PIPING INSULATION

(1) Install the coupler heat insulation (large and small) and insulation (long and short) on each pipe as
shown in the gures below.
(2) Attach the butting surface with no gap to eliminate any gap between the insulations.
(3) During the pipe insulation work, prevent air from getting inside the insulation with an adhesive tape
(eld supply).
