The purpose of the Recovery & Recycling mode is to recover
refrigerant from the air conditioning system, which will
condense, purify and store the liquid refrigerant in the unit
cylinder ready for re-use.
To initiate the Recovery mode, press the 'UP' key once, followed by 'START' on the console.
Display shows (- - - -). Now, there are two choices:
1. Press "START" key again to recover the whole amount of the refrigerant from the A/C system
or storage cylinder.
2. With "UP" or "DOWN" key to select desired quantity of refrigerant to be recovered from the a/c
system or storage cylinder. After the quantity selection, press "START" key.
Note: Open the hand valves (4) on the console to allow the flow of the refrigerant from the
a/c system into the unit before making the above selection.
During the recovery process, the Recovery mode indicator will now be ON and the display (2) will
indicate the amount of refrigerant being recovered.
In normal operation the above condition will be maintained until a vacuum of -0.4 bar (15 In Hg) is
reached at either the discharge or suction ports. When this occurs, the machine will beep once,
and the unit will enter the recovery "PAUSE" mode. In this mode, the unit will shut down the
recovery function and pause for 3 min., which during this time the recovery mode indicator will be
ON constantly. The display (2) will indicate "PAUSE". During this function, the unit is monitoring
whether the air-conditioning system pressure is increasing, due to any refrigerant that may be left
in the accumulator or dryer. If the pressure increases above zero, the machine will re-start the
recovery function automatically and recover the rest of the remaining refrigerant.
