automatic management towards 78ºF .
5. Temperature “+”: Each push of this
button corresponds to the increase of
1ºF of temperature.
6. Temperature “-”: Each push of this but-
ton corresponds to the decrease of 1ºF
of temperature.
7. Dispay Window: Dispay temperature,

signal from remote controller by users.
Low-Voltage Protection Function
Settings: Press and hold on “78ºF” button until
screen starts blinking to adjust low-voltage
cutoff value via Temp “+” or “-” button. The
default value is 11.4V, and can range between

REMOTE CONTROL DESCRIPTION
1. ON-OFF: Turns unit on and off
2. Power Mode is used for fast cooling.
3. Eco Mode is used when resting or
reading is preferred.
In Power Mode, the default airflow is the
biggest with the manual adjustment.
In Eco Mode, compressor is running in
low frequency, airflow is defaulted as
smallest with manual adjustment.
Note: Strong recommendation for Power
Mode less than 20 minutes. Long time
operation will significantly shorten the
duration of use.
When cabin temperature is below 30ºC,
Auto Mode is preferred.
In different modes, users can adjust the
air volume according to their needs.
4. Timer: Use Temp “+” or “-” to set the
timer using half hour increments, for up
to 10 hours. Press the timer key again to
cancel the timer.
5. Temp Query: Cycle switching between
ambient temperature and evaporator
surface temperature.
6. Voltage Query: Dispays voltage reading
7. Temp “+”: Temperature Increase
8. Temp “-”: Temperature Decrease
9. Airflow “+”: Increased Air Speed
10. Airflow “-”: Decreased Air Speed
11. Auto Mode: Automatically sets thermo-
stat to 78º
12. Mode: Normal, ECO, Powerful
(The current product status is in the select-
ed heating and ventiation mode, only the
indoor blower works.)
Error Codes and Trouble Shooting
Failure analysis of no cooling or poor effect:
(1) The power cord connected is too long and

Maintenance
In order to ensure the normal operation of
the air conditioner, please pay attention to
the routine maintenance:
(1) When idle for a long time, please remove
the positive and negative power lines
at the battery end. Inspect the sealing
and avoid negative connection direct
to ground, so as to avoid battery dam-
age caused by long-term electrification.
The power line must be connected to
the battery, and it is strictly forbidden
to connect negative direct to ground or
connect to the generator.
(2) Maintainance routine every three months
includes cleaning evaporator and con-
denser, and checking internal and ex-
ternal circuits. The maintenance cycle
should be shortened in special working
conditions, such as dusty and extreme
temperature environments.
(3) It is recommended to power the AC unit
with a battery bank. The use of gen-
erators, soar panels or other external
charging equipment should be used only
for auxilary power.
Discaimers
(1) Nomadic Cooling provides instalation
videos and instalation instructions, but
users must install in accordance with the
videos and instructions. If a user fails to
install in accordance with the instalation
video and instructions provided, errors or
damage and other accidents may occur,
and the user shall bear the responsibil-
ity. The maintenance and material costs
caused by the user shall be paid sepa-
rately, and Nomadic Cooling will not bear
any responsibility.
(2) The user must pay attention to safety
issues during the instalation process.
If personal safety issues occur, the user
must bear the responsibility.
(3) If the user changes the air conditioning
unit in any way, or repaces parts and
components that are not the original, the
user shall bear the responsibility of any
damage to the air equipment and per-
sonal safety. Nomadic Cooling will not
bear any responsibility.
