Cleaning
5.3.1
Ventilation pads
The dust filters consist of fine metal mesh. These filters cannot be exchanged but are meant to be cleaned with a
vacuum cleaner from time to time.
There are two procedures to clean the filters. The first procedure can be chosen, if it is possible to have a vacuum
cleaner at the NGC-105. The second procedure explains how to remove the front cover and take it away for
cleaning.
Vacuum-cleaning the filters on the device
If the device is not operating while being cleaned, the front flap can simply be cleaned with the vacuum cleaner.
During operation there is strong suction on the filter mesh. Therefore the flap must be opened to remove the
suction on the filter mesh before cleaning.
•
Open the front flap by unscrewing the screws [5] on the top of the front, please refer to
Figure 3-1
.
•
Use a vacuum cleaner to remove the dust from the filter mesh. It is advisable to vacuum-clean the flap from
both sides, outside and inside, to receive good results.
•
Close the front flap again.
Removing the front flap for cleaning
The front flap can easily be demounted from the NGC-105 and taken to a place where it can be cleaned more
easily.
•
Open the front flap by unscrewing the screws [5] on the top of the front, please refer to
Figure 3-1
.
•
The hinges of the front flap are established with an angular bolt at each side, please see the figure below. It
is additionally hold by a chain.

Opened front flap with fixation elements
•
Unscrew the knurl screw [1] to remove the chain from the front flap. Take care, the front flap is then no
longer supported and it might be necessary to retain it.
•
The bolts [2] are pressed outwards by springs. To remove the flap press both bolts together and turn them
upwards into the strap hinges [3]. This releases the front flap from the hinge.
•
Now you can carry the flap to a location where you want to clean it.
•
Use a vacuum cleaner to remove the dust from the filter mesh. It is advisable to vacuum-clean the flap from
both sides, outside and inside, to receive good results.
•
Reinstall the front flap and close it again.
