Operation
With adequate pressure, normal operation of the ScaleX2
®
System is completely automatic. Dependable operation
involves only monitoring of outlet pressure, periodic filter changes and service documentation.
Pressure Gauge Monitoring
Periodically monitor the pressure gauge on the ScaleX2
®
unit. If the needle on the gauge ever enters the red zone, it
may be an indication that the filters have become clogged with sediment. Ideally, the pressure should never drop into
the red zone.
Filter Change Frequency
Several situations will mandate filter changes. Complete filter sets should be
changed when any of the following apply:
• Six (6) to twelve (12) Months have passed since unit installation or previous
filter change.
• Reduced water flow.
• Pressure gauge needle enters the red zone or drops below pressure required
for equipment operation.
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 recom
-
mendations.
Filter Cartridge Replacement Procedure
IMPORTANT: Determine whether all equipment connected to the ScaleX2
®
System
must be turned off prior to shutting off water supply from filters.
1. If required, turn off equipment.
2. Turn OFF water to ScaleX2
®
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 hous-
ings 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 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 ten (10) minutes or until wa
-
ter 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 equip
-
ment may cause serious damage.
11. Record filter change.

Maintenance
The only routine maintenance your ScaleX2
®
System should ever require is periodic filter cartridge changes or
replacement sump O-rings. Filter changes are necessary for optimum performance of your foodservice equipment. If
the system sizing recommendations have been followed, the ScaleX2
®
System is designed to provide a six (6) month
filter- replacement interval on most tap water for the CTO-20 cartridge, and the ScaleX2
®
Cartridge should last one (1)
year..
10. Connect tubing to equipment. Open all water supply valves and check for leaks.
11. If there are no leaks, turn on equipment and check for normal operation.
12. Attach the Service Log to the Installed OptiPure System and fill in install date.
