DO NOT DISCARD THIS MANUAL AFTER INSTALLATION. THIS MANUAL CONTAINS
IMPORTANT OPERATION, MAINTENANCE AND PRECAUTIONARY INFORMATION.
PLEASE PRESENT THIS MANUAL TO USER/OPERATOR/OWNER AFTER INSTALLATION.
IT IS STRONGLY ENCOURAGED THAT YOU READ THIS MANUAL BEFORE INSTALLING
SYSTEM TO ENSURE THE BEST POSSIBLE INSTALLATION.
INSTALLATION MUST CONFORM TO ALL LOCAL AND STATE PLUMBING CODES AND
REGULATIONS.
CONNECT SYSTEM TO COLD WATER SUPPLY ONLY. WATER TEMP. CAN NOT EXCEED
100°F/38°C.
SYSTEM MUST BE INSTALLED IN A VERTICAL AND UPRIGHT POSITION.
SCALEX2® SYSTEMS MUST NOT BE USED IN CONJUNCTION WITH POLYPHOSPHATE OR
ANY OTHER SCALE INHIBITOR.
DO NOT INSTALL FILTERS DOWNLINE FROM THE SCALEX2® SYSTEM. SCALEX2® MUST
BE THE LAST FILTER SYSTEM BEFORE THE EQUIPMENT.
DO NOT USE WITH WATER THAT IS MICROBIOLOGICALLY UNSAFE OR OF UNKNOWN
QUALITY WITHOUT ADEQUATE DISINFECTION BEFORE OR AFTER THE SYSTEM.
FAILURE TO CHANGE CARTRIDGES PER RECOMMENDED INTERVALS WITH OPTIPURE
REPLACEMENT CARTRIDGES MAY LEAD TO SYSTEM FAILURE AND PROPERTY DAMAGE.
Introduction
Your new OptiPure ScaleX2® FoodService Filtration System will cleanse and 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.
System Specications
Maximum Pressure: 125 psi/8.6 bar Maximum Temperature: 100°F/38°C, Min.: 35°F/2°C
Capacity: Change the CTO (pre-filter) cartridge at gallon rating, or at least every 6 months or
when pressure gauge needle enters the red zone on the outlet gauge while water is flowing
through the filter system under normal operating conditions. The SCLX2 cartridge does not
have a grain removal capacity; however, naturally occurring organics present in the water
will gradually degrade the effectiveness of this cartridge. Change the SCLX2 cartridge at
least once a year.
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 o 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.
Model SX2-21
Capacity: 15,000 gals/56,800 L
Service Flow Rate: 1.5 gpm/5.7 lpm
Inlet/Outlet: 1/2” FNPT
Model SX2-22
Capacity: 30,000 gals/113,600 L
Service Flow Rate: 3 gpm/11.3 lpm
Inlet/Outlet: 1/2” FNPT
• 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 dicult 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 aected by water.
Installation Procedure
1. Turn o all equipment to be fed by the OptiPure System. Locate water supply cut-o
valve and turn o.
2. Determine if water line has an existing water treatment system. If so, examine system
for use of polyphospate or other scale inhibitors. ScaleX2
®
will not be eective 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 OptiPure System on a wall stud or suitable mounting material spanning wall
studs. System must be vertical and upright.
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 OptiPure 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 ten (10) minutes at the specied
system ow rate to allow air and any carbon nes to escape. NOTE: NO ACTIVATION IS
