2.3.2 Press connection with SC-Contur
Fig. 1: 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.
Product information
Easytop circulation regulation valve, static regulation valve with SC-Contur 9 from 25

Fig. 2: SC-Contur
Viega press connections are equipped with the SC-Contur. The SC-
Contur 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.
Viega guarantees that unpressed connections are visible during a
leakage test:
nwith wet leakage test in the pressure range from 0.1 hPa–0.65 MPa
(1.0 mbar–6.5 bar)
nwith dry leakage test in the pressure range from 22 hPa–0.3 MPa
(22 mbar–3.0 bar)
2.3.3 Sealing elements
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.

2.4 Information for use
2.4.1 Corrosion
Overground pipelines and fittings in rooms do not normally require
external corrosion protection.
There are exceptions in the following cases:
nContact with aggressive building materials such as nitrite or mate‐
rials containing ammonium
nin 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).
Product information

3 Handling
3.1 Assembly information
3.1.1 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 10. The use of other sealing ele‐
ments is not permitted.
3.1.2 Mounting instructions
Do not remove the model from the packaging until immedi‐
ately before use.
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.
Observe the following when mounting:
nuse suitable tools
nflow direction indicator
nWhen tightening the connection screw fitting, counter by holding the
key surface of the valve.
nA piece of straight pipe of at least 3xd should be installed upstream
from the fitting.
Choose the place of installation so that the fitting is easily
accessible, simple to operate and the insulating shell can be
well mounted.

3.2 Assembly
3.2.1 Replacing the sealing element
Do not use pointed or sharp-edged objects to remove the
sealing element. These could damage the sealing element or
bead.
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
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 3.1.3 „Required
tools“ on page 17.

Handling
Easytop circulation regulation valve, static regulation valve with SC-Contur 18 from 25

Cut the pipe properly using a pipe cutter or fine-toothed hacksaw.
Avoid grooves on the pipe surface.
3.2.3 Pressing the connection
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.
Handling
Easytop circulation regulation valve, static regulation valve with SC-Contur 19 from 25

Requirements:
nThe pipe end is not bent or damaged.
nThe pipe is deburred.
nThe correct sealing element is in the press connector.
EPDM = polished black
nThe sealing element is undamaged.
nThe complete sealing element is in the bead.
Push the press connector onto the pipe as far as it will go.
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.
