INSTALLATION STEPS

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.

Make sure the planned opening is centered from all four sides. This gives the best chance for easy installation.

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 thetape and try again. Measure repeatedly to make sure your lines create a perfect 14”x 14” square.

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.

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

Paint around the edges of the cut roof opening to prevent rust. You can use any color rust-preventative paint.

Remove tape and clean surface.
Remove Nomadic Cooling 14”x 14” waterproof 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 9.

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.

Apply window weld around 14”x 14” gasket, after sticking it down.

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. Do not put adhesive on top of gasket. Do not damage electrical components when placing unit.

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.

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 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

Over compression of the unit to the roof may cause the internal fan to rub against the fan housing. Be sure the fan blades rotate freely prior to starting the unit.

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 blowing internal fuse! A 125A fuse/breaker is mandatory between your power source and the air conditioning unit.

Attach LCD control panel and AC wiring harnesses.

Attach thermostat wires to control panel wiring harness. Condenser is always to the left of the black wire. Be careful not to break these wires. See electrical wiring diagram on page 12.

Use the foam separator (Option A or B) to properly separate hot air from cold air as it enters and exits the AC unit.

For deeper roofs, you can double the foam separators by stacking them on each other.

Test all connections between thepower source and the unit for excessive heat during normal operations.

Install faceplate. Use self-drilling screws to firmly secure your faceplate to your final roof panel/wall.
