TROUBLESHOOTING
Water leaks at fittings:
Slowly tighten until leak stops.
Water leaks at Push-In connections:
Push tube in as far as it will go. If leaking
continues, turn off water and remove
water line by pushing in on connector
collar while pulling the tube away.
(See Using Push-In Fittings.) Inspect tube.
If tube is cracked or scratched, cut off
damaged end as straight as possible and
reinsert new tube end into fitting.
CLEANING:
The exterior of your filtration system
can be cleaned with warm, soapy water.
Rinse well with fresh, clean water. Never
use chemical cleaning products on the
system’s exterior surface as they may
damage the housing.
FILTER REPLACEMENT
We recommend replacing the AO-MF-B-R
filter every 6 months and earlier if there
is a significant drop in water pressure.
Do not use with water that is microbiologically
unsafe or of unknown water quality without
adequate disinfection before or after the
system. Systems certified for cyst reduction
may be used on disinfected waters that may
contain filterable cysts.
