GENERAL INFORMATION
A. Productfeaturesorspecificationsasdescribedorillus-
trated are subject to change without notice.
B. This air conditioner is designed for:
1. Installationonarecreationalvehicleduringthetime
thevehicleismanufactured.
2. Mountingontheroofofarecreationalvehicle.
3. Connection to an air distribution system located in
theceiling/roofcavityoftherecreationalvehicle.
4. Roofconstructionwithrafters/joistsonminimumof
16 inch centers.
5. Minimum of 2.00" and maximum of 5.50" distance
betweenrooftoceilingofrecreationalvehicle.Alter-
nate installation methods will allow for roofs more
than 5.50" thick.
C. Theabilityoftheairconditionertomaintainthedesired
insidetemperaturedependsontheheatgainoftheRV.
Somepreventativemeasurestakenbytheoccupantsof
the RV can reduce the heat gain and improve the
performanceoftheairconditioner.Duringextremelyhigh
outdoortemperatures,theheatgainofthevehiclemay
bereducedby:
1. Parking the RV in a shaded area
2. Usingwindowshades(blindsand/orcurtains)
3. Keeping windows and doors shut or minimizing
usage
4. Avoidingtheuseofheatproducingappliances.
Operation on High Fan/Cooling mode will give optimum or
maximum efficiency in high humidity or high outside tem-
peratures.
Startingtheairconditionerearlyinthemorningandgivingit
a "head start" on the expected high outdoor ambient will
greatly improve its ability to maintain the desired indoor
temperature.
Fora morepermanentsolution tohighheat gain,accesso-
rieslikeA&Eoutdoorpatioandwindowawningswillreduce
heat gain by removing the direct sun. They also add a nice
areato enjoycompanyduring thecool oftheevening.
D. Condensation
Note: The manufacturer of this air conditioner will not be
responsiblefordamagecausedbycondensedmoistureon
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 re-
moves this moisture from the air during normal operation.
Keepingdoorsandwindowsclosedwhenthisairconditioner
is in operation will minimize condensed moisture on cold
surfaces.

2. DometicCorporationwillnotbeliableforany dam-
ages or injury incurred due to failure in following
these instructions.
3. Installation must comply with the National Electri-

B. Choosing Proper Location For The Air
Conditioner
Thisairconditionerisspecificallydesignedforinstallationon
the roof of a recreational vehicle (RV). When determining
your cooling requirments, the following should be consid-
ered:
•Size of RV;
•Windowarea(increasesheatgain);
•Amountof insulation inwalls and roof;
•Geographicallocation wheretheRV willbeused;
•Personalcomfortlevelrequired.
1. NormalLocation-Theairconditionerisdesignedto
fitoveranexistingroofventopening.Whenthevent
isremoved,itnormallycreatesa14-1/4"X14-1/4"
(±1/8")opening.
2. OtherLocations-When no roofvent is availableor
anotherlocationisdesired,thefollowingisrecom-
mended:
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. Fortwounitinstallations:InstalloneAirCondi-
tioner 1/3 and one Air Conditioner 2/3’s from
front of RV and centered from side to side.

It is the responsibility of the installer of this
air conditioner system to ensure structural in-
tegrity 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 prod-
uct and the RV.

3. AfterLocation HasBeen 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

ment.

C. Roof Preparation
1. OpeningRequirments-Beforepreparingtheceiling
opening, the type of system options must be de-
cided upon. If a furnace is to be connected, wires
must be run from the furnace to the Dometic A/C.
Readall ofthe followinginstructions beforebegin-
ning the installation.
Ifaroofroofventopeningwillnotbeuseda14-1/4"
x 14-1/4" (±1/8") opening must be cut through the
roof and ceiling of the RV. This opening must be
locatedbetweentheroofreinforcingmembers.
There may be electrical wiring between the
roof and the ceiling. Disconnect 115 volt AC
power cord and the positive (+) 12 volt DC ter-
minal at the supply battery. Failure to follow
this instruction may create a shock hazard
causing death or severe personal injury.
The14-1/4"x14-1/4"(±1/8")openingispart ofthe
returnairsystemoftheAirConditionerandmustbe
finished in accordance with NFPA Standard 501C

SeveralrequirementsforthissystemMUSTbemetfor
the air conditioner to operate properly. These require-
ments are as follows:
a. The duct material must meet or exceed any
agencyorRVIAStandardthatmaybeinexist-
ence at the time the RV is produced.
b. All discharge air ducts must be properly insu-
latedtopreventcondensationfromformingon
their surfaces or adjacent surfaces during op-
eration of the air conditioner. This insulation
must be R-7 minimum.
c. Ductsandtheirjointsmustbesealedtoprevent

Important: Alternate configurations and methods
may be used which still allow the air conditioner to
operate properly; however, these alternate configura-
tions 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
supplylinefromthefuseorcircuitbreakerboxtothe

portionofthe14-1/4"x14-1/4"(±1/8")opening.
b. ThepowerMUSTbeonaseparate20Amptime

c. Make sure that at least 15" of supply wire
extends into the roof opening. This ensures
easy connection at the junction box.
d. WiringmustcomplywithallNational,Stateand
LocalWiringCodes.
e. Useasteelsleeveandagrommetorequivalent

CAUTION
It is the responsibility of the installer of this
air conditioner system to ensure structural in-
tegrity of the RV roof. Never create a low spot
on the roof where water will collect. Water
standing around the air conditioner may leak
