PRESSURIZED containers or overfilled containers may cause violent explosions and possible injury or
death. Use only D.O.T. approved refillable refrigerant containers. Federal regulations require refrigerants
to be transported in containers meeting D.O.T. specs 4BW or 4BA.
HOSES may contain refrigerant under pressure. Contact with refrigerant may cause injury. Wear
protective equipment. Disconnect hoses with extreme caution.
HIGH VOLTAGE electricity is present inside cabinet. Disconnect power before servicing.
USE only with refrigerants 12, 22, 500, 502, 134a 410a and blends with similar pressures.
THIS equipment is for use by qualified and trained personnel only. Operators must be familiar with
refrigerants and the dangers of pressurized containers.
HELPFUL HINTS
· Always close inlet (V1) before closing discharge (V3).
· If unit starts to “chug”, throttle down inlet (V1).
· If discharge pressure starts to rise, subcool the recovery tank.
· Never turn the recover/self-evac (V2) while unit is running.
· Always purge your hoses and recovery tank of non-condensables.
· Always use an inlet filter (part # ALF-032).
· Always weigh your recovery tank with a scale while using the test plug.
· Maintain an inlet pressure below 90 psig. during long-term vapor recovery.
· While subcooling, maintain 100-200 psi higher discharge pressure than the
recovery tank’s pressure.
