*The suggested Progressive Flow Trip Point is simply a suggested flow rate at which point an additional tank will be
brought on-line if facility flow demands meet this rate. The Culligan MVP Controller will not remove tank brought on-line
by attaining the Trip Point unless the flow is <95% of the Trip Point amount for a 60 second period. In the event additional
units are not brought on-line or off-line when desired, simply adjust the programmed Trip Point. Refer to the system in-
struction manual operation and programming sections for more information about the progressive flow mode of operation.
