Operation
WARNING: Check the vacuum cleaner and the power cord each time before using them. A damaged
appliance must not be used. There is a danger of injury.
ATTENTION: Only use the vacuum cleaner with all filters intact, in dry condition, and correctly placed.
Make sure that the openings of the vacuum cleaner are not clogged or obstructed. Otherwise, the vacuum
cleaner might be damaged.
NOTE: Your vacuum cleaner is equipped with a safety switch to prevent overheating. It automatically
cuts off the power supply if the motor is overheated. In this case, switch the vacuum cleaner off and
disconnect it from the outlet. Remove the cause of the overheating. Wait for about 45 minutes. After it
has cooled off, you may use the vacuum cleaner again.
Your vacuum is also equipped with a motor bypass valve. The purpose of this feature is if your vacuum
bag is too full, the filters are too dirty, or if there is a clog in the vacuum the valve opens. When the valve
opens it allows air to enter the motor chamber, reducing suction to the hose but making certain the motor
does not overheat and burn up. The Prolux Phantom is a high-end vacuum designed to last many years.
This feature protects the motor and allows it to be used for many years to come. When the motor bypass
valve opens you will notice less suction and a different sound. When this happens turn the vacuum
OFF and unplug the cord from the electrical outlet. Then solve the problem by changing the bag,
and filters or removing any clogs.
