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 tempate
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 panned opening is
centered from all four sides. This gives
the best chance for easy instalation.
Center the opening between the ribs of the
interior ceiling.
Using the 14"x14" tempate 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 repace 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 pacing gasket over a high or uneven
roof surface, remove small amounts of the
14"x14" gasket to match roof contours.
Use bade to cut away gasket
if needed.
Remove gasket adhesive only after
making any necessary cuts. Pace the
gasket sticky side down.
8. Apply polyurethane adhesive seaant (in-
cluded in DIY kit) around 14"x14" gasket.
9. Gently pace 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 pacing 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 particuar 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 pate 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 pastic spacer for the two
rear bolts, between the crossbars and
the AC unit base.
Without Trim Ring showing optional spacer:
During the instalation process, if the
locking nut is installed too tightly, it
may cause deformation of the AC unit
base pate. The spacer can pay a limit-
ing role, with any excess locking force
acting on the spacer instead of the AC
unit base pate.
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 pate.
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 bades 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
paced 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 simiar 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
back 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.

17. Use heat resistant tape to secure the air
separator in pace. Use your best judg-
ment on how much tape to use and
where to adhere it, as every instalation is
different. The tape helps the air separator
keep the warm and cool air separated.
18. Test all connections between the
power source and the unit for excessive
heat during normal operations.
19. Install facepate. Line up the facepate
vents with the air-out fan openings in the
AC base pate. Use 8 screws (back screws
were included in instalation kit) that will
match your vehicle interior to secure the
facepate to the ceiling.
The facepate does not screw into the
AC unit base. It attaches (flush mount-
ed) to the vehicle’s ceiling directly.
Congratulations!

Troubleshoot Common Issues
All of our AC units are bench tested before
leaving the Nomadic Cooling warehouse. In
the unfortunate event that your AC unit is
not working properly, you should consider
some of these more common problems that
our technical support team encounter.
1. Power issues. Using a voltmeter, measure
the voltage the AC unit is receiving from
the power source. A drop in expected
power will cause a drop in cooling capac-
ity for the AC unit, just as it would cause
a light bulb to not glow as brightly.
A. If the voltage getting to the AC unit is
low, the first thing to consider is the dis-
tance from the power source to the AC
unit. Voltage loss in wires increases as the
distance grows. Our AC unit power cord
specifications are conservative, but if the
distance is greater than 15-20 feet, it may
be necessary to use a thicker gauge wire.
If the wiring distance is not an issue, you can
check the following:
B. Check the fuse or breaker, and any other
inline components between your power
source and the AC unit. Check the wiring
connections to and from these compo-
nents. Ensure that your fuse or breaker
are properly set, inspect the wiring in and
around such components for any cracks
or looseness.
C. Check the wires from your power source
to your AC unit. While running these
wires through a vehicle’s framework,
it can be necessary to twist and wrap
around obstacles, or feed them through
narrow spaces, often with sharp edges
exposed. This can result in damage to
the wires or insuation, which will cause a
grounding or short, and a drop in amper-
age to the AC unit.
2. Are the Crossbar Bolts are too long for
your build? Every build is different, and
if you find that the crossbar bolts are too
long, you can use a cold saw, bandsaw,
grinder or hacksaw to trim them down to
the length you need.
Remember to wear safety goggles!
Thread the nut before cutting the bolt
and then use it to re-form the thread
after cutting.
If you need to contact technical support...
Every system is different, so it is extremely
helpful (if not necessary) for our support
team to have photos of your setup to help
troubleshoot a problem. Please be prepared
to take any requested photos and send
them to suppor[email protected].
You can initiate support requests by sending
an e-mail to suppor[email protected].
Or you can call [phone]. Our support
team attempts to respond as soon as possi-
ble and we strive to always respond within
24 hours Monday through Friday.
