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

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 6 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 OneFlow

filter cartridges with proven performance, size and operating capacities.

Use of replacement cartridges other than those specified will void war-

ranties, certifications and may compromise equipment protection, water

quality and cartridge life.

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

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

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 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.

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.

11. Record filter change on the service log.
