3.4 Interrupting the Press Cycle
Take the Viega Z3 Actuator Off the Press Ring
In the event that the current press cycle must be interrupted, you can manually
loosen the press tool from the press ring.
▶
Press the black manual release button on the handle of the press tool until the
piston has fully retracted and the actuator is no longer stress loaded (see the
manual for the press tool used).
▶
Open the Z3 actuator.
Continuing an Interrupted Press Cycle
Interrupted presses of MegaPress 2½" to 4" press fittings can be restarted. This
should only be done in extenuating circumstances where the press ring was
manually loosened.
Before and during the press stroke of the resumed pressing, note that
the empty stroke is longer and in particular note the following:
■
The ball heads of the hinged actuator must lie correctly in the contact
points of the press ring.
■
The press ring must be correctly seated and lay flush on the press fitting.
