Service Instructions
A. General Preliminary Instructions – PERFORM BEFORE ALL SERVICING OPERATIONS!
1. Turn off water supply to conditioner.
 If the conditioner installation has a “three valve” bypass system, first open the valve in the bypass line, then
close the valves at the conditioner inlet and outlet.
 If the conditioner has an integral bypass valve, put it in the bypass position.
 If there is only a shut off valve near the conditioner inlet, close it.
2. Relieve water pressure in the conditioner by stepping the control into the backwash position momentarily. Return
the control to the service position.
3. Unplug electrical cord from outlet.
4. Disconnect brine tube and drain line connections at the injector body.
B. To Replace Brine Valve (need first A1-A3)
1. Remove the control valve back cover. Disconnect
the meter signal wire from the meter.
2. Remove screw and washer at drive yoke. Remove
powerhead mounting screws. The entire
powerhead assembly will now lift off easily.
3. Remove piston retaining plate screws and pull
upward on end of piston yoke until assembly is out
of valve.
4. Pull brine valve from injector body, also remove
and discard O ring at bottom of brine valve hole.
5. Apply silicone lubricant to O ring and reinstall at
bottom of brine valve hole.
6. Apply silicone lubricant to O ring on new brine
valve assembly and press into brine valve hole,
shoulder on bushing should be flush with injector
body.
7. Insert screws through injector cap and into mating
holes in the valve body. Tighten screws.
8. Reconnect brine tube and drain line.
9. Return bypass or inlet valving to normal service
position. Water pressure should now be applied to
the conditioner, and any bypass line shut off.
10. Check for leaks at all seal areas. Check drain seal
with the control in the backwash position.
11. Plug electrical cord into outlet.
12. Set time of day and cycle control valve manually to
assure proper function. Make sure control valve is
returned to the service position.
13. Make sure there is enough salt in the brine tank.
14. Start regeneration cycle manually if water is hard.
C. To Replace Injectors & Screen (need first A1 & A3)
1. Remove injector cap screws, remove cap and
discard gasket. Remove vortex generator from end
of the injector assembly.
2. Remove injector assembly. Apply silicone lubricant
to new injector assembly O rings and install. Be
sure to push injector assembly tightly so O rings
are seated. Replace vortex generator. Install a new
screen.
3. Apply silicone lubricant to new gasket and install
around oval extension on injector cap.
4. Repeat B7-B14.
D. To Replace Powerhead
1. Remove the control valve back cover. Remove the
three screws along the outer edge of the back plate
and remove the front cover. Disconnect the power
supply and the circuit board signal wire from the
motor and feed them back through the control.
Disconnect the optical sensor signal wire.
Disconnect the meter signal wire from circuit board
and feed back through the control.
2. Remove screw and washer at drive yoke. Remove
powerhead mounting screws. The entire
powerhead assembly will now lift off easily.
3. Put new powerhead on top of the valve. Be sure
the drive pin on main gear engages slot in drive
yoke (wide side of drive yoke upright must face to
the left away from the motor).
4. Replace powerhead mounting screws. Replace
screw and washer at drive yoke.
5. Reconnect meter signal, optical sensor, power
supply, and circuit board signal wires.
6. Reinstall front cover and back cover.
