DIRECT VAPOR OR LIQUID RECOVERY OPERA
1.
Connect the unit as shown in
Diagram 1.
2.
Open the vapor valve on the
Recovery Tank.
3.
Open DISCHARGE valve on CR
unit.
4.
Rotate the center valve to the
"RECOVERY" position.
5.
Turn power switch to "ON" position.
6.
Once unit has started, open the
SUCTION valve on the CR unit to start the refrigerant flow.
NOTE: If liquid refrigerant is present, a hammering sound will come from
the compressor. Use the SUCTION valve to meter or regulate the incoming
refrigerant until the hammering sound goes away. The SUCTION gauge
will read the regulated pressure to the compressor.
7.
Monitor the suction gauge until it falls below the required vacuum level.
8.
Rotate the center valve to the SELF-CLEARING position. Again monitor
suction gauge. Once the gauge reads a vacuum, Close SUCTION valve,
turn unit OFF.
RECOVERY AND SELF-CLEARING ARE COMPLETE.
PUSH-PULL LIQUID RECOVERY OPERATION
1.
Connect the unit as shown in
Diagram2.
2.
Open both valves on the Recovery
Tank.
3.
Open DISCHARGE valve on CR
unit.
4.
Rotate the center valve to the
"SELF-CLEARING" position.
5.
Turn power switch "ON" position.
6.
Once unit has started, open the
SUCTION valve on the CR unit to
start the refrigerant flow.
7.
Monitor the optional inline sight glass for liquid refrigerant movement.
8.
Once liquid refrigerant is no longer present, close recovery tank vapor
valve. When the SUCTION gauge falls into a vacuum close SUCTION
valve and turn unit OFF.
PROCEED TO DIRECT VAPOR RECOVERY OPERATION.
