IMPORTANT SAFETY INFORMATION (continued)
Protect from becoming dry
If the membrane dries out, irreversible damage to the Ultra
Filter membrane may result. Protect the filter from becoming
dry by keeping it wet and sealed at all times.
Protect from freezing
If the Ultra Filter membrane freezes during operation or stor-
age, irreversible damage to the membrane and brittle cracking
of the cartridge or housing may result.
Protect from direct sunlight or other UV sources
Avoid long-term exposure to direct sunlight or other UV
sources. The Ultra Filter should be stored in a dark location.
Protect from high temperatures or abrupt variation in
temperature
The maximum operating temperature is 104°F (40°C). Avoid
abrupt variations in temperature. Any temperature variation
should be made slowly.
Protect from rough handling or dropping
Mechanical damage, external breakage, and/or internal break-
age of the filter can result if the system is dropped or bumped.
Handle with care at all times during transportation and instal-
lation.
Protect from organic solvents and concentrated acids
Prevent any and all contact of the membrane with strong sol-
vents, solvents containing chlorine, or concentrated acids. Do
NOT use strong solvents or concentrated acids on any plastic
parts of the filter system. Examples of some solvents to avoid:
acetone, methyl acetate (nail polish remover); hexane (spot
removers); turpentine, toluene (paint thinners); dry cleaning
solutions, insecticides.
Protect from abrasive material
The membranes must be protected from abrasive materials
like shavings left in a pipe. Abrasive materials in contact with
the membrane can cause irreversible damage to the mem-
brane. All pipes must be flushed clean before installing the fil-
ter. All plastic parts of the filter system must be protected from
sharp objects like knives, sand paper, or other tools. Cutting
or nicking a plastic part can weaken it and cause a leak. Do
NOT use abrasive cleansers on any plastic parts.
Protect from water hammer
The system must be protected from shock, pressure surges,
or pulsation that may occur inside water pipes. Water ham-
mer occurs in pipes when a valve or faucet shuts quickly.
Install a water hammer arrestor (pressure vessel containing
compressed air separated from the water by a diaphragm) to
reduce pressure shock.
CAUTION
This equipment is to be installed to comply with the
basic plumbing code of the Building Officials and Code
Administrators, Inc. (BOCA) and the Food Service
Sanitation Manual of the Food and Drug Administration
(FDA).
CAUTION
Water Flow Regulator Assemblies are NOT interchange-
able. Operating the system with the wrong Water Flow
Regulator or without a regulator can damage the sys-
tem, cause personal injury, and voids the warranty!

INSTALLATION (continued)
INLET WATER PLUMBING
If desired, a “T” or Cross Fitting with cap or plug can be
installed between the Inlet Valve and the System Inlet. This
fitting can be used for draining and sanitizing the system and
downstream plumbing.
The plumbing leading to the system must be flushed clear of
all debris before connecting to the system inlet. Hold a bucket
at the inlet water line and slowly open the inlet water valve.
Allow the pipe to flush until all debris is removed.

DRAIN LINE PLUMBING
The drain line flushes particle buildup out of the system during
self cleaning and must be able to support the flow rate when
the system flushes.
The flow rate from the flush depends on the inlet water pres-
sure, inlet pipe size, and system selected. The drain opening
should be as large or larger than the inlet plumbing line.
The drain line leading out of the system should be as short as
possible, sloping downward without kinks or loops. Be sure
the drain used is not blocked or restricted.
Protect the system from possible back contamination by
installing an air gap between the drain connection of the
system and the drain (Figure 3). This gap in the line, with no
physical contact between the system and drain, prevents con-
tamination of the system in the event of a backed-up drain.
NOTE: Make sure the end of the drain line is positioned
and secured at least 2 inches above the drain so that the
water flow is directed into the drain without splashing.
ATTACH THE SMART CONTROLLER AND WIRING
HARNESSES
1. Using the provided Velcro®fastener, connect the Smart
Controller to the system as shown in Figure 2.
2. Connect the two wiring harness connectors to the
appropriate points on the bottom of the Smart Controller
(Figure 4).
NOTE: Do NOT plug the power transformer into the
SMART controller at this time. Mount the system to the
wall first before attaching the power.

14. Install the Snap Ring by guiding the non-lugged end
into the groove first, pushing outward and working
around the ring until it snaps into place.
NOTE: Make sure that the Snap Ring is fully seated
before turning the water on.
15. Re-attach the elbow fitting that was disconnected in
Step 5 (Figure 13 and inset). Push the fitting onto the
tubing until it comes into contact with the internal tubing
stop. Rotating the fitting slightly during installation helps
make the connection slide past the O-ring seal.
NOTE: Make sure the fitting is completely inserted onto
the tubing past the O-ring. A loose connection results in
leaking at the point of connection.
16. Rinse the new Ultra Filter cartridge before placing the
system back into operation. Follow the Rinsing the
Ultra Filter Cartridge and Sanitizing the System
and Lines procedures in the Installation section of this
manual to complete the cartridge change.
17. When rinsing is complete, repressurize the system.

7. Empty any water into a drain and discard the old
Carbon Element. See Figure 14.
8. Inspect the O-ring on the Carbon Element Housing.
Replace the O-ring if it is cracked, twisted, or missing.
9. Lubricate the O-ring with an approved food grade lubri-
cant and install into the Carbon Element Housing.
10. Install the new Carbon Element into the Carbon
Element Housing.
NOTE: Make sure the End Seal gaskets are in place on
both ends of the Carbon Element. The gasket is retained
on the end of the element in the recessed groove. Be
careful that the gasket does not fall off the element while
placing the element into the bowl.
11. Screw the Carbon Element Housing (containing the
Carbon Element) into place. Tighten the Carbon
Element Housing until it stops. The housing will come to
a hard stop at the end of the thread. Use a filter wrench
if necessary.
12. Direct the outlet of the system to drain.
NOTE: It is important to direct the system outlet to drain
as the water resulting from Steps 13 through 17 should
NOT be used.
13. Next, repressurize the system using the “08"program.
To enter the program, press and hold (in order) the
