sized according to the fixture demand
and the length of the individual line
(see the MANABLOC Tube Size Guide
for details on sizing a typical system).
A MANABLOC with all of the same
size ports, can easily have some ports
converted to 1/2" with optional PEX
Crimp adapter MXLSA33 (3/8" port to
1/2" tube).
Conversely, 1/2" ports can be
converted to 3/8" with optional PEX
Crimp adapter MXLDC24, or PEX
Press adapter MXPDC24 (1/2" port
to 3/8" tube).
Note: Each port converted to a larger
or smaller size requires one adapter
and one PEX Crimp ring or PEX Press
sleeve (sold separately).

4.5 Location
Before installing the MANABLOC,
review the following instructions.
NOTE: The MANABLOC is much like
an electrical breaker box. When a
fixture needs repair, the line to that
fixture may be shut off at the
MANABLOC, eliminating the need to
shut down the water supply for the
entire house.
This feature requires that the
MANABLOC be accessible after
installation.
1. Under no circumstances shall the
MANABLOC be located in a
permanently covered area (behind
sheetrock, plywood, paneling),
where freezing temperatures may
occur, or in direct sunlight. THE
MANABLOC MUST BE
ACCESSIBLE and there shall be
sufficient clear area in front of the
MANABLOC to provide access.
2. When local code allows, the
MANABLOC unit can be mounted
in a fire rated wall provided the
access door meets the same rating
requirements as the wall and is
installed over the access opening.
