The water then passes through the filter elements to the outlet manifold for consumer use. Description of the Backwashing Process The controller transmits an electrical command to the first solenoid according to either differential pressure or time.
- Page 4 Spin Klin Technology- Spin Klin Spine General: The Spin Klin discs are stacked on the Spin Klin spine. The discs are color-coded by micron size, and are assembled according your water filtration Filtration Mode Backwash Mode requirements. The spine assembly has a spring compression unit and an internal piston which are used to alternately compress and release the discs during filtration and backwash cycles.

- Page 7 Spin Klin – System Maintenance Monthly Maintenance Check inlet /outlet pressures: In case the pressure differential is above 5 m / 7 Activate automatic backwash of the Spin Klin filter battery. In the event that the pressure differential remains high check for possible failures. Check for leakages from the drain manifold: In case there is a leakage of water during the filtration stage, check for possible failure at the backwash valve seals.
