● In case of recycling R134a, the e󱐰ciency 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 " 1 piece
(B) Code No. TF011 Filter 1 piece
■ 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-o󱐯/Manual Mode Setting to [Auto Shut -o󱐯] 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).
HOW TO USE

⑤ After ④ , turn Suction Valve (V1) to [OPEN] position.
⑥ Open the suction hose ball valve from the manifold slowly for approximately 20 seconds.
⑦ Follow usual recycle procedure.
■ Note ( CAUTION )
(1) R134a has a high boiling point and is harder to gasify than R410A.
Avoid working in a low temperature environment as much as possible.
(2) Even if the normal recycling procedure is performed after a warm-up operation, if the oil tank
full sensor stops the procedure, reduce Suction Pressure to less than 0.2MPa (29psi) to prevent
R134a from accumulating.
(3) The recycle speed of R134a is slower than R410A.
Adjust the timing to replace Molecular Sieve Replacement Kit considering the condition of
recycled R134a.
Press Reset Key of Auto Stop Timer at rst automatic stop to initialize the timer to replace
Molecular Sieve Replacement Kit, and Filter at the second automatic stop (40 hours).
(4) If the surface of Filter connected to the manifold becomes frozen during recycling and it
stops recycling, replace or clean Filter according to the following procedure and then restart
recycling:
1 - Set Auto Shut-o󱐯/Manual Mode Switch to [Auto Shut-o󱐯] and close the high pressure side
valve of the manifold.
2 - Close the suction hose ball valve from the manifold.
3 - Wait until the unit stops automatically.
4 - When the unit stops, carefully remove Filter. (Be careful of squirting liquid R134a.)
5 - Clean or replace Filter and Liquid Charge Adapter 1/4".
6 - Connect Filter and Liquid Charge Adapter 1/4" to the center port of the manifold.
7 - Connect the suction hose to Liquid Charge Adapter 1/4" and open the high pressure side valve
of the manifold and the suction hose ball valve from the manifold.
8 - Press Start Switch once to resume recycling.
HOW TO USE

Refrigerant Recycle Equipment
● Use the following procedure when refrigerant which becomes high pressure due to temperature
rise. Refer to page 10 "Recycle Procedure".
● Even if the cylinder is not full, if the inside pressure of the cylinder is high, replace it with an

① Setting up as the above drawing.
② Turn Switching Valve (V2) to [PURGE] position.
＊ Do not turn the valve during operation or Discharge Pressure Gauge may be damaged.
③ Set Auto Shut-o󱐯/Manual Mode Setting to [Auto Shut-o󱐯] position.
＊ When using the Auto Shut-o󱐯 mode, the unit does not starts when Suction Pressure is lower than
atmospheric pressure.
④ Set Power Switch to [ON] position.
Push Start Switch once.
⑤ Turn Suction Valve (V1) slowly to [PURGE] position adjusting Suction Pressure to less than
0.2MPa.
⑥ Close the liquid port of the cylinder when the unit stops automatically.
⑦ Turn Discharge Valve (V3) to [CLOSE] position and close the discharge hose ball valve.
⑧ Set Power Switch to [OFF] position.
⑨ Disconnect the hoses.
＊ Vapor refrigerant remains in the recycle unit and the hose of the discharge side.
Connect the hose of the discharge side to an evacuated cylinder to recover all refrigerant in the
recycle unit and the hose.

.
④ Set Power Switch to [OFF] position.
⑤
Adjust Suction Pressure between 0.1MPa
（14.5psi） ～ 0.2 MPa（29psi） by opening the
suction hose ball valve from the manifold.
⑥ Remove the cap of Oil Discharge Port on the
back of the unit.
⑦ Open the valve slowly and discharge the oil
into another container.
＊ The oil tank capacity is 2L.
⑧ Close the valve and cap of Oil Discharge Port
after discharging the oil.
Check every 100 hours of operation for any oil or contamination in the Electrostatic Filter System.

MAINTENANCE&INSPECTION
Maintenance
● Inspect and clean regularly as instructed below and perform correction or replacement timely.
① Remove all refrigerant from the unit until
0MPa（psi）.
② Open the lid of Dry Filter and remove Dry
Filter Cartridge and two O-rings in Dry
Filter Housing(G-85,P-24) and one O-ring in
Lid(P-80).
③ Open the lid of Dry Filter Cartridge and
remove Spring, Mesh Plate, and Filter.
④ Take out Molecular Sieve and two Filters in
the bottom.
Dry Filter Cartridge is installed at the back side of the unit.
● Replacement period
・ ・・R410A : Every 20 hours (every automatic stop by Auto Stop Timer)
・ ・ ・ R32･R134a : Every 40 hours (every other automatic stop by Auto Stop Timer)
● Replace Filter TF011 together with Molecular Sieve at the same time.
⑤ Prepare Molecular Sieve Replacement Kit
(AR338) and replace three Filters and
Molecular Sieve. Two O-rings will be replaced
later on.
⑥ Set Mesh Plate and Spring in Dry Filter
Cartridge and close the lid.
⑦ Properly set two new O-rings from AR338 on
Dry Filter Housing and put the refilled Dry
Filter Cartridge into the unit and close the lid
securely with the holding spring.
