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
bereduced by:
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.
Foramorepermanentsolution to high heat gain,accesso-
rieslikeA&Eoutdoorpatioandwindowawningswillreduce
heat gain by removing the direct sun. They also add a nice
areatoenjoycompany during the coolof theevening.
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.

B. Choosing Proper Location For The Air
Conditioner
Thisairconditionerisspecificallydesignedforinstallationon
the roof of a recreational vehicle (RV). When determining
yourcoolingrequirements,thefollowingshouldbeconsid-
ered:
•Size of RV;
•Windowarea(increasesheatgain);
•Amountof insulationin walls androof;
•GeographicallocationwheretheRV will be used;
•Personalcomfortlevelrequired.
1. NormalLocation-Theairconditionerisdesignedto
fitoveranexistingroofventopening.Whenthevent
isremoved,itnormallycreatesa14-1/4"X14-1/4"
(±1/8")opening.
2. OtherLocations-When no roof vent isavailable or
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.

FIG. 2
3. AfterLocation Has BeenSelected:
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
200lb.staticloaddesignwillmeetthisrequire-
ment.
c. CheckinsidetheRVforreturnaircoverobstruc-
tions (i.e. door openings, room dividers, cur-
tains, ceiling fixtures, etc.) See FIG. 3 & 4.
FIG. 1 Roof Vent
Opening
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.

b. All discharge air ducts must be properly insu-
latedtopreventcondensationfromformingon

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.
