INSTALLATION STEPS
1. Mark your 14”x 14” rooftop opening. DIY
Kit includes a cardboard tempate. 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 panned opening is
centered from all four sides. This gives
the best chance for easy instalation.
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 repace 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 pacing gasket over a high or uneven
roof surface, remove small amounts of the
14”x 14” gasket to match roof contours.
Use bade to cut away gasket
if needed.
Remove gasket adhesive only after
making any necessary cuts. Pace 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 seaant.
9. Pace 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 pacing 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
paced 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 pate 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 pate.
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 bades rotate freely
prior to starting the AC unit.
