Installation
One secure fixed anchor bracket must be installed per
floor when branch connections exist and at a maximum of
6 metre centres on plain straight runs of pipe.
The special shape of the seal allows the pipe to slide
within the socket during expansion and contraction,
ensuring that the connection remains perfectly watertight
even under heavy hydraulic load.
The following conditions are important to ensure perfect
and easy assembly of the sleeve:
1
Chamfering the inserted pipe end to
approximately <) 15°.
2
Check the scale on the outer surface of the
expansion socket for insertion depth.
3
Mark the correct insertion depth on the pipe.
4
Lubricate the pipe end well with soluble lubricant,
silicone or Vaseline. Do not use oil or grease which
can damage the rubber seal.
When using expansion fittings, all other joints must
be tension resistant (see page 18).
Horizontal assembly (e.g. at 20°C)
Example: insertion
depth in an ambient
temperature of 20°C
(vertical assembly).
