Pipelaying - LK Systems PE-X Assembly Instructions Manual

Vertical laying
With vertical installation, fixing must be locat-
ed at T-junctions unless the shank length of the
branch pipe is sufficient according to the section
entitled Expansion-absorbing devices in the proj-
ect planning and design guidance.
Example of clamping, vertical installation.
Suspension between fixed points must take place
as follows.
Visible installation:
LK Universal Maximum distance between suspen-
Pipe sion points
X16 - X25 0.5 m
A16 - A25 1.5 m
A32 - A75 2.0 m
Concealed installation:
LK Universal Maximum distance between suspen-
Pipe sion points
X16 - X25 2.5 m
A16 - A75 2.5 m

Pipelaying

• Always use the system products in the
LK range and never mix different product
makes.
• There must be no unused outlets for cold
water, hot water or hot water circulation
pipes
• Cold and hot water pipes must be installed
such that they do not come into contact with
one another.
• Hot water circulation pipes must not be adja-
cent to cold tapwater without the requisite
insulation.
• Pipes for heating systems must not be adja-
cent to cold tapwater without the requisite
insulation.
• No water pipes may be placed in uninsu-
lated areas such as crawl space foundations
or attics. Pipes may be laid in special installa-
tion areas in floors, exterior walls or loft floor
structures on the warm side of the structure,
inside the airtight foil, or in a frost-free space
below ground level.
• See the relevant section in the project plan-
ning and design guidance with regard to
heat emission from pipelines.
Pipe lead-throughs in floors
There must be no pipe lead-throughs in floors
with sealing layers in bathrooms or shower
rooms.
Pipe lead-throughs in the floors of laundry rooms,
equipment rooms or other areas for water heat-
ers, heat pumps or similar may be installed using
grommets. In smaller houses, without a laundry
room or other utility rooms, the pipe inlets to the
water heater, heat pump, etc. can be fitted with
a pipe sleeve in the bath or shower room floor,
though not at the location of the bath or shower.
Use grommets with OD 40 and 50 mm (e.g.
drainage pipes). Install a LK Sealing sleeve on the
outside of the grommet and the inner pipe. Suit-
able for both corrugated and smooth inner tubes
with OD 20, 25, 32 and 34 mm.
