Purging or evacuating the RecoverXL/XLT is one
of the simplest and most important functions.
Reduce the risk of cross contamination and
prolong the life of the RecoverXL/XLT by purging
after every service.
Note: The purge process must be done before
disconnecting the discharge hose from the
RecoverXL/XLT.
For RecoverXLT Models
1) The Low Pressure Switch will shut the unit
off and the lamp will indicate Recovery
Complete when the unit reaches appropriate
vacuum levels. After the unit shuts down, turn
the system switch to off, then rotate the
selector valve clockwise to OFF to equalize
then to PURGE. Turn the system switch on.
Note: The low side gauge should read an
increase in suction pressure, indicating the
refrigerant that was trapped in the machine.
Wait until the Low Pressure Switch again shuts
the unit off at the appropriate vacuum.
2) Close the valve to the recovery tank and shut
the RecoverXLT off.
For RecoverXL Models
1) Monitor the recovery of the system until the
suction gauge indicates the appropriate level of
vacuum. Turn off and rotate selector valve to
OFF to equalize then to PURGE. After the unit
shuts down, turn the system switch to off, then
rotate the selector valve clockwise to OFF to
equalize then to PURGE. Turn the system
switch on.
2) Turn the system switch on.
Note: The low side gauge should read an
increase in suction pressure, indicating the
refrigerant that was trapped in the machine.
Wait until the suction gauge indicates the
appropriate vacuum.
3) Turn the selector system switch off
4) Close the valve to the recovery tank and shut
the RecoverXL off.

RECOVERY TIPS AND TECHNIQUES
1) To assure the fastest and quickest recovery
possible, use the shortest hoses possible and
avoid hoses with Schrader depressors.
2) Know what kind and the amount of
refrigerant that is going to be recovered. This
is critical to avoid contamination and know
how much refrigerant will be recovered. The
first job of the day usually means a fresh,
empty tank and no cause for worry about over
-filling. However, the last job of the day
means there is already liquid in the tank and
over-filling can be a concern. Over-filling a
recovery cylinder can have disastrous results.
3) Refrigerant responds to heat. Therefore, a
significant increase in the speed of the
recovery process will be obtained if a heat
gun is used, specifically to any spots where
liquid may have accumulated.
4) Always try to recover liquid first. This is the
preferred method of recovery for the
RecoverXL/XLT , which pumps liquid 5 to 7
times faster in standard liquid mode than
vapor.
5) If recovering large amounts of refrigerant (20
lbs or more), the push-pull method is recom-
mended. (Note: This process requires the
hoses to be switched before recovery of the
remaining vapor.)
6) Recovery can often be speeded up by
simultaneous recovery from both the high and
low side of the system. Attach short hoses to
both the high and low side of the system and
join them with a BRUTE™ II Manifold or Y
connector to the hose going to the Suction
Port of the RecoverXL/XLT.
7) Protect the RecoverXL/XLT by keeping the
built-in suction filter IN THE MACHINE.
Failure to use the suction filter in the
RecoverXL/XLT will void the warranty.
8) Recovery machines are not vacuum pumps.
For proper evacuation, use a YELLOW
JACKET SuperEvac™ vacuum pump. To
speed up the evacuation process, use the
SuperEvac vacuum pump and a core removal
tool (Part #18975). For more information
contact your YELLOW JACKET wholesaler.
