Eureka Vacuum System Cleaner - Manual (Page 5)

Inlet Valves
Each inlet valve has electrical contacts which activate the power unit motor when the hose is connected and in use. The sys-
tem shuts off as soon as the hose is removed or turned off.
An obstruction in the inlet valve may cause the power unit to continue to run after the hose is removed from the inlet. Check
all the inlet valves and remove any obstruction to shut down the power unit.
When unplugging the hose from the inlet valve, hold the inlet cover open for a few seconds to allow the suction to decrease
and protect the inner seal.

Performance Indicators - Power unit motor is operating at peak or optimum performance when all five power bars
are illuminated. Normal operating performance is when three to five bars are shown. Fewer bars will be illuminat-
ed as performance decreases. Display will illuminate operating performance of the last operating cycle during sleep
mode. Note: It is normal to see changes in performance when specialty cleaning tools are used. Performance lev-
els will decrease as the filter is loaded with debris or as the motor has significant wear.
Clean Filter Indicator - The cloth filter installed in the power unit may require occasional cleaning based on the
amount of usage and type of debris vacuumed. The Clean Filter Indicator will light when the power unit senses a
loss in power that will affect cleaning performance. When Clean Filter Indicator is lit, remove and clean filter as
shown in “How to Maintain” section of Owners Manual.
Call for Service Indicator - The Call For Service Indicator will light when the power unit reaches a period in the
life cycle when motor brushes and filter should be checked for wear. Contact your nearest service station/dealer for
proper service to avoid major maintenance costs.
Hours of Service Indicator - The Hours of Service Indicator shows hours of machine usage. When the last bar is
flashing service is urgently required.
HOW TO MAINTAIN
The instructions given in the booklet serve as a guide to routine maintenance. Proper airflow or suction can be maintained
by keeping the dirt receptacle and filter clean and the plastic pipe and hose free from clogs. Check the Home Maintenance
Guide at the end of this booklet for suggestions before calling for service.
Dirt Receptacle and Filter
Reduced airflow or suction indicates the built-in vacuum system is not operating at maximum efficiency: If the dirt recepta-
cle is full and the filter is clogged, no air can pass through the unit and no cleaning can take place.
Empty The Dirt Receptacle
NOTE: Disconnect power cord from electrical outlet before removing the dirt receptacle.
Some models feature see-through windows on the receptacle to tell at a glance when the receptacle needs to be emptied; on
other models the receptacle must be removed. To remove the receptacle, grasp the handles and turn the receptacle to the
left. Remove and empty the contents. Return the receptacle and turn to the right. Be sure the receptacle is securely attached
to avoid any suction leakage.
Filter and Disposable Bag
If the disposable paper bag is full or a filter is clogged, no air can pass through the unit and no cleaning will take place.
Remove and dispose of the paper bags.
SOME MODELS FEATURE A DISPOSABLE PAPER FILTER BAG WITH CLOTH FILTER
NOTE: Disconnect power cord from electrical outlet before cleaning the filter.
The elbow with the paper bag adapter must be installed, locked in its L slots, in the body facing downward as shown for the paper bag.
1. Hold the bag collar with fingertips and align the bumps in the adapter with the bump cutouts in the collar.
2. Insert adapter and push the bag collar all the way up to the lip on the elbow.
3. Rotate the bag collar 45˚ counter clockwise so the bumps on the adapter
DO NOT align with the collar bump cutouts. Replace the bucket, turn to lock.
4. To remove, rotate the bag collar 45˚ clockwise and gently lower the collar
off of the bag adapter.
