Determine whether all equipment connected to the OneFlow
system must be turned off prior to shutting off water supply.

5. Clean inside of housing bowl with warm water. If desired,
disinfect housing bowl using a teaspoon of household
bleach. Add to housing bowl and add water. Let stand
5 minutes and discard.
6. Insert new cartridge into filter housing bowl. Match cartridge
model number to model number on bracket.
7. Make certain the O-ring is properly positioned and reinstall
filter housing (hand tighten only). Check O-ring for damage
and replace if damaged or distorted.
8. Slightly open the inlet ball valve and push the red pressure
relief button to release trapped air in the system. Stop
pressing the pressure relief button when a small amount
of water comes out. Fully open the inlet ball valve.
9. Open the flush valve downline from the filter housing
(if equipped) and flush the new cartridge to drain or bucket
for two (2) minutes or until water runs clear. If no flush valve
is present, disconnect line from equipment to flush to drain.
