4.1 Outside
Cooling System on Level 4
To ensure maximum cooling capacity the heat sink must be kept clean.
Cleaning
Level 3 and 4 including our industrial keyboards are all resistant to most chemicals on their
outside surfaces. You can even use solvents for cleaning if necessary.
4.2 Inside
Filter for Level 3
Level 3 versions are equipped with a fan placed on the lower part of the back and an air
grid on the upper part (see page 51 level 3 back).
The fan brings air out which is coming in at the air grid. This let the air into the display
compartment. The air grid is covered by a filter. It is recommendable to clean the filter so
the dust doesn’t build up. The filter can easily be removed by unscrewing the 4 nuts at the
grid. Use soap water for cleaning. How often this should be done depends on the environ-
mental factor and for how long periods the PC is switched on. The premaintenance indica-
tor on the front or the premaintenance software package will indicate if fan speed becomes
too low.
