Figure 1 Filling the Cylinder
FILLING THE CHARGING CYLINDER
A/C Systems requiring service often do not have a full charge of refrigerant. To avoid unnecessary
repositioning of hoses it is recommended that the TC2670 be filled until about 3 pounds of liquid refrigerant
can be seen in the Charging Cylinder Sight Glasses. The Sight Glasses are visible through slotted openings
on the front of the TC2670.
To fill the TC2670 Charge Cylinder, refer to Figure 1 and follow these steps:
Note: Instructions given for R12 side only. Operation of R134a side is identical.
1. Connect the Low Side Blue Hose to the VAPOR port of a cylinder of the correct refrigerant. An
adapter is provided with the TC2670 for the R134a side which permits the Field Service Coupler to
be attached to the .500-16 ACME fitting on the cylinder of refrigerant (See instruction sheet in
Appendix).
If the cylinder has two ports, observe that the embossed marking on the cylinder knob says VAPOR
or GAS. Do not rely on color coding of the knobs on the valves.
DO NOT CONNECT TO THE LIQUID VALVE.
DO NOT TURN THE CYLINDER UP-SIDE-DOWN.
INTRODUCTION OF LIQUID INTO THE TC2670 MAY DAMAGE THE
COMPRESSOR AND VOID THE WARRANTY.
