RECOVER (RECYCLE)
1. Turn Function Valve on AC2860 to RECOVER.
2. Open high and low valves on gauge manifold.
3. The display will show the weight of refrigerant in the
AC2860 cylinder and indicate the unit is recycling.
4. When the A/C system pressure is in a vacuum the
display will show RECYCLE COMPLETE CHECK
PRESSURES. Wait two minutes to see if the pressure
in the A/C increases (due to liquid refrigerant
vaporizing). The AC2860 will automatically begin
recycling again if the pressure rises above zero.
5. Press the stop key and close the high and low valves on
the gauge manifold.
6. Turn Function Valve on AC2860 to OFF.
Note:
The display will show CYLINDER FULL GO TO CHARGE
if the AC2860 cylinder fills to capacity. Press the STOP key
and perform a charge procedure to transfer refrigerant to
another A/C system or an external storage cylinder.
PURGE AIR - DRAIN OIL
1. The oil drain valve is accessible from the rear of the AC2860, located under the main enclosure.
Slowly open the valve and drain any oil into the measuring cup to determine how much oil (if
any) should be added to the A/C.
2. Leave the oil drain valve open.
3. Measure the room temperature.
4. Find the corresponding pressure for this temperature on the purge chart printed on the AC2860
top panel.
5. Compare this pressure from the chart with that indicated on the Purge Gauge. If the gauge
shows a higher pressure, slowly open the Purge Valve a small amount until the pressure drops
to approximately the pressure shown in the chart.
6. Turn the purge valve to OFF.
7. Close the oil drain valve.
IMPORTANT: Oil must be drained and Air purged after each recover (recycle) procedure.
Failure to do so will cause excess air to be introduced into the A/C during charge and the
AC2860 will fill with air causing a high-pressure shutdown.
