in Step 5 to the insides of the stud
cavity using a square and pencil.

the marking procedure on the adjacent stud.
13. Drill ¾" holes through both studs at
each marked location. Be sure to
hold the drill level, perpendicular to
the stud to prevent drilling holes at an

made during drilling.
14. Mark and drill any holes for main
water supply and hot water supply/
return lines at this time. A 1¼" bit will
provide adequate clearance for ¾" or
1" tubing. The tubing shall enter and/
or exit the ManaBloc in a straight line
so as not to induce bending stress
on the ManaBloc. Necessary elbows,
couplings, and tees are allowed in the
main water supply lines.
Drill ¾" holes for
distribution lines,
1¼" holes for
supply lines.
15. Reattach the ManaBloc to the
mounting straps.
When the ManaBloc is installed
prior to wall 󶈵nishing operations,
the unit MUST be protected from
paint, texture compounds, and drywall dust.
