Assembly instructions for LK PE-X, PAL and PE-RT pipes
General
These assembly instructions relate to installations
implemented using LK PE-X, LK PAL and LK Heat
pipes in the PE-X and PE-RT execution.
• The designation "LK Universal PE-X pipe"
refers to pipes of homogeneous PE-Xa.
• The designation "LK Heat pipe" is avail-
able in two variants, homogeneous PE-Xa or
homogeneous PE-RT.
• The designation "LK Universal PAL pipe"
refers to composite pipes of PE-RT/Alumini-
um/PE-RT.
All types of pipes are diffusion-tight for use in
heating and cooling systems. Refer to the table
on page 2 for designation, pipe dimension, pipe
material, design, pressure class, temperature range
as well as manufacturing standard.
Storage and handling
LK pipes may not be stored or installed in a way
that they are exposed to direct sunlight (max. 3
months). This is also applicable to LK Pipe-in-
pipe. Packaging provides sufficient protection
against UV radiation. Once installation is com-
plete the pipes should not be exposed to direct
sunlight other than occasionally. Window panes
provide sufficient protection against UV ra-
diation and so do not affect the good long-term
properties of the pipe.
