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 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

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
Check if the low voltage protection value is too high

The B-COOL9000 unit comes pre-charged. However, should a leak or
an Incidentoccur during shipping, the following steps must be taken.
Leak Testing
1 - Refrigerant volume (check with level glass)
2 - If volume is low or is lower than the previous check, investigate possible
leak by looking for traces of oil.
3 - Attach the nitrogen tank to the low side port.
4 - Perform a leak test by pressuring the system to 200 psi and then check for leaks
at each fitting and connection and throughout the evaporator and condenser coils.
5 - The system should hold pressure for at least 15 minutes.
6 –Sometimes, but rarely the unit could get damaged during shipping.
7 - If there are no leaks, evacuate the system.
Evacuate System
Evacuate the entire system while meeting local refrigerant handling standards.
We recommend at least 30-45 minutes vacuum before charging.
After the unit is empty, move to charging the system and charge it with 650g of
R134a refrigerant.
Charge the System
The system should be charged by a qualified A/C technician and
follow the guidelines for R134a Freon.

Maintenance
Before beginning cleaning, make sure the air conditioner is
turned off, powered off.
1) Surface Cleaning of inside unit:
Wipe with a clean damp cloth.
The cloth can be dipped in a mild cleaning solution if the unit is very dirty.
2) The core of evaporation chamber is too dirty.
Check for dirt and debris in the evaporator, clean with compressed air
if necessary.
3) Outdoor unit cleaning:
Remove the top cover and clean the condenser with compressed
air. Pay attention not to damage the condenser coil.
4) Long time not in use:
Unplug the air conditioner and wrap the outdoor unit to avoid any
physical damage.
5) Using after long time not in use:
Clean the unit body condenser and evaporation unit. Check for signs of any
foreign matter at the air inlet or outlet of the unit. Check if the drain is
clear; Install remote controller, make inspection and power it on.
Tips:
Maintain the AC unit frequently - at least once every 2 months, If
you operate the AC in a dusty - dirty environment more frequent
cleaning will be required.
Check for blockage on top and bottom of the condenser fan, the
condenser coil and air flow before and after the evaporator
blower.
