4.0 WALL INLET VALVES
Locate the first inlet valve at a
point the farthest distance (see
Figure 6) from the Power Unit.
From this location, select
additional valve locations that
can be reached in all room
corners with a 30' hose.
Remember walls and furniture
can shorten the distance
serviced by a valve in some
areas, so be sure to locate
inlets with furniture and walls
in mind.
Alternate wall valve bracket
configurations are possible.
Nail a valve bracket (see Figure 5) to a wall stud 12" to 15" above the
floor, usually the same distance from the floor as electrical wall outlets.

5.0 VACUUM DUCT SYSTEM
(Fig. 7)
After the valve brackets are
nailed in place, drill a 2
9/16" diameter hole in the
header plate directly above
the valve bracket. Cement a
RISER tube (see Figure 5)
from the valve bracket,
extending the tube through
the hole in the header plate
for each valve.
Starting from the farthest
inlet valve (Figure 6), lay
tubing (cut-to-length) on top
of ceiling joist and work toward the Power Unit. All Tee's and Tee-Y's
must curve in the direction of air flow. Connect all risers from inlet
valves to the main duct line using only Tee-Y's (Part VM106) or sweep
Ell's (Part VM103). Cement all duct connections at the time of
installation. There cannot be any air leaks in the duct systems. TEST
of vacuum integrity with wall inlet valves installed is highly
recommended. Vacuum leaks will affect system performance.
Note: The use of nail guards (VM118) are highly recommended.
6.0 ELECTRICAL WIRING (LOW VOLTAGE)
Low voltage #18 gauge, 2-conductor cable connects all inlet valves to
the Power Unit. Hose insertion in the wall valve inlet activates Power
Unit automatically; removing the hose stops the power Unit. Low
voltage cable follows the same route as the vacuum duct system.
Secure the wiring to the horizontal main line ducts with tape or VM450
quick clips, but DO NOT tape the cable to the risers. Secure the loose
cable end at each wall bracket, allowing 6" for the wall valve connection
and 18" at the Power Unit connection.
NOTE: Two 1/4" spade lugs are required to make this installation.
