RESIN BED CLEANING
If the water supply contains ‘‘clear water ’’iron (see
page 4), regular resin bed cleaning is needed to
keep the bed from coating with iron. Use resin bed
cleaner, available from EcoWater, following direc-
tions on the container. Clean the resin every 6
months, or more often if iron appears in your condi-
tioned water supply.
ADDING RESIN
Normally, the resin bed (FIG. 20) will last the lifetime
of the EcoWater conditioner. However, certain
conditions may require partial or total replacement of
the resin bed. Some of these conditions are:
(1) damaged top and/or bottom distributors have al-
lowed resin to escape
(2) resin bed iron fouled beyond use
(3) some water supplies cause resin degradation

depth,
in the preceding chart, are provided only as
a guide for maintenance when adding to, or if replac-
ing the entire bed with new, fully regenerated, resin
with typical moisture content. Freeboard can vary
several inches depending on resin bed conditions
including...if regenerated or exhausted, total mois-
ture content, settling during shipping and storage,
tolerance variables in resin tank size, and amount
and type of gravel underbedding.
Each model is factory loaded with the specific
pounds or cubic feet of resin required, not by a free-
board measurement. Refer to page 33 for this infor-
mation.
IMPORTANT NOTES:
Turn off the water supply and relieve pressure...see
page 30.
Handle the resin tank carefully. It is heavy when filled
with resin and water.
Do not lose o--ring seals or other small parts.
Refer to the assembly instructions, page 6, and to
installation steps 1, 12, 14, 15 and 18 to reassemble
and restart the unit.
