Start-upProcedure
1. Turn the knob and index the control into the Backwash position. Place the bypass
in the Service position and let water flow into the mineral tank. Allow water to run
to drain for 3-4 minutes or until all media fines are washed out of the softener or
filter.
NOTE: Manually dial the various regeneration positions by turning the knob on
the front of the control until the indicator shows that the softener is in the desired
position. For backwash filters ignore steps 3 to 5 and 7 to 9.
2. Manually index the control back to the Service position and open a softened water tap
until all air is released from the lines. Then close the tap.
3. Remove back cover plate.
4. Make sure that the salt dosage is set as recommended by the manufacturer. If necessary,
set salt according to the setting instruction sheet. Manually index the control to the Brine
Fill position and allow the brine tank to fill to the top of the air check.
5. Manually index the control to the Brine Fill position and allow the control to draw water
from the brine tank until it stops.
6. Plug in the electrical cord and look in the sight hole in the back of the motor to see that it
is running.
7. To set time of day press red time set button and turn 24-hour gear until present time of
day is at “time of day.”
8. Timer Settings (Filter or Softener)
Set the regeneration days is to occur by sliding tabs on skipper wheel outward to expose
trip fingers.
Each tab is one day.

Finger at red pointer is tonight.
Moving clockwise from red pointer, extend or retract fingers to obtain the desired
regeneration schedule.
The next table can be used to determine the regeneration frequency.
Regeneration Reference Chart
9. Manually advance the control to the beginning of the Brine Fill position and allow the
control to return to the Service position automatically.
10. Fill the brine tank with salt.
11. Place back cover on the control.
12. Make sure that any bypass valve is turned to the Service position.
Refill Volume Adjustment
Refill volume can be adjusted through Refill Regulator (see the following picture). To
adjust Refill volume, release the screw at first, and then turn the Refill Regulator to desired
volume according to the Meter Label of Brine Gear, finally tighten the screw.

Water Hardness Adjustment (Optional for Softener Valve)
Users can adjust the Water Hardness Adjustment Nut to get their required water
hardness (optional for softener valve)
Operation methods:
Rotate the Water Hardness Adjustment Nut in a clockwise direction. The bigger
rotation angle, the higher water hardness.

GeneralValveInstallation
Water Pressure Minimum 25 PSI
Electrical Supply Uninterrupted AC
Existing Plumbing Free of any deposits or built-ups inside pipes
Softener Location Locate close to drain and connect according to
plumbing codes
Bypass Valves Always provide for bypass valve if unit is not
equipped with one
CAUTION
Do not exceed 120 psi water pressure.
Do not exceed 110℉water temperature.
Do not subject unit to freezing conditions.
1. Locate the softener tank and brine tank close to a drain where the system will be installed.
The surface should be clean and level.
2. Perform all plumbing according to local plumbing codes.
Use a 1/2” minimum pipe or tubing size for the drain line.
Use a 3/4” pipe or tubing for backwash flow rates that exceed 7 gpm or length that
exceeds 20ft (6m).
3. Only use Teflon tape on the drain fitting. Any solder joints near the valve must be done before
connecting any piping to the valve. Always leave at least 6” (152 mm) between the valve and
joints when soldering pipes that are connected to the valve. Failure to do this could cause
damage to the valve.
4. Cut the 1” central pipe flush with top of each tank.
5. Lubricate the o-ring on the bottom of valve that seals against the tank. Screw the valve on to
the tank. Be careful to not cross thread the valve into the tank. Only use silicone lubricant.
6. Add water until there is approximately 1” (25mm) of water above the grid plate. If the tank
does not have a grid, add water until it is above the air check in the brine tank. Do not add salt
to the brine tank at this time.
7. If the unit has a bypass valve, place it in the bypass position.
8. Slowly turn on the main water supply.
9. Open a cold soft water tap nearby and let water run a few minutes or until the system is free
of foreign material resulting from the plumbing work. Close the water tap when water runs
clean.
10. Place the bypass in the service position and let water flow into the mineral tank. When water
flow stops, slowly open a cold water tap nearby and let water run until air is purged from the
unit. Then close tap.

TroubleShooting
Issue Possible Cause Possible Solution
1. No power supply. Check electrical service, fuse, etc.A. Unit fails to initiate a
regeneration cycle. 2. Power failure Reset time of day.
1. By-pass valve open. Close by-pass valve.
2. Out of salt. Add salt to tank.
3. Plugged injector / screen Clean parts.
4. Flow of water blocked to brine tank. Check brine tank refill rate.
5. Hard water in hot water tank. Repeat flushing of hot water tank
required.
6. Leak between valve and central
tube.
Check if central tube is cracked or o-ring
is damaged. Replace faulty parts.
B. Water is hard.
7. Internal valve leak. Replace valve seals, spacer, and piston
assembly.
C. Salt usage is high. 1. Refill time is too high. Check refill time setting.
1. Iron or scale builds up in line feeding
unit.
Clean pipes.
2. Iron build up inside valve or tank. Clean control and add resin cleaner to
clean bed. Increase regeneration
frequency.
D. Low water pressure.
3. Inlet of control plugged due to
foreign material.
Remove piston and clean control valve.
1. Air in water system. Check well system for proper air
eliminator control.
E. Resin in drain line.
2. Incorrect drain line flow control
(DLFC) button.
Check for proper flow rate.
1. Plugged injector or screen. Clean parts.F. Too much water in brine
tank. 2. Foreign material in brine tank. Clean parts.
1. Drain line flow control is plugged. Clean parts.
2. Injector or screen is plugged. Clean parts.
3. Inlet pressure too low. Increase pressure to 25 PSI.
G. Unit fails to draw brine.
4. Internal valve leak. Replace seals, spacers, and piston
assembly
H. Valve continuously cycles. 1. Broken gear. Replace faulty parts.
1. Valve settings incorrect. Check valve settings.
2. Foreign material in control valve. Clean control valve.
I. Flow to drain continuously.
3. Internal leak. Replace seals, spacers, and piston
assembly.
