Filter Cartridge Replacement Procedure
IMPORTANT: Determine whether all equipment connected to the Scaleless System must be
turned off prior to shutting off water supply from filters.
1. If required, turn off equipment.
2. Turn OFF water to Scaleless 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 in a filter bowl of water. Let stand 5 minutes, and then
discard.
6. Insert new cartridges into filter housings. Match cartridge model numbers to model num-
bers on bracket or housing.
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 car-
tridges 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.
