Cleaning
The surfaces of the pipes to be fused
and the interior surfaces of the
FRIALEN
®
Safety Fittings must be
absolutely clean, dry and free from
any grease. These areas are to be
cleaned with a suitable cleaning
agent and
exclusively with ab-
sorbent, lint-free and non-dyed
paper
directly before the assembly
and after scraping (see Figure 7).
We recommend PE cleaning agents which meet the requirements of the test
basis DVGW-VP 603, e.g. AHK cleaning agents.
When cleaning, ensure that no contaminations from the unscraped pipe
surface are introduced into the fusion zone.
WARNING!
When using alcoholic cleaning agents, the alcohol percentage must be
at least 99.8% according to DVGW-VP 603.
The cleaning agent
must be completely evaporated
before starting the
fusion process.
Now, using the
FRIALEN
®
marker,
re-mark the line (approx. 120
°
distri-
buted around the circumference) to show the width of the fusion zone on the
pipe since this will have been removed by scraping and cleaning.
The joint surfaces must be clean and dry before installing the fitting. The
cleaned fusion zone should not be touched with bare hands. Moisture in the
area of the joint area, e.g. because of dew or frost, is to be removed using
suitable aids.
The fusion fitting is to be removed from the packaging only directly before
the planned processing. The packaging protects the fittings against external
influences during transport and storage.
