Filter Cartridge Replacement Procedure

water supply from filters.
2. Turn OFF water to OneFlow
Inlet Ball Valve.
3. Press the red button to release pressure.
4. Remove housing – use filter wrench if necessary.
5. Remove filter from housing. Clean inside of housing with
warm water. If desired, disinfect housing by adding a
teaspoon of household bleach to housing, fill with water, let
stand for 5 minutes, and then discard.
6. Insert new cartridge into filter housing. Match cartridge
model number to model number on bracket.

distorted. Make certain the O-ring is properly positioned and
reinstall filter housing (hand tighten only).
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.
10. VERY IMPORTANT: With water supply inlet valve OPEN and
water flow confirmed, turn on connected equipment. Failure
to supply water to equipment may cause serious damage.
