NOTE: If 25 (factory default) and HARDNESS do not show in the display, press the SET button until they do.
1.
Press either the SET, UP or DOWN button to set
your water hardness number in the display. The
DOWN button moves the display down to 1. The
UP button moves the display up to 95,110, or 120,
depending on the model code.
NOTE: Each press of the UP or DOWN button
changes the display by 1 between 1 and 25. Above
25, the display changes 5 at a time; 25, 30, 35, etc.
Holding a button in changes the numbers twice
each second.
2.
When your water hardness number shows,
press SET to apply.
The special features of your timer are explained on pages 18, 19 and 20.
TO COMPLETE THE INSTALLATION, DO THE SANITIZING BELOW.
Care is taken at the factory to keep your water soft-
ener clean and sanitary. Materials used to make the
softener will not infect or contaminate your water
supply, and will not cause bacteria to form or grow.
However, during shipping, storage, installing and
operating, bacteria could get into the softener. For
this reason, sanitizing as follows is suggestedw
when installing.
1.
Be sure to complete all installation steps, includ-
ing timer programming.
2.
Pour about 3/4 oz of common 5.25% household
bleach (Clorox, Linco, Bo Peep, White Sail, Eagle,
etc.,) into the brinewell (Figure 4, page 10).
NOTE: When the above sanitizing regeneration is over, all remaining bleach is flushed from
the conditioner and your house COLD water supply is fully soft immediately. However, your
water heater is filled with hard water and, as hot water is used, it will refill with soft water.
When all the hard water is replaced, in the water heater, hot only, and mixed hot and cold water
will be fully soft. If you want totally soft water immediately, after the above regeneration, drain
the water heater until the water runs cold. If you do drain the water heater, use extreme care
as the hot water could cause severe burns.

You can get the grains per gal-
lon (gpg) hardness of your wa-
ter supply from a water analysis
laboratory, or call and ask your
local water department, if you
are on a municipal supply.
If your water supply contains
ferrous (clear water) iron, in-
crease the hardness setting to
compensate for it as follows:
Add 5 to the hardness number
for each 1 ppm of iron.

SANITIZING PROCEDURES

3.
Start a recharge: Press the RECHARGE button
and hold for 3 seconds, until RECHARGE NOW
begins to flash in the display. This recharge draws
the sanitizing bleach into and through the water
softener to sanitize it. Any air remaining in the unit
is purged to the drain.
4.
After the recharge has completed, fully open a
cold water faucet, downstream from the softener,
and allow 50 gallons of water to pass through the
system. This should take at least 20 minutes. Close
the faucet.
NOTE: Sanitizing is recommended by the Water Quality Asso-
w
ciation for disinfecting. On some water supplies, they suggest
periodic sanitizing.
