ASSEMBLY AND INSTALLATION INSTRUCTIONS
Hole Repair
In the case you make a hole in a PP-R pipe, it is possible
to repair it by using the special tool to be mounted
on the multi caster and the special hole repair patch
(Fig. 1).
Fig. 1
Changing the insert
Should the female Ø 1/2” insert accidentally break, it
is not necessary to remove the fitting – breaking tiles
and masonry – but it is possible to avoid all of this by
using the special repair KIT and replacing only the
threaded ring nut (Fig. 2). Fig. 2
Using the bracket
In order to make execution of PP-R systems simpler and more effective, Coes has designed
and patented the bracket for fixed point for securing threaded terminals.
1 Screw on the bored 1/2” pawl (1) on the insert to be replaced.
2 Mark the depth of the insert, 18 mm, with chalk on the hole saw (2) and cut, pivoting in the
hole.
3 Set the extended matrix (3) on the insert for heating.
4 To make extraction of the pawl to be replaced easier, use a 1/2” bar of pipe threaded on
one side (4).
5 Plane the bottom of the fitting with the mill (5), holding the drill forcefully until the four
protuberances on the bottom have reached a thickness of about 0.5-1 mm
6 Thoroughly clean the surfaces to be welded with alcohol.
7 Heat the fitting with the extended male matrix.
8 Screw the new insert (8) on a 1/2” bar of pipe and heat it with the female matrix D 32 for
about 7/8 seconds.
9 Weld while pushing the insert down to the bottom of the fitting.
10 Before connecting to the thread, the welding must be completely cold.
