4. Fill the media tank with water.
A. While the controller is in cycle C1 (backwash), open the water supply valve very slowly to
approximately the 1/4 open position.
B. When all of the air has been purged from the media tank (water begins to flow steadily from
the drainline), open the main supply valve all of the way. This will purge the final air from the tank.
C. Allow water to run to drain until the water runs clear from the drain line. This purges any
refuse from the media bed.
D. Turn off the water supply and let the system stand for about five minutes. This will allow for
any air trapped to escape from the tank.
5. Add water to the regenerant tank (initial fill) - Conditioner only .
A. With a bucket or hose, add approximately 4 gallons (15 liters) of water to the regenerant tank.
B. If the tank has a salt platform in the bottom of the tank, add water until the water level is
approximately 1 inch (25 mm) above the platform.
6. Engage the refill cycle to prime the line between the regenerant tank and the valve
Conditioner only .
A. Slowly open the main water supply valve again, to the fully open position. Be sure not to open
too rapidly as that would push the media out the media tank.
B. Advance the controller to the refill position. From cycle C1 (backwash), press and hold the SET
button. This will display the current cycle.
While pressing the SET button, press the UP arrow to advance to the next cycle. Continue
to advance through each cycle until you have reached cycle C8 (refill).
C. With the water supply completely open, when you arrive at
cycle C8 (refill), the controller will direct water down through
the line to the regenerant tank. Let the water flow through the
line until all air bubbles have been purged from the line.
D. Do not let the water flow down the line to the tank for more
than one to two minutes, or the tank may overfill.
E. Once the air is purged from the line, press the SET button and
the UP button simultaneously to advance to cycle C0 (treated
water) position.
7. Draw water from the regenerant tank.
A. From the treated water position (cycle C0), advance the valve to the draw regenerant
position. Hold the REGEN button down for five seconds.
The controller will begin a manual regen, and advance the control valve to the cycle C1
(backwash). Press the SET and UP buttons to advance to cycle C2 (draw).
B. With the controller in this position, check to see that the water in the regenerant tank is being
drawn out of the tank. The water level in the tank should recede very slowly.
