Nomadic Cooling 3000 Directions

Updated: Nov 24, 2020


Instillation time 1-2 hours.

Its not mandatory but its a good idea to mark your 14x14 rooftop opening from inside your vehicle to make sure there is no electrical or other encumbrances in the way.


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


Tip: Use a Sharpie.

Tip: Use painters tape under the Sharpie.

Tip: Measure repeatedly to make sure design is 14x14 square.


Drill each corner of your markings from inside your rig through the roof upwords. This will make it easy to mark your 14x14 opening from the underside of your roof to the outside of your roof.

  • 1/8 inch drill

Connect the dots that you just drilled in your roof to make a perfect 14x14 opening. Cut on the line.


Tip: Make your mark on painters tape. If you make a mistake replace tape, and try again.


Tip: Measure repeatedly to make sure design is 14x14 square.



Tip: Use a file to smooth out the rough edges after cutting the 14x14 opening.

Rough edges are not recommended for a waterproof seal.


Tip: Paint the newly cut roof to prevent rust.

Remove tape and clean surface.

Caution: Do not harm electrical components when placing unit.


From inside the vehicle add support brackets to mounting bolts to attach unit to the roof.



Tighten Bolts x 4


Do not over-tighten mounting nuts. Bolts will rotate if over torqued.


Overtightening

***WILL BREAK BOLT FROM BASE PAN**


Tip: keep an eye on the foam gasket. Over-tightening will reduce effectiveness of the waterproofing seal.


Tip: Use bracket tension to compress foam gasket to create the desired surface level on roof exterior.


When securing unit to the vehicle increased compression of the gasket will level the unit against the roof.


Tip: Use gasket tension to control ac units distance from roof surface.


AC should be resting on gasket not vehicle.


Tip: Over compression of the unit to the roof may cause the fan to rub agains the fan housing. Make sure the fan blades rotates freely prior to starting the unit.


Connect DC power wires to unit. Quick Connection to DC wiring harness included.


Tip: Make sure wiring is appropriately sized.


Tip: Make sure fuse is installed and appropriately sized.





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