Some models have a "check bag" indicator on the

outside of the bag door. Fig, 4

The cleaning tool hose attaches to the cleaner

through the top of the hood and CAN stay attached

at all times.

When using cleaning tools, the nozzle control must

be in the #5 cleaning tools position. Fig, 5

Withthe nozzlecontrol inthe number 5 position, a

valve gate in the main body closes and blocks all air

flow from the agitator cavity therefore diverting it to

the hose.

Set on carpet, positions 1-4, the gate valve is

opened allowing air to flow from the agitator cavity

to the motor. Fig, 6

To ensure maximum efficiency in the 4 floor cleaning

positions .b_o_Lb_hose ends must be firmly connected

to the cleaner base and tool rack Fig, 7 or the hose

removed completely and the tool door closed.

Note;

Only the components that

distinguish the Dirt Finder

unit from the Dimension

are listed.

I. General

These uprights are lightweight upright vacuums

that feature high performance computer design

motors, double edge cleaning, quick release cord

wraps and top conversion cleaning tools

All models have automatic height adjustment in

that the nozzle is free to float up and down on the

carpet. These models additionally have front

wheel height control to limit the minimum nozzle

height which allows the user to "select the proper

setting for optimum operation on various types of

carpets.

The Legacy and Legacy II models use Type "A"

top-fill disposable bags.

The Dimension/Dirt Finder uses Type "Z" top-fill

disposable bags.

Microfiltration bags are available for both models.

II. Operation

These cleaners operate on a Dirty Air System

principle, i.e., dirty air passes through the motor

area (fan) before reaching the bag.

=o CLEAN AIR

,o DIRTY AIR

As illustrated, air and dirt are sucked through the

molded agitator housing and directed into the

motor area. The fan then propels the air and dirt

up the handle passage and into the throw-away

bag.

The Legacy units are controlled by an on/off switch

located on the side of the unit. (Fig. A)

The Legacy II, Dimension and Dirt Finder units are

controlled by an on/off switch located in the front of

the upper handle. (Fig. B)

NOZZLE CONTROL

KNOB _,_

It is important that the unit be in the proper setting

(carpet - for floor cleaning, and cleaning tools -

when using the hose and tools). This will ensure

optimum performance.

The cleaning tool hose attaches to the unit through

the tool door located on the top of the hood. The

air is directed to the hose by adjusting the nozzle

control knob to the cleaning tool position.

The valve gate operates in conjunction with the

height adjustment lever. When the lever is in any

one of the four carpet settings the valve gate is

open. The cam is not contacting the valve gate.

Note: These illustrations are shown without the

bottom plate or wheel assembly in place.

Dirt Finder feature:

The embedded Dirt Finder system is powered by a

regular 9V alkaline battery. The battery is located

in a holder inside the bag compartment.

The circuitryis energized when the cleaner on/off

switch istumed to the on position. Aseparate

switch mounted in the bag housing is actuated by

a raised rib on the upper switch rod.

Amicrophone, located near dirt duct, senses

debris that strikes the tube and signals the circuit

board which controls the lights.

The green light signifies clean and the red dirty.

It is important to note that when you turn on the

unit the red light will come on. After afew seconds

the rod light will go off and the green light will come

on. This function lets you know the Dirt Finder

feature is ready. If this lighting pattern does not

occur check the troubleshooting portion of this

:instruction.
