Common Features
When using the 255 valve with the 440i or 460i controls, there are several
features and procedures that are unique to the 400 series controls. They are as
follows:
Salt Dial Adjustment
These models may be adjusted to produce maximum to minimum conditioning
capacities by setting the salt dial, which controls the amount of salt used per
regeneration. When desired, the minimum setting may be used on installations if
the frequency of regeneration is increased to compensate for lower regenerated
conditioning capacity. The installing dealer will set the unit for proper salt usage.
Further adjustments are needed only if the hardness of the water supply changes
or if water use changes dramatically. Capacity will need to be adjusted
accordingly.
To adjust salt dosage, insert a small screwdriver into the white indicator knob and
move pointer to proper salt setting (Figure 13).
Note: To convert the salt settings from English to metric, divide by 2.2 (e.g., 12
pounds ÷ 2.2 = 5.5 kg of salt).
