!
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
GENERAL INFORMATION
A. Product features or specifications as described or illus-
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. Connection to an air distribution system located in
the ceiling/roof cavity of the recreational vehicle.
4. Roof construction with rafters/joists on minimum of
16 inch centers.
5. Minimum of 2.00" and maximum of 5.50" distance
between roof to ceiling of recreational vehicle. Alternate installation methods will allow for roofs more
than 5.50" thick.
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
usage
4. Avoiding the use of heat producing appliances.
A signal word , WARNING OR CAUTION is used
with the safety-alert symbol. They give the level of
risk for potential injury .
WARNING
!
indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury .
CAUTION
!
indicates a potentially hazardous situation which, if not avoided may result in
minor or moderate injury .
CAUTION
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.
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 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.
D. 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.
When sizing the generator, the total power usage of your recreational vehicle must be considered. Keep in mind generators lose power at high altitudes
an dfrom lack of maintenance.
*For wire length over 24 ft., consult the National Electric Code for proper sizing.
**Dometic Corporation gives GENERAL guidelines for generator requirements. These guidelines come from experiences people have had in actual applications.
*** CIRCUIT PROTECTION: Time Delay Fuse or HACR Circuit Breakers Required.
Improper installation may damage equipment,
could endanger life, cause serious injury and/
or property damage.
1. Read Installation and Operating instructions carefully before attempting to start your air conditioner
installation.
2. Dometic Corporation will not be liable for any damages or injury incurred due to failure in following
these instructions.
3. Installation must comply with the National Electrical 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 air
conditioner except those specifically authorized by
Dometic.
5. This equipment must be serviced by qualified personnel and some states require these people to be
licensed.
B. Choosing Proper Location For The Air
Conditioner
This air conditioner is specifically designed for installation on
the roof of a recreational vehicle (RV). When determining
your cooling requirments, 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. When the vent
is removed, it normally creates a 14-1/4" X 14-1/4"
(±1/8") opening.
FIG. 2
L
1/2 L
2/3 L
L
1/3 L
It is preferred that the air conditioner be installed in a relatively
flat and level roof section measured with the RV parked on
a level surface.
Note: A 8° slant to either side, or front to back, is acceptable
for 620615, 620625 & 620626 series.
3. After Location Has Been Selected:
a. Check for obstructions in the area where air
conditioner will be installed. See FIG. 3 & 4.
b. The roof must be designed to support 130
poundswhen the RV is in motion. Normally a
200 lb. static load design will meet this requirement.
CAUTION
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.
c. Check inside the RV for return air cover obstruc-
tions (i.e. door openings, room dividers, curtains, ceiling fixtures, etc.) See FIG. 3 & 4.
FIG. 3

2. Other Locations-When no roof vent is available or
another location is desired, the following is recommended:
a. For one unit installation: The air conditioner
should be mounted slightly forward of center
(front to back) and centered from side to side.
b. For two unit installations: Install one Air Condi-
tioner 1/3 and one Air Conditioner 2/3’s from
front of RV and centered from side to side.
2. Roof Vent Removal
a. Unscrew and remove the roof vent.
b. Remove all caulking compound around open-
ing.

C. Roof Preparation
1. Opening Requirments - Before preparing the ceiling
opening, the type of system options must be decided upon. If a furnace is to be connected, wires
must be run from the furnace to the Dometic A/C.
Read all of the following instructions before beginning the installation.
If a roof roof vent opening will not be used a 14-1/4"
x 14-1/4" (±1/8") opening must be cut through the
roof and ceiling of the RV. This opening must be
located between the roof reinforcing members.
18-1/2"
c. Seal all screw holes and seams where the roof
gasket is located. Use a good grade of all
weather sealant.
d. If the opening exceeds 14-3/8" x 14-3/8", it will
be necessary to install spacers.
e. If the opening is less than 14-1/8" x 14-1/8", it
must be enlarged.
3. New Opening-(Installation Other Than Vent Opening)
a. Mark a 14-1/4" x 14-1/4" (±1/8") square on the
roof and carefully cut the opening.
b. Using the roof opening as a guide, cut the
matching hole in the ceiling.
d. The opening created must be framed to provide
adequate support and prevent air from being
drawn from the roof cavity. Lumber 3/4" or more
in thickness must be used. Remember to provide an entrance hole for power supplies, furnace wiring and a four-conductor control cable.
FIG. 6
There may be electrical wiring between the
roof and the ceiling. Disconnect 115 volt AC
power cord and the positive (+) 12 volt DC terminal at the supply battery. Failure to follow
this instruction may create a shock hazard
causing death or severe personal injury.
The 14-1/4" x 14-1/4" (±1/8") opening is part of the
return air system of the Air Conditioner and must be
finished in accordance with NFPA Standard 501C
Section 2.7.2.

