Operation
With adequate pressure, normal operation of the ASXlOO System is completely automatic. Dependable operation
involves only monitoring of outlet pressure, periodic filter changes and service documentation.
Maintenance
The only routine maintenance your ASXlOO System should ever require is periodic filter cartridge changes or replace­
ment sump O-rings. Filter changes are necessary for optimum performance of your foodservice equipment. If the
system sizing recommendations have been followed the ASXlOO System is designed to provide a twelve (12) month
filter replacement interval on most tap water.
Filter Change Frequency
Several sihiations will mandate filter changes. Complete filter sets should be changed when any of the following ap­
ply:
• Twelve (12) Months have passed since unit installation or previous filter change.
• Reduced water flow.
If filter change frequency is less than 12 months due to pressure drop, it may be necessary to add additional prefiltra­
tion or evaluate system sizing recommendations.
Filter Cartridge Replacement Procedure
IMPORTANT; Determine whether all equipment connected to the ASXlOO System must be turned off prior to shut­
ting off water supply from filters.

If required, turn off equipment.
Turn OFF water to ASXlOO System by closing Inlet Ball Valve.
Press the red button to release pressure.
Remove housing(s) - use filter wrench if necessary.
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.
Insert new cartridge(s) into filter housings. Match cartridge model numbers to model
numbers on bracket.
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.
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.
Open the flush valve downline from the filter housing (if equipped) and flush the new
cartridges to drain or bucket for five (5) minutes or until water runs clear. If no flush
valve is present, disconnect line from equipment to flush to drain.
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.
Record filter change on the service log.
