NOTE: If the dosing volume is set to 0.0 (ml) the peristaltic pump will remain off.
NOTE: In the event of power loss: the programmed settings (dosing volume
and dosing time) will remain stored. If the power to the controller is switched
off for longer than 3-Hours the current time will need to be re-programmed,
this is indicated to the operator by the clock flashing.
Set Dosage Requirements:
Please note: Dosage amounts are set in ml/day (millilitres per day)
Use the below reference table as a guide.
To calculate your pool volume see page 26-27 at the rear of this manual.
NOTE: The above table is based on dosing Hydrogen Peroxide (H₂O₂) with a 32%
concentration and a water temperature of 28⁰C.
For a concentration of 12% the above dosing amount should be multiplied by 3
(i.e. the dose for a 50m³ pool would need to be increased to 960ml/day when the
H₂O₂ strength is 12%).
For any other concentration strengths, the dose amount should be adjusted pro-
rata as required. The digital controller will automatically sense the temperature of
your water and adjust the required dose accordingly.
B. Dosing Liquid Chlorine
Refer to table B for suggested Liquid Chlorine dosing figures.
