Straight pipe length
When connecting the main piping, do not bend
it near the connection section.
If the main pipe must be bent due to unavoidable
circumstances, ensure that the linear section is
150mm or more.
HEAT INSULATION INSTALLATION
After connection the pipes, use the supplied heat insulation to insulate them.
Remove the protective sheet from the double-stick tape that is affi xed to the heat insulation.
Use tape (field supply) to seal the seam so that there will be no gap at the junction between the
aforementioned heat insulation and coupler insulation, and between coupler insulation and the
heat insulation on the local piping.

(Gas pipe ... Large)
(Liquid pipe ... Small)
Be sure to install the heat insulation on liquid pipes and gas pipes. Unless they are thermally
insulated, water condensation can cause accidents or reduction in performance.
After installing the heat insulation, if you worry about possible condensation due to the high
humidity of installation position, please use locally procured heat insulation to reinforce insulation.
