30.3 Changing Planmeca ActiveAqua prefilter
About this task
The prefilter's lifetime depends on the water hardness setting and the clean
water consumption, the maximum change period for the prefilter being 25
weeks.
A counter keeps track of the change period. Change the prefilter when the
dental unit displays help message H90.2.
CAUTION
To ensure the proper operation of the dental unit, it is important that you
change the prefilter when help message H90.2 is displayed and do not reset
the prefilter change period counter until the prefilter has been replaced.
NOTE
It is very important that the water hardness value has been set correctly in
the Planmeca ActiveAqua settings to ensure proper operation of the
Planmeca ActiveAqua water treatment system and to prevent calcification of
the Planmeca ActiveAqua electrolysis chamber.
Steps
1. Switch off the dental unit.
2. Open the cuspidor door.
3. Remove the prefilter.
Hold a paper towel under the prefilter at removal, as some water will
drop from the filter head. Detach the prefilter by first rotating it in the
direction shown below and then pulling it downward.
4. Attach the new prefilter by first placing it into position and then rotating it
in the opposite direction until it locks into position.
5. Switch on the dental unit.
