Recovery should always be performed in well ventilated areas. Use the RecoverXL/XLT only in locations where mechanical ventilation which provides at least four air changes per hour is present, or place the unit 18” above the floor during use.
The RecoverXL/XLT should not be used near open containers of gasoline or any other flammable liquid. Do not allow refrigerants to come in contact with open flame. Refrigerant decomposition in flame results in phosgene gas. Breathing phosgene gas can be fatal.

RecoverXL Operating Guide
Direct Liquid/Vapor Recovery
The RecoverXL is used to pull liquid or vapor refrigerant out of the system and transfer it into a recovery cylinder.
Liquid recovery is accomplished by connecting to the high pressure system discharge service port (liquid port) side of the system being serviced with a manifold (to regulate refrigerant flow).
Vapor recovery can be done by connecting to the system suction service port (low pressure) side of the system.
Because the RecoverXL is capable of recovering liquid, it is more efficient to recover all of the liquid, followed by the vapor.
Ensure you have the capacity to recover all the re­frigerant in the system. In the USA the recovery cylinders can only be filled to 80% capacity and in the EU it is only 60% capacity.
Refer to the following instructions and the diagram on page 4:

The RecoverXLT is used to pull liquid or vapor refrigerant directly out of the system and transfer it into a recovery cylinder.

Vapor recovery can be done by connecting to the system suction service port (low pressure) side of the system.

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 push­pull 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
rigerant.
ref
 System is a heat pump or other unit with a
reversing valve.
 System has an accumulator between the
service ports used in liquid recovery.
 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. rigerant.

Auto Purge Instructions
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.

Note: The low side gauge should read an increase in suction pressure, indicating the refrigerant that was trapped in the machine.

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 am refrigerant that is g is critical to avoid contamination and
uch refrigerant will be recovered.
how m
st job of the day usually means a fresh,
fir 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 RecoverXL/XLT , which pumps liquid 5 to 7
es faster in standard liquid mode than

Suction Filter
The RecoverXL/XLT is equipped with a built-in particulate strainer located behind the suction port. Unscrew the suction port by using a 11/16 wrench to unscrew the hex head port to remove. This prevents contaminants, copper shavings, carbon, and other foreign objects from making their way to the RecoverXL/XLT compressor and causing permanent damage.
Like a filter drier, this strainer MUST be cleaned or replaced often. Failure to do this can cause the strainer to become too clogged for refrigerant to flow freely. A sure sign that the straining device is
clogged is the freezing of the suction port and the filter cover.
Before replacing, check the condition of the o-ring. Replace if necessary.
Note: Make sure to use a strainer in the RecoverXL/XLT for every job! Filter strainers and o-rings are available from your supplier.
