DIRECT VAPOR OR LIQUID RECOVERY
CONNECT RECOVERY UNIT (See Diagram 1)
• Use a Refrigerant Manifold (with sight glass) and two spare hoses.
• Connect Ground Strap between Recovery Unit and Recovery Tank (to prevent static electricity
build up).
1. Use a refrigerant manifold (with sight glass) and one spare hose.
2. Connect Manifold between A/C or Refrigeration Unit being serviced and Recovery Unit IN por
3. Connect Refrigerant Hose from Recovery unit OUT port to evacuated DOT Recovery Tank
VAPOR Valve.
4. OPEN VAPOR Valve on DOT Recovery Tank.
5. Keep Manifold Valves CLOSED at this time.
6. On Recovery Unit set Main Power Switch to ON.

Vapor Recovery, if compressor makes slugging or hammering noise, meter incoming liquid
refrigerant by closing LOW Side Manifold Valve until noise subsides.
8. Recovery Unit will run continuously. When desired vacuum level is observed on
Manifold Gauge, close both LOW &
CAUT ION: For Class A2, A2L and A3 recovery, Recovery Unit must be turned off when o Psig
