Like the two-story house, the split level installation
commonly calls for a two-level trunk line. Here, the
power unit is located in the garage. The
intake tubing runs
exposed up the
garage wall and
into the ground
level section's
attic. Two branch
lines connect this
part of the trunk
line to inlet lines
which are dropped
inside interior walls. A
vertical branch line runs
to the upstairs attic, where
the trunk line branches into
a T-shape. This trunk line connects
to two upstairs inlet lines and to one inlet
line which drops through an upstairs wall and
down into the third-level utility room to service this
entire level. See Figure 3.

• Locate the power unit away from the general living area.
• When planning, remember the power unit is equipped with
an inlet to service a garage, basement, utility room, etc.,
wherever it is located.
• Locate the power unit in an accessible area for changing the
soil bag and periodically cleaning the secondary filter.
• Locate the power unit within six feet of a grounded electrical
outlet. The power unit requires a 120v AC power source.
• Do not locate the power unit close to a source of extreme heat
(i.e., water heater) or in an area with a high ambient
temperature (i.e., attic, furnace room).
• If the power unit is located in a closet or a small utility room,
make sure the area is well-ventilated (i.e., with door louvers).
• The power unit should be exhausted to the outside. The
exhaust should not be vented into a wall, a ceiling or a
concealed space in the house. The exhaust line should be
terminated outside the home, using Model 393 Wall Cap or a
roof vent.
WARNING: Power unit must not be mounted in a high
ambient temperature area such as attic, furnace room, etc.
LOCATING THE WALL INLETS
• Locate inlets on interior walls.
• Choose central locations which allow several rooms to be
cleaned from a single inlet.
• Locate inlets centrally so that a maximum area can be cleaned
with the 30 foot hose.
• Locate inlet within six feet of an electrical outlet to allow use of
optional current-carrying hose.
• Be sure tubing will not obstruct electrical, plumbing or other
mechanical installation.
• Be sure inlets will not be blocked by doors or furniture.
TUBING
• The installation should consist of a main trunk line running from
the farthest wall inlet to the power unit location, with branch
lines running to each additional inlet. Beginning at the area
farthest from the power unit, choose a tentative inlet location.
Measure 30 feet (for the 30-foot hose) from the proposed inlet
location to the farthest corner of the rooms to be cleaned by
that inlet to determine if inlet location is proper.
• Move tentative inlet location if necessary. Use the same
procedure to determine each additional inlet location, always
working toward the power unit.
• Generally, an installation will require 3 to 4 inlets and 16 to 20
feet of tubing per inlet. It is suggested that a floor plan be used
to more accurately determine the quantity of materials needed.
NOTE: Conventional metal or plastic strapping should
support the exhaust tubing when a muffler is used, or at
the joints of long runs of tubing where another means of
support is not available.
Model CF-380 Pipe Support is
available for this purpose.
