13 HP Air Purifier System
2 Operation
2.1 Operating cconditions
The APS must be operated in a vibration-free, dry and as far as possible dust-free location.
The APS must be operated in a work area receiving adequate ventilation.
Under no circumstance operate the APS in a closed room without ventilation.
The air temperature must be in a temperature range between + 5 °C and + 35 °C.
The relative humidity in the air may not exceed 70 %. Condensation from humidity on the sur-
faces of the APS must be avoided.
2.2 Operation
The APS is controlled via its membrane control panel with transparent display ( Fig. 1). All the
functions of the APS will be controlled from this panel.
The basic setting will be displayed in the transparent display when the machine is switched on:
– On the left the total hours of operation on the installed filter element.
– In the middle the actual filter saturation given as a percentage of full capacity.
– On the right: fan speed as a percentage of the maximum. The minimum value is
set to 20%.
You will find the following control elements on the membrane control panel of the APS:
ON/OFF button
The ON/OFF button is used for switching the APS on and off. When switched on
you can hear the fan start and the air will be extracted from the printer.
If you change the values (e. g. fan speed), then these settings will be saved when
the unit is switched off. When it is switched on again the APS will continue to ope-
rate with these settings.
ENTER bbutton
This button is only to be used by your service technician for control work and adjust-
ments to the electronic control of the APS (e.g. after replacement of the filter ele-
ments).
If nothing is entered/changed for several seconds, the display automatically returns
to the basic setting.
