pumps reverse this operation. By lowering the temperature
of the outdoor coil below the outdoor temperature, the heat
pump absorbs the heat from outdoors and moves it inside
your house. This heat transferring process is very efficient.

ELECTRICAL REQUIREMENTS
The 3-prong grounding plug minimizes the possibility
of electric shock hazard. If the wall outlet you plan to
use is only a 2-prong outlet, it is your responsibility to
have it replaced with a properly grounded 3-prong
wall outlet.
Some models require 230/208-volt a.c.,
protected with a time delay fuse or circuit
breaker. These models should be installed
on their own single branch circuit for
best performance and to prevent
overloading house or apartment wiring
circuits, which could cause a possible
fire hazard from overheating wires.
Power cord includes a current interrupter device. A
test and reset button is provided on the plug case.
The device should be tested on a periodic basis by
first pressing the TEST button and then the RESET
button. If the TEST button does not trip or if the
RESET button will not stay engaged, discontinue use
of the air conditioner and contact a qualified service
technician.

Thru-wall Installation Instructions
Introduction
General Instructions
This instruction sheet provides guidelines for
installing a compact air conditioner through an
outside wall.
All Soleus Air brand Compact Room Air Conditioners
feature a slide-out chassis. Chassis and front cover
must be removed from outer case for installation.
Installing an air conditioner through a wall requires
extensive carpentry and/or masonry experience.
Thru-wall installations performed by inexperienced or
unqualified individuals can result in costly damage to
home.
In order to reinstall the chassis and reattach the air
conditioner front cover, the installed outer case must
be square and level from side to side. Use wood
shims between sides of case and finished opening–
especially where case is secured to opening–to
prevent warping or distorting. Check installed case for
distortion using carpenter’s square.
Air Conditioner Dimensions
The following figures show the outside dimensions of
air conditioner with chassis installed, and
dimensions of outer case with chassis removed.
A finished opening 26 1/8 - inches wide x 17-inches
high is recommended. The lower left inside corner of
opening must be within 5 feet of an appropriate
electrical outlet (see Use and Care manual for
electrical requirements.)
When wall thickness exceeds 9 -inches, opening
must be modified to allow air to enter side louvers on
case (see special instructions on back ). Do not
install air conditioner in walls thicker than 11 2/5 -
inches.
Air Conditioner Dimensions
(with chassis installed)
Dimensions of Finished Opening
Masonry Construction
See CAUTION under General Instructions. In
masonry walls, cut or build a finished opening 17-
inches high by 261/8-inches wide. When case is
properly positioned in opening, secure it in place
with mortar or concrete nails driven through holes in
sides of outer case (shim case and predrill holes
before securing with nails).
Outer Case Dimensions
(chassis removed)
15
When case is properly positioned in opening, use wood
shims to fill any gaps between case and finished opening,
especially in area where case will be secured to opening.
Take care not to warp or distort case when installing
shims. For condensate drainage, install drainage cup in
drain hole on baseplate of case.
Brick Veneer or Frame Wall Construction.
See CAUTION under General Instructions. Cut or build
rough opening large enough to allow a framed, finished
opening 17-inches high and 261/8-inches wide. When case
is properly positioned in opening, secure it to framing
material with nails or screws driven through holes in sides
of outer case (shim case and predrill holes before
securing).

Placement of Outer Case in Opening
Place outer case in opening, flush against one side of
opening. Use carpenter’s level and ensure case is level
from side to side and has a 3/8-inch slope from front to back
(back of case must be 3/8-inch lower than front to ensure
proper condensate drainage). If needed, use shims to level
case (from side to side) and to obtain proper back slope.
Installed Case
(brick veneer or frame wall construction shown)
Installation in Wall Thicker Than 9-inches
The side louvers in outer case provide ventilation to air
conditioner compressor and fan motor and must not be
blocked. When installing unit in a wall over 9-inches
thick, provisions must be made in wall opening to ensure
free air flow to the side louvers. This can be accomplished
by chamfering the vertical portions of the outside opening
as shown.
Front of case must project ¾-inch (minimum) beyond
inside wall in order to attach air conditioner front frame. If
framing indoor side of opening with wood molding (or other
decorative material), extend outer case ¾-inch beyond
molding.
Ventilation louvers on top of case must not be obstructed.
Do not attempt to install unit in walls thicker than
112/5-inches.
