Sample chamber illumination

Fig. 18: The sample chamber is illuminated by one or two flu-
orescent tubes (model MSC 0.9, 1.2, 1.5, 1.8). The spring-loa-
ded sockets of the fluorescent tube [2] are installed to the light
dome mounting frame in the sample chamber.
1. Switch the device off, disconnect it from the power supp-
ly system and protect it against accidental reconnection.
2. Move the front window down all the way beyond the frame
(SmartClean position) to ensure a sufficient gap between
window upper edge and light dome.
3. The fluorescent tubes are retained by rotatable sockets.
Rotate the tube carefully by 90° into the removal position
and remove it from the socket.
4. Insert the new tube und rotate it into the contact position.
10.2.2

Optional UV lamps

Fig. 17: The optional, device-integral UV lamp [1] is installed
to the sample chamber ceiling immediately behind the front win-
dow. The UV lamp should be replaced after 1500 operating
hours.
1. Switch the device off, disconnect it from the power supp-
ly system and protect it against accidental reconnection.
2. Move the front window to the maximum opening position.
3. Wear protective gloves to prevent skin fat residues from
burning into the lamp tube.
The UV lamp is installed in rotating sockets. To remove, ro-
tate the lamp counter-clockwise to disengage the latch and
remove it from the sockets.
4. To install, slide the lamp contact pins into the rotating so-
cket grooves and rotate the lamp clockwise to latch the so-
ckets.

Retrofitting and repairs

External communication systems, e.g. failure report systems
or components for supplying media such as gas solenoid val-
ves, can be retrofitted and integrated into the device control.

NOTE – Retrofitting and repairs!
All retrofitting and repair works are interfe-
rences with the safety system of the device.
Particularly modifications to the filter system
and resulting changes of the airflow may im-
pair personal and material protection. Such
work must be carried out only by authorized
service personnel.
