Cleaning of the water must be done when pressure differential across 0.5 kg/cm2.

Install the strainer in the main line after sand filter vertically / horizontally. Inlet should be on top side & outlet at the top. Provide proper support to ensure it does not vibrate due to water pressure.

Ensure ball valve is fitted before inlet of strainer.

Follow closing instructions as at'd' above.

To start the flow opens the flush valve gradually and slowly.

Ensure recommended pressure at inlet and slowly.

Filter element should be cleaned regularly on time by opening flush and closing outlet.

Clean element talking it out flush valve and closing outlet. Clean element talking it out under water tenderly & periodically.

Water soluble fertilizer and pesticides should be given through ventury. Strong chemical should not be poured into filter directly as it will affect filter element.
