Now you are ready to charge the A/C system. Before charging, check to make sure there are no leaks or
system contaminations by pulling a vacuum on the system. Observe the system for 10 minutes for any loss
of vacuum. We recommend that a minimum of 30-minute vacuum duration be performed to make sure that
there are no leaks or moisture in the system.
IMPORTANT!
IT IS IMPORTANT TO PULL THE VACUUM AT
THIS POINT IN THE INSTALLATION AS IT ALLOWS YOU TO
CONTINUE WITH THE INSTALL WHILE THE SYSTEM CHECKS
FOR LEAKS. THIS IS IMPERATIVE IN KEEPING TO YOUR 4-6
HOUR INSTALL TIME.
●
Once the system has passed the leak test, it is time to charge the
A/C system.
●
Be sure to use R-134a refrigerant.
●
Charge the system by adding 1.85 lbs of R-134a to start, then adjust based on the Ambient Temperature,
High Pressure, and Low Pressure. Do not inject oil into the system on a new install.
●
Do not inject dye into system under any circumstances or at any time
