INSTALLATION
SAVE THESE INSTRUCTIONS
1. Determine location to install equipment. Make
sure the unit will be on a flat surface.
2. If sand, silt, or turbidity is present, install a
separate prefilter.
NOTE: Sediment filtration is recommended before
the water softener, particularly in areas with known
sediment issues or on a private water supplies.
NOTE: If the peak flow rate required is unknown, a
prefilter with a minimum of 1.25" connections should
be used. Filters with 5 micron nominal ratings should
be considered the standard in food service
applications.
By-Pass Valve Kit Installation
3. If the optional by-pass valve kit is being
installed, continue with steps listed below. If bypass valve kit is not being installed - proceed to
step 24.
4. To install by-pass valve determine which port on
the by-pass valve (Port A or Port B) to plumb
the raw water connection to.
5. Determine which port on the by-pass valve (Port
C or Port D) to connect the softener.

6. Verify the by-pass valve is in the by-pass
position. Turn by-pass handle to reveal yellow
by-pass segment.
7. Remove the by-pass valve handle by pulling it
away from the by-pass valve body.
9. Locate patch decal provided with by-pass valve
kit.
10. Remove patch decal from paper lining and
apply to body of the by-pass valve based on the
specific installation using Table 1.
NOTE: For use in A-D or B-D configuration, it will be
necessary to cut patch.
8. The five position valve has two installation
configuration options. Photo below shows the
crossover and parallel configurations as the
valve is shipped.

11. Align the handle with the shaft until handle
slides onto shaft. Push down on handle until it
snaps into place.
NOTE: The handle is keyed allowing it to go on the
shaft only one way. Failing to perform above
procedure can result in breaking the shaft inside the
handle. Do not force handle onto shaft.
17. Apply a liberal amount of silicone to the four Orings and install on the two end spaces on both
Port C and Port D.
NOTE: When installing a plastic component in line, it
is recommended that grounding straps be put in
place before the lines are actually cut to ensure the
ground is never broken.
12. Prepare plumbing by roughing in.
13. Connect the inlet/outlet adapters to the
plumbing. Solder or glue adapters to pipe as
applicable.
NOTE: Do not solder adapters while in the by-pass
valve.
NOTE: Care should be taken during the installation
process to assure that solder flux does not come in
contact with the media tanks, the control module,
and related components.
14. After all plumbing is completed and before
connecting any equipment, flush both inlet and
outlet lines by opening the raw water inlet valve
and allowing water to rinse out and debris in the
line.
15. Close the raw water line when complete.
16. Locate from the by-pass kit the two elbows,
four O-rings, two E-Clips and silicone packet.
18. Insert mesh screens into left and right elbows.
19. Locate from the by pass kit the four O-rings, two
E-Clips and silicone packet

20. Apply a liberal amount of silicone to the four Orings and install them on the two outermost
groves on both elbows
NOTE: Elbows are marked left (L) and right (R).
When applying to by-pass valve be certain to install
in correct location based on left/right orientation.
By-Pass Valving Installation
NOTE: If optional by-pass valve kit is not installed - it
is recommended that by-pass valving be installed.
To install by-pass valving - follow steps listed below.
24. Determine location to install equipment. Make
sure the unit will be on a flat surface.
25. If sand, silt, or turbidity is present, install a
separate prefilter.
NOTE: Sediment filtration is recommended before
the water softener, particularly in areas with known
sediment issues or on a private water supplies.
NOTE: If the peak flow rate required is unknown, a
prefilter with a minimum of 1.25" connections should
be used. Filters with 5 micron nominal ratings should
be considered the standard in food service
applications.
26. Install by-pass valving. Be certain to note the
inlet and outlet arrows on the valve head.
27. Connect the inlet/outlet adapters leading to the
softener using the proper size plumbing.
28. Plumb as necessary to accommodate the bypass valving and to complete the installation.
NOTE: Make sure to align the center slot (the slot
with the small triangle underneath it) with the outside
of the by pass valve.
21. Connect elbows from the by-pass valve to
softener using E-clips. Press E-clips until they
securely snap in place.
22. Connect the by-pass valve to the inlet/outlet
adapters. Press E-clips until they securely snap
in place.
23. Plumb as necessary to accommodate the bypass valve and to complete the installation.
Proceed to step 31.
NOTE: Actual installation of by-pass valving may
vary from installation to installation. Be sure to follow
state and local codes.
NOTE: When installing a plastic component in line, it
is recommended that grounding straps be put in
place before the lines are actually cut to ensure the
ground is never broken.
NOTE: Do not solder brass adapters while inserted
in the module base. Damage to plastic and ruber
parts may result due to the heat. In addition, the
materials used in the soldering process may attack
certain types of plastics.
NOTE: Care should be taken during the installation
process to assure that solder flux do not come in
contact with the media tanks, the control module,
and related components.
