INSTALLATION STEPS
1. Mark your 14”x 14” rooftop opening. DIY
Kit includes a cardboard tempate. Cut
from the exterior of your vehicle.
Never cover AC unit top fan.
When determining AC unit location,
be sure to allow for the shroud (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 exterior surface.
7. Remove 14”x 14” waterproof gasket
from box.
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 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.
Remove gasket adhesive only after
making any necessary cuts. Pace the
gasket sticky side down.
8. Apply window weld/adhesive around
14”x 14” gasket, after sticking it down on
vehicle roof. DIY kit includes a tube of
polyurethane adhesive seaant.
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 the AC
unit’s mounting bolts.
Do not put adhesive on top of gasket.
Do not damage electrical components
when pacing AC unit.
10. Adhere optional leveling strip behind the
14”x14” gasket. If you do, remove the two
rubber feet at the back of the AC unit.

11. From inside the vehicle add the crossbars
with mounting bolts to securely attach
AC unit to the roof.
A trim ring (included with DIY kit) should be
paced between the vehicle roof and the AC
unit before crossbars are added.
Do not use electric drill on crossbars.
Put the washer/lock washer on each M8 bolt
and hand tighten (+1/4 turn) bolt into the AC
base pate until the crossbars are secure.
Tighten all four of the nuts to the crossbar to
3.7 lbs. of torque (~5 nm).
AC unit will help to create pressure.
When securing AC unit to the vehicle,
increased compression of the gasket
will level the unit against the roof. No
light should be visible.
Do not over-tighten mounting bolts.
Bolts will rotate if over torqued, and
may break from AC base pate.
Over-tightening will void warranty.
Our gaskets are used for vibration
absorption. 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.
AC unit should be resting on foam gasket
and not on the vehicle’s roof.
Over-compression of the AC 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 AC unit.

12. Install and connect LCD control panel
before connecting to power to avoid
blowing internal fuse.
An appropriately-sized fuse must be
paced between your power source
and the AC unit:
48V = 30A fuse
24V = 60A fuse
12V = 125A fuse
An appropriate fuse and fuse holder is
included in the Host or DIY box.
13. 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 for 12V/24V, or
4AWG for 48V AC units.
14. Attach LCD control panel and AC
wiring harnesses.
15. 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.
16. Use the foam separator to properly sepa-
rate hot air from cold air as it enters and
exits the AC unit.
17. Use heat resistant tape to secure the air
separator in pace. Use your best judg-
ment on how much tape to use and
where to adhere it, as every instalation is
different. The tape helps the air separator
keep the warm and cool air separated.

18. Test all connections between the
power source and the unit for excessive
heat during normal operations.
19. Install facepate. Line up the facepate
vents with the air-out fan openings in the
AC base pate. Use the 8 screws to secure
the facepate to the ceiling of your ve-
hicle. The DIY kit screws do not require
pre-drilling into the ceiling, regardless of
finish or material (wood or metal).
The facepate does not screw into the
base of the AC unit. It attaches (flush)
to the vehicle’s ceiling directly.
