Note on Air Draw Cycle (4): Nitro Filter Only (7) Nitro Pro Only
The longer the unit is set to remain in the Air Draw cycle (4), the more air is drawn into the system. A
default setting of 12 minutes draws air down to the level of a normal media bed height and then returns
the unit to the home display. If the system needs more air, increase the time setting for step (4) or
decrease the number of days between air draw cycles. There is no way to view the number of days
until the next air draw will take place.

is 399. Example: 32,000 grain capacity ( c 032 ).
