- Avviate a pompa: Restore power to the pump at the circuit breaker and turn on the pump.
- Purga l'aria: Allow the filter tank to fill with water. Once a steady stream of water (not air) emerges from the air relief valve, close the valve.
- Verificate per e fughe: Inspect all connections and the filter tank for any signs of water leaks. Address any leaks immediately.
- Monitor Pressure: Note the initial operating pressure on the filter gauge. This is your clean filter pressure. A rise of 8-10 PSI above this reading typically indicates that the filter needs cleaning.
Mantenimentu
Regular maintenance is crucial for efficient filtration and extending the life of your filter module.
Cleaning the Filter Module
The filter module should be cleaned when the pressure gauge reads 8-10 PSI above the clean operating pressure, or if water flow to the pool/spa decreases significantly.
- Shut Down System: Follow steps 1 and 2 from the 'Setup and Installation' section to safely shut down and open the filter housing.
- Remove Module: Carefully remove the outer filter module from the filter manifold.
- Risciacquare: Use a garden hose with a spray nozzle to thoroughly rinse the pleated material. Spray from top to bottom, working between the pleats to dislodge debris. Do not use a high-pressure washer, as this can damage the filter media.
