INSTALLATION STEPS
1. Mark your 14”x 14” rooftop opening.
Cut from the exterior of your vehicle.
Never cover AC top fan.
When determining AC unit location,
be sure to allow for the hood/cover
when positioned on the roof.
Make sure there is no electrical or
other encumbrances in the way.
Do not cut into structural beams.
2. Make sure the panned opening is
centered from all four sides. This gives
the best chance for easy instalation.
Use painter’s tape and a permanent
marker to draw your 14”x 14” cutline.
Make multiple passes with the marker.
If you make a mistake repace the
tape and try again. Measure repeat-
edly to make sure your lines create a
perfect 14”x 14” square.
3. Drill each corner of your markings
through the roof. This will make it easier
to detect the location of your 14”x 14”
opening from the underside of your roof.
Use a 1/8” drill bit for corner holes.
4. Cut on your lines using a jig saw, nibbler
or cutting wheel.
Use a sander or file to smooth out the
rough edges after cutting.

5. Paint around the edges of the cut roof
opening to prevent rust. You can use any
color rust-preventative paint.
6. Remove tape and clean surface.
7. Remove Nomadic Cooling 14”x 14” water-
proof gasket from packaging.
Make sure area/paint is clean, dry and
clear of all debris.
Use alcohol wipes or PrepSol to
remove oil or wax from vehicle roof.
If your AC unit included a premium
gasket, skip to step 8.
If pacing gasket over a high or uneven
roof surface, remove small amounts of the
14”x 14” gasket to match roof contours.
Use bade to cut away gasket
if needed.
Pace the gasket sticky side down.
8. Apply window weld around 14”x 14”
gasket, after sticking it down.
9. Pace AC unit on roof over 14”x 14” gasket
gently. Measure side-to-side until unit is
centered on all four sides.
Be careful not to puncture, rip
or tear the gasket with AC unit’s
mounting bolts.
Do not put adhesive on top of gasket.
Do not damage electrical components
when pacing unit.

10. From inside the vehicle add support
brackets to mounting bolts to attach
AC unit to the roof.
Hand tighten all four bolts then 1/4 turn
more (about 4 lbs. of torque).
Do not use electric drills.
Do not over-tighten mounting bolts.
Bolts will rotate if over torqued, and
may break from base pate.
Over-tightening will void warranty.
If you purchased the optional internal trim
piece, it should be paced between the roof
and the AC unit before brackets are added.
Put the two washers on the M8 bolt and
thread the first nut until crossbar is secured.
Tighten until the gasket is compressed
slightly. No light should be visible.
AC unit will create pressure.
When securing AC unit to the vehicle,
increased compression of the gasket will
level the unit against the roof.
Gasket is used for vibration absorp-
tion. It is very high density and can’t
be compressed more than 10%. Use
gasket tension to control AC unit’s
distance from roof surface.
A/C should be resting on gasket, not vehicle.
Over compression of the unit to the
roof may cause the internal fan to rub
against the fan housing.
Be sure the fan bades rotate freely
prior to starting the unit.

11. Connect DC power wires to unit. “Quick
Connection to DC Wiring Harness” included.
Make sure wiring is appropriately
sized and is no smaller than 2AWG.
Make sure the fuse is installed and
appropriately sized.
Install and connect LCD panel before
connecting to power to avoid blow-
ing internal fuse! A 125A fuse/breaker
is mandatory between your power
source and the air conditioning unit.
12. Attach LCD control panel and AC
wiring harnesses.
13. Attach thermostat wires to control panel
wiring harness.
For details of control panel connections,
refer to electrical wiring diagram on page 12.
Condenser is always to the left of the
back wire. Be careful not to break
these wires.
14. Use the foam separator (Option A or B)
to properly separate hot air from cold air
as it enters and exits the AC unit.
OPTION A
For deeper roofs, you
can double the foam
separators by
stacking them
on each other.
OPTION B

15. Test all connections between the
power source and the unit for excessive
heat during normal operations.
16. Install facepate. Use self-drilling screws
to firmly secure your facepate to your
final roof panel/wall.
