1) Operational steps
2) Bending vertical side of insulation
3) 'L' Fitting connection part insulation
EPDM length should be more
longer than pipe length.
Do not extend EPDM by force.

Use the original uncut insulation
material.
1
All of the fitting connecting parts
should be insulated.
Bring face to face the each end of
