SAFETY INSTRUCTIONS
GENERAL INFORMATION
A. Product features or specifications as described or illus-
This manual has safety information and instructions to help users eliminate or reduce the risk of
accidents and injuries.
trated are subject to change without notice.
B. This Air Conditioner Is Designed For:
1. Installation on a recreational vehicle during 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 2.00 inches and maximum of 5.50
inches distance between roof to ceiling of recreational vehicle. Alternate installation methods will
allow forroofs more than 5.50 inches thick.
RECOGNIZE SAFETY INFORMATION
!
C. 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 us
age
4. Avoiding the use of heat producing appliances
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
Operation on High Fan/Cooling mode will give optimum or
maximum efficiency in high humidity or high outside temperatures.
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.
! WARNING indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
For a more permanent solution to high heat gain, accessories like A&E outdoor patio and window awnings will reduce
heat gain by removing the direct sun. They also add a nice
area to enjoy company during the cool of the evening.
! CAUTION indicates a potentially hazardous situation which, if not avoided may result in
minor or moderate injury.
D. Condensation
CAUTION
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.

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.
This air conditioner is specifically designed for installation on
the roof of a recreational vehicle (RV). When determining your
cooling requirements, the following should be considered:
• Size of RV;
• Window area (increases heat gain);
• Amount of insulation in walls and roof;
• Geographical location where the RV will be used;
• Personal comfort level required.
1. Normal Location-The air conditioner is designed to
fit over an existing roof vent opening.

5. Air Distribution System Installation
a. Dometic Corporation recommends the basic
configuration shown on page 7, for installing
this air conditioner system. We have found by
testing, that this configuration works best in
most applications of this air conditioner system. It is the responsibility of the Installer of this
system to review each RV floor plan and determine the following:
• Duct size
• Duct layout
• Register size
• Register location
• Thermostat location
4. Air Distribution System Sizing & Design
CAUTION
It is the responsibility of the installer to insure
the ductwork will not collapse or bend during
and after the installation. Dometic Corporation
will not be liable for roof structural or ceiling
damage due to improperly insulated, sealed
or collapsed ductwork.
The Installer of this air conditioner system must
design the air distribution system for their particular
application. Several requirements for this system
MUST be met for the air conditioner to operate
properly. These requirements are as follows:
a. The duct material must meet or exceed any
agency or RVIA Standard that may be in existence at the time the RV is produced.
b. All discharge air ducts must be properly insulated to prevent condensation from forming on
their surfaces or adjacent surfaces during operation of the air conditioner. This insulation
must be R-7 minimum.

d. Differential - differential is the temperature difference between the "ON/OFF" cycle of the thermostat in the furnace mode. The normal differential is preset in the circuit board with the dip
switch set to the "OFF" position. In some
situations, it may be necessary to decrease the
differential. The location of the thermostat may
create a condition where the normal differential
will not maintain your comfort zone. If this
occurs, the differential can be shortened by
placing the differential dip switch to the "ON"
position.
Note: Setting the differential dip switch should only be
required when installation conditions are less than desirable
and is not covered under the limited warranty.
e. Stage selection - stage is not used on these
units. Leave in the "OFF" position.
f. Gen start selection - leave in the "OFF" position.
g. Replace the unit electrical box cover.
h. Repeat this procedure for each additional zone.
2. System Reset
After setting the dip switches in the electronic
control kit, do a system reset.
a. Turn the ON/OFF switch to the "OFF" position.
b. Simultaneously depress and hold the MODE
and ZONE push-buttons while turning the ON/
OFF switch to "ON". FF should appear in LCD
display until the mode and zone push-buttons
are released.
c. When a dip switch is turned on after initial
configuration, a system reset will need to be
done before the Comfort Control Center™ will
recognize the updated selection.
3. System Checkout
Verify that all features of the installed system work.
Check fan speeds, cooling mode, heat pump mode,
furnace (if connected) and heat strip. If the features
do not work, check all wiring and confirm that the
correct options have been selected on the Electronic Control Box. See Comfort Control Center™
Operating Instructions.
