2. Guideline for each installation process
2.4 Insulation work
2.4.1 Insulation

1) Operational steps

1 EPDM length should be more
longer than pipe length.
Do not extend EPDM by force.
2) Bending vertical side of insulation
1 Use the original uncut insulation
material.
3) 'L' Fitting connection part insulation
1 All of the fitting connecting parts
should be insulated.
Bring face to face the each end of
EPDM on fitting connection part.
2 Put the pipe in EPDM insulation
carefully so that the pipe will not
get damaged with EPDM.
2 Only in specialcase is the vertical
cutting of the insulation allowed.
2 Make fitting cover to fit the EPDM
insulation fitting cover should be
overlapped with insulation min 1
inch (2.5cm).
3 Bond on both side of cut surfaces
of move sure to use the correct type
of bond for EPDM cut surface
attaching.
3 Bond both sides of the surface of
EPDM and press them together for
long lasting bonding.
3 Bond the both cutting sides of
fitting cover.

and does not get detached.
4 Dry it until it becomes thick and
