30.2 Measuring free chlorine
About this task
To ensure that the Planmeca ActiveAqua water treatment system functions
properly and that the settings are on an optimal level, the free chlorine in the
outcoming water must be measured weekly.
When help message H90.1 is displayed, measure the concentration of free
chlorine in the water using test strips.
Steps
1. Use the syringe to fill half a cup with water.
2. Immerse a test strip in the water and carefully swirl the test strip around
for 30 seconds.
3. Take out the test strip and compare its colour with the colour chart on the
test strip bottle.
4. On help message H90.1 on the control panel, select the chlorine level
according to the measurement and press OK.
The chlorine level alternatives are < 0.2 (low), 0.2 - 0.8 (optimal), and >
0.8 (high).
Based on these measurements, the dental unit automatically adjusts the
electrolysis strength in normal use, which in turn affects the chlorine
level.
Results
If the water does not contain enough chlorine (value < 0.2), perform long
instrument flushing and measure the free chlorine concentration again.
For instructions on how to perform long instrument flushing, see section
"Long instrument flushing" on page 215.
If the chlorine level is continuously too low, raise the value of
Electrolysis
strength in normal use
in the
ActiveAqua maintenance
window. If raising the
value does not help, contact service.
For information on functions performed in the
ActiveAqua maintenance
window, see section "Adjusting Planmeca ActiveAqua settings" on page 258.
