8.2 Laying the pipe
1.
Use a de-coiler to unwind the pipe off the coil without kinking
the pipe.
2.
Use conduit type cutter to produce a clean burr free cut
3.
Lay pipes in either spiral or serpentine laying pattern as
selected Refer section 4.1
4.
Securely fix the pipe to the mesh at a maximum of 600 spacing using plastic cable ties or
plastic coated copper wire –
DO NOT USE BARE COPPERWIRE AS
THIS WILL VOID THE WARRANTY.
5.
Fit corrugated sleeves around the pipes for one (1) metre from the
manifold into the slab. This gives added protection at the point of entry
and exit from the slab.
6.
Start the circuit installation from the header out to the room entering and
exiting the selected room through the doorways only.
7.
The length of all circuits should be approximately the same; ideally each circuit should be
the full length of the pipe coil (100 metre).
8.3 Construction – expansion joints
Where expansion joints in the concrete are required as
part of the building structure the following precautions
should be noted:
•
Avoid crossing expansion joints wherever possible
•
Where a crossing is unavoidable, ensure that the
pipe is at 90deg to the construction joint and that a
sleeved conduit is fitted over the pipe for a distance
of 200mm (minimum) either side of the expansion
joint.
