Inlet Hole
Make a hole in the board material for the inlet valve as shown in the figure.
The size of the rectangular opening should be 2 3/8" x 4 3/4" (60mm x
110mm). In existing houses where tubes are routed underneath, a hole can
be drilled for the tube using a guide hole as a template. Glue the 90° inlet
elbow onto the sleeve of the mounting bracket. Leave a gap of approxi-
mately 5/8" (15cm) for the low-voltage cable to be connected to the inlet
valve. Then the dust tube is glued into the inlet elbow.
Do not disconnect the mounting screws
completely. Loosen them enough to fit
the low voltage cable around them and
then tighten.

Strip off approximately 1" (2cm to 3cm) of the insulation from the end
of the low-voltage cable. Roll the end of the cable two turns around the
screws in the inlet valve and tighten the screws.
Screw the inlet valve into the mounting bracket and make sure that the
screw does not extend through the tube. If necessary, use shorter screws.
In a complete wall structure, the mounting bracket is held in place by a
hook as shown in the figure.
Installation in a Brick or Concrete Wall
When installing the inlet valve, sink the pipes, the inlet elbow, and the
mounting bracket in the wall so that the highest surface of the mounting
low voltage cable bracket is approximately 1/4" (5mm) deeper than the final inner surface.
For the tubing system, make a 3 1/8" x 3 1/8" (80mm x 80mm) channel
in the brick or concrete wall independent of the final thickness of the wall.
The tubing installation must be sturdy enough so that tubes and parts
do not move out of their positions later during the installation work. It is
recommended to cover the opening of the inlet valve to protect it from cast
material.
