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. 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.

INSTALLATION INSTRUCTIONS

A. Precautions

WARNING

!

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 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. When the vent
is removed, it normally creates a 14-1/4" X 14-1/4"
(±1/8") opening.

FIG. 2

1/2 L

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 620515, 620525, 620526, 630515 and 630516 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.

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

FIG. 1

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.

C. Roof Preparation

1. Opening Requirments - Before preparing the ceiling
opening, the type of system options must be de­cided upon. If a remote sensor is to be used,
provision must be made for it. If the load shed option
is to be used, wires must be run from the load shed
control to the Dometic A/C. 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 vent opening will not be used a 14-1/4" x 14­1/4" (±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, 4-conductor control cable, remote
sensor and load shed (Energy Management
System) options as desired.

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.

5. Air Distribution System Installation
a. Dometic Corporation recommends the basic

configuration shown on page 8, 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

These items must be determined in conjunction with the
Air Distribution System and Sizing and Design Require­ments listed in the chart on page7. 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 Requirments

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 fuse 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

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.

c. In a multiple zone installation, this wiring is

required in only one of the 14-1/4" x 14-1/4"
(±1/8") openings.

3. If a Remote Temperature Sensor is used, the con­nector end must be routed to the roof opening of the
system which it will control. Make sure that at least
15" of the sensor cable extends into the roof open­ing. Refer to the Remote Sensor Instructions for
details of the installation. See Section E-1.

4. If a furnace is to be controlled by the system, the two
furnace thermostat leads must be routed to the roof
opening of the air conditioner that will control it.
Make sure that at least 15" of the furnace thermostat
wires extend into the roof opening.

5. 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 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
wires extend into the roof opening.

6. Route a 4-conductor control cable from the Comfort
Control Center™ mounting position into the
14-1/4" x 14-1/4" (±1/8") roof opening. Make sure

opening and 6" extend from the wall at the mounting
position of the Comfort Control Center™. See
Section E-2.

7. In the event that other Air Conditioners are installed
(additional zones) an additional 4-conductor control
cable must be routed to the other Air Conditioners.
Make sure that at least 15" of the wire extends into
the roof opening. See FIG. 31.

8. If an automatic generator start kit (AGS) will be
installed, a 4-conducter control cable must be
routed from the last air conditioner to location of
AGS kit. Follow AGS kit instructions for installation.

E. Dometic Comfort Control Center™ & Cable

Installation

1. Location
a. If the system is to be used WITHOUT a Re-

mote Temperature Sensor, the proper loca­tion of the Comfort Control Center™ is very
important to ensure that it will provide a comfort­able RV temperature. Observe the following
rules when selecting a location:

• Locate the Comfort Control Center™ 54"

above the floor.

• Install the Comfort Control Center™ on a

partition, not on an outside wall.

• NEVER expose it to direct heat from lamps,

sun or other heat producing items.

J. System Configuration, Reset & Checkout

1. Electronic Control Configuration
Depending on the equipment options installed by the
recreational vehicle manufacturer, the appropriate dip
switches will need to be switched to the "ON" position.
See Fig. 29. Placing the switch in the "ON" position

selects that option.
Note: Dip switches are in the "OFF" position when shipped
from the factory except for models supplied with the heat strip
factory installed, (620515). For this model , the #1 dip switch
will be in the "ON" position. To gain access to the dip
switches, the shroud must be removed from the unit. Remove
the four mounting screws around the perimeter of the unit.
Next remove the electrical box cover. (The electrical box will
be on the curb side of the RV after installation.)

c. Heat pump models (630515 or 630516) must

have the red plug of the outdoor ambient sensor
plugged into the RED (P3) plug.

d. Furnace selection - when a furnace has been

connected to a zone, place the furnace dip
switch "ON" for that zone.

e. Differential - differential is the temperature differ-

ence between the "ON/OFF" cycle of the ther­mostat. 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 in the "ON" position.
Note: Setting the Differential dip switch should only be
required when the installation conditions are less than
desirable and is not covered under the limited warranty.

f. STAGE is not used on these units. Leave in the

"OFF" position.

g. Gen start selection - leave in the "OFF" position.
h. Replace the unit electrical box cover.
i. Replace the shroud.
j. Repeat this procedure for each additional zone.

2. System Reset
After setting the dip switches in the electric box, do a
system reset. See FIG. 30.

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 the
