Insulation of field piping must be carried out up to the con-
nection inside the casing. If the piping is exposed to the
atmosphere, it may cause sweating or burn due to touching
the piping, electric shocks or a fire due to the wiring touch-
ing the piping.
• After leak test, referring to Fig. 15, insulate both the gas and
liquid piping connection with the attached joint insulating
material (6) and (7) to prevent the piping from getting
exposed. Then, tighten the both ends of insulating material
with the clamp (4).
• Wrap the sealing material (Small) (9) around the joint insulat-
ing material (6) (flare nut section), only the gas piping side.
• Make sure to bring the seam of joint insulating material (6)
and (7) to the top.
