3.1 I Operating principle
The filter is essential for a swimming pool since it contributes to water treatment and ensures its clarity.
Water passes through the filter media in the filter vessel and impurities are removed.
The greater the accumulation of impurities, the more the pressure in the filter will increase. Identify the normal operating
pressure on the pressure gauge when turning on. When the pressure r0.3 to 0.5 bar (+4 to 7 psi) relative to the
normal operating pressure , the filter media must be cleaned by backflushing.
3.2 I Multiway valve positions
Position "Filter"
Water is sent to the filter media and returned to the pool.
: Pool suction = open
: Pool discharge = open
: Filter inlet or outlet = open
: Discharge to the drainage system = closed
Position "Backwash"
The filter media is backflushed. The water circulation direction in
the filter is reversed and the water discharged to the evacuation to
eliminate the impurities.
: Pool suction = open
: Pool discharge = closed
: Filter inlet or outlet = open but reverse direction of flow
: Discharge to the drainage system = open
Position "Rinse"
Water is sent to the filter media and sent to the evacuation. This is
carried out to complete the washing procedure and settle the filter
media in the filter, as well as to clean the filter pipes after backflushing.
: Pool suction = open
: Pool discharge = closed
: Filter inlet or outlet = open
: Discharge to the drainage system = open
