IMPORTANT SAFETY INSTRUCTIONS

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. It is used to alert
you to personal injury hazards. Obey all safety
messages that follow this symbol to avoid pos­sible injury or death.

UNDERSTAND SIGNAL WORDS

A signal word, when used with the safety alert
symbol, will identify a safety hazard and its level
of risk for personal injury. A signal word, without
the safety alert symbol, will be used for property
damage messages only.

WARNING indicates a hazard-

ous situation which, if not avoided, could result

in death or serious injury.

CAUTION, used with the safe-

ty alert symbol, indicates a hazardous situation

which, if not avoided, could result in minor or

moderate injury.

GENERAL INFORMATION

A. Product features or specications as described or il-

lustrated are subject to change without notice.

B. This air conditioner/heat pump (hereinafter referred to

as the "unit") 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 1.00 inch and maximum of 5.5 inches

distance between roof to ceiling of recreational

vehicle.

C. The ability of the air conditioner to maintain the de-

sired 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 ve-

hicle 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 opti-

mum or maximum efciency in high humidity or high

outside temperature.

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 Dometic 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 dur-

ing the cool of the evening.

D. Condensation

NOTICE is used to address

practices not related to personal injury.

Read and follow all safety information and
instructions to avoid personal injury.

Note: The manufacturer of this unit 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. During normal operation this unit
removes moisture from the air. Keeping doors and win­dows closed when this air conditioner is in operation will
minimize condensed moisture on cold surfaces.

FIG. 1

A. Precautions

PERSONAL INJURY HAZARD. Failure to obey
these installation instructions may cause seri­ous personal injury and/or property damage.

1. Read installation and operating instructions care­fully before attempting to start this unit installa­tion.

2. Dometic Corporation will not be liable for any
damages or injury incurred due to failure in fol-

lowing these instructions.

3. Installation MUST comply with the National Elec-
trical Code ANSI/NFPA-70 and CSA Standard

C22.1 (latest edition) and any State or Local

Codes or regulations.

4. Do NOT add any devices or accessories to this
unit except those specically authorized in writing
by Dometic Corporation.

5. This equipment MUST be serviced by qualied
personnel and some states require these people

to be licensed.

B. Choosing Proper Location For The Unit

This unit is specically 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. For one unit installation: The unit should be
mounted slightly forward of center (front to back)

and centered from side to side.

2. For two unit installations: Install one unit 1/3 and
one unit 2/3's from front of RV and centered from
side to side.

It is preferred that the unit be installed on a relatively at

and level roof section with the RV parked on a level sur-

face, but up to a 8° tilt is acceptable.

3. After Location Has Been Selected

a. Check for obstructions in the area where unit

will be installed. See FIG. 1.

b. The roof must be designed to support 130

pounds when the RV is in motion. Normally a
200 lb. static load design will meet this require-

ment.

PROPERTY DAMAGE HAZARD. It is the re­sponsibility of the installer of this system
to ensure structural integrity of the RV roof.
Never create a low spot on the roof where
water will collect. Failure to obey this warn­ing may cause water damage to the product
and the RV.

c. Check inside the RV for air distribution box

obstructions. (i.e. door openings, room divid­ers, curtains, ceiling xtures, etc.) See FIG. 2.

C. Roof Preparation

1. Opening Requirements - Before preparing the

ceiling opening, the type of system options must
be decided upon. Read all of the following instruc­tions before beginning the installation.

SHOCK HAZARD. There may be electrical
wiring between the roof and the ceiling. Dis­connect 120 VAC power supply and the posi­tive (+) 12 VDC terminal at the supply battery.
Failure to obey this warning may cause death
or severe personal injury.

2. Mark a 14-1/4" x 14-1/4" (±1/8") square on the

roof and carefully cut the opening. The 14-1/4"

x 14-1/4" (±1/8") opening is part of the return air
system of the unit and MUST be nished in ac­cordance with ANSI A 119.2.

3. Using the roof opening as a guide, cut the match­ing hole in the ceiling.

4. The opening created must be framed to provide
adequate support and prevent air from being
drawn from the roof cavity. Framing stock 3/4"
thick or more must be used. Remember to pro-

vide an entrance hole at the front of the opening
for power supplies, indoor temperature sensor (if

applicable), communication cable, and furnace
wiring (if applicable). See FIG. 3.

D. Wiring Requirements

1. Route a copper, with ground, 120 VAC supply
wire from the time delay fuse or circuit breaker
box to the roof opening. The proper size wire can
be determined from the chart on page 3.
a. This supply wire must be located in the front

portion of the 14-1/4" x 14-1/4" (±1/8") open­ing.

b. The power MUST be on an appropriately

sized separate time delay fuse or circuit
breaker. The proper size protection can be

determined from the chart on page 3.

c. Make sure at least 15" of supply wire extends

into the roof opening. This insures an easy
connection at the junction box.

d. Wiring MUST comply with National Electri-

cal Code ANSI/NFPA-70 and CSA Standard

C22.1 (latest edition) and any State or Local

Codes or regulations.

e. Protect the wire where it passes into the

opening with approved method. See para-

graph "d" above.

2. Route a dedicated 12 VDC supply wire (18-22
AWG) from the RV's converter (ltered side) or
battery to the roof opening.

Note: When a Comfort Control Center (hereinafter re-

ferred to as CCC) thermostat is being installed with mul­tiple zones, this 12 VDC supply wire needs to be supplied
to the unit designated zone 1 only.

