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 AC800 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 AC800.
To fill the AC800 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 short Yellow Hose provided to the Rear Port of the AC800 and to the VAPOR port
of a cylinder of the correct refrigerant.
DO NOT CONNECT TO THE LIQUID VALVE.
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 TURN THE CYLINDER UP-SIDE-DOWN.
INTRODUCTION OF LIQUID INTO THE AC800 MAY DAMAGE THE
COMPRESSOR AND VOID THE WARRANTY.
