to vapor port as shown in diagram on page 4.
4. Connect the Utility port of your manifold to the
1/4" SUCTION port of the RecoverXLT.
5. Connect one hose from the recovery cylinder
(liquid side) to the 1/4" DISCHARGE port of
the RecoverXLT.
Note: Be sure to connect hose ends with
shut-off to suction and discharge ports of
recovery machine (for best performance use
3/8" hoses.)
6. Purge all hoses of non-condensables before
recovering refrigerant into recovery cylinder.
7. Open the liquid valve on the recovery tank.
8. Turn the RecoverXLT on.
9. Turn the selector VALVE on the RecoverXLT to
either the LIQUID or VAPOR position.
10. Open the Utility and either High Side or Low
Side valves on the manifold. Remember it is
more efficient to recover the liquid refrigerant
Restart Procedure
If the recovery unit was stopped during operation,
it may be necessary to balance the internal
pressures before the unit will start.
To balance the internal pressure:
1) Turn the system switch off.
Push-Pull Liquid Recovery
The Push-Pull Liquid Recovery mode is used for
transferring large volumes of liquid refrigerant.
The RecoverXL/XLT "pulls" vapor from the
recovery cylinder and produces high pressure
discharge gas that "pushes" liquid out of the
HVAC system and into the recovery cylinder. The
auto purge feature makes the reconfiguration to
vapor recovery easier and faster to do.
Some HVAC systems will not allow for the push-
pull recovery method. If any of the following
conditions apply, do not use push-pull method, but
follow the instructions on page 3 for the
RecoverXL and page 4 for RecoverXLT.

System contains less than 10 pounds of
refrigerant.

System is a heat pump or other unit with a
reversing valve.

System has an accumulator between the
service ports used in liquid recovery.
first. Caution: do not over-pressure low side
gauge.
11. The RecoverXLT will continue to recover until
it reaches and sustains the appropriate vacuum
at which point the LOW PRESSURE SWITCH
shuts down the unit and the lamp indicates
Recovery Complete.
12. Turn the system switch off. Turn the selector
valve clockwise to OFF. Turn the system switch
on. Turn selector valve to PURGE position.
13. When the unit again shuts down and the lamp
indicates Recovery Complete, the recovery and
purge cycles are complete.
Note: If the machine is not recovering, refer to
the troubleshooting guide on page 9. Restart
procedures are on the side of the machine and
below.
2) Rotate selector clockwise to the OFF position.
Allow pressures to balance.
3) Turn the recovery machine ON.
4) Turn the selector valve counter-clockwise to
the previous RECOVER position.

The refrigerant system does not allow for the
formation of a solid column of liquid.
For push-pull recovery, a sight glass is monitored
during recovery. When liquid is no longer visible,
stop recovery and finish recovering using the
VAPOR recovery process for RecoverXL or
RecoverXLT as described on page 3 or 4.
When push-pull recovery is complete, a small
amount of refrigerant remains in the system. For
complete recovery, the system must be pulled into
a vacuum as required by EPA standards. This
process requires:
1) An extra hose for the push-pull recovery.
2) A recovery cylinder with about 5 lbs. of
refrigerant.
3) A sight glass (Note: Make sure sight glass is
rated for the pressure of the refrigerant
being recovered).
