2. Safety Information

Always follow basic safety precautions to reduce the risk of injury, fire, electric shock, or property damage.

• Electrical Safety: Ensure the pump is connected to a grounded outlet protected by a Ground Fault Circuit Interrupter (GFCI). Do not operate the pump if the power cord is damaged.
• Water and Chemical Safety: Never operate the pump without water. Always turn off the pump before performing any maintenance or adjustments. Handle pool chemicals with care and follow manufacturer instructions.
• Pressure Safety: The filter operates under high pressure. Do not attempt to open the filter or service the pump while it is running. Ensure all clamps and connections are secure before operation.
• Children: Keep children away from the pump and filter area.
• Installation: Install the pump on a solid, level surface, away from the pool edge, ensuring proper ventilation.

4. Setup and Installation

4.1 Placement

Position the filter pump on a firm, level surface, preferably concrete or a sturdy base. Ensure it is located below the pool's water level for optimal priming and within reach of a grounded electrical outlet. Allow sufficient space around the unit for maintenance and access.

4.2 Adding Filter Media

1. Remove the multi-port valve from the top of the filter tank.
2. Cover the standpipe opening inside the tank to prevent sand from entering.
3. Carefully pour the recommended amount of filter sand (typically 50 lbs) or filter balls (1.5 lbs) into the tank.
4. Ensure the sand/filter balls are evenly distributed.
5. Remove the standpipe cover and clean any sand from the tank's rim.

4.3 Connecting Hoses

1. Attach the multi-port valve to the filter tank, ensuring a tight seal.
2. Connect the pool's skimmer/drain hose to the pump's inlet.
3. Connect the pump's outlet to the multi-port valve's 'PUMP' port.
4. Connect the multi-port valve's 'RETURN' port to the pool's return jet.
5. Connect a backwash hose to the 'WASTE' port if desired.
6. Use the provided 1.5-inch or 1.25-inch hose adapters and clamps to secure all connections.

4.4 Priming the Pump

Before starting, ensure the pool is filled to the proper level and all valves are open. The pump must be primed by filling it with water until water flows out of the return line. This removes air from the system and prevents dry running.

5. Operating Instructions

5.1 6-Way Multi-Port Valve Functions

The multi-port valve allows you to control the water flow for different operations. Always turn off the pump before changing the valve position.

• FILTER: Normal filtering mode. Water flows through the filter media and returns to the pool.
• BACKWASH: Reverses water flow to clean the filter media. Water is discharged through the waste port.
• RINSE: Used after backwashing to flush out any remaining dirt from the filter media before returning to FILTER mode. Water is discharged through the waste port.
• WASTE: Bypasses the filter, sending water directly out the waste port. Useful for vacuuming heavy debris or lowering pool water level.
• RECIRCULATE: Bypasses the filter, circulating water directly back to the pool. Useful for chemical distribution without filtering.
• CLOSED: Shuts off all flow to the filter and pump. Use for pump or filter maintenance.

5.2 Setting the 24-Hour Programmable Timer

The integrated timer allows you to automate filtration cycles for 2 to 24 hours. Refer to the timer's specific instructions for detailed programming steps. Generally, you will set the desired operating duration and the start time. The pump will automatically turn on and off according to your settings.

5.3 Starting the Pump

1. Ensure the pump is primed and all connections are secure.
2. Set the multi-port valve to the 'FILTER' position.
3. Plug the pump into a grounded GFCI outlet.
4. Turn on the pump. Water should begin to circulate.
5. Check the pressure gauge. A rising pressure indicates the filter is collecting debris and may require backwashing soon.

6. Maintenance

6.1 Backwashing and Rinsing

Backwash the filter when the pressure gauge reads 8-10 PSI above its clean starting pressure, or when water flow to the pool noticeably decreases.

1. Turn off the pump.
2. Set the multi-port valve to 'BACKWASH'.
3. Turn on the pump and backwash until the water running through the sight glass (if present) is clear (typically 2-3 minutes).
4. Turn off the pump.
5. Set the multi-port valve to 'RINSE'.
6. Turn on the pump and rinse for 30-60 seconds.
7. Turn off the pump.
8. Set the multi-port valve back to 'FILTER' and restart the pump.

6.2 Filter Media Replacement

Filter sand typically needs replacement every 3-5 years, depending on usage and water quality. Filter balls may last longer but should be inspected annually. Refer to the filter media manufacturer's guidelines.

6.3 Winterization

Before freezing temperatures, drain all water from the pump, filter, and hoses. Disconnect and store the pump and filter in a dry, protected area. Remove the pressure gauge and drain plugs from the filter tank.
