8. Maintenance & troubleshooting
8.1 Maintenance instructions
For maintenance by qualified personnel, the device must be opened, cleaned and
inspected at the given locations, as well as possible, without any hazard being
posed to maintenance personnel or other persons. Proper precautions must be
taken before cleaning and removal of wearing parts. This includes locally filtered
forced-air ventilation in the area in which the device is being maintained, and
proper personal protective gear.
During maintenance or repair work, all soiled objects that can no longer be
adequately cleaned must be disposed of. Such objects must be discarded in an
impermeable bag in compliance with applicable regulations for disposal of such
refuse.
If necessary, the device can be cleaned with a damp cloth.
It must never be cleaned with flowing water.
The operator is obligated to have maintenance performed once per year.
During maintenance, the entire system is to be tested by a trained expert for
correct operation. A log is to be kept of the main annual inspection in the
included maintenance book. It must document the date of inspection,
deficiencies determined and the name of the inspector. The date of the next
inspection can be read from the test plate installed on the device.
