1. Set the time of day in the time of day window. Time of re-
generation is pre-set for 2:00 a.m. If you wish to regenerate
at a different time, you will have to compensate by offsetting
the time of day. Determine time you want regeneration to
take place and figure the time difference between 2:00 a.m.
and actual regeneration time. If regeneration is to take place
earlier than 2:00 a.m., set the time of day for the actual
time plus the difference figured above (set time ahead). If
regeneration is to take place later than 2:00 a.m., set time
of day for the actual time minus the difference figured above
(set time behind). Instructions for setting the time of day
are printed in the bottom left hand corner on the face of the
timer.
2A. WaterMate-1 Series Timer: To set days that regeneration
is to occur, slide tabs on skipper wheel outward to expose
the trip fingers (Figure 10). Each tab is one day. Tab at red
pointer is tonight. Moving clockwise from the red pointer,
extend or retract fingers on the skipper wheel to obtain
desired regeneration schedule. Regeneration may be once
every 12 days, every 6 days, every 4 days, every 3 days,
every 2 days, or everyday.
2B. Regeneration Interval: To choose the proper regeneration
interval, first determine the total grains of hardness to be
removed daily. The average family uses 70 gallons per
person daily for all water uses in the home, about 50 gal-
lons per person daily if hard water can be supplied to the
toilets and about 30 gallons per person daily for hot water
softened only.
Let us assume that we have a family of three persons,
the water is 20 grains hard, and all water is to be softened.
Let us also keep in mind that we would like to have a 3 to
4 day regeneration interval to conserve water.
3 persons x 70 gallons per day x 20 grains per gal-
lon of hardness x 4 days = 16,800 grains minimum
softener capacity.
Check the label on the back of your timer cover for your
salt setting. Go to the capacity rating chart on page 2 and
find your model number and see what your capacity is in
relation to the salt setting. If you need to adjust it, remove
the valve cover and set the salt dial accordingly (Figure
11).
NOTE: Add three (3) grains of hardness per each ppm of iron
present when programming for regeneration frequency.
Example: 20 grains and 1 ppm of iron would be con-
sidered as 23 grains hard (compensated hardness).
3A. WaterMate-1 Timer: Residential Applications - To set the
program wheel, simply lift the “people dial” and rotate so
that the number of people in the household is aligned with
the grains per gallon on the water hardness scale (Figure
12). Release the dial and check for firm engagement at
setting. Add three (3) grains of hardness per ppm of iron
present. Example: 20 grains and 1 ppm of iron would be
considered 23 grains hard (compensated hardness). Salt
setting is preset at factory on all Demand Regeneration
Timer units.
3B. Commercial Applications – Calculate the gallon capacity of
the system, subtract the necessary reserve requirements
and set the gallons available opposite the small white dot
on the program wheel gear. Add three (3) grains of hardness
per ppm of iron present.
