Hardness Conversion: 1 grain per gallon equals 17.1 ppm or mg/l. e.g. 10 grains of hardness is equal to 171
mg.l of hardness.
The formula to determine cartridge life span is:
(Grains Capacity of Filter/grains per gallon) x (ounces per gallon/ounces per serving)
An example: If the QTSFT-3 was installed on a system with feedwater that contains 10 grains of hardness and the
serving size is 2 ounces, the expected life spane would be: (4500 grains/10 grains) X (128 ozs./2ozs.) = 450 gallons
treated x 64 servings/gallon = 28,800 servings. Or you could simply say 450 gallons of water is treated regardless of
serving size.
Caution: If the equipment has an automatic cleaning cycle or other use for the feedwater, the amount of water used
must added to the treated water consumption and the grains of capacity. In cases where the water has above normal
sediment or chlorine, or the hardness varies due to seasonal changes or drought, the rated capacity of the cartridges
may be reduced. To acheive the maximum protection for the equipent it is recommended that the hardness be
monitored until a standard can be established.

Do NOT allow system to freeze. Turn off water supply to housing and drain housing if temperature falls below 33°F.
Do NOT install system in direct sunlight or where system is exposed to harsh chemicals or may be subjected to
being struck by moving equipment, carts, mops or any other item that may cause damage.
IF water hammer is evident, install water hammer arrestors before OptiPure unit.
Installation Procedure
1. Turn off all equipment to be fed by the OptiPure System.
2. Locate water supply cut-off valve and turn off.
3. Install a minimum 3/8” full-flow 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.
5. Run 3/8” Polyethylene tubing from the full-flow ball valve at the tap water source to the inlet ball valve on the
left side of the OptiPure system. The connection is a 3/8” Parker True-Seal connection that is a push fit.
NOTE: Make sure tubing is cut square and clean with no burrs before inserting into True-Seal connection.
6. Select the appropriate size tubing for the equipment being fed and connect it to the outlet of the OptiPure
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 flushing the system. As an option, a flush valve in a tee on the
outlet side of the OptiPure system can be installed in the line to facilitate flushing when changing filters.
7. With OptiPure inlet valve closed, slowly open the full-flow ball valve at the tap water source. Check for leaks.
8. If a flush 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 flush through
system for 10 minutes at the specified system flow rate to allow air and any carbon fines to escape. NOTE:
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 no leaks turn on equipment and check for normal operation.
12. IMPORTANT: Document installation date; measure water hardness of water supply and filtered water.
Calculate projected filter cartridge change date and document.
With adequate pressure, normal operation of the OptiPure System is
completely automatic. Dependable operation involves only monitoring of
water hardness, periodic filter changes and service documentation.
The only routine maintenance your OptiPure System should ever require
is periodic filter cartridge changes. Filter changes are necessary for optimum performance of your foodservice equipment. If the system sizing
recommendations have been followed the OptiPure System is designed
to provide soft water for the rated capacity of the system.
Filter Change Frequency
Several situations will mandate filter changes. Complete filter sets
should be changed when any of the following apply:
• Six (6) Months have passed since unit installation or previous filter
• Reduced water flow.
• When hardness minerals are no longer removed.
If filter change frequency is less than capacity to remove hardness, it
may be necessary to add additional prefiltration or evaluate system sizing recommendations.
Filter Cartridge Replacement Procedure
IMPORTANT: Determine whether all equipment connected to the
OptiPure System must be turned off prior to shutting off water supply
from filters.
1. Close inlet ball valve.
2. Relieve pressure downline by opening flush valve or briefly actuating equipment.
3. Turn cartridge to the left 1/4 turn until it stops.
4. Pull down on the cartridge until it clears head. Discard old cartridge.
5. Line up the upward-arrow on the new cartridge with the upward
pointing arrow on the head.
6. Push cartridge up into head until it stops and turn to right until it
stops. (The upward-arrow on the cartridge should align with the
downward-arrow on the head).
7. Open the inlet ball valve.
8. Open down-stream flush valve to flush new cartridge at the specified flow rate for a minimum of ten (10) minutes.

Hardness Test Strip (2/pk)
Hardness Testing
For your convenience we have included two hardness
test strips in this installation kit for determining the
hardness of your feedwater. Due to the fact that tap
water varies dramatically even within the same city we
strongly recommend the you test the hardness and
calculate the capacity of the system. This will provide
you with the maximum protection for your equipment.
The test procedure is very simple and will only take a
few seconds to complete. Furthermore, it would be
prudent to periodically measure feedwater and treated
water hardness to confirm that the feedwater hardness
has remained consistent and that your system has not
exceeded capacity.
Replacement Filter Cartridges
OptiPure Filter Systems are designed, tested,
and certified with OptiPure filter cartridges with
proven performance, size and operating capacities. Use of replacement cartridges other than
those specified will void warranties, certifications
and may compromise equipment protection,
water quality and cartridge life.
Test Procedure:
1. Flush wter from the supply line that you will be
using to supply the QTSFT for several minutes.
2. Fill a clean cup with the water from the line after
3. Dip the test strip into the water sample for one (1)
second, remove and immediately match with the
closest color on the strip package for total hardness
(TH) as parts per million (ppm) or grains per gallon
(gpg). Color is stable for 1 minute.
4. After installation of the QSFT and the unit has been
flushed, check the hardness of the treated water
using the same procedure in steps 1-3. It should be
zero-1 grain per gallon.
Doing this test will confirm that the QTSFT is performing and will provide you with the peace of mind that
your equipment is protected from hardness scale.
FilterTrak - Filter System Management
The single biggest problem with filter systems is
the lack of attention after the system is installed.
Many times the equipment supplied by the
filter systems has a service problem related to
water because the filter system has not been
maintained. This is simply because personnel
in the establishment change and it becomes difficult to keep track of what filters are needed and
when. FilterTrak eliminates this problem since
it automatically notifies users when a scheduled
filter change is due and what filter cartridges are
needed via mail, fax, email or autoship.
OptiPure warrants the quality of workmanship of their system components and assembly, except for replacement
cartridges and membranes, for a period of 36 months. OptiPure Systems are designed, tested and certified with
OptiPure cartridges. Use of replacement cartridges or parts other than those specified will void warranties and Certifications, and compromise equipment protection, water quality and cartridge life.
