Comments regarding leak detector use:
^
Existing R-12 leak detectors currently will not detect R-134a.
^
Many R-134a leak detectors will detect R-12; check with the equipment manufacturer.
^
Always refer to and follow the equipment manufacturers recommendations when operating leak detectors.
Comments regarding weight scale use:
^
If the scale allows electronic control of the flow of refrigerant through the scale, (i.e. internal solenoid valves) be certain that the hose fitting size is
1/2"-16 ACME, and that no refrigerant other than R-134a (along with only specified lubricant) have been used with the scale.
Charging Cylinder
^
The use of a charging cylinder is not recommended because:
^
The refrigerant may be vented into the air from the top valve of cylinder when filling the cylinder with refrigerant.
^
The accuracy of a charging cylinder is generally less than that of an electronic scale or of quality recycle/recharge equipment.
Service Procedures
^
The service procedures for R-134a A/C systems are basically the same as for R-12 A/C systems, however, the following should always be kept in
mind:
