2.2 Intended use
Coordinate the use of the model for areas of use and media
other than those described with the Viega Service Center.
A ball valve is a fitting that is able to shut-off and open individual pipe‐
line sections through a 90° movement. The ball valve is not a control fit‐
ting and cannot be used for regulating volume flows. The ball must not
be in an intermediate position.
NOTICE!
Opening and closing the ball valve quickly can cause pres‐
sure shocks in the system.
– Always open and close the ball valve slowly.

SC-Contur
Product information
Easytop ball valve with SC-Contur 10 from 21

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 connection is guaranteed to leak 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 8.
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 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 spare part
designed for the intended application Ä Chapter 2.3.3
„Sealing elements“ on page 11. The use of other sealing ele‐
ments is not permitted.
3.1.2 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.
nInstallation is not dependent on the direction of flow.
Choose the place of installation so that the fitting is easily
accessible, simple to operate and the insulating shell can be
mounted without any problems.

Laying and fixing pipes
Length expansion
Removing the sealing element
Handling
Easytop ball valve with SC-Contur 16 from 21

Do not use pointed or sharp-edged objects to remove the
sealing element. They may damage the sealing element or
the bead.
Remove the sealing element from the bead.
Insert a new, undamaged sealing element into the bead.
Ensure that the sealing element is completely 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 16.
Inserting the sealing element
Handling
Easytop ball valve with SC-Contur 17 from 21

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.
In the case of pipes with a diameter of d 15–28 mm, the
pipe must be at least as long as the total insertion depth of
both press connectors.
Handling
Easytop ball valve with SC-Contur 18 from 21

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 sealing element is completely in the bead.
Push the press connector onto the pipe as far as it will go.
Mark the insertion depth.
Place the press jaw on 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 on the press connector at right
angles.
Check the insertion depth using the marking.
Ensure that the press jaw is placed centrally on the bead of the
press connector.
Handling
Easytop ball valve with SC-Contur 19 from 21

Carry out the pressing process.
Open and remove the press jaw.
ðConnection is pressed.
3.2.4 Leakage test
The installer must perform a leakage test before commissioning.
Carry out this test on a system that is finished but not covered yet.
Comply with the general rules of engineering and the applicable direc‐
tives, see Ä „Regulations from section: Leakage test“ on page 8.
Perform leakage test should in acc. with the general rules of engineering
for non-potable water installations.
Document the result.
3.3 Maintenance
NOTICE!
Inform your customer or the operator of the potable water
installation that the system has to be maintained on a reg‐
ular basis.
Observe the applicable regulations for the operation and maintenance
of potable water installations, see Ä „Regulations from section: Mainte‐
nance“ on page 8.
Viega recommends actuating the fitting regularly and
checking its function.
