8A WELDING FUME EXTRACTOR
OPERATING
INSTRUCTIONS
Before commissioning the unit into continuous operation, check the
following:
1. Motor has correct speed and rotation. See arrow on fan.
2. The unit does not have any abnormal noise level and/or
vibrations.
3. No leaks in hoses or couplings.

FIGURE 1
The X-TRACTOR 8A is easy to use. It is controlled by an manual
on/off switch or automatic start/stop (optional).
1. At first start up, set the automatic start switch in manual
mode.
2. Press or turn ON the main start switch. The unit should start
up. If auto start/stop feature is connected, turn off the unit
again and switch to automatic start mode. Then press or turn
ON the main switch.
3. Activate one of the external start switches and make sure
that the machine starts.
4. Close the external switch and check that the unit is running
for the pre-set period (2 – 3 minutes). If OK, then the unit is
ready for use.
When starting the motor, the following will occur:
A. The f an/motor starts.
B. The filter cleaning receives a signal and the filter cleaning runs
according to a pre-set cycle.
C. The X-TRACTOR 8A has an off-line cleaning function. After the unit
is shut off, a number of cleaning cycles will be carried out in order
to optimize filter efficiency. The number of cycles is set by a timer
inside the cabinet. The filter cleaning switch on the front cover
must be in ON-mode. By setting the switch to OFF-mode, filter
cleaning is not performed.

AUTOMATIC FILTER CLEANING
The automatic filter cleaning system ensures optimal capacity at all
times. The system consists of a compressed air tank, solenoid valve
and a timer. The tank is filled with compressed air. The solenoid
valve opens at certain intervals set at the timer and compressed air is
blown into the filter. Dust, stuck on the outside of the filter is blown
off and into the dustbin. The tank is then again filled with compressed
air, awaiting the next cycle. This cycle can be turned off by turning
the filter cleaning switch on the front panel to OFF mode.
The ON-button shows the time the solenoid valve is open. The
OFF-button dictates the pause intervals (the time between two
cleanings). The intervals of the filter-cleaning are repeated until the
unit is turned off.
The timer is also equipped with a test button. By pressing this button,
filter cleaning is immediately performed. This should only be used as
a test. The signals for the solenoid valve are pre-set on the following
values: ON = 3 sec., OFF = 30 min. The values may be adjusted if
needed. There is a switch on the front cover where it is possible to
switch the cleaning OFF. This may be necessary when operations
where reversed air in the airstream must be avoided (i.e. - drilling of
printboard, extraction of extremely light particles etc.).
D-Lux Timer Settings
1. Time setting options;
The ON and OFF time of the D-LUX timer can be programmed
anywhere between 10ms and 99h. The set time will be indicated by
the LED display on the right side of the Digital display.
