Installation

Complete step-by-step installation instructions are furnished
with your unit. These instructions will be found on a separate
page included with this manual or in the mounting kit
assembly. Follow these instructions carefully. Keep these
instructions with this manual for future reference. Your unit
will be one of the following three designs:

• Unit with a window mounting kit

These models are designed for mounting though an
opening in a wall. These units can be adapted to
window installation by using the optional window mount­ing kit supplied with your unit.

• Unit without a window mounting kit

No window mounting kit is supplied with the unit.
These models are designed for mounting through an
opening in a wall. These units can be adapted to
window installation by purchasing an optional window
mounting kit. Consult your dealer to choose the kit that
is appropriate for your model and installation.

• Unit with a separate sleeve

Some Builder models are designed such that the outer
case and the chassis can be purchased separately.
Through-the-wall installation instructions are included
with the outer case. These models can be adapted to
window installation by purchasing an optional mount­ing kit.

Room Heat Pumps

Heat pumps work by moving heat instead of creating it. In the
summer, the cool indoor coil absorbs heat from your room
and moves it outdoors, providing cooling. In the winter, heat
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.
For example, at 45°F outdoor temperature, a heat pump can
provide 2 ½ watts of heat for every watt of electricity it
consumes.

As outdoor temperatures drop, the heating capacity and
efficiency of the heat pump declines. At temperatures below
45°F, it is likely that ice will form on the outdoor coil. Heat
pump units are designed to operate as a heat pump above
approximately 40°F. Below 40°F, these units switch auto­matically from reverse cycle heat pump to auxiliary electric
heating. No defrost is required. There is no minimum
operating temperature.

Normal Care and Maintenance

WARNING

To avoid property damage, personal injury
or death due to electrical shock, turn fan
control OFF and remove plug from wall
outlet before inspecting unit or performing
maintenance.

Annual Inspection

It is suggested that your unit be inspected by your dealer or
servicer once a year. It is advisable to have the outer case
removed and the unit thoroughly cleaned.

Note: The life of your unit may be greatly reduced if you live
in a salt air or other corrosive type environment. Under these
conditions, the unit should be removed from its case and
completely cleaned at least once a year. At that time any
scratches or blisters on the painted surfaces should be
sanded and repainted. Placing an algaecide tablet in the
outdoor side of the unit’s basepan is suggested in humid
areas where algae formation is common.

Front Grille and Filter Removal

The front contains a removable grille that provides easy
access to the air filter. To clean the filter use one of the
following methods for filter removal:

METHOD ONE

Grasp filter handle and slide filter out of unit.

Optional Charcoal Air Filter Installation

Remove charcoal air filter from plastic bag. Insert three tabs
on right side of filter into three slots on filter frame. Carefully
bow middle of filter until two tabs on filter can be inserted into
two slots on filter frame. Relax bow.

Reinstall air filter and grille by reversing removal procedure.

Front Grille and Cabinet Cleaning

Grille and cabinet may be cleaned with warm water and mild
soap or detergent. Cleaning and polishing compounds are
not recommended, as they may damage plastic surfaces.

Air Filter Cleaning

A dirty air filter reduces operating efficiency of unit. Filter
should be inspected at least once every week during opera­tion. Clean filter with vacuum cleaner or wash in warm water
and mild detergent. Filter should be thoroughly dried before
replacing in unit. Do not operate unit without filter in place.

Fan Motor Care

The fan motor is permanently lubricated for long life. There is
no need to oil the motor.

Slide-out Chassis Removal from Outer Case

1. Remove front grille by sliding grille to left and pulling out.

2. Remove air filter by sliding to left.

3. Remove four screws holding plastic front to unit and

remove front.

4. If the unit has a screw holding the basepan clip to the

chassis, remove the screw.

CAUTION

To reduce the risk of personal injury be
sure to have sufficient help when moving
your unit. A room air conditioner can
weigh between 70 and 240 pounds.

5. Using basepan handle, pull chassis straight out, slowly

and evenly, until approximately 9-12 inches extends

CLIP

NOTE: Basepan clip is shipped in plastic bag with mounting

screw and condensate drain cup. Install clip after reinserting
chassis into outer case to prevent accidental chassis removal.

General Operating Instructions

While operation of all units is similar, controls vary slightly
from model to model. Operating Controls section shows
control panel of unit purchased and gives detailed information
about operation of controls.

Drain Cup Installation and Use

Your air conditioner uses a system where the water removed
from the indoor air (condensate) is channeled to the outdoor
side of the unit. The outdoor fan blade has a “slinger” ring
attached to it that dips into the water and slings the water onto
the outdoor coil surface. This is the sound of water you hear
during normal operation. The water quickly evaporates on
this warm surface and improves the efficiency of your air
conditioner. In normal conditions the unit can evaporate the
water as fast as it is removed from the indoor air.

However, in very humid conditions excess amounts of water
may drip off the unit chassis. If this proves to be a problem,
install the condensate drain cup included with the unit to
route excess water where it would not be a problem (see
illustration below).
To install, remove the unit chassis from the outer case. Insert
the condensate drain cup through the recessed ½” hole on
the right side bottom flange of the outer case. Once inserted,
place a ½” diameter hose or tube on the drain cup bottom
spout. The hose allows you to route where you want the
excess water to go. Reinsert the unit chassis into the outer
case. The unit basepan overflow hole will be positioned
directly above the drain cup and will catch any water that
might run out.

Initial Start-Up and Cooling

Select the highest fan speed and set temperature control to
its coldest position. When the desired temperature is
reached, slowly move the temperature control toward a
warmer setting until the compressor shuts off. The thermo­stat will then cycle the compressor on and off to maintain this
selected temperature. Adjust the fan speed for desired air
circulation.

Changing Airflow Direction Baffles

Airflow on unit may be diverted left or right from center by
baffles. Upward and downward air discharge is provided by
tilting louvers. Adjust baffles and tilt louvers for desired
airflow pattern.

Airflow Around Unit

Check the indoor grille and outdoor louvers for obstructions to
airflow. Do not block the airflow to and from the unit. If air is
obstructed and/or deflected back into the unit, the air
conditioner’s compressor may cycle on and off rapidly. This
could damage your unit.

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 Conditione

Introduction

This instruction sheet provides guidelines for
installing a compact air conditioner through an
outside wall.

General Instructions

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.

Air Conditioner Dimensions

The following figures show the outside dimensions of
air conditioner with chassis installed, and
dimensions of outer case with chassis removed.

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.

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
inches.
