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 planned opening is centered from all four sides . This gives the best chance for easy installation . Vehicle Front
14″

14″

14″
Exterior Roof

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 replace the tape and try again . Measure repeatedly 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 .
Exterior 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 .

If placing gasket over a high or uneven roof surface, remove small amounts of the 14″x 14″ gasket to match roof contours .
Use blade to cut away gasket if needed .

Place the gasket sticky side down .

Exterior Roof
6. Remove tape and clean surface .
7. Remove Nomadic Cooling 14″x 14″ waterproof gasket from packaging .

8. Apply window weld around 14″x 14″ gasket, after sticking it down .
CUTAWAYS FOR ROOF RIDGES Exterior Roof

URETHANE ADHESIVE

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 9 .
High compression foam Low compression foam

9. Place 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 .

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 plate . Over-tightening will void warranty . If you purchased the optional internal trim piece, it should be placed between the roof and the AC unit before brackets are added .

Brackets

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 .

Flat side up

1. Tighten until flush with crossbar.
2. Hand tighten, then 1/4 turn more.

When securing AC unit to the vehicle, increased compression of the gasket will level the unit against the roof .
Gasket is 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 .
A/C should be resting on gasket, not vehicle .
