gpm flow control. One gallon of water will dissolve 3.0
pounds of salt.
To calculate the time for brine refill, it is necessary to
determine the needed pounds of salt and divide that
number by three (3 pounds per gallon) and also divide
by the flow control gpm. The result is the time setting
in minutes for brine refill. Be sure to round off times to
the nearest minute
Reference Table 1 for common settings.

Removing the Timer Assembly
Complete the following steps to remove the timer
assembly for servicing:
