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 first 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-off/Manual Mode Switch to [Auto Shut-off] 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.
