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.

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.

•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).

•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' 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 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.
