9. RECOMMENDATIONS AND CHECKLIST FOR PROPER USE OF THE EQUIPMENT
The venturi system (injector), as shown in Figure 1, is equipped with a check valve comprised of a stainless steel spring
and a Teflon (PVDF) ball. The principal function of this system is to prevent water from flowing back to the
Ozone
Generator
. The check valve should be checked regularly, as particles can be deposited in the valve and prevent it from
working properly.
A check valve can be installed after the bypass system, in order to ensure that water does not flow toward the
Ozone
Generator
equipment. The system is also equipped with a pressure gauge
(see Figure 4)
to indicate the working
pressure, which should be 3-4 bar.
No maintenance whatsoever should be done on the
Ozone Generator
equipment when it is connected. If maintenance
is necessary, the customer must ALWAYS contact the nearest authorized technical service.
The
Ozone Generator
equipment should ONLY be run when the filter pump and the pressure pump (70/5; 70/7 or
120/7) are running. It should never be operated when either one or both of these units are off (OFF position).
Since ozone is a volatile molecule, it leaves no residue. In addition, the pool treatment system normally does not
operate for long periods during the day.
Public pools MUST keep a small amount of residual chloride or bromide in the water, or use algecide.
Private pools SHOULD keep a small amount of residual chloride or bromide in the water, or use algecide.
When the ozonation equipment is off (particularly for extended periods), the PVC ball valve for ozonated air inlet to the
venturi should be closed as a safety measure.
Check the pressure pump (depending on the model) as indicated in the instruction manual. A contactor must always be
installed with the respective relay, as an electrical and operational safety measure. The 70/5, 70/7 and 120/5 pumps
only work in fresh water and not in seawater. For seawater operation, please consult an authorized technical service.
Please refer to the AstralPool technical guidelines on water problems and the basic chemical concepts of water
(hardness, alkalinity, algae, chemicals, etc.) for an overview of water treatment, as all concepts are highly interrelated.
Check that water is chemically balanced, particularly in terms of pH, alkalinity.
10. BASIC TROUBLESHOOTING AND SOLUTIONS
Color in the PVC glass tubing may be due to:
Disinfection is poor because the ozonation equipment is not running.
There is no small disinfectant residual (chloride or bromide).
The pH of the water is poorly adjusted.
The general pilot does not turn on.
No power is being supplied to the equipment.
The indicator bulb is blown.
