
location of the installation plate—routing of
the wiring to power outlets is through the walls
typically. Drilling the hole through the wall for
piping connections must be done safely.
Mount the installation plate on the wall with
four type A screws. If mounting the unit on a
concrete wall, use anchor bolts.
Mount the installation plate horizontally by
aligning the centerline using a level.
Drill the piping hole with a 23⁄4–3²hole core
drill. Drill the piping hole at either the right or
the left with the hole slightly slanted to the
outdoor side (see illustration below).
(See templates in the back of this manual for hole location relative
to the installation plate.)
NOTES:
■For right rear piping, draw a line in the direction of
the arrow marked “A” and make another line
extending from the bottom line of the installation
plate. The meeting point of the two lines is the
center of the hole.
■For left rear piping, draw a line extending left
from the bottom line of the installation plate.
This is the center line of any hole for the left rear
installation.

Refrigerant Piping and Condensate Drain–Indoor Unit
Optional tubing kits are available which consist
of all interconnecting copper lines, wiring
needed to connect indoor to outdoor units,
and a plastic sleeve endcap to enhance the
installation wall hole sealing. You may also
purchase the tubing, insulation, wiring, etc.,
locally for the installation. See chart on page 14
for tubing diameter sizes required for the
different models.
NOTE: Since the refrigerant metering device is
located in the outdoor unit, both the gas and the
liquid tubing line sets must be insulated. Armaflex
material is recommended.
*For heat pump models, heat-resistant insulation material
with minimum rating of 230° F is required.
See chart on page 14 for maximum lengths of
tubing for interconnecting units. The indoor
and outdoor units are provided with flare nuts.
See the brass fittings on the indoor/outdoor
sections.
NOTE: The indoor unit is shipped from the factory
with a nitrogen holding charge to prevent moisture
contamination during shipment. Remove the flare
nuts on the indoor unit to vent the nitrogen
(environmentally friendly) into the atmosphere.
Measure distance between indoor and outdoor
units, considering the routing for the piping
and wiring. Cut tubing to lengths, insert the
tubing insulation. Flare the ends of tubes, after
inserting flare nuts that will connect to the
indoor and outdoor units.

Preparing the indoor unit’s piping and drain
hose for installation through the wall.
Remove the plastic tubing retainer (see
illustration below) and pull the tubing
and drain line away from chassis.
Replace the plastic tubing holder in the original
position.
FOR RIGHT REARPIPING:
Route the tubing and the drain hose straight
backwards.
Insert the connecting wiring cable into the
indoor unit from the outdoor unit through
the piping hole.
1 Do not connect the cable to the indoor unit.
2 Make a small loop with the cable for easy
connection later.
NOTE: Wiring must comply with local and NEC
codes. The interconnecting wiring between
indoor and outdoor units of this system must be
18–4 wiring, 18-gauge (minimum), 300-volt rating,
type SJO-WA or STO-WA.
Tape the tubing, drain hose and the connecting
cable. Be sure that the drain hose is located at
the lowest side of the bundle. Locating at the
upper side can cause drain pan to overflow
inside the unit.
NOTE: If the drain hose will be routed in the room,
insulate the hose with an insulation material*so
that dripping from “sweating” (condensation) will
not damage furniture or floors.
*Foamed polyethylene or equivalent is
recommended.
