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
windowinstallationbyusingtheoptionalwindow mount-
ing 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 mount-
ing kit.
RoomHeatPumps
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 auto-
matically from reverse cycle heat pump to auxiliary electric
heating. No defrost is required. There is no minimum
operating temperature.
NormalCare andMaintenance
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.
WARNING
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.
To avoid property damage, personal injury
or death due to electrical shock, turn unit
OFF and remove plug from wall outlet before
inspecting unit or performing maintenance.
Note: The life of your unit may be greatly reduced if you live in a
corrosive environment such as an oceanside location with salty
air. 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.

GeneralOperatingInstructions
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.
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 thermo-
stat 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.

Drain Cup Installation and Use(on some models)
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.

Switchover Thermostat Control
Emergency heat switch overrides heat pump (compressor)
and starts auxiliary electrical heater. When switch is ON,
heat pump is locked out.
• Use emergency switch only when heat pump fails to
provide adequate heat. Cause of heat pump malfunc-
tion should be determined by authorized servicer. Cost
of operating unit will increase when emergency heat
switch is engaged.
To access and engage emergency switch:
1. Remove front grille, air filter, and plastic front, as de-
scribed in Installation Instructions.
2. Remove basepan clip.
3. Slide chassis out of case about two inches.
4. Locate access hole for emergency switch above label on
right front of control box.
5. To start emergency heat, insert flathead screwdriver into
slot and turn counterclockwise until switch-stop is reached.
6. Return chassis to case.
7. Replace basepan clip, plastic front, air filter, and front
grille.
