12.2 Location
Before installing the ManaBloc, review the following
instructions.
NOTE: The ManaBloc is much like an electrical
breaker box. When a xture needs repair, the line
to that xture 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.
COLD WEATHER CAUTION! The thermoplastic
components of the ManaBloc, like all
thermoplastics, have decreased resistance to impact
under freezing conditions and can be damaged.
Care must be exercised when installation occurs in
freezing conditions.
BEFORE INSTALLING THE MANABLOC, MAKE SURE
THE LOCATION REQUIREMENTS HAVE BEEN MET.
Take extra caution when handling the ManaBloc
in temperatures that are below freezing. Tubing
penetrations may require sleeving or the installation
of an insulator.
1. UNDER NO CIRCUMSTANCES shall the ManaBloc
be located in a permanently covered area (behind
sheetrock, plywood, paneling) or where freezing
temperatures may occur. Do not install in direct
sunlight. THE MANABLOC MUST BE ACCESSIBLE
and there shall be sufcient clear area in front of the
ManaBloc to provide access.
2. When local code allows, mount the ManaBloc
unit in a re-rated wall, provided an access door
meeting the same rating requirements as the wall is
installed over the access opening.
3.
When installing the ManaBloc in a location
other than between studs, provisions must be
made to support the tubing runs as they exit the
ManaBloc. (See “15.3 Bending ViegaPEX Ultra
tubing” on Page 43).
4. Any installed cover panel shall allow access to
the ManaBloc and its mounting screws, the port
valves, distribution line connections and supply
line connections.
5. To maximize potential water and energy savings,
the ManaBloc should be mounted as close as
is practical to the hot water source, taking the
following into consideration:
a. When the ManaBloc is mounted above the
water heater, there shall be a minimum of 36"
of connecting tubing between the water heater
and the ManaBloc to reduce the chance of
heat stacking.
