can be variable, it is possible that the maintenance
cycle could be more or less than the projected duration.
BayFilter systems in volume -based applications
are designed to treat the WOv in 24 hours initially.
Late in the operaflonal cycle of the BayFiter, the
flow rate will diminish as a resuh of occlusion.ifflu
When the drain down exceeds the regulated
standard, maintenance should be performed.
When a BayFiher system Is first Installed, it is
recommended that it be inspected every six (6)
months. When the filter system exhibits flows below
design levels the system should be maintained. Filter
Cartridge replacement should also be Considered
when sediment levels are at or above the level of
the manifold system. Please contact the BaySaver
