Getting Maximum Efficiency From The Appliance - A.O. Smith Pro AOW-S400 Owner's Manual

GETTING MAXIMUM EFFICIENCY FROM THE APPLIANCE

6
To achieve the maximum benefit and performance from your water softener, familiarize
yourself with this manual. If this device is not maintained and operated as specified in the
owner's manual, there is a risk of exposure to contaminants.
• The salt level should always be at least 1/3
full. Refill salt when the level drops below
the water level in the brine cabinet. A
resin cleaner can be used on a monthly
basis. Clean white pellet, cube-style, or
solar salt is recommended.
Do not use rock salt.
NOTICE: Do not mix different types of salt.
• You may use a salt substitute (such
as potassium chloride) in place of
water conditioner salt. If potassium
chloride is used in place of salt, multiply
compensated hardness by 1.12.
NOTICE: Do not use potassium chloride if
there is iron and/or manganese in the water.
• Should your electricity be off for any
reason, check your controller for correct
time and reset as necessary. (see Setting
The Controller on page 14)
• Program the water softener to regenerate
at a time when water is not being
used. If there is more than one water
appliance, allow two hours between each
regeneration.
• If dirt, sand, or large particles are present
in water supply, the self-contained water
softener filter will remove some dirt and
sediment.

• The water softener may be disinfected
with 5.25% sodium hypochlorite, which
is the active ingredient in household
chlorine bleach. To disinfect appliance,
add 4.0 fluid ounces (120 mL) of chlorine
bleach solution to brine well of the brine
tank. Brine tank should have water in it.
You may also add it directly into brine
cabinet if there is no salt and only water in
cabinet. Start a manual regeneration.
WARNING:
TOXIC CHEMICAL REACTION
Do not mix bleach with commercial resin
cleaner since a dangerous chemical reaction
may occur. Inhalation of a toxic chemical
reaction can cause loss of consciousness and
severe burning with physical contact.
• Protect the water softener, including the
drain line, from freezing.
• Bypass Valve (attached to the main
control valve) enables you to bypass
the water softener if any work is being
performed on it, the well pump, or
plumbing. Use Bypass Mode also for
watering plants or lawns with untreated
water. To bypass, turn black knob to the
left until it hits the stop; turn it to the
right to restore service. (see Bypass Valve
Overview)
• Before putting water softener back in
service after work has been performed,
turn on nearest cold water tap until water
runs clear.
• Adhere to all operational, maintenance,
and placement requirements.
• Inspect and clean the brine cabinet and
air check/draw tube assembly annually or
when sediment is present in brine tank.
