1)
Pressure must be relieved on water treatment system by turning the bypass valve to the bypass position. Then initiate an immediate manual back-
wash cycle as described on Page 4-3.
2)
Disconnect the power cord from the electrical outlet.
3)
Remove the drain line from the control valve. Remove the control valve by rotating the valve head assembly to the left or counter-clockwise and set
aside to reassemble after media is loaded into the tank.
4)
Insert fl exible tubing down the distributor tube and siphon the water from the media tank to aid in adding or replacing fi lter media. Remove fl exible
tubing. Cover the distributor tube with centering tool to prevent media from entering the distributor tube. Add the media you are using to the line on
the side of the media tank. Remove centering tool. Then refi ll the media tank with water utilizing a hose or clean bucket.
Dispose of spent media
in accordance with federal, state, and local regulations
.
5)
Prior to reattaching valve head assembly to the tank, inspect the o-ring for wear. If none, lubricate with silicone grease or water. Reattach valve head
assembly by rotating to the right or clockwise until valve head assembly is seated to the tank hand tight.
6)
Reattach the bypass valve to the control valve and slowly open the bypass. Allow the iron reduction system pressurize and set for the required time
period.
7)
Plug the control valve into the electrical outlet and set the time of day on the display.
8)
Once the saturation time has been achieved, manually initiate an immediate backwash (see Page 4-3). Backwash the media until the water runs clear.
Observe the color of the water in the drain line discharge to determine if is has washed long enough. The water should be fairly clear and absent of
fi nes before quitting the cleaning process. If not, proceed to regenerate the unit again until the water runs clear to the waste drain.
9)
Re-bedding of media tank is now complete.
Draining Water From Filter:
1)
Stage program wheel on control valve powerhead to backwash position to relieve pressure.
IMPORTANT NOTE
IMPORTANT NOTE
Lift end of drain line to retain water in the line. DO NOT allow drain line to empty. If drain connection is to a rigid pipe, disconnect it at the drain
line fl ow control and attach a length of fl exible tubing for this operation.
2)
Stage program wheel to space between backwash and rapid rinse.
3)
Lower end of drain line. Filter will now siphon itself empty of water. You can terminate the siphoning action at any time by staging the control valve
to service position.
