Operation
With sufficient pressure, operation of the OneFlow
is completely automatic. Dependable operation involves only
monitoring of outlet pressure, periodic filter changes and service
documentation.
Maintenance
Routine maintenance of your OneFlow
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 OF140RC cartridge. The One-
Flow
Cartridge OF140RM should last one year.

Filter Change Frequency
The filters should be changed in response to the following conditions.
OF140RC
• 6 months since installation or last filter change.
• Reduced water flow.
OF140RM
• 12 months since installation or last filter change.
If filter change frequency is less than 6 months due to pressure
drop, it may be necessary to add additional prefiltration or evaluate
system sizing recommendations.
Filter Cartridge Replacement Procedure
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
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 then 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 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 cartridges 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.
NOTICE
10. With water supply inlet valve OPEN and water flow con-
firmed, turn on connected equipment. Failure to supply
water to equipment may cause serious damage.
11. Record filter change on the service log.
