General and Commercial Installation Checklist

Water Pressure

A minimum of 25 lbs of water pressure is required for regeneration valve to operate effectively.

Electrical Facilities

An uninterrupted alternating current (A/C) supply is required. Make sure:

• Voltage supply is compatible with unit before installation.

• Current supply is always hot and cannot be turned off with another switch.

Existing Plumbing

Condition of existing plumbing should be free from lime and iron buildup. Replace piping that has heavy lime
and/or iron build-up. If piping is clogged with iron, install a separate iron filter unit ahead of the water softener.

Location of Softener and Drain

Locate the softener close to a clean working drain and connect according to local plumbing codes.

Bypass Valves

Always provide for the installation of a bypass valve if unit is not equipped with one.

Installation Checklist

1. Place the softener tanks where you want to install the unit.

  NOTE:Besurethetanksarelevelandonarmbase.

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-ring seal. Place
the main control valve on one tank and the tank adapter on the
second tank.*

NOTE:Ifrequired,soldercoppertubingfortankintercon-

nection before assembling on the main control valve and

tankadapter.Maintainaminimumof1"distancebetween

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 Teflon

9. Be sure the floor under the salt storage tank is clean, level, and
strong enough to support the system..

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.

11. Place the system in Bypass.

— 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.

12. Place the bypass In Service position and let water flow into the
mineral tank.

Electrical

13. Make all electrical connections according to codes. Plug the
valve into an approved power source. Do not insert meter cable
into the meter yet.

14. Tank one has control valve and tank two has adapter. See Figure
1, page 4.

15. Look on the right side of the control valve, it has indicators
showing which position the control valve is in during Regenera­tion and which tank is In Service.

the micro switch rides on the first set of pins.

— In this position the tank's switch (lower piston) and the control

valve moves to the backwash position (upper piston).

— Wait until the positioning of upper and lower pistons stops

before advancing the timer further. If advanced too fast the
control will not home into the In Service position (it will not
advance to any other position). To correct this, rotate the
manual knob back to In Service and start again into back­wash.

18. Once back in the In Service position, cycle the control valve
again into the backwash position. The tanks switch again, and
air head backwashes out of the other tank. Once the system
reaches the backwash position unplug it again. Allow the system
to remain in the backwash position until all air is purged from the
system. When all air is gone no air will come out of the drain line.
Then plug the unit back in.

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.

Meter cable

must

be removed from meter dome before opening timer.

Changing Length of the Backwash Time

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.

Set the timer refill section at 10 minutes.

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.

10 gallons x 3 lbs/gals = 30 lbs salt

10 minutes x 1.0 gpm = 10 gallon fill

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

4. 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:

5. Insert meter cable into meter.

6. Check bypass.

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
1/30 RPM motor, 180 minute Regeneration Time has an 18

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

Total Regeneration Water = 210.0 gallons
