6.6.8 Surfaces
IMPORTANT: Do not attempt to decontaminate any part of the instrument before
shutting it down and unplugging it from the power source.
Before plugging the instrument back in and turning it on, always wait 15 minutes
to allow the disinfectant to evaporate – Danger of fire and explosion!
For safety reasons, only authorized customer service personnel may decontaminate
the power pack!
Regularly decontaminate all outside surfaces of the instrument, including all covers (for
example, printer cover, bottle compartment cover, top cover). For these tasks, use the
decontaminant in accordance with local regulations.
Very dirty surfaces should first be cleaned with swabs or paper towel of gauze that have been
soaked in distilled water. Spray all removable covers (top cover, bottle compartment cover)
with surface disinfectant and then wipe them down with swabs or paper towel of gauze.
Always respect the time necessary for proper effects.
IMPORTANT:
Never spray parts that cannot be removed or that are inside the instrument!
