Hold the mounting plate in place with a bent
coat hanger. Open the valve lid and slide the
valve flange first over the end of the coat hang-
er. Keep ten-
sion on the coat
hanger while
inserting the
valve into the
mounting plate
with a twisting
motion (See
Fig. 11). Do not
use glue; the
built in mount-
ing plate gasket
will provide a
positive seal.
Align the screw
holes in the valve with those in the mounting
plate. Using the screws provided, secure the
valve in place. Use the extra short screw if the
longer is going to interfere with the tubing
behind. Do not over tighten.
Apply glue to an adequate length of tubing and
aim it upwards through the hole and into the 90
degree dual elbow fitting on the back of the
mounting plate. Join this branch line to the trunk
line using a 90 degree sweep tee.
If the inlet valve is to be serviced from the attic,
shorter pieces of tubing joined by couplings
may be required due to overhead space restric-
tions. Precut these pieces and work quickly to
prevent the on the end of the tubing from drying
before it reaches the fitting at the valve below.
d) Floor Valves
To install a floor inlet, drill a pilot hole with a coat
hanger and check the location as previously
described. When you are sure that the pro-
posed location will not be blocked by a joist or
other obstruction, cut a hole in the carpet slight-
ly larger than your 2-1/4" (5.7cm) drill bit. Drill a
2-1/4" (5.7cm) hole in the floor. Chisel or saw
this hole larger to accommodate the inlet valve
low-volt connections (Fig. 12).
Assemble an adapter reducer bushing and
some low-volt wire to an inlet valve. Screw the
valve to the floor. Repeat until all inlets are
installed (Fig. 13).
e) Closet Wall Installation—Existing
Structure
Often it is only practical to install your system
with the line coming up through the floor inside
a closet and
then through
both sides of
the wall. To use
this method,
select suitable
inlet valve
location, exer-
cising same
precautions as
for normal wall
i n s t a l l a t i o n .
Using a length
of coat hanger,
pierce a hole
through both
walls (Fig. 14).
