INSTALLATION STEPS
1. The NC-X2 is designed to fit an industry
standard 14"x14" opening. If you need to
cut a rooftop opening, mark the interi-
or ceiling using the cardboard tempate
provided in the host box.
Never cover AC top fan. Do not cut
into structural beams.
When determining AC unit location,
be sure to allow for the 22.5" x 28"
shroud when positioned on the roof.
Make sure there are no electrical or
other encumbrances in the way.
2. Make sure the panned opening is
centered from all four sides. This gives
the best chance for easy instalation.
Center the opening between the ribs of the
interior ceiling.
Using the 14"x14" tempate provided, mark
the four corners with a permanent marker.
3. Drill each corner of your markings
through the interior roof using a 1/8” bit.
On the exterior rooftop, use painter’s
tape and a permanent marker to draw
your 14"x14" cutlines from hole to
hole. Make multiple passes with the
permanent marker.
If you make a mistake repace the
tape and try again. Measure repeat-
edly to make sure your lines create a
perfect 14"x14" square.
4. Cut on your lines on the rooftop 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 surface.
7. Remove 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"x14" 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 polyurethane adhesive seaant (in-
cluded in DIY kit) around 14"x14" gasket.
9. Gently pace AC unit on roof over gasket.
Inner gasket dimension is 14"x14", outer
dimension is 16.25"x16.25". Measure side-
to-side until 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 pacing AC unit.
10. Adhere optional leveling strip behind the
foam gasket.

11. From inside the vehicle add the crossbars
to attach AC unit to the roof. Locate the
mounting bolts, washers and nuts.
Do not use electric drill on crossbars.
12. If possible with your particuar build, we
recommend using a trim ring to provide ad-
ditional support around the rooftop open-
ing. The DIY kit includes a Nomadic Cooling
X2trim ring. Professional upfitters typically
create their own custom trim rings.
13. Add the nut, washer and lock washer to
each of the four bolts that screw into the AC
unit base pate through the crossbar.
Hand-tighten all four bolts to the AC unit.
Do not over tighten! Once all four bolts are
hand-tight, torque the lock nuts to 3.7 lb to
secure the crossbars to the AC unit, and the
AC unit to the roof.
With optional Trim Ring:
If NOT using a trim ring, you may use
the optional pastic spacer for the two
rear bolts, between the crossbars and
the AC unit base.
Without Trim Ring showing optional spacer:
During the instalation process, if the
locking nut is installed too tightly, it
may cause deformation of the AC unit
base pate. The spacer can pay a limit-
ing role, with any excess locking force
acting on the spacer instead of the AC
unit base pate.
A sticker found on the bag
of bolts may say to tighten
to 5.0 lbs. of torque, please
disregard and use the rec-
ommended 3.7 lbs.
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 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 unit.
12. Install and connect LCD control panel
before connecting to power to avoid
blowing internal fuse.
An appropriately-sized fuse must be
paced between your power source
and the AC unit:
48V = 30A fuse
24V = 50A fuse
12V = 70A fuse
13. Connect DC power wires to unit. “Quick
Connection to DC Wiring Harness” included.
12V systems use an Anderson connector,
24V and 48V systems use a simiar Ander-
son style connector.
Make sure wiring is appropriately
sized and is no smaller than 4AWG.
14. Attach LCD control panel and AC
wiring harnesses.
15. Attach thermostat wires to control panel
wiring harness.
Details of control panel connections are
shown in electrical diagram on page 12.
Condenser is always to the left of the
back 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.
