9) Use a garden hose or bucket to fill the media tank with water.
10) Clean mineral tank threads to remove any filter media. Uncover distributor tube and reinstall control
valve by threading it securely onto the mineral tank. (O-ring seal: HAND TIGHTEN ONLY!)
11) Attach bypass (Figures 2 & 3) to control valve body.
12) Re-attach drain line to control valve.
13) IMPORTANT: Activated Carbon, Filter Ag and Birm must be soaked for at least 2 hours prior to
submitting it to full flow rate to prevent loss of media to drain.
14) Open the bypass valve only 1/4 of the way to the "Service" position (Figure 3, Page 4). Any air trapped
in the media bed should begin purging to the drain and water should begin flowing slowly to the drain.
15) Once the air is purged, fully open the bypass valve to the "Service" position (Figure 3, Page 4) and
leave the control valve in "Backwash" position for at least 10 minutes or until water flowing from the
drain line runs clear; whichever is longer.
16) Plug the power cord back into an un-switched electrical outlet.
17) Manually advance the control valve to the "Service" position (Figure 4a) by turning the Manual
Backwash Knob clockwise. Check for and resolve any leaks in the unit or connected plumbing.
