2.3.2 Press connection with SC-Contur
Product information
SC-Contur
Fig. 2: Press connection using a press connector as an example
The press connection has a circumferential bead in which the sealing
element lies. The connector is deformed upstream and downstream of
the bead and permanently connected to the pipe during pressing. The
sealing element is not deformed during pressing.
Fig. 3: SC-Contur
Viega press connections are equipped with the SC-Contur. The SCContur is a safety technology that is certified by the DVGW and ensures
that the connection is guaranteed to be leaky in an unpressed state. In
this way, unpressed connections are noticed immediately during a
leakage test.
Easytop concealed straight seat valve with SC-Contur 10 from 23
Page 11
Viega guarantees that unpressed connections are visible during a
leakage test:
n with wet leakage test in the pressure range from 0.1 hPa–0.65 MPa
(1.0 mbar–6.5 bar)
n with dry leakage test in the pressure range from 22 hPa–0.3 MPa
(22 mbar–3.0 bar)
2.3.3 Sealing elements
Area of use of the EPDM sealing element
Product information
NOTICE!
Only EPDM sealing elements are approved in potable water
installations. The use of other sealing elements is not per‐
mitted.
The model is factory-fitted with EPDM sealing elements.
2.3.4 Markings on components
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 model is marked as follows:
n flow direction indicator
n noise class I pursuant to applicable regulations, see Ä „Regulations

Overground pipelines and fittings in rooms do not normally require
external corrosion protection.
There are exceptions in the following cases:
n Contact with aggressive building materials such as nitrite or mate‐
rials containing ammonium
n in aggressive surroundings
If external corrosion protection is required, observe the pertinent guide‐
lines, see Ä „Regulations from section: Corrosion“ on page 7.
Easytop fittings made of gunmetal/silicon bronze are suit‐
able for all types of potable water.
The chloride concentration in the medium must not exceed
a maximum value of 250 mg/l.
This chloride is not a disinfectant, but in fact pertains to the
content in sea and table salt (sodium chloride).

3.1.2 Permitted exchange of sealing elements
Important instruction
With their material-specific qualities, sealing elements in
press connectors are adapted for use with the corre‐
sponding media and/or the areas of use of the piping sys‐
tems and are generally only certified for them.
The exchange of a sealing element is generally permitted.
The sealing element must be exchanged for a designated
spare part for the intended application Ä Chapter 2.3.3
„Sealing elements“ on page 11. The use of other sealing ele‐
ments is not permitted.

3.2 Assembly
3.2.1 Replacing the sealing element
Removing the sealing element
Handling
Do not use pointed or sharp-edged objects to remove the
sealing element. These could damage the sealing element or
bead.
Inserting the sealing element
Remove the sealing element from the bead.
Insert a new, undamaged sealing element into the bead.
Ensure that the complete sealing element is in the bead.

3.2.2 Shortening the pipes
Handling
NOTICE!
Leaky press connections due to damaged material!
Press connections can become leaky due to damaged
pipes or sealing elements.
Observe the following instructions to avoid damage to pipes
and sealing elements:
– Do not use cutting discs (angle grinders) or flame cutters
when cutting to length.
– Do not use grease or oils (e. g. cutting oil).
For information about tools, also see Ä Chapter 3.1.4 „Required
tools“ on page 17.
3.2.3 Pressing the connection
Cut the pipe properly using a pipe cutter or fine-toothed hacksaw.
Avoid grooves on the pipe surface.
NOTICE!
Leaky press connections due to pipes being too short
If two press connectors are to be mounted onto a pipe
without an interval, the pipe must not be too short. If the
pipe is not inserted up to the prescribed insertion depth in
the press connector during pressing, the connection may
become leaky.
With pipes with a diameter of d 15–28 mm, the length of the
pipe must be at least as long as the total insertion depth of
both press connectors.
Easytop concealed straight seat valve with SC-Contur 19 from 23
Page 20
Requirements:
n The pipe end is not bent or damaged.
n The pipe is deburred.
n The correct sealing element is in the press connector.
EPDM = polished black
n The sealing element is undamaged.
n The complete sealing element is in the bead.
Push the press connector onto the pipe as far as it will go.
Handling
Mark the insertion depth.
Place the press jaw onto the press machine and push the retaining
bolt in until it clicks into place.
INFO! Observe the press tool instruction manual.
Open the press jaw and place at a right-angle onto the connector.
Check the insertion depth using the marking.
Ensure that the press jaw is placed centrally on the bead of the
press connector.
