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

Thru-wall Installation Instructions  
Kit RS100 for Soleus Air brand Compact Room Air Conditioner  
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)

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).  
Outercase must project

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.