PROPERTY DAMAGE HAZARD. It is the re­sponsibility of the installer of this system to
ensure structural integrity of the RV roof. Never
create a low spot on the roof where water will
collect. Failure to obey this warning may cause
water damage to the product and the RV.

Note: When a Comfort Control Center 2 (hereinafter

referred to as CCC 2) thermostat is being installed with
more than 2 zones, route a dedicated 12 VDC supply wire

(18-22 AWG) to zone 1 and zone 3 roof opening.

a. This supply wire must be located in the front

portion of the 14-1/4" x 14-1/4" (±1/8") open­ing.

b. Make sure that at least 15" of supply wire ex-

tends into the roof opening.

3. Route an indoor temperature sensor (Optional)
from the roof opening to the indoor temperature
sensor location. The 2 pin connector end goes to
the roof opening. See indoor temperature sensor
installation instructions for proper sensor loca­tion.

4. Thermostat Control Cable

a. CCC, CCC 2 & Digital thermostat.

i. Route a 4 conductor communication ca-

ble from the 14-1/4" x 14-1/4" (±1/8") roof

opening to the thermostat mounting loca­tion. Review section E "Choosing Ther-

mostat Location" before routing com­munication cable. Choose the shortest

most direct route. Make sure that at least
15" of wire extends into the roof opening
and 6" extends from the wall at the thermo­stat mounting location.

5

Important: When more than one unit is being in-

stalled (additional zones) with the CCC and CCC 2
thermostat, an additional 4 conductor communica­tion cable must be routed to each additional unit 14­1/4" x 14-1/4" (±1/8") roof opening. Make sure at least
15" of wire extends into the roof opening. See FIG. 25.

b. Analog Thermostat

i. Route a 7 conductor cable, 18 to 22 AWG,

from the 14-1/4" x 14-1/4" (±1/8") to the
thermostat mounting location. Review sec-

tion E "Choosing Thermostat Location"
before routing cable. Make sure 15" of

the wire extends into the roof opening and
6" of wire extends from the wall at the ther­mostat mounting location.

c. LCD Thermostat

i. Route a 3 conductor cable, 18 to 22 AWG,

from the 14-1/4" x 14-1/4" (±1/8") roof open­ing to the Single Zone LCD (hereinafter re­ferred to as SZLCD) thermostat mounting
location. Review section E "Choosing

Thermostat Location" before routing
cable. Make sure that at least 15" of the

wire extends into the roof opening and 6"
extends from the wall at the thermostat
mounting location.

5. If system includes a gas furnace, route two 18

gauge thermostat wires from the furnace to the
roof opening of the unit that will control it. If more

than one furnace is to be used, route the second

set of thermostat wires to the second unit. Make
sure that 6" of wire extends into the opening.

6. Energy Management System (CCC and CCC 2
Only)
a. If an Energy Management System (load shed

feature) is to be used with the control, two
wires must be routed to the roof opening of
the zone to be managed. The signal required
for this function is normally an open relay

Zone 1 and no dip switch setting is required.

Each additional unit must be assigned a zone

(2 through 4). Each unit must have a different
zone setting.

b. Heat strip selection - On heat strip models

the #1 dip switch is in the "ON" position from

the factory. Non heat strip models leave in

the "OFF" position.

c. Furnace selection - when a furnace has been

connected to a zone, place the furnace dip

switch “ON” for that zone.

d. Differential - differential is the temperature

difference between the “ON/OFF” cycle of

the thermostat in the furnace mode. The nor-

mal 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 com-

fort 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.

MAINTENANCE

A. Air Filters

1. Periodically (a minimum of every 2 weeks of op-

eration) slide out the return air lters located on
the end of the air distribution box. Wash the lters
with soap and warm water, let dry and then rein-

stall.

Note: To insure easy future removal the lters need to be

replaced with the domed side of their handle positioned
towards the ceiling.

Note: Never run the unit without both return air lters in

place. This will plug the unit evaporator coil with dirt and

may substantially degrade the performance of the unit

over time.

D. Frost Formation On Cooling Coil

1. Frost on a small portion of the coil is not unusual.

Under certain conditions, ice may form on the
evaporator coil. This is indicated by very cold out­put at very low air speed and the icing can be
seen through the hole network with the lters re­moved. If this should occur, inspect the lter and
clean if dirty. Make sure air vents are open and
not obstructed. Units 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, operate on
any fan ONLY setting until the cooling coil is free
of frost; then resume normal operation. If frost
condition persist, contact your local service cen­ter for assistance.

SERVICE-UNIT DOES NOT OPERATE

If your unit fails to operate or operates improperly, check
the following before calling your service center.

A. If RV connected to motor generator, check to be sure

motor generator is running and producing power.

B. If RV connected to power supply by a land line, check

to be sure line is sized properly to run unit load and it
is plugged into power supply.

C. Check your fuse or circuit breaker to see if it is open.

Insure fuse is not burnt, or circuit breaker is "ON"

and not activated.

D. After the above checks, call your local service center

for further help. This unit must be serviced by quali­ed service personnel only.

E. When calling for service, always give the following:

1. Unit model and serial number found on identication
label located on base pan of unit bottom. (Remove
lter and view through network of holes)

2. Air distribution box model and serial number found
on rating plate located on ceiling template. Observe
this rating plate through the air distribution box right

side vent opening.

B. Air Distribution Box Housing

1. Clean air distribution box housing with a soft cloth

dampened with a mild detergent. Never use furni­ture polish or scouring powders.

C. Fan Motor

1. The blower motor is factory lubricated and re­quires no service.
