Introduction
Your new OptiPure ScaleX2® FoodService Filtration System will condition the tap water, providing optimum water
characteristics for specied applications. Results include reduced equipment-maintenance requirements, longer
equipment life and improved quality and consistency of your products. Proper system installation and routine lter
changes ensure years of trouble-free operation and performance.
The OptiPure System is built with the nest and most advanced materials. Each system is quality inspected and
pressure-tested prior to shipment. With proper installation and routine maintenance, you should have years of
trouble-free operation.
Please refer to this manual when performing routine lter changes. The instructions make periodic maintenance quick
and easy, and ensure that you should receive maximum benet from your system.
Operating Specications
Maximum Pressure: 125 psi/8.6 bar Maximum Temperature: 100°F/38°C
Minimum Temperature: 35°F/2°C
Installation Precautions
• Do NOT install system on line pressure above 125 psi.
• Do NOT install the system backwards with the feed water line connected to the outlet.
• Do NOT use liquid pipe compounds for tting connections. USE two to three wraps of teon tape.
• Do NOT solder plumbing connections attached to lter housing or inlet valve. Inlet valve and lter housing will
be damaged by high temperature.
•
Do NOT allow system to freeze. Turn off water supply to housing and drain housing if temperature falls below 32°F.
• Do NOT install system in direct sunlight or where system is exposed to harsh chemicals, or where it may be
subjected to being struck by moving equipment, carts, mops or any other item that may cause damage.
• ALLOW a minimum of 3” under the housing to allow for lter replacement.
• IF water hammer is evident, install water hammer arrestors before OptiPure unit.
• Do NOT overtighten tting connections into inlet valve our housing outlet.
• Always back-up valves and ttings with a wrench when installing a tting to avoid turning the valve.
• Do NOT install the unit behind equipment where it may be difcult to access the system for lter replacement.

Position the OptiPure unit in a suitable location. The direction of ow through the OptiPure unit is always left to right;
keep this in mind when determining installation location. Do NOT mount the OptiPure system near any source of
heat. Also, do not mount the system above any device or area that would be adversely affected by water.
Installation Procedure
1. Turn off all equipment to be fed by the ScaleX2® System, locate water supply cut-off valve and turn off.
2. Determine if water line has an existing water treatment system. If so, examine system for use of polyphosphate
or other scale inhibitors. ScaleX2® will not be effective if used in conjunction with other scale inhibitors. Remove
the scale inhibitors from the water line or discontinue installation.
3. Install a 1/2” full-ow ball valve on the water supply side that will feed the water system.
4. Anchor the ScaleX2® System on a wall stud or suitable mounting material spanning wall studs. System
must be upright and vertical.
5. Run a suitable line from the 1/2” full-ow ball valve at the tap water source to the inlet ball valve on the left side
of the ScaleX2® system. Use 2-3 wraps of teon tape and brace the inlet ball valve on the system with a wrench
when connecting the feed water line. NOTE: DO NOT OVERTIGHTEN CONNECTION FITTING INTO BALL
VALVE.
6. Select the appropriate size tubing for the equipment being fed and connect it to the outlet of the ScaleX2®
System. NOTE: DO NOT connect the tubing to the equipment at this time. Prior to making connection to the
equipment this line will be used to facilitate ushing the system. As an option, a drain valve in a tee on the outlet
side of the ScaleX2® system could be provided in the line to facilitate ushing when changing lters.
7. With System inlet valve closed, slowly open the 1/2” full-ow ball valve at the tap water source. Check for leaks.
8. If a drain valve was not installed on the outlet side of the system, hold the tubing that will connect to equipment in a clean bucket or over sink or drain. Open the system inlet feed valve and allow water to ush through
system for 10 minutes at the specied system ow rate to allow air and any carbon nes to escape. NOTE:
NO ACTIVATION IS REQUIRED FOR THE OPTIPURE SYSTEM TO PERFORM PROPERLY. FLUSHING IS
RECOMMENDED TO ALLOW AIR TO ESCAPE THE SYSTEM AND REMOVE ANY CARBON FINES PRIOR
TO CONNECTING TO EQUIPMENT.
9. Make certain that the end of the tubing to be connected to the equipment is clean and sanitized.
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 ll in install date.

Operation
With adequate pressure, normal operation of the ScaleX2® System is completely automatic. Dependable operation
involves only periodic lter changes and service documentation.
Maintenance
The only routine maintenance your ScaleX2® System should ever require is
periodic lter 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 twelve (12) month lter replacement interval on most tap water.
Filter Change Frequency
Several situations will mandate lter changes. Complete lter sets should be
changed when any of the following apply:
• Twelve (12) Months have passed since unit installation or previous lter
change.
• Reduced water ow.
If lter change frequency is less than 12 months due to pressure drop, it may be
necessary to add additional preltration or evaluate system sizing recommenda-
tions.
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 lters.
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 lter 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 lter bowl of water. Let
stand 5 minutes, and then discard.
6. Insert new cartridges into lter housings. Match cartridge model numbers
to model numbers on bracket.
7. Make certain the O-ring is properly positioned and reinstall lter 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 ush valve downline from the lter housing (if equipped) and ush
the new cartridges to drain or bucket for ten (10) minutes or until water runs
clear. If no ush valve is present, disconnect line from equipment to ush
to drain.
10. VERY IMPORTANT: With water supply inlet valve OPEN and water ow
conrmed, turn on connected equipment. Failure to supply water to equip-
ment may cause serious damage.
11. Record lter change on the service log or at FilterTrak.
