Operating Instructions
RECOVERY PROCEDURE
WARNING
Always wear safety goggles when working with refrigerants. Use only
authorized refillable refrigerant tanks. Disconnect hoses with extreme
caution!
All hoses may contain refrigerant under pressure. Read and follow all
warnings at the beginning of this manual before operating the unit.
1. Connect the hoses as described in the Set-Up Instructions.
2. Open the LIQUID and VAPOR valves on the recovery tank.
Open the ball valves on all four hoses.
NOTE: It is necessary to monitor the tank capacity/weight while recovering to prevent
overfilling. During liquid recovery, refrigerant transfers rapidly. Monitor tank weight using
the appropriate weight scale.
3. Look at the system pressure gauge on the unit to be sure there is refrigerant pres-
sure in the system. If there is no pressure, there is no refrigerant to be recovered.
NOTE: By taking the ambient temperature and using a pressure/temperature chart, you
can use this pressure to determine the type of refrigerant in the system.
4. Turn valve on the control panel to RECOVER.
5. Turn switch to RECOVER.
6. Turn the POWER Switch to ON. You wil hear the compressor start.
A float chamber monitors refrigerant being recovered and automatically adjusts the unit to
handle either liquid or vapor refrigerant. This provides for the most efficient recovery. The
amber lights on the control panel indicate the state (LIQUID or VAPOR) of the refriger-
ant currently entering the unit.
7. The blue gauge labeled SYSTEM PRESSURE shows the current system pressure
throughout the recovery process. When the system pressure reaches an adequate
vacuum level, turn the POWER switch to OFF.
The recovery process is complete, but the unit must be cleared before disconnecting all
hoses (see Self-Clearing Procedure).
