using long piping)
Connect the piping
• Align the center of piping and sufficiently tighten the flare nut with fingers.
• Further tighten the flare nut with torque wrench in specified torque as stated in the table.
Piping size Torque
1/4" (6.35 mm) 18 Nym (1.8 kgf.m)
3/8” (9.52 mm) 42 Nym (4.3 kgf.m)
