6.3. TOOL FOR REPAIRING REFRIGERATING UNIT HFC-134a
When the fitting for using CFC-12 is connected with the charge pipe (yellow), and then turn the
switch to be using CFC-12, the adaptor can be used for vacuum pumping of CFC-12
refrigerating unit.
Be sure to connect the adaptor with vacuum pump, so that it can be used for both CFC-12 and
HFC-134a.
Since the inside of manifold gauge and charge hoses are vacuum state after vacuum pumping,
the oil of vacuum pumping may flow into HFC-134a refrigerant unit. The adaptor prevents the oil
flowing into the refrigerating unit.
Before running the vacuum pump, connect the charge pipe (yellow) with the fitting for using HFC-
1354a, and then turn the switch to be using HFC-134a.
Conventional repairing devices for CFC-12 can not connect with repairing devices for HFC-
134a. Because of the shape of fitting for HFC-134A (M10 x P1.5 mm) is different from
conventional ones.
