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.
