AKM 345 Gen2 Instruction Manual

12. Maintenance

For the below mentioned executions, a regular control is suggested and if so required, also
certain maintenance.

12.1. Protection Class IP 65

To eliminate the risk of condensation build up inside the instrument, the instruments are
provided with two desiccant capsules. These can get saturated after a time in operation and
a replacement will become necessary. The colour of the gel will change from pink (when
new) into white (after saturation). If condensation is occurring inside the instrument,
replacement of the capsules will be necessary; part number - 47126.
12.2. Mountings with Rubber Dampers - Seismic Type and Universal
Type
The vibration dampers on these mountings are made of Natural Rubber, NR, (also called
Isopren). The expected life time of these parts is estimated to be a minimum of eight years.
Since Natural Rubber will age faster when exposed to direct sunlight, high ambient
temperatures or corrosive environments, we recommend a regular check of these parts.
When the rubber dampers become old they should be replaced.
Please also note that it is important to mount these parts without any torsional
stress.
