The B-COOL9000 unit comes pre-charged. However, should a leak or an
Incident occur 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 be 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.
