B. KEEPING THE WATER SOFTENER CLEAN
NOZZLE & VENTURI
A clean nozzle and venturi (FIG. 11) is a must for the
softener to work right. This small unit moves brine
from the salt storage tank to the resin tank during re-
generation. If it becomes plugged with sand, silt,
dirt, etc., the softener will not work and you will get
hard water.
To get to the nozzle and venturi, remove the softener
top cover. Be sure the softener is in service cycle (no
water pressure at nozzle and venturi), then unscrew
the cap from the nozzle and venturi housing. Do not
lose the large o-ring seal. Lift out the screen support
and screen, then the nozzle and venturi. Also check
and clean the gasket, flow plugs and screens. Wash
and rinse the parts in warm water until clean. If
needed, use a small brush to remove iron or dirt.
Carefully replace all parts in the correct order. Lu-
bricate the o-ring seal with silicone grease or Vase-
line and place in position. Install and tighten the
cap, by hand only. Do not overtighten and break
the cap or housing.

IRON FROM RESIN BED
Your water softener takes hardness minerals (cal-
cium and magnesium) out of the water. Also, it can
control some "clear water" iron. See maximum al-
lowed in the specifications on page 4-1. With clear
water iron, water from a faucet is clear when first
put into a glass. After 15 to 30 minutes, the water be-
gins to cloud or turn rust colored. A water softener
WILL NOT remove any iron which makes the water
cloudy or rusty as it comes from the faucet (called
red water iron). To take red water iron out of water,
or over the maximum of clear water iron, an iron _-
ter or other equipment is needed. Your local Sears
store has trained people to help you with iron water
problems.
If your water supply has clear water iron, even
though less than the maximum allowed, regular
resin bed cleaning is needed. Sears has Water Soft-
ener Cleaner, Item No. 42-34426 for this. Clean the
bed at least every 6 months. If iron shows up in the
soft water before 6 months, clean more often.
Printed instructions are on the bottle.
