VALVE OPERATION
The operation and the positions of valve settings are as follows:
Valve Settings
Filter (also during vacuuming)
Back Wash
Recirculate
NOTE: Always "STOP" pump when changing selector valve position.
INITIAL START - UP
1. Make sure the correct amount of media is in the filter tank.
2. Prime pump.
3. Set valve handle in BACK WASH position.
4. Start pump and operate in BACK WASH cycle for three (3) minutes. This will purge the filter of excess
fines in the media.
5. Turn pump OFF and set valve handle to RINSE. Start pump and run for one (1) minute.
6. Stop pump and set valve handle to FILTER. Restart pump. System is now operating on a normal FILTER
cycle.
7. Adjust the valves in the skimmer and main drain lines (if provided) to achieve balanced flow rates.
8. When a pool is filled initially, the filter may have to be BACK WASHED once a day until the water becomes
sparkling clear. From that point on, BACK WASH when pressure gauge indicates 30 to 40 kPa higher
than at starting pressure.
OPERATIONAL & INSTALLATION TIPS
1. Always turn pump "OFF" before changing valve positions.
2. Never run pump dry as it depends on water for lubrication.
3. Always maintain minimum water level to ½ way up the skimmer mouth.
4. Clean pump strainer regularly.
5. Maintain a proper chemical balance in the pool.
6. Maximum operating pressure is 250kPa on RX Series and 140kPa on E-Series.
7. Ensure pressure gauge on valve is positioned so that rain water cannot collect on glass face.
8. Back wash filter regularly for 3-5 minutes each time to ensure sand is completely cleaned.
