RecoverXLT2-AP Operating Guide

Direct Liquid/Vapor Recovery

The RecoverXLT2-AP 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 RecoverXLT2-AP is capable of recov- ering 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 and 45% for HFCs.

Refer to the following instructions and the diagram on page 4:

System Purge Instructions

Purging or evacuating the RecoverXLT2-AP is one

of the simplest and most important functions. Reduce the risk of cross contamination and prolong the life of the RecoverXLT2-AP by purging after every service.

Note: The purge process must be done before disconnecting the discharge hose from the

RecoverXLT2-AP.

1. Once the unit reaches appropriate vacuum level, either at just above ambient pressure with the ambient pressure switch or user defined vacuum

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

level, turn the system switch to OFF, then rotate the selector valve clockwise first to OFF the 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 side gauge reaches an appropriate vacuum.

2. Close the valve to the recovery tank and shut the

RecoverXLT2-AP off.

2) Rotate selector clockwise to the OFF position. Allow pressures to balance.

3) Turn the selector valve counter-clockwise to the previous RECOVER position.

4) Turn the recovery machine ON.

The Push-Pull Liquid Recovery mode is used for transferring large volumes of liquid refrigerant. The RecoverXLT2-AP “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.

• 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 RecoverXLT2-AP as described on page 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. ref

rigerant.

3) A sight glass (Note: Make sure sight

rated for being recovered)

Follow these steps:

Turn off power to the system to be serviced.

2) Hook up the RecoverXLT2-AP, the system to be recovered, and the recovery tank as shown in the diagram on the next page.

3) Purge all hoses of non-condensables before recovering refrigerant into recovery cylinder.

4) Open valves on the recovery tank.

5) Turn the selector valve to VAPOR position. Turn the RecoverXLT2-AP on.

Suction Filter

The RecoverXLT2-AP 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 RecoverXLT2-AP 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
