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 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.
