Finally, rotate the indicator knob c

ounter-

clockwise 

until the indicator points to

REGENERATION COMPLETE. 

Run water from

a nearby cold-water faucet until the water is clear
and soft.

Adjustment of Timer

1. 

Set days of regeneration (Figure 8).

 

Pull all day pins outward (away from control)

 

Depress day pin(s) at day(s) for which
regeneration is desired.

Note: 

The NEXT DAY day pin is noted on the timer

face. Depressing this pin will insure regeneration the
next day at approximately 2:00am. Since the calendar
cap progresses clockwise, depressing the day pin
immediately counterclockwise will insure regeneration
the following day at 2:00 am. This progression is
noted on the timer face as "FUTURE DAYS".

2. 

Set the time of day.

 

Rotate Clock Dial until the pointer is directed
at the current time.

Note: 

With the time of day properly set, the

conditioner will regenerate at about 2:00 am. If you
prefer to have the unit regenerate at an earlier or later
time, simply set the current time-of-day accordingly.
(e.g., To have the unit REGENERATE at 4:00am - 2
hours later - set the clock 2 hours later than the actual
time).

Note: 

Do not rotate the Calendar Cap by hand; the

clock dial indexes it daily. To manually index the
Calendar Cap, rotate the Clock Dial clockwise one
complete turn for every day to be indexed.

Special Features of Timer

Guest Cycle. 

When abnormally high water usage

exhausts the water conditioner's capacity ahead of
schedule, an extra regeneration can be achieved by
turning the indicator knob 

counterclockwise 

to

START, 

Figure 8. It will take a few minutes for regen-

eration to begin. The normal regeneration schedule
will not be disrupted.

Manual Regeneration. 

Electricity is used only to run

the timer and to rotate the camshaft. All other
functions are operated by water pressure. Therefore,
in the event of a power outage, all the various
regeneration positions may be dialled manually by
rotating the indicator knob 

counterclockwise

.

Manual time cycle:

BACKWASH……………………..14 minutes
BRINE AND SLOW RINSE……. 52 minutes
FAST RINSE…………………….. 6 minutes
REFILL…………………………… Read  time

                                                       

Off Salt Dial

Adjustment of Brine control

All models may be tuned to produce maximum to
minimum conditioning capacities by adjusting the Salt
Dial (Figure 9). The Salt Dial controls the amount of
salt used per regeneration. When desired, the
minimum setting may be used if the frequency of
regeneration is increased to compensate for the lower
regenerated conditioning capacity.

How to Set the Salt Dial

With the indicator knob in the REGENERATION
COM-PLETE position (Figure 8), rotate the Salt Dial
counter-clockwise at least one full turn to cancel out
the previous setting. A light clicking will be replaced
by a heavier clicking when the previous setting is
cancelled. Then, rotate the Salt Dial to the proper salt
setting.

The numbers on the dial are "minutes" of water flow
to the brine tank. When using the .4 gpm Brine Refill
Control, each minute corresponds to 1.2 pounds of
salt. The size of the brine control is embossed on the
refill cap. The embossed number corresponds to the
gpm flow control. Example: 

33 

corresponds to .33
