Locating The Power Unit; Locating The Wall Inlets; Tubing - NuTone CV-350C Instructions D'installation

THE SPLIT-LEVEL HOUSE
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
EXHAUST
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. This last inlet services
both the utility room and a large L-shaped recreation room.
Refer to Figure 3.

LOCATING THE POWER UNIT

• Locate the power unit away from the general living area.
• The power unit is equipped with an inlet. When planning,
remember the power unit as an inlet for a garage, basement,
utility room, etc.
• 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 120 vAC power source.
• Do not locate the power unit close to a source of extreme
heat (i.e., water heater) or in an area with an ambient high
temperature (i.e., attic, furnace room).

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' hose.

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 a 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.

UNIT
• 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 a 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.
• 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.
• 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.
