1. It is recommended that a
support bracket is tted for
every 1 metre of extension
pipe used and a bracket
should be used at every joint,
to ensure pipes are held at
the correct angle.
If a slip joint coupling is to be
used then a bracket should
be used to secure the collar.
2. Only use water as lubricant
during assembly.
