For PEX Press connections:
The water supply to the ManaBloc and
the port valves shall be turned off before
attempting installation of press adapters.
Use only sealing elements
supplied with the adapters.
1. Ensure sealing element (A) is in place and
the tool locator ring (B) is present in its
factory-installed position.
2. Square off tubing to proper length and
insert the tting fully into the end of the
tubing as shown. Full insertion means
tubing must be completely visible in
at least two viewing holes and may be
partially visible in one.
3. Place the PEX Press tool jaw over the
attached press sleeve, resting it against
the tool locator ring. Press the sleeve
with an appropriately sized press jaw.
DO NOT PRESS TWICE. Refer to current
Viega PEX Water Systems Manual for
additional pressing information.
4. Remove tool locator ring (B) and slide
swivel nut (C) over tubing as shown.
5. Ensure sealing element (A) is in place and
clean of any dirt or debris. Wet sealing
element with tap water.
6. Insert the tting into the desired port until
the tting ange sets ush with the end of
the port.
7. Thread the swivel nut (C) onto the ManaBloc
port. Hand-tighten only. Open the port
valve(s) before turning on the main water
supply.
Hand-tighten only!
UNDER NO CIRCUMSTANCES
shall any form of thread sealant
(Teon
®
paste, pipe dope, etc.) be
used on distribution line connections.
The carriers present in these compounds can
crack the plastic port connections, resulting
in leaks and water damage.
