SECTION 3 CARE OF YOUR FILTER
C. CLEANING THE FILTER RESIN BED
To keep the tannin resin bed clean and working
efficiently, do the following at least once each
month.
Use one gallon of luke warm water (do not use hot
water) to fully dissolve 1 cup of soda ash. After
thoroughly stirred, pour the solution directly into
the brinewell (see key no. 25, page 6-2).
The solution will be drawn into and through the
resin bed during filter regenerations.
D. CLEANING THE NOZZLE AND VENTURI
A clean nozzle and venturi (Figure 12) is a must
for the filter to work right. This small unit moves
brine from the salt storage tank to the resin tank
during regeneration. If it becomes plugged with
sand, silt, dirt, etc., the filter will not work and
you will get unfiltered water.
Be sure the filter is in service cycle (no water pres­
sure at nozzle and venturi), then turn off the cap
from the nozzle and venturi housing. Lift out the
screen support and screen, then the nozzle and
venturi. Wash and rinse the parts in warm water
until clean. If needed use a small brush to remove
iron or dirt. Also check and clean the gasket and
flow plug if dirty.
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 OVER TIGHTEN
AND BREAK THE CAP OR HOUSING.
It is recommended that you clean the nozzle and
venturi at least three times a year. Clean more
often if you notice a difference in water quality.
