F6-BOOST OPERATION
Direct Liquid or Vapor Recovery
The following are additional safety recommendations when servicing HVAC&R equipment containing refrigerant. This
is the most common method of recovery operation for HVAC&R systems containing less than 20 kg of refrigerant. For
larger systems PUSH-PULL LIQUID RECOVERY method can help speed up the process.
The following are step by step instructions on how to operate the recovery unit in Direct Liquid or Vapor Recovery.
The following is recommended to maximize recovery rates:
A. Use the shortest length of 3/8" ID refrigeration hose on the suction side of the unit.
B. If the refrigerant is clean, remove all suction side filters, screens, etc.
C. Remove all Schrader type valve cores and any valve depressors from the hoses and service valves.
D. Use an evacuated DOT tank.
E. If the unit trips off on High Pressure, change the recovery cylinder.
1. Place a Refrigerant Storage Tank on a scale to determine the current weight of the tank.
DANGER: Make sure the storage tank has enough capacity for the recovery process. See Page 5 for refrigerant
capacity and refrigerant storage tank safety guidelines.
2. Connect refrigerant hoses as shown in diagram below.
3. Turn the OUTLET valve to OPEN. Open Refrigerant Storage tank valve.
4. Turn the RECOVER/PURGE to RECOVER position
5. Plug in the unit into 115v or 230v power source. The Indicator LED will flash GREEN.
6. Push the START button. The Indicator LED will turn solid green. Once the unit' s compressor starts turn the INLET
valve to the OPEN position. If liquid refrigerant is being recovered and a slugging noise is heard, turn the INLET
valve into the LIQUID region until the slugging noise subsides.
Monitor the electronic scale for weight gained during recovery and ensure the tank is not being overfilled. If
approaching tank full conditions, push the Power Switch to OFF position and close tank valve. Replace tank with an
empty one. Push the Power Switch to ON position to resume recovery operation.
7. The unit will automatically shut off after 2 minutes when the INLET pressure drops below 10" hg vac. The Indicator
LED will turn solid YELLOW.
8. Monitor the Inlet gauge for a few minutes, if the pressure rises above 0 PSIG restart the unit by pushing the START
button.
When Recovery is complete, proceed to Purge Procedure.
