1. GENERAL INFORMATION
A. TheGenesisAirFiltrationsSystemisdesignedfor:
1. Installationonarecreationalvehicleatthetimethe
vehicleismanufactured.
2. Mountingofanairconditionerorheatpumponthe
roofofarecreationalvehicle.
3. Roofconstructionwithrafters/joistsonminimumof
16 inch centers.
4. Minimum of 2.00 inches and maximum of 5.50
inches distance between roof to ceiling of recre-
ational vehicle. Alternate installation methods will
allow for roofs more than 5.50 inches thick.
B. Theabilityoftheair conditioner/heat pump to maintain
thedesiredinsidetemperaturedependsontheheatgain
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/heat
pump. Duringextremelyhighoutdoortemperatures,the
heat gain of the vehicle may be reduced by:
1. Parking the RV in a shaded area
2. Usingwindowshades(blindsand/orcurtains)
3. Keepingwindows and doors shutorminimizing
usage
4. Avoidingtheuseofheatproducingappliances
OperationonHighFan/Coolingmodewillgiveoptimum
ormaximumefficiency in highhumidityor high outside
temperature.
Starting the air conditioner/heat pump early in the
morningandgivingita"headstart"ontheexpectedhigh
outdoorambientwill greatly improveitsability to main-
tainthedesiredindoortemperature.
For a more permanent solution to a high heat gain,
accessorieslikeA&Eoutdoorpatioandwindowawnings
willreduceheatgainbyremovingthedirectexposureto
the sun. They also add a nice area to enjoy company
duringthecooloftheevening.
C. Condensation
Note: The manufacturer of this Genesis Air Filtration
System 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
coldsurfaces. WhenairenterstheRV,condensedmoisture
may appear on the ceiling, windows, metal parts, etc. The
airconditioner/heatpumpremovesthismoisturefromtheair
duringnormaloperation. Keepingdoorsandwindowsclosed
whenoperatingtheairconditioner/heatpumpwillminimize
condensedmoisture on cold surfaces.

A. Read Installation and Operating Instructions carefully
before attempting to start your air conditioner installa-
tion.

3. AIR DISTRIBUTION SYSTEM SIZING &
DESIGN
TheInstallerofthisairconditioner/heat pumpsystemmust
designthe air distribution system for his particular applica-
tion.SeveralrequirementsforthissystemMUSTbemetfor
the air conditioner/heat pump to operate properly. These
requirementsareasfollows:
A. Roof cavity thickness must be between 2.00" to 5.50".
This distance is measured between roof and ceiling
surface.
B. Thetotalcross-sectionaldischargeareaofoutletducts
from the plenum area under the air conditioner/heat
pumpmustbeaminimumof16.0sq.incheseachside.
It is the responsibility of the installer of this
air conditioner/heat pump system to ensure
structuralintegrity of the RV roof. Never cre-
ate a low spot on the roof where water will
collect. Water standing around the air con-
ditioner/heat pump may leak into the inte-
rior causing damage to the product and the
RV.

4. AIR DISTRIBUTION SYSTEM
INSTALLATION
Dometic Corporation recommends the basic configuration
showninFIG.1for installingthisairconditioner/heatpump
system. We have found by testing, that this configuration
works best in most applications of this air conditioner/heat
pump system.
ItistheresponsibilityoftheInstallerofthissystemtoreview

A. Duct size
B. Duct layout
C. Registersize
D. Registerlocations
E. Thermostatlocation.

DistributionSystemSizingandDesignRequirementslisted
in Section 3 of this manual.
Important: Alternate configurations and methods
may be used which still allow the air conditioner/heat
pump 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

carefullycuttheopening.
3. Using the roof opening as a guide, cut the matching
hole in the ceiling.
4. The opening created must be framed and sealed to
provideadequatesupportandpreventairfrombeing
drawn from the roof cavity. Lumber 3/4" or more in
thicknessmust be used. Remember to provide an
entranceholeforpowersuppliesandsystemwiresas
needed.
WARNING
!
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 fol-
low this instruction may create a shock haz-
ard causing death or severe personal injury.

H. Install the slider in the return air cover and raise it to the
ceiling template. Route the wires from the return air
cover through the template slot leaving about 3” of wire
in between. Place the front of the return air cover against
the ceiling and slide towards the rear. The flange on the
ceiling template will catch in the groove on the return
cover. Adjust the position (right to left) and install the
front two screws. Start and tighten the remaining screws
to hold it in place. Connect together the DC wires (3
Black - negative and 3 Red - positive) from the supply,
control box and filter indicator. See figure 9.
Note: Number 10 cabinet screw can be used to replace
the two front screws, and pull the plastic return air cover
to the ceiling when the ceiling material is hard.

aged with solar panel option.
I. Tighten the screws holding the return air cover. Slide the

J. Place grill on return air cover and snap in place. Decal is
on end over circuit board.
K. Place slide handle through slots in grill into the slide
posts. Handle will fit in either direction. See Figure 10.
C. The “CLEAN FILTER” bulb will blink as a reminder to
clean/change the air filter every 60 days. If in dusty
conditions, the filter should be checked bi-weekly and
clean/changedifneeded.
1. To clean the filter, remove the dust using a vacuum
cleaner. Wash filter with a mild detergent, rinse with
clean water and allow to dry.
NOTE: Replace filter annually. See your Duo Therm
Dealer for replacement filter. Filter part numbers are
