Filter Cartridge Replacement Procedure
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® system by closing 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 housings using a teaspoon of household bleach.
Add to filter bowl and fill with water. Let stand 5 minutes and
discard.
6. Insert new cartridges into filter housings. Match cartridge
model numbers to model numbers on bracket.
7. Make certain the O-ring is properly positioned and reinstall
filter housings (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
btton 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 cartridges to drain or to bucket
for two (2) minutes or until water runs clear. If no flush valve
is present, disconnect line from equipment to flush to drain.

Maintenance
Routine maintenance of your OneFlow
®
System involves periodic
filter cartridge changes and/or replacement of sump O-rings. If the
system sizing recommendations have been followed, the OneFlow
®
System will provide a six (6) month filter replacement interval on
most tap water for the OF110RC cartridge. The OneFlow
®
Cartridge
OF110RM should last one (1) year.
Filter Change Frequency
The filters should be changed in response to the following conditions.
OF110RC
• 6 months since installation or last filter change
• Reduced water flow
OF110RM
•
12 months since installation or last filter change
If filter change frequency is less than six months due to pressure
drop, it may be necessary to add additional prefiltration or evalu-
ate system sizing recommendations.
Replacement Filter Cartridges
OneFlow
®
systems are designed, tested, and certified with One-
Flow
®
filter cartridges with proven performance, size and operat-
ing capacities. Use of replacement cartridges other than those
specified will void warranties, certifications and may compromise
equipment protection, water quality and cartridge life.
