Swimming Pool Operation Instructions

To maintain a clean, safe and efficient swimming pool system, filtration, backwashing, rinsing and vacuuming procedures must be performed correctly. These operation guidelines ensure consistent water quality, protect public health and extend the lifespan of pool equipment.

Filtration (FILTER)

Filtration is the standard operating mode of the pool. The balance tank valve is fully opened, the main drain valve is opened between 20–50%, and the vacuum valve remains closed. The multiport valve is set to “FILTER” and the pump is started. The pressure gauge should read between 0.5 and 1 bar.

If the pressure rises by approximately 50% from the initial value, the filter is considered dirty and requires backwashing followed by rinsing.

Backwash (BACKWASH)

Over time, dirt and debris clog the pores between the filter sand grains, causing the internal pressure of the filter to rise. When the gauge reaches the yellow or red zone, backwashing is required. The multiport valve is set to “BACKWASH,” the pump is started and dirty water is discharged directly to waste.

During this operation, suction can be taken from the main drain or the balance tank.

Rinse (RINSE)

After backwashing, rinsing is necessary to prevent debris on the filter surface from returning into the pool. The valve is switched to “RINSE,” the pump is started and the operation continues until clean water appears through the sight glass.

Waste (WASTE)

When a large amount of sediment is present on the pool floor or when water must be discharged without contaminating the filter, the “WASTE” mode is used. In this mode, water bypasses the filter and flows directly to the drainage system. Pools without a natural drainage valve can also be emptied entirely using this method.

Recirculate (RECIRCULATE)

In this mode, pool water bypasses the filter and is returned directly to the pool. It is used when rapid water circulation is required without filtration.

Closed (CLOSED)

The “CLOSED” setting is used when maintenance is required on the pipeline between the pump and the filter or when the pool is taken out of service for the winter season.

Important: The pump must never be running while changing the multiport valve position.

Overflow Pool Operating Instructions

Overflow pools operate using balance tanks and channel systems to maintain proper circulation.

• Never open or close any valves while the pump is running.
• Never turn on underwater lights when the pool is empty.
• Never mix chlorine and acid in the same container.

A - Filtration Procedure

This is the daily operating mode of the pool and ensures continuous water cleanliness.

1. Stop the pump.
2. Set the multiport valve to “FILTER.”
3. Half open the main drain valve.
4. Fully open the balance tank valve.
5. Ensure the vacuum valve is closed.
6. Fully open the return (discharge) valve.
7. Close the waste valve.
8. Start the pump and check the pressure gauge.

B - Vacuuming Procedure

This procedure is used to clean dirt and debris accumulated on the pool floor.

1. Stop the pump.
2. Set the valve to “FILTER.”
3. Close the main drain valve.
4. Half open the balance tank valve.
5. Fully open the vacuum valve.
6. Fully open the return valve.
7. Open the waste valve.
8. Open the vacuum lid in the pool and connect the vacuum hose.
9. Start the pump and perform the vacuuming operation.

After vacuuming, clean the pump’s pre-filter basket thoroughly and reassemble it.

Backwash and rinse must be performed afterwards.

C - Backwash Operation

Backwashing is performed when the filter becomes dirty. It must also be carried out after every vacuuming task.

1. Stop the pump.
2. Set the multiport valve to “BACKWASH.”
3. Close the main drain valve.
4. Fully open the balance tank valve.
5. Ensure the vacuum valve is closed.
6. Close the return valve.
7. Open the waste valve.
8. Start the pump and continue until the sight glass shows clear water.

D - Rinse Operation

Rinsing must always be done after backwashing to reset the filter bed and prevent dirty water from returning to the pool.

1. Stop the pump.
2. Set the valve to “RINSE.”
3. Close the main drain valve.
4. Fully open the balance tank valve.
5. Ensure the vacuum valve is closed.
6. Close the return valve.
7. Open the waste valve.
8. Start the pump and continue until the water runs clear.

After rinsing, return the system to filtration mode.

Skimmer Pool Operating Instructions

• Do not operate valves while the pump is running.
• Do not turn on pool lights when the pool is empty.
• Never mix chlorine and acid together.
