INSTALLATION INSTRUCTIONS
Safety Instructions
GENERAL INFORMATION
A. This air conditioner is designed for:
1. Installation on a recreational vehicle during or after
the time the vehicle is manufactured.
2. Mounting on the roof of a recreational vehicle.
3. Roof construction with rafters/joists on minimum
of 16 inch centers.
4. Minimum of 1.00 inch and maximum of 5.5 inches
distance between roof to ceiling of recreational
vehicle.
B. The ability of the air conditioner to maintain the desired
inside temperature depends on the heat gain of the RV.
Some preventative measures taken by the occupants
of the RV can reduce the heat gain and improve the
performance of the air conditioner. During extremely
high outdoor temperatures, the heat gain of the vehicle
may be reduced by:
1. Parking the RV in a shaded area
2. Using window shades (blinds and/or curtains)
3. Keeping windows and doors shut or minimizing
usage
4. Avoiding the use of heat producing appliances
Operation on High Fan/Cooling mode will give
optimum or maximum efficiency in high humidity
or high outside temperature.
This manual has safety information and instructions to help users eliminate or reduce the risk
of accidents and injuries.
Recognize Safety Information
This is the safety-alert symbol. When you see this
symbol in this manual, be alert to the potential
for personal injury.
Follow recommended precautions and safe operating instructions.
Understand Signal Words
A signal word , WARNING OR CAUTION is used
with the safety-alert symbol. They give the level
of risk for potential injury.
Starting the air conditioner early in the morning
and giving it a "head start" on the expected high
outdoor ambient will greatly improve its ability to
maintain the desired indoor temperature.
For a more permanent solution to a high heat gain,
accessories like A&E outdoor patio and window
awnings will reduce heat gain by removing the direct
exposure to the sun. They also add a nice area to
enjoy company during the cool of the evening.
indicates a potentially hazardous situation which, if not avoided, could result
in death or serious injury.
C. Condensation
Note: The manufacturer of this air conditioner will not be
responsible for damage caused by condensed moisture on
ceilings or other surfaces. Air contains moisture and this
moisture tends to condense on cold surfaces. When air
enters the RV, condensed moisture may appear on the
ceiling, windows, metal parts, etc. The air conditioner
removes this moisture from the air during normal operation.
Keeping doors and windows closed when this air conditioner
is in operation will minimize condensed moisture on cold
surfaces.
indicates a potentially hazardous situation which, if not avoided may result in
minor or moderate injury.
used without the safety alert
symbol indicates, a potentially hazardous situation which, if not avoided may result in property
damage.
Read and follow all safety information and instructions.

1/3 L
2. CHOOSING LOCATION FOR THE
AIR CONDITIONER
This air conditioner is specifically designed for installation on the roof of a recreational vehicle (RV).The roof
must support 130 pounds when the RV is in motion.
Normally a 200 lb. static load design will meet this
requirement. Insure the roof will support the appliance
and the installer personnel.
This air conditioner should be installed in a
relatively flat and level roof section with the
RV parked on a level surface; however, up to
15o slant to either side, or front-to-back, is acceptable on 520 Series units and a 8° slant to
either side, or front to back, is acceptable for
600, 620 and 630 Series units.
C. AFTER LOCATION SELECTION:
1.
Check inside the RV for air box obstructions.
(i.e. door openings, room dividers, curtains,
ceiling fixtures, etc.) See FIG. 3 & 4.
It is the responsibility of the installer of this
air conditioner system to ensure structural
integrity of the RV roof. Never create a low
spot on the roof where water will collect.
Water standing around the air conditioner
may leak into the interior causing damage
to the product and the RV.
12-3/4"
A. NORMAL LOCATIONS:
The air conditioner is designed to fit over an existing roof vent opening. When the vent is removed, it
normally creates a 14-1/4" x 14-1/4" ±1/8 opening.
B. OTHER LOCATIONS:
When no roof vent is available or another location is
desired, the following is recommended:
1.
For one unit installation: The air conditioner
should be mounted slightly forward of center
(front to back) and centered from side to side.

B. NEW OPENING:
(Installations Other Then Vent Openings)
1. A 14-1/4" x 14-1/4"±1/8 opening must be cut through
the roof and ceiling of the RV. It is recommended
this opening be located between roof reinforcing
members.
2. Mark a 14-1/4" x 14-1/4"±1/8 square on the roof
and carefully cut the opening.
3. Using the roof opening as a guide, cut the matching
hole in the ceiling. See FIG. 4.
C. OPENING PREPARATION:
1. If the opening exceeds 14-3/8" x 14-3/8", it will be
necessary to install spacers.
2. If the opening is less than 14-1/8" x 14-1/8", it must
be enlarged.

B. COOLING OPERATION:
1.
Set the thermostat at the desired temperature
level.
2.
Select the cooling mode that best satisfies your
needs:
a. HIGH COOL: Selected when maximum
cooling and dehumidification required.
b. LOW COOL: Selected when room at
desired comfort level and needs to be
maintained. Normally this speed used for
night time operation.
Note: The compressor and blower will come on as cooling
is required to maintain the selected temperature level.
B. AIR BOX HOUSING:
Clean air box housing and control panel with a soft
cloth dampened with a mild detergent. Never use
furniture polish or scouring powders.
C. FAN MOTOR:
Factory lubricated and requires no service under
normal use.
D. FROST FORMATION ON COOLING COIL:
Under certain conditions, frost may form on the
evaporator coil. If this should occur, inspect the filter
and clean if dirty. Make sure air louvers are not obstructed. Air conditioners have a greater tendency to
frost when the outside temperature is relatively low.
This may be prevented by adjusting the thermostat
control knob to a warmer setting (counter clockwise).
Should frosting continue, turn off the compressor and
operate on LOW or HIGH FAN setting until the cooling
coil is free of frost.
If your unit fails to operate or operates improperly, check
the following before calling your service center.
