*This setting requires the use of “XS” (extra salt) cam and doubles the amount of the 
setting.
The amount of salt placed in the brine tank has nothing to do with the amount of salt 
used during the regeneration cycle. Water will dissolve and absorb salt only until it 
becomes saturated. A given amount of brine (salt-saturated water) contains a specific 
amount of salt. The salt dial controls the amount of brine used during the 
regeneration cycle (e.g., when set at 15 pounds (6.8 kg) the amount of brine the 
conditioner will use for each regeneration will contain 15 pounds (6.8 kg) of salt, etc.)
Never let the amount of salt in the brine tank be lower than the normal liquid level. Do 
not overload the brine tank with salt.
Guest Cycle (Manual Regeneration)
When abnormally high water usage exhausts your water conditioner’s capacity 
ahead of schedule, an extra regeneration can be achieved. Depress the indicator knob 
on the 440i (Figure 11) with a wide-blade screwdriver and turn COUNTERCLOCKWISE 
to START to initiate a regeneration. For the 460i, simply depress the indicator knob 
(Figure 12). It will take a few minutes for regeneration to start. A normal regeneration 
will take approximately two hours.
