Viega Easytop 2170, Instructions For Use Manual

Page: 10 / 19

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:
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
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.
