6-6 PIPING INSULATION
•
After the gas leak inspection is completed, refer to the following figures and use the included insulation tube
3) and clamps 2) to apply the insulation.
NOTES
•
Insulate all of the piping including the liquid pipes, HP/LP gas pipes, suction gas pipes, gas pipes, and the
pipe connections for these. Not insulting these pipes could result in water leaks or burns. In particular, suc-
tion gas flows in the HP/LP gas pipes during full cooling operation, so the same amount of insulation as
used for the suction gas pipes is required. In addition, high-pressure gas flows in the HP/LP gas pipes and
gas pipes, so use insulation that can withstand more than 120°C.
•
When reinforcing the insulation material for the installation environment, also reinforce the insulation on the
piping protruding from the unit and on the pipe connections. Locally purchase the insulation required for the
reinforcement work.
