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.
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
temperatures.
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 high heat gain, accessories like Dometic 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.

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.
It is the responsibility of the installer to insure
the duct work will not collapse or bend during and after the installation. Dometic, LLC
will not be liable for roof structural or ceiling
damage due to improperly insulated, sealed
or collapsed duct work.
There may be electrical wiring between the
roof and the ceiling. Disconnect 120 VAC
power cord and the positive (+) 12 VDC terminal at the supply battery. Failure to follow
this instruction may create a shock hazard
causing 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 finished in accordance with
NFPA Standard 501C Section 2.7.2.
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" or more
in thickness must be used. Remember to provide
an entrance hole for power supplies, indoor temperature sensor cable (if applicable), 4 conductor
communication cable, and furnace wiring (if applicable).
The Installer of this system must design the air distribution system for their particular application. Several
requirements for this system MUST be met for the
unit to operate properly. These requirements are as
follows:
1. The duct material must meet or exceed any agency
or RVIA Standard that may be in existence at the
time the RV is produced.
2. All discharge air ducts must be properly insulated
to prevent condensation from forming on their

from the time delay fuse or circuit breaker box
to the roof opening. The proper size wire can be
determined from chart on page 3.
a. This supply line 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 a separate time delay fuse or HACR 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 NFPA 70: National
Electrical Code regulations and any State or
Local Codes or regulations.
e. Protect the wire where it passes into the
opening with approved method. See paragraph "d" above.
2. Route a dedicated 12 VDC supply line (18-22
AWG) from the RV's converter (filtered side) or
battery to the roof opening.
F. Choosing Thermostat Location
1. CCC 2 Location
a. If the system is to be used without an indoor
temperature sensor, the proper location of
the CCC 2 thermostat is very important to
ensure that it will provide a comfortable RV
temperature. Observe the following rules when
selecting a location:
• Locate the CCC 2 thermostat 54” above
the floor.
• Install the CCC 2 thermostat on a partition,
not on an outside wall.
• NEVER expose it to direct heat from lamps,
sun or other heat producing items.
• Avoid locations close to doors that lead
outside, windows or adjoining outside
walls.
• Avoid locations close to supply registers
and the air from them.
b. If the system is to be used with an Indoor
Temperature Sensor in ALL zones, the CCC 2
thermostat may be mounted anywhere that is
convenient in the coach. Try to avoid hard to
reach and hard to see areas.
• Refer to the instructions provided with the
Indoor Temperature Sensor for details of
installation.
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 line
(18-22 AWG) to zone 1 and zone 3 roof opening. a. This supply line 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 extends 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. Route a 4 conductor communication cable from
the CCC 2 thermostat mounting position into
the 14-1/4" x 14-1/4" (±1/8") roof opening. Make
sure that at least 15" of the wire extends into the
roof opening and 6" extends from the wall at the
mounting position of the CCC 2 thermostat. See
Section F.
Important: When more than one unit is being installed (additional zones) with the CCC 2 thermostat,
an additional 4 conductor communication cable must
be routed to each additional unit 14-1/4" x 14-1/4"
(±1/8") roof opening. Make sure at least 15" of the
wire extends into the roof opening. See FIG. 4.
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. 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 contact. When the EMS
calls for the compressor to shut off, the relay contacts should close. Make sure at least 15" of the
EMS wire extends into the roof opening.
7. If an Automatic Generator Start (AGS) kit will be
installed, an additional 4 conductor communication cable must be routed from the last unit to the
location of the AGS kit. Follow AGS kit instructions for installation.
