Press connection with SC-Contur
The press connection has a circumferential bead in which the sealing element lies. The press 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.
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 connection is guaranteed to be leaky in an unpressed state. In this way, inadvertently unpressed connections are noticed immediately during a leakage test.
Viega guarantees that unpressed connections become visible during a leakage test:
with the wet leakage test in the pressure range from 0.1–0.65 MPa (1.0–6.5 bar)
With dry leakage test in the pressure range from 22 hPa–0.3 MPa (22 mbar–3.0 bar)
Sealing elements
NOTICE!
Only EPDM sealing elements are approved in potable water installations. The use of other sealing elements is not permitted.
The model is factory-fitted with EPDM sealing elements.

Information for use
Corrosion
Overground pipelines and fittings in rooms do not normally require external corrosion protection.
There are exceptions in the following cases:
Contact with aggressive building materials such as nitrite or materials containing ammonium
in aggressive surroundings
If external corrosion protection is required, observe the pertinent guidelines, see Regulations from section: Corrosion .
INFO!
Easytop fittings made of gunmetal/silicon bronze are suitable 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).

INFO!
Important instruction
With their material-specific qualities, sealing elements in press connectors are adapted for use with the corresponding media and/or the areas of use of the piping systems 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 Sealing elements . The use of other sealing elements is not permitted.
Mounting instructions
Checking system components
INFO!
Do not remove the model from the packaging until immediately before use.
System components may, in some cases, become damaged through transportation and storage.
Check all parts.
Replace damaged components.
Do not repair damaged components.
Contaminated components may not be installed.
During assembly
A blind flange ensures unhindered operation until assembly is completed.
Observe the following when mounting:
Flow direction indicator
Minimum / maximum installation depth
Use suitable tools
INFO!
Choose the place of installation so that the fitting is easily accessible and simple to operate.
Laying and fixing pipes
For information, refer to the instructions for use of the Profipress, Sanpress and Sanpress Inox systems.
Length expansion
For information, refer to the instructions for use of the Profipress, Sanpress and Sanpress Inox systems.
Required tools
The following tools are required for production of a press connection:
Pipe cutter or a fine-toothed hacksaw
Deburrer and coloured pen for marking
Press machine with constant pressing force
Press jaw or press ring with corresponding hinged adapter jaw, suitable for the pipe diameter and with suitable profile
Assembly
Replacing the sealing element
Removing the sealing element
INFO!
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.
Inserting the sealing element
-
Insert a new, undamaged sealing element into the bead.
-
Ensure that the complete sealing element is in the bead.
Shortening the pipes
NOTICE!
Leaking 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 Required tools .
-
Cut the pipe at a right angle using a pipe cutter or fine-toothed hacksaw.
Avoid grooves on the pipe surface.
Pressing the connection
NOTICE!
Leaking 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.
Requirements:
The pipe end is not bent or damaged.
The pipe is deburred.
The correct sealing element is in the press connector.
EPDM = polished black
The sealing element is undamaged.
The 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 it at a right-angle onto the press connector.
-
Check the insertion depth using the marking.
-
Ensure that the press jaw is placed centrally on the bead of the press connector.
-
Carry out the pressing process.
-
Open and remove the press jaw.
-
Connection is pressed.
Mounting the valve
INFO!
Carry out a function test after mounting.
Installation is possible in masonry (wet construction) and in dry constructions (pre-wall / duct installations).
Attaching in dry constructions
-
Attach the protective sleeve of the valve in front of and behind the cladding (e.g. sheetrock or Fermacell panels) with lock nuts.
-
Seal the wall lead-in on the front side of the wall with the self-adhesive sealing flange.
Actuating the valve
-
Open or close the valve clockwise or anti-clockwise respectively.
-
During the preliminary building work phases:
Actuate the valve via the protective cap.
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 directives, see Regulations from section: Leakage test .
Document the result.
Maintenance
NOTICE!
Inform your customer or the operator of the potable water installation that the system has to be maintained on a regular basis.
Observe the applicable regulations for the operation and maintenance of potable water installations, see Regulations from section: Maintenance .
INFO!
Viega recommends actuating the fitting regularly and checking its function.
Disposal
