Joining Instructions
: |
|
| |
 |
Make sure that spigot end and
inside of socket is clean and the sealing ring
is placed evenly in the socket.
|
|
When cutting pipes make sure
they are cut square. Chamfer the end cut to an
angle of 15° with a medium file.
|
|
A correct depth of entry of the
spigot into the socket is required to allow thermal
movement. To achieve this, push spigot fully into
the socket (remove sealing ring at this time)
and make a mark on the spigot. Withdraw the spigot
by 10mm & mark the spigot with a bold line.
This bold mark indicates the correct depth of
entry to allow the necessary expansion gap.
|
|
Smear PARAS rubber lubricant
evenly on the chamfered spigot and the sealing
ring. Then insert the spigot into socket with
light twisting motion. Pull out the pipe to allow
10mm expansion gap.
|
|
The joint is now complete and
requires no additional mastics, tape or cement
or any other joining sealants.

PRECAUTIONS |
|
| |
|
Only UV stabilized uPVC
SWR pipes with rubber ring should be used.
The regular uPVC Pipes with solvent cement
joining when exposed to sun-rays/weather
get brittle and brownish.
|
|
Use only rubber lubricant
for joining SWR Pipes & Fittings, where
rubber ring is used.
|
|
Avoid over tightening of
door caps. Proper placement of rubber ring
should be confirmed before tightening.
|
|
Avoid misalignment of vertical
SWR Pipe stacks and incorrect spacing of
Pipe clips.
|
|
Cutting of UV stabilized
SWR Pipe should be straight as diagonal
cutting may leads to leakage.
|
|
|
|
|
|
| |
|
All entry to main stacks should
be protected with water seal trap, wherever there
is mixing of Soil & Waste lines.
|
|
Keep a gap of 10mm between all
UV stabilized SWR Pipes and Fittings to accommodate
thermal expansion and contraction of pipes for
longer life of the system.
|
|
Smoke Test should be avoided
and test plug / socket plug should be used for
testing the lines.
|
|
Horizontal lines within bathrooms
should be cement encased and tested before compacting
of sunken floor to avoid any accidental damages.
|
|
For further technical information
/ assistance, the manufacturer to be contacted
for required clarification.
