Excess Materials/Recycling - LK Systems PE-X Assembly Instructions Manual

Assembly instructions | LK PE-X, PAL and PE-RT pipes
LK Universal system, with type-approved prod-
ucts, is ideal for this procedure. LK's Type ap-
provals can be used as certificates showing that
they have been tested in respect of strength.
LK Underfloor heating pipes (6 or 10 bar) can be
used for this method together with LK Under-
floor heating manifolds as they are manufactured
for a pressure of 6 bar. Manufacturer certificates
can be obtained from LK Systems AB.
Carefully follow the document "Förenklad täthet-
skontroll med luft för vissa rörsystem" (Simpli-
fied tightness testing with air for certain piping
systems). Use testing protocols, that are available
to download from www.sakervatten.se.
NOTE! The system must be depressurized imme-
diately when tightness testing is complete.
Overmolding of underfloor heating pipe
The pipe system must be pressurised when em-
bedding the pipes in screed and concrete. This is
to ensure that no damage occurs during the work.
Pay attention to the danger of freezing when em-
bedding PE-X pipes in concrete.
NOTE!
While the concrete cures, high temperature
are present in the concrete. In order to avoid
damage to the pipe caused by excessive
high pressure in connection with the curing of
the concrete, a 10 bar safety valve must be
mounted on the manifold/distributor. It is sug-
gested that a LK 514 Multisafe G15, 10 bar is
used, which is a mounted where a manual air
vent is located/fitted. Prior to commissioning,
remove the safety valve from the manifold/
distributor.

Existing tapwater and heating system
Guidance
Existing tapwater systems should undergo pres-
sure and tightness testing with the existing water
pressure of the tapwater system. Existing heating
systems should undergo pressure and tightness
testing with the existing operating pressure of the
heating system.
• Appoint a qualified person to lead
the work and set up testing protocol.
• Ensure that the installation and all fasteners,
fixings, supports, etc. are capable of with-
standing the loads during the test.
• Freezing risks must be eliminated.
• All joints must be visible and dry.
• Make sure that the measuring equipment is
working correctly.
Leftover excess materials/recycling
LK does not accept the return of packaging mate-
rials or surplus materials, except for materials in
unbroken and undamaged packaging.
Within the framework and scope of the produc-
er's responsibility, we are affiliated with to Pack-
aging and Newspaper Collection (FTI), which is
the industry's collection system for recycling of
packaging.
No pipes in the LK Universal System and the LK
Floor Heating Systems are classified as hazard-
ous waste, but rather these are handled as com-
bustible waste.
