General and Commercial Installation Checklist
1. Place the softener tank where you want to install the unit.
NOTE:
2. During cold weather it is recommended that the installer warm the valve to room temperature before operating.
3. 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 flow rates that exceed 7 gpm or length that exceeds 20′ (6 m).
4. Both tanks must be the same height and diameter and filled with equal amounts of media.
5. The distributor tube must be flush with the top of each tank. Cut if necessary. Use only non-aerosol silicone lubricant.
6. Lubricate the distributor o-ring seal and tank o adapter on the second tank.
NOTE:
7. Solder joints near the drain must be done before connecting the Drain Line Flow Control fitting (DLFC). Leave at least 6" (152 mm) between the DLFC and solder joints when soldering pipes that are connected on the DLFC. Failure to do this could cause interior damage to DLFC.
8. Use only
9. Be sure the floor under the salt storage tank is clean and level.
10. Place approximately 1" (25 mm) of water above the grid plate. If a grid is not utilized, fill to the top of the air check in the salt tank. Do not add salt to the brine tank at this time.
Be sure the tank is level and on a firm base.

11. 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.
12. Place the bypass In 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.

Regeneration Cycle Program Setting Procedure
Setting the Regeneration Cycle Program
The Regeneration cycle program on the water conditioner is preset at the factory. However, portions of the cycle or program time may be lengthened or shortened for local conditions or system design.
1. Expose cycle program wheel by grasping timer in lower right hand corner and pulling. This releases snap retainer and swings timer to the left
NOTE:
2. Remove the program wheel by grasping program wheel and squeezing protruding lugs towards center. Lift program wheel off timer.
— Switch arms may require movement to facilitate removal.
3. Return timer to closed position by engaging snap retainer in back plate.
— Make certain all electrical wires locate above snap retainer post.
Changing Length of the Backwash Time
Meter cable
must
be removed from meter dome before opening timer.
The program wheel in group of pins starting at zero determines the length of time the unit backwashes.
Example:
— The number of pins multiplied by two equals minutes of backwash.
If there are six pins in this section, the time of backwash is 12 minutes (2 minutes per pin). To change the length of backwash time, add or remove pins as required.
Figure 5
is In Service position. Looking at the numbered side of the program wheel, the
Changing Length of Brine and Rinse Time
The group of holes between the last pin in the backwash section and the second group of pins determines the length of time that a unit will brine and rinse (2 minutes per hole).
To change the length of brine and rinse time, add or remove pins in the rapid rinse group of pins to increase or decrease the number of holes in the brine and rinse section.
— The number of holes multiplied by two equals minutes of brine and rinse.
Changing Length Of Rapid Rinse
The second group of pins on the program wheel determines the length of time the water conditioner rapid rinses (2 minutes per pin). To change the length of rapid rinse time, add or remove pins at the higher numbered end of this section as required.
— The number of pins multiplied by two equals minutes of rapid rinse.
NOTE:
Program wheels with 0–82 minute cycle times, use one minute per pin or hole to set Regeneration times. The layout of pins and holes on the program wheel follow the same procedure as on this page.
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.

Time Brine Refill and Meter Setting Procedure
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:
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
Example:
NOTE:
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:
Two speed 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.
timer setting. Then, using one gallon of fresh water dissolving approximately 3 lbs salt, calculate the refill time.
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
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.

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.
10 minutes x 7.0 gpm = 70.0 gallons 60 minutes x 1.0 gpm = 60.0 gallons 10 minutes x 7.0 gpm = 70.0 gallons 10 minutes x 1.0 gpm = 10.0 gallons

Control Operation During Programming
The control enters Program Mode with the valve In Service. While in Program Mode the control continues to operate normally, monitoring water usage and keeping all displays up to date. Control programming is stored in memory permanently. There is no need for battery backup power.
Control Operation During A Power Failure
During a power failure all control displays and programming are stored for use upon power re-application. The control retains these values for years, if necessary, without loss. The control is fully inoperative and any calls for Regeneration are delayed. The control, upon power re-application, resumes normal operation from the point that it was interrupted. An inaccurate or flashing Time of Day display indicates that a power outage has occurred.
