Maintenance and Prevention
Equipment from Kontron Technology India requires only minimum servicing and maintenance for problem-free operation.
For light soiling, clean the VRack 4U with a dry cloth.
Stubborn dirt should be removed using a mild detergent and a soft cloth.
Clean the filter mat regularly (see chapter 10.1 “Cleaning the Filter Mat”).
10.1.
Cleaning the Filter Mat
The filter mat (Fig. 21, pos. 2, Fig. 25) is inserted in the filter mat holder (Fig. 21, pos. 3, Fig. 23) at the front side in front
of the fans (Fig. 22, pos. 2). The soiling of the filter mat is caused by the pollution of the operating environment. A
heavily soiled filter mat can cause excessive heating of the device. For this reason we recommend to clean the filter mat as
often as necessary. The filter mat can be changed during operation of the system.

pos. 5).
3.
Pull the filter mat holder out of the positioning holes (Fig. 22, pos. 3) into the marked direction (see Fig. 21) and lift
it off.
4.
Remove the soiled filter mat (Fig. 21, pos. 2 and Fig. 25).
5.
Clean the filter mat as follows:
Rinse in water (up to approx. 40°C; possibly with the addition of a standard mild detergent).
It is also possible to beat the filter pad, to vacuum it or blow it with compressed air.
For dirt that contains grease/oil, the filter pad should be rinsed with warm water with the addition of a degreaser.
Filter pads should not be cleaned with powerful water jets or wrung out.
