(2)B oth of the LOK R ING is pushed up to the stop
(3)The bending point is not too close to the joint
ending.
(4)During the assembly it is important that both
ends remain completely within the joint.
• F or a hermetically sealed metal/metal
connection, the tube ends have to be
clean.

(1)When measuring with pirant Vacuum gauge
the charging M/C , vacuum degree is within 1
Torr.
(2)If the vacuum degree of the cycle inside is 10
Torr. below for low pressure and 20 Torr. for
high pressure, it says no vacuum leakage
state.
(3)Vacuum degree of vacuum pump must be,
0.05 Torr. below after 5 min.
(4)Vacuum degree must be same to the value
described item above for more than 20 min.
• Apply M/C Vacuum G auge without fail.
• P erform vacuum operation until a proper
vacuum degree is built up.
• If a proper vacuum degree isn't built up,
check the leakage from the C ycle P ipe line
part and Quick C oupler C onnecting part.
