Straight pipe length
z
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
5-7/8 in. (150 mm) 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.

CAUTION
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.
