DETERMINE LOCATION FOR INLET VALVES
2.2 Inlet valves placed next to doors or in hallways generally provide maximum cleaning coverage, making it
possible to clean three or four rooms from a single inlet valve.
NEL Naat
To
determine
the
location
for the
first inlet valve,
stand in an area farthest away from the power unit
with a 25' or 30' length of string or cord. Use a 25'
length if standard accessory set will be used (or 30'
for the deluxe set). Check to see that the intended
location will give access
to all corners
in the area,
keeping
in
mind
that
the
cleaning
hose
must
negotiate furniture and other obstructions.
Work back toward power unit, adding inlet valves as
needed
following the same
procedure.
Wall
inlet
valves are most often used and should be placed
about the same height and within two feet of an
electrical outlet. If for some reason tubing cannot
be installed in the wall, the same
inlet valve can be
installed in the floor.
PLANNING TUBING SYSTEM
The tubing system consists of two sections — the
main vacuum line which runs from the farthest inlet
valve to the power unit and the branch vacuum line
to the other inlet valves.
2.3 When
planning
tubing
routes,
determine
the
easiest way to reach the inlet valve locations from
above or below. Drops and risers will usually be
installed
inside
partition
walls
and
a hole
will
need to be drilled for the tubing in the header or
the floor plate.

2.4 The main vacuum line can be installed in the
basement
at ceiling
height
with
branch
lines
running
through
the
floor
plate
or
partitioned
wails to inlet valves.

2.5 The main vacuum line can be run through the
attic with branch
line connections
made
in the
attic and dropped down through the header plate
of partitioned walls to inlet valves. Care must be
exercised
when
drilling
through
fire
stop
transverse
partitions.
In an
attic without
a floor,
the main line can be laid across the ceiling joists
and strapped in place.
Multi-level Homes
Where possible, it may be easier to drop second
floor
branch
lines
through
closets,
a
laundry
chute, cold-air return or behind built-in appliances.
