OPERATION
The following are step by step instructions on how to operate the recovery unit in
Direct Liquid or Vapor Recovery.
VAPOR RECOVERY
1.
Place a Refrigerant Storage Tank on a scale to determine the current weight of the
tank.
DANGER: Make sure the recovery tank has enough capacity for the recovery process.
See page 5 for tank refrigerant capacity calculations and additional tank safety
guidelines.
2.
Connect unit into the oil extraction closed loop. Example diagram shown below.
WARNING: The unit must be protected against entry of residual oil and resins.
Hardened
oil and resins will damage the piston seal and
interfere
with the compressor suction and
discharge valve seats. Warranty may
be void if oil and resins are present.

Once it is determine the unit is to begin the recover process, push the START/STOP
button. The Indicator LED will turn solid green. The unit is now recovering gas from
the closed loop system.
Monitor the electronic scale for weight gained during recovery and ensure the tank is
not being overfilled. If approaching tank full conditions, push the START/STOP button
to turn off the unit. Replace tank with an empty one. Push the START/STOP button to
