9. FILTER
OPERATIONS
Start Up
Once the filter system has been properly assembled, the sand chamber filled with sand and the hoses connected, you may begin
with filtration. However, we recommend that you clean and prepare the new sand that is in the sand chamber first. Cleaning the sand
prior to filtering your pool will remove most of the dust and tiny sand particles that may exist in the sand. If you move straight to
filtering, these particles will end up in your pool.
Cleaning the Sand
1. Disconnect the pump from the power source.
2. Start with the multi-port valve in the “Closed” position.
3. If you haven’t done so already, fill your pool with water. Ensure that the water level is at least 1 – 2 inches above the top of the
hose intake and return ports in the pool.
4. Release the shut off valve at the intake port in the pool. If you plugged the intake port, remove the plug to allow the water to flow
into the intake hose.
5. With the filter-pump system installed in a location level lower than your pool’s water level – water will automatically flow into the
pump-filter system.
6. Allow the filter tank to fill with water.
7. Check for leaks and make any necessary adjustments.
8. Follow the backwash process below.
Backwash Process
1. Disconnect the pump from the power source (if not disconnected already).
2. Attach backwash hose (not included) to backwash port.
3. Place the multi-port valve in the “Backwash” position.
4. Reconnect to the power source.
CAUTION
See Section 5, Power Source Requirements
5. Run filter in backwash mode until discharge water is clear.
6. Disconnect the pump from the power source.
7. Place the multi-port valve in the “Rinse” position.
8. Reconnect to the power source.
9. Allow filter to run for 60 seconds to remove any remaining residue from pump and valve.
10. Disconnect the pump from the power source.
11. Place the multi-port valve in the “Filtration” position.
12. Reconnect to the power source.
Your filtration system is running and ready for further operation.
NOTE:
When the filter pump is properly connected to the power source, the pump will begin to push the
water through the bed of sand and out of the backwash hose. In this process, water will be drained from
your pool as it cleans the bed of sand within the tank. You may want to put a garden hose in the pool to
add water while the pump is running so that the water level does not fall below the intake return ports.
While the sand is being cleaned, run your fingers through the water exiting the backwash hose. When
you can no longer feel or see sandy grit in the water, the sand cleaning process is complete.
Backwash Do's and Don'ts
Be aware and make note of the filter pressure when the sand is clean. Backwash when you see an increase of 5–10 psi on the
pressure gauge.
• Do backwash long enough to get the job done right. Let the system backwash until the water exiting the waste line is clear.
Note that backwashing can remove 50–300 gallons of water from your pool so pay attention. Also, be aware of local codes
regarding pool water disposal as some communities outlaw drainage.
• Don’t backwash excessively. Sand filters operate more efficiently during mid-cycle. Some level of debris in the sand bed
actually helps filtration and makes the filter more effective. Too much backwashing will reduce efficiency.
• Don’t vacuum the pool in backwash mode. This can plug up the strainer at the bottom of the filter which will result in
inefficient operation. In addition, you may have to remove all of the sand to get it unclogged.
