FIG. 3
Dimensions Are Nominal
B. Roof Preparation
1. FIRE OR ELECTRICAL SHOCK HAZARD. Make sure there are no obstacles (wires, pipes, etc.) inside RV's [roof / floor / walls]. Shut O FF gas supply, disconnect 120 Vac power from RV, and disconnect positive (+) 12 Vdc terminal from supply battery B EFORE drilling or cutting into RV. Failure to obey these warnings could result in death or serious injury.
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.
2. Carefully mark and cut the required roof opening. See "B. Roof Requirements" on page (4).
3. Using the roof opening as a guide, cut the matching hole in the ceiling.
4. Maintain structural integrity. Otherwise damage to product and/or RV could occur.
5. NEVER create a low spot on RV roof. Otherwise, water will pool and could cause a leak.
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 (if applicable), thermostat communication cable, and furnace wires (if applicable) at the front of the opening. See (FIG. 4).

C. Air Distribution Duct Sizing & Design
The installer of this system must design the air distribution system for their particular application. Several requirements must be met for the unit to operate properly. These requirements are as follows:
1. Make sure ductwork will NOT bend or collapse during and after installation, and that it is correctly insulated and sealed. Otherwise, damage to roof structure and ceiling could occur.
2. All discharge air ducts must be properly insulated to prevent condensation from forming on their surfaces or adjacent surfaces during operation of unit. This insulation must be R-7 minimum. See (FIG. 5).

3. Ducts and their joints must be sealed to prevent condensation from forming on adjacent surfaces during operation of the unit.
4. Return air openings must have 40 square inches minimum free area including the filter.
5. Return air to the unit must be filtered to prevent dirt accumulation on unit cooling surface.
6. Air Distribution System Installation
a. Dometic Corporation recommends the basic configuration shown in (FIG. 6), for installing this system. We have found by testing, that this configuration works best in most applications. It is the responsibility of the installer to review each RV floor plan to determine the following:
Duct size
Duct layout
Register size
Register location
Thermostat location
Indoor Temperature Sensor Location
These items must be determined in conjunction with the Air Distribution Duct System Sizing & Design requirements. See "C. Table - Air Distribution Duct Sizing & Design" on page (5).
Alternate configurations and methods may be used which will allow the unit to operate properly; however, these alternate configurations and methods MUST be approved by Dometic Corporation in writing. The following instructions are based upon the use of RAG Kits 3105007.XXX & 3105935. XXX.

INSTALLATION INSTRUCTIONS
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. Use a listed/certified non metallic - sheathed single strand cable. See "A. Table - Unit Data" on page (4).
a. This supply wire must be located in the front
portion of the roof opening.
b. The power MUST be on an appropriately sized separate time delay fuse or circuit breaker. See "A. Table - Unit Data" on page (4).
c. Make sure that at least 15 of supply wire
extends into the roof opening This ensures
an easy connection at the junction box.
d. Protect the wire where it passes into the opening with approved method.
2. Route a dedicated 12 Vdc supply wire (18-22
AWG) from the RV converter (filtered side) or
battery to the roof opening. When a Comfort Control Center 2 (here-
E.
in-after 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 open-
ing.
a. This supply wire must be located in the front
portion of the roof opening.
b. Make sure that at least 15 of supply wire extends into the roof opening.
3. Route a 4 conductor communication cable from
the roof opening to the thermostat mounting lo-
cation using the shortest most direct route. 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. See "E. Choosing
Thermostat Locations" on page (8).
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 roof opening. Make sure that at least 15 of the wire extends into the roof opening. See (FIG. 26).
4. Route an indoor temperature sensor (optional)
from the roof opening to the indoor temperature sensor location. The 2 pin connector end goes
F.
to the roof opening. See indoor temperature
sensor installation instructions for proper sensor
location.
8
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 wires to the second unit. Make sure that at least 15 of the 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 that 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.
Choosing Thermostat Locations
1. If the system is to be used WITHOUT an optional 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 thermostat 54 above the floor.
Install the thermostat on a partition, not on an outside wall.
NEVER expose the thermostat 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.
2. If the system is be used WITH an optional indoor temperature sensor, the CCC 2 thermostat may be mounted anywhere in the RV that is convenient. Avoid hard to reach and hard to see areas.

GENERAL INFORMATION
A. Frost Formation On Cooling Coil
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 air inlet hole with the filter removed. If this should occur, inspect the filter 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.
B. Condensation
The manufacturer of this unit will not be responsible for damage caused by condensation forming on ceilings, windows, or other surfaces. Air contains water vapor which condenses when temperature of a surface is below Dew point. During normal operation this unit is designed to remove a certain amount of moisture from the air, depending on the size of the space being conditioned. Keeping doors and windows closed when this air conditioner is in operation will greatly reduce the chance of condensation forming on interior surfaces.
C. Air Distribution
Each A/C unit operating in cool mode, must have a minimum of 2 distribution vents, or the quick cool vent and one vent open, to avoid the risk of freezing coils and improper function.
