FRIATEC FRIALEN, Fitting Instructions Manual

4.6

Inserting push fit ends or pipe ends into the fitting.

When the 

FRIALEN

®

 Safety Fittings

 and pipes are being assembled care

should be taken to ensure that the contact sockets are accessible to allow
connection of the fusion plug. Assembly  can be assisted by tapping around the
face with a plastic hammer at the same time. 

When assembling do not tilt.

The worked insertion end must be pushed into the fitting up to the mark. If
necessary hydraulic rounding clamps should be used (see Figure 6).

Repeated scraping of the outer diameter might be necessary if the tolerance
is big. Repeated scraping may not be performed to remedy installation
problems due to out-of-roundness!

If the fitting cannot be slipped on without using force despite the above
described procedure, a repeated scraping is permitted. (see item 4.4).

A simple control of the high points is possible by installing the coupler and
evaluating the annular gap.

4.7

Ensuring a tension-free assembly of the components

All joints prepared for fusion must be tension-free. Pipes may not be positioned
in the 

FRIALEN

®

 Safety Fitting 

under bending stress or self-load. After the

installation on the pipe ends, it must still be possible to move the couplers by
hand.

If required, the piping or the fitting is to be supported or suitable fixing
facilities are to be used. The tension-free fixing of the joint is to be maintained
until the cooling time stated on the barcode and in the table is reached. (see
item 4.9).

Before starting the fusion process, check again based on the markings
whether the position of the pipe insertion end in the FRIALEN

®

 Safety Fitting

has shifted (correct, if required).

WARNING!
A non-tension-free or shifted joint
may result in an impermissible melt
flow and a defective joint during
fusion (see Figure 8).
