NOTE
∙ Be sure to insulate the pipes without gaps or cracks,
and use adhesive between the connecting parts of the
insulation to prevent moisture from entering.
∙ When bending the pipe, try to secure a large bending
radius (over 100 mm) to prevent the copper pipe
from distorting.
∙ Use the polyethylene or EPDM foam insulation with a
thickness over 7 mm.
∙ If pipes are installed in a place with humidity
over 80% (such as in a building site pit, basement,
seashore, near hot springs, or lakes), use an insulation
of a thickness over 10 mm.
∙ Make sure that the thickness of the insulation does
not get thinner on the pipe's bending area.
∙ When the insulation thickness becomes thinner, use
extra insulation to maintain thickness.
∙ When installing the pipe hanger, use extra PE- foam
insulation (over 5 mm) to make the width of the
insulation 3 times wider than the hanger. Do not use
cable ties as a pipe hanger.
