Only pipe clamps with chloride-free sound insulating inlays should be
used to secure the pipes.
Observe the general rules of fixing technology:
nDo not use fixed pipelines as a support for other pipelines and com‐
ponents.
nDo not use pipe hooks.
nObserve distance to connectors.
nObserve the expansion direction: Plan fixed and gliding points.
Make sure to affix the pipelines in such a way as to de-couple them
from the installation body, so that they cannot transfer any structure-
borne sound, resulting from thermal expansion or possible pressure
surges, onto the installation body or other components.
Observe the following fixing intervals:

Pipelines expand with heat. Heat expansion is dependent on the mate‐
rial. Changes in length lead to tension within the installation. These ten‐
sions must be equalised with suitable measures.
The following are effective:
nFixed and gliding points
nExpansion equalisation joints (expansion bends)
Heat expansion co-efficients of various pipe materials

cient ⍺

Calculation example multilayer pipe:
nGiven: Temperature difference Δϑ = 50 K; Pipe length L = 8 m; Pipe
⌀ = 20 mm
nRequired: Expansion bend length LBS
nCalculation:
– Beginning in the left-hand diagram: From 50 K temperature dif‐
ference on the x-axis up to the characteristic line for the 8 m
pipe length.
– Connect the intersection horizontally with the right-hand dia‐
gram up to the intersection of the characteristic line for pipe
diameter 20 mm.
nResult: Read the value from the x-axis: LBS = 480 mm.

2.3.3 Press connectors
Press connectors are available in a number of shapes. An overview of
the press connectors suitable for the system can be found in the cata‐
logue.
The press connectors of the Viega Smartpress system consist of the fol‐
lowing materials:
nGunmetal/silicon bronze
nStainless steel
nPPSU
Fig. 3: Viega Smartpress connectors
Product information
Viega Smartpress 12 from 23

Fig. 4: SC-Contur
Viega press connectors are equipped with the SC-Contur. The SC-
Contur is a safety technology that is certified by the DVGW and ensures
that the connector is guaranteed to be leaky in an unpressed state. In
this way, inadvertently unpressed connections are noticed immediately
when filling the system.
Viega ensures that inadvertently unpressed connections during installa‐
tion become visible when the system is filled.
nwith wet leakage test in the pressure range from 0.1–0.65 MPa (1.0–
6.5 bar)
nwith dry leakage test in the pressure range from 22 hPa–0.3 MPa
(22 mbar–3.0 bar)
2.3.4 Markings on components
The pipe markings contain important information regarding the quality
and certification of the pipes. Their meaning is as follows:
nmanufacturer
nSystem name
npipe material
nsize / wall thickness
ncertification and operating temperatures
The press connections are marked with a coloured dot. This identifies
the SC-Contur, where the test medium would escape in the case of an
inadvertently unpressed connection.

The green dot shows that the press connector is equipped with the
SC-Contur and that the system is suitable for drinking water.
2.3.5 Mixed installations
To ensure proper function, the Viega Smartpress connectors may only
be used with the Viega pipes from the systems Viega Smartpress, Pexfit
Pro, and Pexfit Fosta. Since the use with pipes of other systems or by
other manufacturers has not been tested, proper function cannot be
ensured in this case.
Installation of Viega Smartpress pipes with old Pexfit Fosta connectors
is not permitted.
Please contact the Viega Service Center for questions on this subject.

2.4 Information for use
2.4.1 Chemical resistance
NOTICE!
Damage to material due to aggressive chemicals
Aggressive chemicals, especially those containing solvents,
may cause material damage and leaks. This may lead to
water damage.
– Prevent contact between the system components and
aggressive chemicals.
NOTICE!
Material damage due to impermissible leakage detection
agents
Impermissible leakage detection agents may cause material
damage and leaks. This may lead to water damage.
– Use only leakage detection agents approved by the
manufacturer for use on PPSU material.
– Observe the manufacturer's notes on processing.
Protect the system components against excessively high concentra‐
tions of chloride generated by both the medium or in the area around
the area of use. An excessive chloride concentration can lead to corro‐
sion in stainless steel systems.
The chloride concentration in the medium must not exceed a maximum
value of 250 mg/l.
The following rules apply for avoiding external contact with materials
containing chloride:
nInsulating materials must not have a water-soluble chloride ion con‐
tent by weight that exceeds 0.05 %.
nThe sound insulating inlays on the pipe clamps must not contain
leachable chloride.
nStainless steel components must not come into contact with building
materials or mortar containing chloride.
If external corrosion protection is required, observe the general rules of
engineering, see Ä „Regulations from section: Chemical resistance“
on page 6.

3.1 Storage
For storage, comply with the requirements specified in the applicable
regulations, see Ä „Regulations from section: Storage“ on page 6:
nStore rods on even, clean surfaces.
Storage outside in closed, original packaging is possible for a period of
up to three months. In this instance, protect the packaging from
damage due to rain or high levels of humidity.
3.2 Assembly information
3.2.1 Mounting instructions
NOTICE!
Material damage due to thread locker containing solvents!
Thread lockers containing solvents can lead to material
damage and leaks in plastic parts of pipe connections. This
may lead to water damage.
– As a sealant, only use commercially available hemp
together with thread sealing paste or certified sealing
tape for potable water.
– Please contact the Viega Service Center if you have any
questions.
System components may, in some cases, become damaged through
transportation and storage.
nCheck all parts.
nReplace damaged components.
nDo not repair damaged components.
nContaminated components may not be installed.
