Brine Valve "A" Dimension
The brine valve contains a float-actuated safety shut-off device to prevent overflow of the brine tank in the un
likely case of an electrical or mechanical failure during the brine tank refill cycle.
It is recommended that the brine valve float be used as intended, that is, as a secondary, safety shutoff. Remem-
ber, the timer mechanism provides the primary refill shut-off. To use the float as a safety shut-off, refer to Table 6
for the salt dosage and brine tank size being used. The "A" dimension is the distance between the filter screen and
the bottom of the float (Fig. 12) when the float stem is in its fully raised position; adjust the float and rubber
grommets accordingly.
RAPID RINSE
The rapid rinse time, which is established when setting the salt dosage, is usually adequate for most installations.
It may be increased, if necessary, but it MUST NEVER be reduced from the salt dosage which is required for
adequate regeneration.
To adjust rapid rinse refer to the section on Salt Dosage. Each one-pound increase in salt dosage will increase
rapid rinse time, the brine valve float will become the primary brine refill shutoff. In this case refer to the correct
Table 7 column for the salt dosage and brine tank size being used, and adjust the "A" dimension accordingly.
