Press connection with SC-Contur
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:
with the wet leakage test in the pressure range from 1.0–6.5 bar
with dry leakage test in the pressure range from 22 mbar–3.0 bar
Sealing elements
NOTICE!
Only EPDM sealing elements are permitted in drinking water installations. Other sealing elements may not be used.
The model is factory-fitted with EPDM sealing elements.

Information for use
Corrosion
Uncovered pipes 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
Contact with aggressive chemicals
in aggressive surroundings
If external corrosion protection is required, the following regulations should be followed:
DIN EN 806‑2
DIN 1988‑200
DKI information publication i. 160
INFO!
Easytop fittings made of gunmetal are suitable for all types of drinking water.
The chloride concentration in the medium must not exceed 250 mg/l.
This chloride is not a disinfectant, but in fact pertains to the content in sea and table salt (sodium chloride).

-
Attach the protective sleeve in front of and behind the cladding (e. g. sheetrock or Fermacell panels) with lock nuts.
-
Seal wall lead-in on the front side of the wall with the self-adhesive sealing flange.
Actuate 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 (load and leakage test) before commissioning.
This test is carried out on a unit that is finished but not yet covered.
The general rules of engineering must be observed.
e.g. the following regulations apply:
DIN EN 806–4
Data sheet "Leakage tests of drinking water installations with compressed air, inert gas or water"
The result must be documented.
Maintenance
NOTICE!
Inform your customer or the operator of the drinking water installation that the system has to be maintained on a regular basis.
DIN EN 806‑5 must be observed for the operation and maintenance of drinking water installations.
INFO!
We recommend actuating the fitting regularly and checking its function.
Disposal
Separate the product and packaging materials (e. g. paper, metal, plastic or non-ferrous metals) and dispose of in accordance with valid national legal requirements.
