Procedure For Filter :
- Shut off pump motor.
- Press down on valve handle, rotate valve from FILTER to BACKWASH position.
- Watch pressure gauge for back-pressure and pipe line for kinks. Be prepared to shut off pump quickly.
- After hose fills with water, run for 2 to 3 minutes or until water runs clear.
- Shut off pump motor and move multiport valve handle to RINSE position. Run on rinse for 5 to 10 seconds. Shut off pump again, and move handle back to BACKWASH. Turn on pump again until water runs clear. Continue in this fashion 3 to 4 times, alternating between backwash and rinse, to ensure a thorough backwash.
- Shut off pump motor and move multiport valve handle to FILTER position.
- Turn pump back on and note lower pressure.
Procedure For Softener :
- Always press the handle down before turning the handle to the desired position viz. Service, Regeneration or Rinse.
- If the line pressure is more, it is advisable to close the inlet valve before turning handle.
- Ensure that minimum 2kg/cm2 pressure is available for getting optimum ejector performance.
- If there is a suction problem even at 2kg/cm2 then the ejector filter screen may be clogged with dirt etc. For cleaning this, the bolts connecting the upper and lower housing of MPV have to be removed, after disconnecting/closing the inlet. Then remove the filter and wash and clean it and refit reassemble the MPV.
