How to Restart the Recovery Machine
● The following procedure is effective to restart the recovery machine after temporary stop during
operation (when the pressure remains in the machine or when the motor is under load at starting).
However if the pressure at discharge side is too high, the unit may not restart. Then cool the
recovery cylinder down or replace the cylinder to spare cylinder which is vacuumed.
＊ The hoses should be connected for
liquid (vapor) recovery.
(See p.12)
① Close the valves of manifold and
system.
② Make the valve of the recovery
machine about one turn clockwise to
set “⓪ START”
③ Turn the valve of recovery machine
slowly clockwise twice and set the
valve to "0 START" position.
④ Set the Power switch to the “ON”
position.
⑤ Push the Start switch.
⑥ If the recovery machine starts, turn
the valve of the recovery machine
slowly to the “② VAPOR RECOVERY” or
the “① LIQUID RECOVERY” position.
How to Recover Different Type of Refrigerant
● Follow this procedure when the different type of refrigerant is recovered.
① Connect the discharge port to a
vacuum pump with a hose.
② Set the valve of the recovery machine
to the “③ PURGE” position.
③ Switch on the vacuum pump.
④ Switch off the vacuum pump after 10
minutes.
⑤ Clean the strainer at the suction port
if necessary.
In Case the Machine Stops During Operation
① Set the Power switch of the recovery machine to the “OFF” position and reset the breaker after
approximately 5 minutes.
② Restart the recovery machine according to “How to Restart the Recovery Machine”.
1）When the recovery machine stopped by a circuit breaker (10A).
① The recovery machine may not start when the temperature of the motor is too high.
② Leave the recovery machine for 10 to 20 minutes as the protector will be reset when the motor is
cooled down.
2）When the recovery machine stopped by a thermal protector.
① Set the Power switch to the “OFF” position.
② Remove the causes of the high pressure.
(Cool down the cylinder by ice and so on when the pressure in the cylinder exceeds 35.7kg/cm2
/507.5psi. Or replace the cylinder with another one.)
③ Restart the recovery machine according to “How to Restart the Recovery Machine”.
① Restart the recovery machine according to “How to Restart the Recovery Machine”.
3）When the High pressure warning lamp was on and the recovery machine stopped.
4）When the Recovery complete switch is on and the recovery machine will not restart.
