Initial Setup - Davey Promatic ESC-pH SYSTEM Supplément Au Manuel

14. Connect clear tube from the chemical containers then fit tube as described previously.
15. Ensure that hydrochloric acid is diluted by 1 Part Acid to 2 Parts water, if using Sulphuric
Acid it must be no greater than 10% strength.
16. Please ensure that you change the Tube in the pump module every 6 months.
INITIAL SET-UP
1. After installation leave pH Control off and run pool pump for an hour. While this is being
done it is a good time to ensure that the pool balance is correct.
2. Using a pool test kit measure the pH.
3. Using the tool supplied adjust CAL until the pH display matches the test kit result. The
display will alternate between pH and the chlorine cell production so this may take a little
time to get right.
4. Switch the pH Control to SET and adjust to the desired pH if necessary. NOTE: for
concrete pools it is possible that a pH set point of around 7.4 or below will lead to high
acid consumption and frequent additions of buffer. To reduce this effect a set point of 7.7
may be more economical. Refer your pool professional for further advice.
5. Switch pH Control to RUN and allow unit to operate.
6. Retest pool pH with test kit over the next few days to fine tune control if necessary
