Enlarge the hole in the exterior wall to accommodate
the inlet valve assembly (valve and mounting bracket).
(As described above in “Installing an inlet valve.”)
Inside the closet, drill a pilot hole through the fl oor
beneath the opening in the wall or at a convenient
spot nearby to check for obstructions. If there are no
obstructions, cut a 2-1/4" (5.7cm) hole through the
fl oor. Run low-voltage wire through the hole in fl oor,
and through the wall to exterior of closet.
Pass low-voltage wire through the wire guide hole in
the inner wall closet assembly (Fig. 02) and tape low-
voltage wire to this assembly immediately behind the
bracket. Attach wires to low-voltage terminals on the
back of the inlet valve. Place the inner wall assembly
lengthwise through the wall opening and arrange the
assembly so the bracket is fl ush with the inside
surface of the wall. Screw the inlet valve to the wall
(Fig. 03).
Floor valve installation.
To install a fl oor inlet valve, drill a pilot hole with a
wire coat hanger and check the location as previously
described. When you are sure that the proposed location
will not be blocked by a joist or other obstruction, cut
a hole in the carpet slightly larger than your 2-1/4"
(5.7cm) drill bit. Drill a 2-1/4" (5.7cm) hole in the fl oor.
Enlarge the opening to accommodate the low-volt
connections. Assemble an adapter reducer bushing
and attach the low-volt wire to the inlet valve. Drop the
low-volt wire to the basement. Screw the valve to the
fl oor. Repeat until all inlets are installed.
Multi-story homes.
Multi-story homes usually require one or more inlets
on each level. Instead of trying to line up inlet valves
from one level to the next, run a separate line of
tubing from the upstairs inlet valve to a branch line
or to the main trunk line (Fig. 04).
In a two-story home, upstairs beneath the site you’ve
selected for the inlet valve, cut a hole just large
enough to allow you to reach the second-fl oor sole
plate. Hint: Cut the hole low in the wall for easier
drilling through the sole plate. Cut a 2-1/4" (5.7
cm) hole in the sole plate. Install the inlet valve just
as before. Then, from the basement, insert a length
of tubing long enough to reach through the hole in the
second fl oor sole plate to the site for the inlet valve.
You may have to join several lengths of tubing.
Measure and pre-cut these pieces and test-fi t them
before gluing. When you do apply glue, work quickly
to prevent the glue at the top end of the tubing from
drying out before it reaches the fi tting at the inlet valve.
