General Valve Installation Procedure
Note: Install the water softener with the inlet, outlet and drain connections made according to manufacturer’s recommendations and to
meet applicable plumbing codes.
1. Locate the softener tank close to a drain where you wish to install the unit. Note: Be sure the tank is level and on a rm base.
2. Perform all plumbing according to local plumbing codes.
• Use a 1/2" minimum pipe size for the drain.
• Use a 3/4" drain line for backwash ow rates that exceed 7 gpm or length that exceeds 20' (6 m).
3. Cut the 1" distributor tube (1.050 O.D.) ush with top of each tank.
Note: Only use silicone lubricant.
4. Lubricate the distributor O-ring seal and tank O-ring seal. Screw the valve on to the tank.
5. Use only Teon tape on the drain tting. 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 solder joints when soldering pipes that are connected to the valve. Failure to do this
could cause damage to the valve.
6. Be sure the oor under the brine tank is clean and level.
7. Add water until there is approximately 1" (25 mm) of water above the grid plate. If a grid is not utilized, ll to the top of the air check in
the brine tank. Do not add salt to the brine tank at this time.
8. On units with a bypass, place in Bypass position.
•Turn on the main water supply.
•Open a cold soft water tap nearby and let water run a few minutes or until the system is free of foreign material (usually solder)
resulting from the installation. Close the water tap when water runs clean.
9. Place the bypass in the In Service position and let water ow into the mineral tank. When water ow stops, slowly open a cold water
tap nearby and let water run until air is purged from the unit. Then close tap.
10. Plug the valve into an approved power source
Water Pressure Minimum 25 PSI
Electrical Supply Uninterrupted AC. Check voltage compatibility
Existing Free of any deposits or build-ups inside pipes
Softener 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 100°F water temperature

1. Manually index the softener control into the In Service position and let water ow into the resin tank. When the water ow stops,
open a softened water tap until all air is released from the lines. Then close tap.
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.
2. Manually index the control to the Backwash position and allow water to ow at the drain for 3 or 4 minutes.
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 ll to the top of the air check.
5. Manually index the control to the Brine Draw 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. Set the days that regeneration is
to occur by sliding tabs on skipper wheel upward .
•Each tab is one day.
•Finger at red pointer is tonight.
•Moving clockwise from red pointer, pull or push ngers to obtain the desired regeneration schedule.
7. Manually advance the control to the beginning of the Brine Fill position and allow the control to return to the In Service position
automatically.
8. Fill the brine tank with salt.

Before Plugging in the Unit
1. Open a treated water tap down stream of the lter.
2. Manually index the lter to the In Service position and allow the mineral tank to ll by slowly opening the main water supply valve.
Any bypass should be in the In Service position.
Note: The water owing from the downstream tap is cloudy and/or contains media nes as well as air. Allow the water to run until it
appears clean and free of air.
3. When a steady clean ow appears at the tap, close the tap and the main water supply valve and allow the lter media bed to settle for
15–20 minutes.
4. Manually index the lter to the Backwash position.
5. To prevent a sudden surge of water and air, partially open the main water supply valve so that the ow at the drain of the lter is
approximately 1 gpm (3.7 Lpm). The water at the drain is cloudy again and/or contains media nes as well as air. Allow water to ow at
the drain until it appears clean and free of air.
6. Continue to open the water supply valve until it is completely open. Allow water to ow at the drain until all media nes are washed
out of the lter.
7. Manually index the lter to the In Service position, and again open the downstream tap. Check to be sure that the water ows clear.
If necessary, allow water to ow until all media nes are gone. If the tap is equipped with an aerator check that is not plugged with
media nes and pipe scale.
8. Plug in the electrical cord and look in the sight hole in the back of the motor to see that it is running. Set the days that regeneration is
to occur by sliding tabs on skipper wheel upward .
•Each tab is one day.
•Finger at red pointer is tonight.
•Moving clockwise from red pointer, pull or push ngers to obtain the desired regeneration schedule.
9. Set time of day by pushing blue button and spin the 24-hour gear until the present time of day is visible above the time of day arrow

1. Manually index the softener control to the In Service position and let water ow into the resin tank. When the water ow stops, open a
softened water tap until all air is released from the lines. Then close tap.
Note: The various regeneration positions may be dialed manually by turning the knob on the front of the control until the indicator
shows that the softener is in the desired position.
2. Set water usage program wheel :Calculate the gallon capacity of the system by dividing the system capacity by the raw water
hardness. Next subtract the necessary reserve requirement by multiplying the number of people in the house by 75 gallons (1
US gallon=3.785 L) per day. Set the gallons available at the small white dot on program wheel gear. The capacity arrow denotes
remaining gallons exclusive of xed reserve. The table below is also a quick reference to determine the gallons used before each
regeneration.
3. Rotate program wheel counterclockwise until it stops at Regeneration position.
4. Manually index the control to the Backwash position and allow water to ow at the drain for 3 or 4 minutes.
5. Remove back cover plate.
6. Make sure than the salt dosage is set as recommended by the manufacturer. Manually index the control to the Brine Fill position and
allow the brine tank to ll to the top of the air check.

Flow Diagrams
1) Service Position
Hard water enters unit at valve inlet and ows down
through the mineral in the mineral tank. Conditioned water
enters center tube through the bottom distributor, then
ows up through the center tube, around the piston, and
out the outlet of the valve.
2) Preliminary Rinse Position
Slow rinse of the resin bed. Water ows down through the
resin bed, up the bottom distributor and out the drain.

3) Backwash Position
Hard water enters unit at valve inlet, ows through piston,
down center tube, through bottom distributor, up the
through the mineral, around the piston and out the drain
line. Water is passed through the resin bed in the opposite
direction of normal ow, which ushes suspended matter
out of the resin tank. Backwashing also loosens the resin
bed which becomes compacted during the softening (in
service) cycle.
4) Brine Position (Softeners Only)
Hard water enters unit at valve inlet, ows up into injector
housing and down through nozzle and throat to draw brine
from the brine tank, brine ows down through mineral
and enters the center tube through the bottom distributor
and out through the drain line. The resin beads are washed
with the strong solution of salt water which is called the
brine solution. Since the resin beads prefer calcium and
magnesium ions.

5) Slow Rinse Position (Softeners Only)
After all the brine has been drawn from the brine tank,
hard water continues to enter through the valve inlet, ows
around the lower piston groove and through the nozzle
and throat, down through the resin and into the distributor,
then up through the center tube, at last through the center
hole in the piston and out the drain.
6) Rapid Rinse Position (Second Backwash
Position)
The resin bed rinsed to remove excess brine solution from
the tank and the resin beads are the ready to produce
soft water again. Hard water enters unit at valve inlet,
ows through piston, down center tube, through bottom
distributor, and up through the mineral, around the piston
and out the drain line.
