5. Then 'A' appears on the display - do not press anything.
6. After a few seconds the unit will resume operation with factory

OFF-LINE FILTER CLEANING
When the X-TRACTOR 3A is off, the signal to the solenoid valve is
controlled by an additional timer placed inside the cabinet. This timer
keeps the signal on for a certain period of time in order to run two or
three more cleaning cycles after the extraction unit is shut down
(OFF-line cleaning). Inside the filter container, there is a cover that
closes the inlet in order to avoid dust being blown out in the
duct/hose system.
FIGURE 4
The timer is pre-set at the factory to the values in the following table.
Normally it is not necessary to adjust the timer.
