• After leak test, insulate both the gas and liquid piping connection with the attached joint insulating mate-
rial (6) and (7) to prevent the piping from getting exposed. (Refer to Fig. 22)
Then, tighten the both ends of insulating material with the clamp (4).
• Wrap the sealing material (Small) (9) around the joint insulating material (6) (7).
• Make sure to bring the seam of joint insulating material (6) and (7) to the top.
• When carrying out upward and rightward piping, use the attached L-shaped piping, and insulate the 2
places of connection. (Refer to Fig. 23)
In addition, bend the liquid side field piping using a bender with radius is 40mm or less.
If the attached L-shaped piping is not used or the piping is bent with a bender with radius more than
40mm, it may interfere with other piping or drain hose.
