HOW TO USE
3）Recovery procedure
● Recover from the high pressure side of the system in case of liquid recovery and recover from the
low pressure side in case of vapor recovery.
● Recover from the high pressure side (liquid refrigerant) when a large volume of refrigerant (5kg
or more) is recovered in one time.
◆ Refrigerant inside the system, which is unsure if it is liquid or vapor, to be liquid
recovered with the valve adjusted to “① Liquid recovery” with less suction pressure.
◆ Throttle the valve of the manifold to regulate the suction pressure to approximately
3kg/cm
2
/43.5psi when the pressure in the system is very high in summer or during
vapor recovery.
◆ Use an oil separator when refrigerant with a large amount of oil is recovered.

⑪ When the suction pressure reaches to
-26cmHg/-10inHg, the Recovery complete
lamp is on and the recovery machine stops
automatically.
⑫ Close both the low side and the high side
ports of the system.
⑬ Set the Power switch to the “OFF” position.
⑭ Set the valve of the recovery machine to the
“⓪ START” position.
