8. OPERATIONAL INSTRUCTIONS

8.1 PH CONTROL

In a swimming pool application, control of the water's pH is essential in order to allow Chlorine to
correctly and efficiently oxidise pathogens in the water. The Davey Lifeguard's HOME SCREEN (refer
Figure 8.1) shows the current pH of the pool water, as measured from the Davey Lifeguard's pH probe.
Figure 8.1
This can also be observed from the dashboard of the Davey Lifeguard app (refer Figure 8.2).

8.1.1. Adjusting pH set point

The factory default pH set point is 7.4, however you may wish to change this once the Davey Lifeguard is
installed. It should be noted that Chlorine's effectivity is greatly influenced if pH levels are too high, or too
low. Davey recommends following the pool chemistry levels shown in Section 10. Adjustments to pH set
point can be made as follows.
