IMPORTANT
Determine whether all equipment connected to the OneFlow
system must be turned off prior to shutting off water supply from
filters.
1. If required, turn off equipment.
2. Turn OFF water to OneFlow
Inlet Ball Valve.
3. Press the red button to release pressure.
4. Remove housing(s) - use filter wrench if necessary.
5. Clean inside of housing sumps with warm water. If desired,
disinfect housing using a teaspoon of household bleach.
Add to filter bowl and add water. Let stand 5 minutes and
discard.
6. Insert new cartridge into filter housing. 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; push the red pressure relief
button to release trapped air until a small amount of water
comes out - release the red button and fully open the 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.
