FIRST TIME USE OF THE AC860
1. The AC860 ships from the factory with all internal
components in a vacuum. It should be pre-charged
with refrigerant for optimum performance. The
cylinder mounted in the AC860 is used as the
storage container for recycled refrigerant. This same
refrigerant is then charged to the A/C System during
a charge procedure. This cylinder must be left in the
AC860, as the weight scale is calibrated for this
specific cylinder.
2. Connect the gauge manifold and cylinder of new
refrigerant to the AC860 as shown. See Page 11 for
R134a hose connection to cylinder.
3. Turn Purge Valve on AC860 to OFF. Turn Function Valve on AC860 to RECOVER. Open low
side valve on gauge manifold. Open valve on cylinder of new refrigerant.
4. Connect power cord of AC860 to properly grounded power source. Avoid using an extension
cord. If necessary use a good condition, three wire grounded, #14 AWG or larger extension cord
of the shortest possible length.
5. RTI TECHNOLOGIES and 680/2860 SERIES will display for ten seconds.
6. The display will show the weight of refrigerant in the AC860 cylinder and prompt RECYCLE? The
weight of refrigerant will initially display zero.
7. Press [5] key to begin a recycle procedure. Refrigerant will be drawn from the cylinder of new
refrigerant and stored in the cylinder on the AC860. The weight displayed will begin to increase
after approximately one pound of refrigerant is used to initially fill internal components of the
AC860. Close the valve on the new refrigerant cylinder when the display shows a recommended
2 to 3 pounds. More than this amount can be added to the AC860 cylinder if desired. The
maximum capacity is 24 pounds.
8. When all refrigerant in the hoses and gauge manifold has been recovered, the display will show
RECYCLE COMPLETE CHECK PRESSURES.
9. Press the stop key and turn the Function Valve to OFF.
10. Close the low side valve on the gauge manifold.
11. Disconnect the blue hose from the cylinder of new refrigerant.
DO NOT TURN THE CYLINDER OF NEW REFRIGERANT UP-SIDE-DOWN AS
LIQUID REFRIGERANT WILL BE INTRODUCED INTO THE AC860.
COMPRESSOR DAMAGE COULD RESULT WHICH VOIDS THE WARRANTY.
The above procedure can be used anytime it is necessary
to add new refrigerant to the AC860 cylinder.
