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.
WARNING:
If opened too rapidly or too far, media may
be lost out of the tank into the valve or the
plumbing. In the 1/4 open position, you should
hear air slowly escaping from the valve
drain line.
B. When all of the air has been purged from the media
tank (water begins to flow steadily from the drain line),
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 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. 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.
NOTE:
We recommend that you do not put regenerant into
the tank until after the control valve has been put into
operation. With no regenerant in the tank, it is much
easier to view water flow and motion in the tank.
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 of the media tank.
B. Advance the controller to the Refill (C8) position. From
cycle C1 (Backwash), press and hold the SET button.
This will display the current cycle.
While pressing the SET button, press UP to advance to
the next cycle. Continue to advance through each cycle
until you have reached cycle C8 (Refill).
NOTE:
As you advance through each cycle there will be a
slight delay before you can advance to the next cycle.
The hourglass icon will light while the camshaft is
indexing. There may be a pause at cycle C4 (System
Pause). This cycle allows the water/air pressure to
equalize on each side of the valve discs before moving
on. The hourglass will not be visible indicating that
the system is paused.

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 button 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.
C. Observe the water being drawn from the regenerant
tank for at least three minutes. If the water level does
not recede, or goes up, check all hose connections. C2
should be displayed.
8. If the water level is receding from the regenerant tank
you can then advance the controller back to the treated
water (C0) position by pressing SET and the UP buttons
simultaneously to advance the controller to the C0 position.
9. Finally, turn on a faucet plumbed after the water
conditioner. Run the faucet until the water runs clear. Add
regenerant to the regenerant tank.
Things You Might Need to Know
• When the controller is first plugged in, it may display a
flashing hourglass and the message Err 3, this means
that the controller is rotating to the home position. If
the Err 2 is displayed, check that the incoming power
frequency matches the controller. The North American
controller will not run with 50 Hz input.
• The preset default time of regeneration is 2:00 AM.
• English or Metric? The World controller senses the
electrical input and decides which is needed. The North
American controller only runs on 60 Hz and defaults to
English units.
• The 700 Series controller can be programmed to
regenerate on specific days of the week.
• If electrical power is not available, the camshaft can be
rotated counterclockwise by hand if the motor is removed.
• The 700 Series controllers send commands to the motor
for camshaft movement. However, water pressure/flow
are required during the regeneration cycle for backwash,
purge and refill, and brine draw to actually take place.
• Make sure control power source is plugged in. The
transformer should be connected to a non-switched
power source.
• You can start programming at the beginning by resetting
the amount of media. When viewing H0 (History Value)
push and hold SET for five seconds. The display reverts
back to --- and any programmed information is lost.
