7. OZOMATIC ® 24 HOUR CIRCULATION SYSTEMS;
It is possible to use an Ozomatic in a 24 hour per day circulation system.
The systems are used mostly on spa’s and require a dedicated spa suction and outlet. That is, the system is
independent of the main pumps and blower.
In order to fit a 24 hour Circulation System you will need to have access to the spa under-side. A spa suction
must be fitted low in a footwell, and a spa return fitted just above the level of the suction. Make sure that the
return does not direct water into the suction.
The spa suction must be plumbed to the inlet of the Low Power Pump (Circ Pump), which drives the High
Efficiency Injector and then returns to the spa. The High Efficiency Injectors are available from Davey Water
Products. Other fittings will need to be purchased from a Spa/Pool Shop Dealer. Please note that isolation valves
should be fitted at the spa suction and return to allow service of the pump/injector without draining the spa.
A slightly less efficient method is to use a Footwell Injector in place of the Spa Return. In this case a High
Efficiency Injector is not needed. Isolation valves remain in place.
The Low Power Pump, High Efficiency Injector and Mini Footwell Injector all use 20mm (3/4”) connections.
Flexible 20mm (3/4”) tubing should be used for all equipment - the Spa Suction/Return will need to be reduced
down to this size.
