6.2.1 Compression
Connections
(3/8" & 1/2" ports)
THE WATER SUPPLY TO THE
MANABLOC SHALL BE TURNED OFF
WHILE MAKING DISTRIBUTION LINE
CONNECTIONS.
NOTE: The red caps on the
MANABLOC designate hot ports, the
blue caps designate cold ports. Make
sure the distribution lines are being
connected to the correct ports (hot or
cold). The use of color coded
ViegaPEX tubing also reduces the
possibility of cross connections.
1. For each distribution line, slide the
Lock-In compression nut (A), Lock-
In insert (B) and the plastic ferrule
(C) onto the tubing in that order.
See illustration below.
The long taper of a 3/8" ferrule (C)
must be TOWARD THE END OF THE
TUBE; a 1/2" ferrule is symmetrical
and may be installed facing either
direction. Insert the stainless steel
stiffener (D) COMPLETELY into the
end of the tubing.
WARNING: DO NOT attempt
to install the Lock-In insert
backwards as breakage may
result. ALWAYS insert the long portion
of the insert sleeve over the tube first.
DO NOT attempt to use or reuse
inserts that are defective, cracked,
broken or otherwise damaged, as
connection failure will result.
2. Push the tubing into the port socket
(E) until it bottoms out.

Holding the tube so that it does not
back out of the fitting, slide the
white Lock-In insert and ferrule
s
nugly against the chamfer inside
the port socket.
While holding the tube against the
bottom of the socket, thread the Lock-
In compression nut onto the port and
tighten hand-tight.
3. While holding the tube securely to
prevent turning, finish tightening the
nut with the MANABLOC Wrench
(Viega Part No. MW1) until the
white Lock-In insert appears
between the lugs and becomes
flush with the ends of the lugs, plus
1/4 to 1/2 turn.
Complete the connection as soon as
each distribution line is connected to
the MANABLOC.
WARNING: DO NOT use
slip-joint pliers to tighten the
Lock-In nuts. Use the MW1
MANABLOC Wrench to tighten the
compression connections.
4. After all connections are complete,
recheck that all of the Lock-In
inserts are visible between the lugs
and are flush or protruding slightly
beyond the lugs.
5. As the distribution lines are
connected to the MANABLOC, they
should immediately be labeled on
the cover plate as to which fixture
that line supplies.
Fixture labels are included with each
MANABLOC. Affix the appropriate
label to the cover plate next to the
port.
Each valve should be
turned to the open
position after completing
each connection.
LUG
COMPRESSION
CONNECTION CAUTION
This plumbing system relies
u
pon the proper tightening of
distribution line compression
connections.
Failure to properly complete ALL
connections will result in failure.
Incomplete or improper connections
can hold pressure during a system
test but will fail at a later date,
resulting in water damage.
DO NOT OVERTIGHTEN.
Compression fittings can be
OVER TIGHTENED.
Overtightening of the Lock-In
compression nuts may cause damage
to the tubing, nut, valve or fitting body.
DO NOT tighten Lock-In nuts beyond
the recommendation of these
instructions (Step 3).
6.2.2 PEX Press Connections
(1/2" ports)
THE WATER SUPPLY TO THE
MANABLOC AND THE PORT VALVES
SHALL BE TURNED OFF BEFORE
ATTEMPTING INSTALLATION OF
PRESS ADAPTERS.
CAUTION
Use only sealing elements
supplied with the adapters.
1. Slide the supplied swivel nut (D)
and a press sleeve (C) 61000 for
3/8" tubing; 61020 for 1/2" onto the
tubing (threads of the nut toward
the end of the tubing).
Insert the barbed end of the fitting (B)
fully into the end of the tubing as
shown.
