Replacement cartridges

OneFlow systems can only be used with OneFlow

Cartridge replacement procedure
1. IMPORTANT: All other equipment connected to the OneFlow
system must be turned off prior to shutting off water supply
from filters.
2. Release pressure by turning the black screwable plastic swivel
button identified by the "VENT" sign (H).
3. Turn OFF water to
inlet ball valve.
4. Remove housing – use cartridge wrench if necessary.
5. Remove cartridge 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 the housing. Match cartridge model
number to model number on bracket.
7. Check O-ring (E) for damage and replace if damaged or
distorted. Make certain the O-ring is properly positioned and
reinstall filter housing (hand tighten only).
8. Slightly open the inlet ball valve; open the pressure relief
swivel (H) to release trapped air until a small amount of water
comes out – close the pressure relief button and fully open
the ball valve.
9. 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.
