Notes
1. The
Chemflo
controls ORP within a 20 mV “control band”. If the Set Point is 700 mV, the
Chlorine pump will start when the reading drops to 680 mV and stop again when the reading
reaches 700 mV. The control band stops the pump being rapidly switched on and off when the
reading is close to the Set Point, thereby increasing the pump’s life.
2. The exact ORP Set Point to achieve the correct Chlorine level will vary depending on other
chemical factors such as pH, Alkalinity and Cyanuric Acid (stabiliser) levels.
It is imperative that the pool water is checked regularly to ensure that all other chemical
parameters are correct.
3. When first installing the
Chemflo
, check the Chlorine levels every few days using a Chlorine
test kit. Increase the ORP Set Point if the Chlorine level is low and decrease it if the Chlorine
level is high. Once the pool has been fine-tuned over a week or two, the controller will
accurately maintain the correct Chlorine level.
