Installation Options
Install in the return line after the filter, before water flows back to the pool. Two wiring options are supported.
With Dry Contact
Link the Dry Contact signal to the pump and/or pool cover so chlorine is produced only while the pump runs. Best for pools with a control panel or automation system.
Without Dry Contact
Power the unit through an RCD and circuit breaker, working together with the pump timer. Best for standard pools without a central control system.
Electrical installation should be carried out by a qualified technician, including an RCD as shown in the manufacturer's wiring diagram.
