* JOB NO.

1. Place the softener tank where you want to install the unit making sure the unit is level and on a firm base.

(Maximum 4 feet apart for twin units.)

2. All plumbing should be done in accordance with Iocal plumbing codes. The pipe size for the drain Iine

should be the same size as the drain Iine flow control female connection. Water meters are to be installed

on soft water outlets. Twin units with (1) one meter shall be installed on common soft water outlet of units.

3. Solder joints near the drain must be done prior to connecting the Drain Line Flow Control fitting. Leave at

Ieast 6“ between the DLFC and solder joints when soldering when the pipes are connected on the DLFC.

Failure to do this could cause interior damage to the DLFC.

4. Teflon tape is the only sealant to be used on the drain fitting. The drain from twin units may be run

through a common Iine.

5. Make sure that the floor is clean beneath the salt storage tank and that it is Ievel.

6. Place approximately 1”of water above the grid plate (if used) in your salt tank. Salt may be pIaced in the

unit at this time.

7. On units with a by-pass, place in by-pass position. Turn on the main water supply. Open a cold soft water

tap nearby and Iet run a few minutes or until the system is free from foreign material (usually solder) that

may have resulted from the installation.

8. Place the by-pass in service position.

9. Manually index the softener control into “service” position and Iet water flow into the mineral tank. When

water flow stops, open a cold water tap nearby and Iet run until air pressure is reIieved.

10.Electrical: AII electrical connections must be connected according to codes. Use electrical conduit if

applicable.

11. Plug into power supply.

Commercial Demand Regeneration Control Timer Settings MODEL F50 ECONOMINDERTM

Typical Programming ProcedureCalculate the gallon capacity of the system, subtractthe necessary reserve requirement and set the gallonsrequired by Iifting the gallon dial and rotating it so thatthe number of gallons required is aligned with thewhite dot on program wheel gear. Release and checkfor firm engagement with gear.Note, drawing shows 8,750 gallon setting. The capac-ity (gallons) arrow denotes remaining gallons exclusiveof fixed reserve.

To set Meter capacity at initial start-up either 1. Rotate manual regeneration knob one full revolution. —or— 2. Rotate program wheel manually clockwise or counter clockwise and align white dot with capacity arrow. This procedure must be followed any time the program wheel setting is changed.

Note:

These timers do not have a 24 hour gear. Setting thegallons on the program wheel and manual regenera-tion procedure are the same as previous instructions.

lmmediate Regeneration Timers:

5. In any event, conditioned water may be drawn after rinse water stops flowing from the water conditioner drain Iine.

How To Set The Time Of Day: 1. Press and hold the red button in to is engage the 24 hour gear. 2. Turn the 24 hour gear until the actual time of day is at the time of day pointer 3. Release the red button to again engage the 24 hour gear.

How To Manually Regenerate Your Water Condi-tioner At Any Time: 1. Turn the manual regeneration knob cIockwise one “click.” 2. This slight movement of the manual regeneration knob engages the program wheel and starts the generation program. 3. The black center knob will make one revolution in the folIowing approximately three hours and stop in the position shown in the drawing. 4. Even though it takes three hours for this center knob to complete one revoIution, the regenera tion cycle of your unit might be set for only one half of this time.

How To Set Days On Which Water Conditioner Is ToRegenerate:

How To Set The Time Of Day:

How To Manually Regenerate Your WaterConditioner At Any Time:

How to Adjust Regeneration Time:1. Disconnect the power source.2. Locate the three screws behind the manual regeneration knob by pushing the red button in and rotating the 24 hour dial until each screw appears in the cut out portion of the manual regeneration knob.3. Loosen each screw slightly to release the pressure on the time plate from the 24 hour gear.4. Locate the regeneration time pointer on the inside of the 24 hour dial in the cut out.5. Turn the time plate so the desired regeneration time aligns next to the raised arrow.6. Push the red button in and rotate the 24 hour dial. Tighten each of the three screws.7. Push the red button and Iocate the pointer one more time to ensure the desired regeneration time is correct.8. Reset the time of day and restore power to the unit.

Rotate the skipper wheel until the number “1” is at the redpointer. Set the days that regeneration is to occur by slidingtabs on the skipper wheel outward to expose trip fingers.Each tab is one day. Finger at red pointer is tonight. Movingclockwise from the red pointer, extend or retract fingers toobtain the desired regeneration schedule.

Press and hold the red button in to disengage the drive gear.Turn the Iarge gear until the actual time of day is at the timeof day pointer.Release the red button to again engage the drive gear.

Turn the manual regeneration knob clockwise.This slight movement of the manual regeneration knobengages the program wheel and starts the regenerationprogram.The black center knob will make one revolutionin the following approximatelythree hours and stop in the position shown in the drawing.Even thought it takes three hours for this center knob tocomplete one revolution, the regeneration cycle of yourunit might be set only one half of this time.ln any event,conditioned water may be drawn after rinsewater stopsflowing from the water conditioner drain Iine.

PROBLEM CAUSE CORRECTION

Page 21: MODEL F50 Downflow

Problem: Softener Delivers Hard Water.

Cause couId be that . . . Reserve Capacity Has Been Exceeded.

Correction: Check salt dosage requirements and reset program wheel to provide additional reserve.

Cause could be that . . . Program Wheel Is Not Rotating With Meter Output.

Correction: Pull cable out of meter cover and rotate manually. Program wheel must move without binding and

clutch must give positive “clicks” when program wheel strikes regeneration stop. lf it does not, repIace timer.

Cause could be that . . . Meter Is Not Measuring Flow.

Correction: Check meter with meter checker.
