NOTE:
To close, turn the slot so that it is
across the direction of flow.
Caution:
In the case of the versions with
check valve and non-return valve, these are
already pre-assembled with a tightening torque
of 15 Nm (hand-tight). If the tightening torque
is too high, this will destroy the valve screw con-
nection and the O-ring.
When installing the valve, use a wrench to pre-
vent it from turning!
In the case of the Star-Z 15 APress version, only
use Viega pressure clamps. Other pressure
clamps would destroy the pump.
