Cleaning the Injector and Screen
1) Turn off water supply to conditioner:
a) If the conditioner installation has a “three valve” by-pass
system, first open the valve in the bypass line, then close the
valves at the conditioner inlet and outlet.
b) If the conditioner has an integral by-pass valve, put it in the
by-pass position.
c) If there is only a shutoff 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) Remove the two injector cap mounting screws.
5) To replace injector and screen.
a) Pull the screen and injector throat/nozzle assembly out of the
valve body.
b) Insert a new injector throat/nozzle assembly, be sure they are
sealed tightly. Install a new screen.
c) Apply silicone lubricant to new injector cap seal.
6) Replace injector cap with two mounting screws.
7) Tighten screws.
8) Return by-pass or inlet valving to normal service position. Water
pressure should now be applied to the conditioner, and any by-
pass line shutoff.
9) Check for leaks at all seal areas. Check the drain seal with the
control in the backwash position.
10) Plug electrical cord into outlet.
11) Set time of day and cycle the control valve manually to assure
proper function. Make sure control valve is returned to the ser-
vice position.
12) Make sure there is enough salt in the brine tank.
13) Start regeneration cycle manually if water is hard.
