Setup and Installation

Proper setup is crucial for the optimal performance and longevity of your sand filter pump. Follow these steps carefully.

1. Site Selection

Choose a level, firm surface near your above-ground pool, ensuring it is protected from direct sunlight and adverse weather conditions. The location should allow for easy access for maintenance and operation.

2. Assembly of Filter Tank and Base

1. Place the base support on the selected level surface.
2. Carefully place the 16in filter tank onto the base support, ensuring it is stable.

3. Adding Filter Media

This filter system is compatible with both filter sand and filter balls. Refer to the table below for recommended capacities.

Image: A graphic illustrating the recommended capacities for filter media: 100 lbs of sand or 4.6 lbs of filter balls.

• For optimal filtration, use 100 lbs of filter sand (not included) or 4.6 lbs of filter balls (not included).
• Ensure the filter assembly (standpipe with laterals) is correctly positioned inside the tank before adding media.
• Add the filter media slowly to avoid damaging the laterals.

4. Connecting the 6-Way Valve and Pump

1. Attach the 6-way valve to the top of the filter tank using the flange clamp, ensuring a tight seal with the O-ring.
2. Connect the pump to the filter tank using the provided hoses and adaptors. Ensure all connections are secure to prevent leaks.
3. Connect the pool's skimmer line to the pump's inlet and the pool's return line to the valve's "RETURN" port.

5. Pre-Filter Assembly

The integrated pre-filter helps capture larger debris before it reaches the main filter, protecting the pump and enhancing filtration efficiency.

Ensure the pre-filter basket is properly seated within its housing before operating the pump. The clear lid allows for easy visual inspection of debris accumulation.

Operating Instructions

Familiarize yourself with the 6-way valve functions and the programmable timer for effective pool maintenance.

1. 6-Way Valve Functions

The multi-port valve allows for various operational modes. Always turn off the pump before changing valve positions to prevent damage.

Image: A diagram illustrating the six positions of the multi-port valve: Filter, Backwash, Rinse, Waste, Closed, and Recirculate, with brief descriptions of each function.

• FILTER: Normal filtering mode. Water passes through the sand media, cleaning the pool.
• BACKWASH: Reverses water flow through the filter to clean the sand bed. This expels trapped debris out the waste port.
• RINSE: Used after backwashing to flush out any remaining dirty water from the valve and filter, settling the sand bed.
• WASTE: Bypasses the filter and sends water directly out the waste port. Useful for vacuuming heavy debris or lowering pool water level.
• CLOSED: Shuts off all flow to the filter and pump. Never use while the pump is running.
• RECIRCULATE: Bypasses the filter and circulates water directly back to the pool. Useful for mixing chemicals without filtering.

2. Programmable Timer

The integrated 24-hour programmable timer allows for automated filtration cycles, ensuring consistent water clarity and energy savings.

Image: A close-up of the pump's control panel, showing the digital display and buttons for setting the 24-hour programmable timer. It highlights "Step 1 Set running hours" and "Step 2 Turn on the pump".

1. Set Running Hours: Use the control panel to program the desired daily filtration duration.
2. Activate Pump: Turn on the pump. The timer will automatically manage the filtration cycles based on your settings.
3. The time you activate the timer becomes the daily start time for the programmed cycle.

Maintenance

Regular maintenance ensures the longevity and efficiency of your LANCHEZ sand filter pump.

1. Backwashing and Rinsing

Backwash the filter when the pressure gauge reads 8-10 PSI above its normal operating pressure, or when pool water clarity decreases significantly.

1. Turn off the pump.
2. Set the 6-way valve to BACKWASH.
3. Turn on the pump and run until the water from the waste port runs clear (typically 2-3 minutes).
4. Turn off the pump.
5. Set the 6-way valve to RINSE.
6. Turn on the pump and run for 30-60 seconds.
7. Turn off the pump.
8. Set the 6-way valve back to FILTER.
9. Turn on the pump to resume normal filtration.

2. Pre-Filter Basket Cleaning

Regularly inspect and clean the pre-filter basket to prevent debris buildup and maintain optimal pump performance.

1. Turn off the pump and disconnect power.
2. Carefully remove the clear lid of the pre-filter housing.
3. Remove the filter basket and empty any collected debris (hair, leaves, gravel).
4. Rinse the basket thoroughly with water.
5. Reinsert the clean basket and secure the clear lid, ensuring a watertight seal.
