Replacement cartridges

OneFlow systems can only be used with OneFlow
®
cartridges. Use of replacement cartridges other than those
specified will void warranties, certifications and may compromise
equipment protection, water quality and equipment life.
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. For OneFlow
®
O-ring; for models starting in 2021: use the BLUE O-ring.
Using your fingers (not cloth or paper), spread a small dot
lubricant on the O-ring, just enough to moisten it all the way
around and making sure that the entire O-ring surface is
completely coated with grease. As you work the grease into
the O-ring, make sure there is no grit or debris on the O-ring.
Place the O-ring back on the OneFlow
it is fully seated and level in the groove. Make sure the O-ring
is not pinched or twisted and that no dirt, lint, hair, or any
debris is trapped on the O-ring. This is necessary to maintain a
waterproof seal. Make certain the O-ring is properly positioned
and reinstall 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.
