4. Setup Instructions

Proper setup is crucial for the pump's performance and longevity. Follow these steps carefully:

4.1 Pre-Installation Checks

• Compatibility: Ensure your existing sand filter system, hoses, and electrical supply are compatible with the pump's specifications (3/4 HP, 115V, 60Hz).
• Hose Size: Verify your pool hoses are either 1.25 inches or 1.5 inches in diameter to use the included adapters.
• Location: Place the pump on a solid, level surface, close to the pool and filter system. Ensure it is protected from direct sunlight and harsh weather, and has adequate ventilation.
• Electrical Outlet: Confirm a dedicated, GFCI-protected 115V outlet is available within 6 feet of the pump.

4.2 Connecting the Pump

1. Attach Adapters: Select the appropriate hose adapters (1.25-inch or 1.5-inch) for your hoses. Securely attach them to the pump's inlet and outlet ports.
2. Connect Hoses: Connect the pool hoses from your skimmer/main drain to the pump's inlet (suction side) and from the pump's outlet (discharge side) to your sand filter system. Use hose clamps to ensure tight, leak-free connections.
3. Electrical Connection: Once all plumbing connections are secure and the pump is primed, plug the pump into the GFCI-protected 115V outlet.

4.3 Priming the Pump

Before initial startup or after any maintenance that drains the pump, it must be primed:

1. Ensure all valves are open to allow water flow from the pool to the pump.
2. Remove the clear lid of the prefilter basket.
3. Fill the prefilter basket and pump housing completely with water.
4. Replace the lid, ensuring it is tightly sealed to prevent air leaks.
5. Turn on the pump. It should begin to draw water and expel air. If water does not flow within a few minutes, turn off the pump, re-prime, and check for air leaks in connections.

5. Operating Instructions

Your choosmo pool pump features a built-in timer for convenient, automated operation.

5.1 Initial Startup

• After successful priming and electrical connection, the pump is ready for operation.
• The pump will start running immediately if the timer is not set or is in manual mode.

5.2 Setting the Built-in Timer

The timer allows you to automate the pump's daily run cycle. Refer to the timer interface on the pump for specific button functions.

1. Access Timer Settings: Locate the timer control panel on the pump.
2. Select Run Time: Choose from 9 available run-time settings, ranging from 2 to 24 hours. Each setting corresponds to a specific duration the pump will operate daily.
3. Activate Schedule: Once a run time is selected, the pump will begin its daily schedule at the time it was set. For example, if you set a 6-hour run time at 9:00 AM, the pump will run for 6 hours daily starting at 9:00 AM.
4. Manual Override: Most timers include a manual override option to run the pump continuously or turn it off outside the programmed schedule. Consult the timer's specific instructions for this function.

Regularly check the timer settings, especially after power outages, to ensure your pool maintains its filtration schedule.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your pool pump.

6.1 Cleaning the Prefilter Basket

The built-in strainer basket collects debris and should be checked and cleaned regularly, depending on pool usage and debris levels.

1. Turn Off Power: Always disconnect the pump from the power source before cleaning.
2. Release Pressure: If applicable, open any air relief valves on your filter system to release pressure.
3. Remove Lid: Unscrew and remove the clear lid of the prefilter basket.
4. Remove and Clean Basket: Lift out the basket and empty any collected debris. Rinse the basket thoroughly with water.
5. Inspect O-Ring: Check the lid's O-ring for cracks or wear. Lubricate with a silicone-based lubricant if dry.
6. Reassemble: Place the clean basket back into the housing, ensuring it seats correctly. Replace the O-ring and lid, tightening securely to prevent air leaks.
7. Re-prime: Follow the priming steps in Section 4.3 before restarting the pump.

6.2 Winterization

For regions with freezing temperatures, proper winterization is essential to prevent damage:

• Disconnect Power: Turn off and unplug the pump.
• Drain Water: Disconnect hoses and open drain plugs (if any) to completely drain all water from the pump.
• Store: Store the pump in a dry, frost-free location.