DUCT
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 insu-
lated to prevent condensation from forming on
their surfaces or adjacent surfaces during operation of the air conditioner. This insulation
must be R-7 minimum.
c. Ducts and their joints must be sealed to prevent
condensation from forming on adjacent surfaces during operation of the air conditioner.
e. Return air to the air conditioner must be filtered
to prevent dirt accumulation on air conditioner
cooling surface.
5. Air Distribution System Installation
a. Dometic Corporation recommends the basic
configuration shown on page 16, 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
•Receiver location
These items must be determined in conjunction with the
Air Distribution System and Sizing and Design Requirements listed in the chart on page15. Terminate the start
of the duct at the back edge of the 14-1/4" x 14-1/4" (±1/
8" opening)
Important: Alternate configurations and methods
may be used which still allow the air conditioner to
operate properly; however, these alternate configurations and methods must be approved by the Dometic
Corporation in writing. The following instructions are
based upon the use of Dometic Return Air Kits
3105007.XXX, 3105935.XXX, or 3308120.XXX Genesis
Air Filtration System. The 3107180.006 Bolt/Cover Kit
has the mounting bolts and cover for the AC junction
box for use with these kits.
D.Wiring Requirements
1.Route a copper 12 AWG, with ground, 115 VAC
supply line from the fuse or circuit breaker box to the
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.The power MUST be on a separate 20 Amp time
delay or HACR circuit breaker.
c.Make sure that at least 15" of supply wire
extends into the roof opening. This ensures
easy connection at the junction box.
d.Wiring must comply with all National, State and
Local Wiring Codes.
e.Use a steel sleeve and a grommet or equivalent
methods to protect the wire where it passes into
the opening.
2. Route a dedicated 12 VDC supply line (18 -22 AWG)
from the RV's converter or battery to the roof opening.
a. This supply line must be located in the front
3. If system includes a gas furnace, route two 18 gauge
thermostat wires from the furnace to the 14-1/4" x
14-1/4" (±1/8") roof opening of the air conditioner
that will control it. Make sure that at least 15" of the
wire extends into the roof opening. If more than one
furnace is to be used, route the second set of
thermostat wire to the second air conditioner.
4. Route a 4-conductor control cable from the Re-ceiver 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" extend
from the wall at the mounting position of the Re-
ceiver . See Section E-2.
E. Receiver & Cable Installation
Note: The receiver monitors the temperature of the living
area. The following receiver location is recommended to
maintain the selected temperature setting. Any other location must be approved by Dometic. See FIG.30.
1. Locate the receiver in a front to rear position on the
ceiling, and to one side or the other of the return air
cover. See FIG. 8A, 8B & 8C. Mounting the receiver
from side to side is not recommended, but could be
mounted this way as a last possibility.
Note: When used with the 3308120 Genesis Filtration
System, do not mount the receiver where it will interfere with
the filter removal. See FIG. 8A. When used with the 3105935
Quick Cool Return Air Grille do not install near the discharge
air duct. See FIG. 8C.
Note: To operate the air conditioner, the receiver must be
installed in a location that will allow the remote to be in the
line of sight of the receiver.
a. If another receiver mounting location is antici-
pated, observe the following general rules in
determining the location and submit location to
Dometic for approval.
•Locate the Receiver 54" above the floor.
•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
or directly under cabinets or overhangs
which limit air movement.
•Avoid locations close to supply registers
and the air from them.
•NEVER locate receiver in a room that is
warmer or cooler than the rest of the RV.
•The major living area is normally a good
location.
2. Control Cable Installation
A 4-conductor control cable must be routed from the roof
opening to the Receiver
a. Choose the shortest, most direct route from the
14-1/4" x 14-1/4" (±1/8") opening to the Re-
ceiver location selected. Leave 6" of cable
extending through the wall. See Section D-4.
b. The control cable that should be used is a flat,
4-conductor telephone cable.
