1. Manually index the softener control into the service position
and let water ow into the resin tank. When the water ow
stops, open a softened water tap until all air is released
from the lines, then close the tap.
Note: The various regeneration positions may be
2. Manually index the control to the backwash position and
allow water to ow at the drain for 3 or 4 minutes.
3. Remove back cover plate.
4. Make sure that the salt dosage is set as recommended by
the manufacturer. Manually index the control to the brine ll
position and allow the brine tank to ll to the top of the air
check.
5. Manually index the control to the brine draw position and
allow the control to draw water from the brine tank until it
stops.
6. Plug in the electrical cord and look in the sight hole in the
back of the motor to see that it is running. Set the days that
regeneration is to occur by sliding tabs on skipper wheel
outward to expose trip ngers. Each tab is one day. Finger
at red pointer is tonight. Moving clockwise from red pointer,
extend or retract ngers to obtain the desired regeneration
schedule.
7. Manually advance the control to the beginning of the brine
ll position; and allow the control to return to the service
position automatically.
8. Fill the brine tank with salt.
9. Replace back cover on the control.
10. Make sure that any bypass valving is left in the normal
service position.

WATER CONDITIONER FLOW
DIAGRAMS
1 Service Position
Hard water enters the unit at the valve inlet - ows around the
lower piston groove - thru the passage to the top of tank - down
thru the resin and enters the distributor as conditioned water.
The conditioned water ows up thru the center tube to the
valve outlet.
2 Preliminary Rinse Position (5 Minutes)
3 Backwash Position (10 Minutes)
Hard water enters the unit at the valve inlet - ows around
the lower piston groove and lower piston land - down thru the
center tube and out the distributor - up thru the resin - thru the
top of tank passage - around the upper piston groove and out
the drain line.
4 Brine Position (First Portion of 50 Minute Fixed Cycle)
Hard water enters the unit at the valve inlet - ows around
the lower piston groove - down thru the top of tank passage
- downward thru the resin - up the distributor tube - thru the
center hole in the piston - over the top edge of the piston and
out the drain line.
Hard water enters the unit at the valve inlet - ows around the
lower piston groove - thru the injector nozzle and orice to
draw brine from the brine tank. The brine ows down thru the
resin - into the distributor - up thru the center tube - thru the
center hole in the piston and out the drain line.

5 Slow Rinse Position
(Last Portion of 50 Minute Fixed Cycle)
After all the brine has been drawn from the brine tank, hard
water continues to enter thru the valve inlet - ows around the
lower piston groove - thru the nozzle and orice - down thru the
resin and into the distributor - up thru the center tube - thru the
center hole in the piston and out the drain line.
6 Second Backwash Position (10 Minutes)
7 Settling Rinse Position (5 Minutes)
Hard water enters the unit at the valve inlet - ows around
the lower piston groove - down thru the top of tank passage
- downward thru the resin - up the distributor tube - thru the
center hole in the piston - over the top edge of the piston and
out the drain line.
8 Brine Tank Fill Position
(4 to 24 Minutes Adjustable Cycle)
Hard water enters the unit at the valve inlet - ows around
the lower piston groove and lower piston land - down thru the
center tube and out the distributor - up thru the resin - thru the
top of tank passage - around the upper piston groove and out
the drain line.

SERVICE INSTRUCTIONS
A. TO REMOVE TIME BRINE VALVE, INJECTORS, AND
SCREEN
1. Unplug electrical cord from outlet.
2. Turn off water supply to conditioner:
a. If the conditioner installation has a “three valve”
bypass system, rst open the valve in the bypass
line, then close the valves at the conditioner inlet
and outlet.
b. If the conditioner has an integral bypass valve, put
it in the bypass position.
c. If there is only a shut-off valve near the conditioner
inlet, close it.
3. Relieve water pressure in the conditioner by putting the
control in the backwash position momentarily. Return
the control to the service position.
4. Disconnect brine tube and drain line connections at the
injector body.
5. Remove the two injector body mounting screws. The
injector and brine module can now be removed from
the control valve. Remove and discard valve body
O-rings.
6. To replace brine valve:
a. Pull brine valve from injector body, also remove and
discard O-ring at bottom of brine valve hole.
b. Apply silicone lubricant to new O-ring and reinstall
at bottom of brine valve hole.
c. Apply silicone lubricant to O-ring on new valve
assembly and press into brine valve hole, shoulder
on bushing should be ush with injector body.
7. To replace injectors and screen:
a. Remove injector cap and screen, discard O-ring.
Unscrew injector nozzle and throat from injector
body.
b. Screw in new injector throat and nozzle. Be sure
they are seated tightly. Install a new screen.
c. Apply silicone lubricant to new O-ring and install
around oval extension on injector cap.
8. Apply silicone lubricant to three new O-rings and install
over three bosses on injector body.
9. Insert screws with washers through injector cap and
injector. Place this assembly through hole in timer
housing and into mating holes in the valve body.
Tighten screws. Be sure to reinstall brass spacers with
injector on Model 4600 valve.
10. Reconnect brine tube and drain line.
11. Return bypass or inlet valving to normal service
position. Water pressure should now be applied to the
conditioner, and any bypass line shut off.
12. Check for leaks at all seal areas. Check drain seal with
the control in the backwash position.
13. Plug electrical cord into outlet.
14. Set time of day and cycle the control valve manually to
ensure proper function. Make sure the control valve is
returned to the service position.
15. Make sure there is enough brine in the brine tank.
16. Rotate program wheel counterclockwise until it stops at
regeneration position.
17. Start regeneration cycle manually if water is hard.
B. TO REPLACE TIMER
1. Unplug electrical cord from outlet.
2. Turn off water supply to conditioner:
a. If the conditioner installation has a “three valve”
bypass system, rst open the valve in the bypass
line, then close the valves at the conditioner inlet
and outlet.
b. If the conditioner has an integral bypass valve, put
it in the bypass position.
c. If there is only a shut-off valve near the conditioner
inlet, close it.
3. Relieve water pressure in the conditioner by putting the
control in the backwash position momentarily. Return
the control to the service position.
4. Remove the control valve back cover.
5. Remove screw and washer at drive yoke. Remove
timer mounting screws. The entire timer assembly will
now lift off easily.
6. Put new timer on top of valve. Be sure drive pin on
main gear engages slot in drive yoke (rotate control
knob if necessary).
7. Replace timer mounting screws. Replace screw and
washer at drive yoke.
8. Return bypass or inlet valving to normal service
position. Water pressure should now be applied to the
conditioner, and any bypass line shut off.
9. Plug electrical cord into outlet.
10. Set time of day, program wheel, and salt usage. Cycle
the control valve manually to ensure proper function.
Make sure the control valve is returned to the service
position.
11. Replace the control valve back cover. Be sure
grommet at cable hole is in place.
12. Make sure there is enough brine in the brine tank.
13. Rotate program wheel counterclockwise until it stops at
regeneration position.
14. Start regeneration cycle manually if water is hard.
