Troubleshooting - Air conditioners
If any of the following situations occur during the use of air
conditioners, please find out a solution by following the index
If it’s a fault, Please contact the tech. / repair center.
Condition Solution
If the cooling
effect is not good
Select the right mode and set proper temperature and speed.
Check if there is any obstruction at the air inlet and outlet
Check if the surface of the condenser is too dirty
Check if it is short of refrigerant and if the high and low
voltage is within the normal range
There is water on
the surface of
indoor unit
When running in an environment with high humidity, water
drops may form on at the air outlet and core surface, which
is a normal physical phenomenon
Check battery for low voltage and verify the power source is
either DC 12V or 24V
The indoor unit
displays voltage
fault
Check if the low voltage protection value is too high
Check if the sensor at air inlet / outlet is plugged in correctly
The indoor unit
displays sensor
fault
Check if the display temperature is higher than normal
ambient temperature. If it is, change the sensor.
The indoor
unit displays fan
fault
Check if the fan is correctly plugged in. Connect the fan with
a separate 12V or 24V DC power source. If the fan doesn’t
work, replace fan.

The -COOL9000 unit comes pre-charged. However, should a leak or an
Incident occur during shipping, the following steps must be taken.
Leak Testing
1 - Refr gerant volume (check w th level glass)
2 - If volume s low or s lower than the prev ous check, nvest gate poss ble
leak by look ng for traces of o l.
3 - Attach the n trogen tank to the low s de port.
4 - Perform a leak test by pressur ng the system to 200 ps and then check for leaks
at each f tt ng and connect on and throughout the evaporator and condenser co ls.
5 - The system should hold pressure for at least 15 m nutes.
6 - Somet mes, but rarely, the un t could be damaged dur ng sh pp ng.
7 - If there are no leaks, evacuate the system.
Evacuate System
Evacuate the ent re system wh le meet ng local refr gerant handl ng standards.
We recommend at least 30-45 m nutes vacuum before charg ng.
After the un t s empty, move to charg ng the system and charge t w th 650g of
R134a refr gerant.
Charge the System
The system should be charged by a qual f ed A/C techn c an and
follow the gu del nes for R134a Freon.
