Like the two-story house, the split level installation
commonly calls for a two-level trunk line.

Here, the power unit is

The intake tubing runs
exposed up the

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.
See 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 has an inlet for a garage, basement,
utility room, etc.
• 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.
• 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).
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.
• 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.
• 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.
• 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 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.
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.
• Move tentative inlet location if necessary. Use the same

WALL INLET ROUGH-IN
1. Once the locations for wall inlets have been determined,
mount all inlet brackets.
2. To locate bracket on wall stud, measure approximately 18" up
from finished floor level. (Height may vary according to
individual preference.)

to side of stud so that front edge of bracket is flush to front of
stud. (The bracket may also be nailed to the front edge of the
stud. For front stud mounting, use locating tabs on bracket for
proper alignment.)
4. Refer to Figure 5. Model 329 for use with 330 inlets. Remove
cardboard from plaster guard frame. Using four (4) provided
screws, attach the appropriate flanged fitting and inlet seal to
back of inlet.
5. Replace cardboard in plaster guard frame.
6. When using Model 329 glue elbow to mounting plate.
NOTE: Configuration of spacer may vary depending upon
installation.
NOTE: When using the Model 361 inlet bracket on walls
thinner than 1⁄2", use a 1⁄4" spacer (not furnished) between
the wall and the inlet bracket. See Figure 5A.
Spacer may be made from plywood, masonite, etc. Contact
cement may be used to hold spacer in place during assembly.

4. Branch lines should always join the trunk line from above or
from the same level. Never join a branch line from an angle
below the trunk line.

5. Before cementing, pre-assemble section to inlet fitting, check
for proper length.
6. Refer to Figure 10. Apply cement (Model 379) to outside of
tubing. Coat tubing approximately 1" back. Take care to keep
cement from inside of tube.
7. Refer to Figure 11. Insert tubing into fitting with a twisting
motion to evenly spread cement. Be sure tubing is firmly
seated in fitting.
8. If fittings have been attached to tubing at the end opposite the
inlet bracket, be sure alignment is proper before cement sets.
9. Refer to Figure 12. Low voltage wiring (Model 376) should
be completed as tubing is installed. Tape wire to tubing to
hold in place and insert through hole in inlet bracket.

NAIL PLATE INSTALLATION
Caution: When tubing is run through the wall stud, sole
plate, headers - or anywhere that building materials will be
attached - place a nail plate (Model 378) over that area
(on both sides if necessary) to prevent nails from piercing
tubing.

1. Once the walls have been finished, install the wall inlets.
2. Remove the cardboard plaster guard.
3. Refer to Figure 13. For some dry wall or panel construction,
the plaster frame will extend beyond the finished wall. In this
case, remove plaster frame from mounting bracket by
removing mounting screws.
4. Refer to Figure 14. Connect 2-conductor low voltage wire to
terminal screws on back of wall inlet.
FIGURE 13

5. Guide excess wire back through hole in inlet bracket and
make sure seal is secure between mounting bracket and
flanged fitting.
6. Refer to Figure 15. Place inlet into mounting bracket and
secure.
NOTE: When wall inlets are installed in 1/2" thick walls or
less, the tube of the wall inlet may extend into elbow area of
the flanged fitting and cause blockage. Shorten the wall
inlet tube to prevent this condition. See Figure 16.
For extra thick walls, use Model 399 extension sleeves to
connect inlet to the flanged fitting.

Grounding Instructions – This appliance must be grounded. If
it should malfunction or breakdown, grounding provides a path of
least resistance for electric current to reduce the risk of electric
shock. This appliance is equipped with a cord having an
equipment-grounding conductor and grounding plug. The plug
must be plugged into an appropriate outlet that is properly installed
and grounded in accordance with all local codes and ordinances.
Danger – Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. Check with a
qualified electrician or service person if you are in doubt as whether
the outlet is properly grounded. Do not modify the plug provided
with the appliance – if it will not fit the outlet, have a proper outlet
installed by a qualified electrician.
This appliance is for use on a nominal 120-volt circuit and has a
grounding plug. Make sure that the appliance is connected to an
outlet having the same configuration as the plug. No adapter
should be used with this appliance.
1. Connect low voltage wire (18 gauge, 2-conductor, Model 376) to
two low voltage wires located on outside of the power unit.
2. The power unit is equipped with a six foot grounded cord. Plug
cord into 120 volt grounded receptacle.
