INSTALLATION & STARTUP CONTINUED
Changing Length of Brine Tank Refill Time
The second group of holes on the program wheel determines
the length of time the water conditioner refills the brine tank
(2 minutes per hole).
To change the length of refill time, move the two pins at the
end of the second group of holes as required.
The Regeneration cycle is complete when the two pin set at
end of the brine tank refill section trips the outer
micro-switch. The program wheel, however, continues to
rotate until the inner micro-switch drops into the notch on the
program wheel.
Programming
1. The control valve is set at the factory for backwash; brine
and slow rinse; rapid rinse and brine tank fill times.
Change any of these times by repositioning the pins and
holes or adding more pins.
NOTE: Two timer motors are available.
1/15 RPM has 82 minute Regeneration Time and
each pin or hole equals one minute.
1/30 RPM has 164 minute Regeneration Time and
each pin or hole equals two minutes.
2. The control valve has a separate brine tank fill cycle.
Calculate the desired salt setting using the brine line
flow control rate of refill (in gpm) multiplied by the timer
setting. Then, using one gallon of fresh water dissolving
approximately 3 lbs salt, calculate the refill time.
Example: A desired 30 lbs salt setting:
The unit has a 1.0 gpm refill rate so a 10 gallon fill
is required.
10 gallons x 3 lbs/gals = 30 lbs salt
Set the timer refill section at 10 minutes.
10 minutes x 1.0 gpm = 10 gallon fill
NOTE: There must always be two pins at the end of a refill
time to stop the fill cycle. With the Regeneration
times set, place timer back to its original position,
making sure the lower right hand corner snaps
back into the backplate and the meter cable slides
through the backplate and does not bind.
3. Setting the gallon wheel. Knowing the amount of resin in
each tank and the salt setting per Regeneration, calculate
the gallons available, using the following capacities as a
guide:
(capacity per ft x ft of resin per tank) = gallons available
3 3
compensated hardness of H2O
NOTE: Based on tank size: More resin increases capacity,
less resin decreases capacity.More salt increases
capacity, less salt decreases capacity.

4. Because the control valve regenerates with soft water from
the other tank, subtract the water used for regeneration.
Take each regeneration cycle and calculate the water used.
Example: Unit is set for a 16-inch diameter tank with 4 ft
resin and salted at 8 lbs. per ft
#3 injector, 1.0 gpm brine refill, and 60 psi and
timer set for 10 min. backwash, 60 min. brine and
rinse, 10 min. rapid rinse, 10 min. brine tank fill.

Total Regeneration Water
With the 2740 gallons available calculated in Step 3,
subtract the Regeneration water used from the total
water available.
2740 gallons available - 210 gallons used = 2530
gallons (in Regeneration, Step 4)
5. Set meter wheel at approximately 2530 gallons. Lift the
inner dial of the meter program wheel so that you can
rotate it freely. Position the white dot opposite the
2530 gallon setting.
NOTE: There is a slight delay between the time the meter
zeros out and the cycle starts. Units using the:
1/15 RPM motor, 82 minute Regeneration Time has a
9 minute delay
1/30 RPM motor, 180 minute Regeneration Time has
an 18 minute delay.
NOTE: This delay period is not critical on residential
equipment. However, take this factor into
consideration for commercial applications by
subtracting continuous flows for 9 minutes or 18
minutes from water available.
6. Insert meter cable into meter.
7. Check bypass.
8. Plug in unit.
