Manual

● In case of recycling R134a, the efficiency of the heat exchanger in Oil Separator is not adequate

even if the ambient temperature is 10℃ or higher.

Liquid R134a accumulates in Oil Separator and the full tank sensor unit.

● Connect Liquid Charge Adapter 1/4" (A) and Filter (B) between the suction hose and the manifold

center port.

● Warm up the unit every time regardless of temperature. (Refer to page 16 "Warm Up Operation".)

● If the pressure of the recycled R134a is low (if the temperature is low), warm the R134a in the

cylinder with a heater to increase the pressure.

(A) Code No. Y41123

Liquid Charge Adapter 1/4 "

■ Operation method

① Connect hoses as above after carrying out procedure on Page 9 " 2) Evacuation of the recycle

unit and the hoses".

② Set Auto Shut-off/Manual Mode Setting to [Auto Shut -off] position.

③ Set Power Switch to [ON] and press Start Switch once.

④ Adjust Suction Pressure between 0.1MPa (14.5psi) ～ 0.2MPa (29psi) by opening the suction hose

ball valve from the manifold and keep operating until discharge pressure becomes 1.0MPa (145psi).
