corresponds to a cycle through 5
different airflow levels.
4. Auto 78ºF: Pressing this button enables
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. Dispay Window: Dispay temperature,
airflow, voltage, error codes and
ambient temperature.
8. Infrared Signal: Acceptance of infrared
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
9-11.5V. Long press on “78 ºF” button again for 5
seconds to set.

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: Dispays 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 ventiation 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
too thin. Poor connection at connector.
(2) No refrigerant or insufficient refrigerant.
(3) Eco mode is used when the temperature
is too high.
(4) Compressor or condensing fan does

power line to the metal or the genera-
tor, reconnect the wirings or harness.
2. Pressure Fault (System leakage) E4.
• Refrigerant leakage or poor
heat dissipation.
3. Sensor Fault E0 or E1.
A. Check whether the plug-in is loose
and re-insert it tightly.
B. Sensor quality problem, repace
the sensor.
4. High current protection F6, or
electronic fan fault F7.
A. Check the condenser heat dissipation,
whether the surface is dirty/blocked.
B. Check whether the terminal or plug-
in of the power line is loose.
C. Check if the plug-in of the fan is loose,
and plug it in again.
D. Condenser fan failure, repace the fan.

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, soar panels or other external
charging equipment should be used only
for auxilary power.
Discaimers
