PERFORMANCE INDICATOR
SMARTAP®WATER FLOW MONITOR
The optional Smartap®Monitor indicates filter cartridge status by measuring the volume of water passing through the
Aquafier® Water Treatment System. When water is dispensed, it flows through the system actuating the monitor and
recording the elapsed time for each dispense. Monitor indication is based on the cumulative number of gallons passed
through the system (elapsed time multiplied by flow rate). A green light indicates filters are functioning normally.
A yellow light indicates filters are nearing useful capacity and should be replaced.
Disconnecting the battery from the clip resets the Monitor. Installing a new battery each time filter cartridges are replaced
ensures an accurate indication of system performance and a continuing supply of high quality drinking water.

INSTALLATION REQUIREMENTS
READ THIS ENTIRE INSTALLATION AND SERVICE GUIDE BEFORE BEGINNING INSTALLATION
This Aquafier®Drinking Water Treatment System is designed for ease of installation and serviceability.
It is constructed with the finest materials available.
Using these instructions and paying close attention to parameters outlined within "CONDITIONS FOR USE" detailed
on Page ii will ensure a successful installation.
This system must be installed in accordance with applicable city, state, and local plumbing codes.
To insure the system continues to operate at its optimum level,
it is necessary to have a routine maintenance and replacement schedule (Page 11).
The frequency at which filters need changing will depend on quality of feed water supply and level of system usage.
PREPARATION
1. Check that all appropriate components are packed
with your system (Page II, Figure 1). Refer to
applicable Component Parts Breakdown (Figure 7, 9,
or 10) for a complete list of its constituent parts.
2. Determine locations for component installation. Two
requirements for consideration are: access to cold
water supply line and to household sink. Specific
requirements are detailed in Table 1.
PRODUCT WATER FAUCET FILTRATION MODULE
Faucet may be installed in any convenient location.
Make sure underside of location is free of obstructions.
Module may be installed under a sink or in any convenient
location. within 15 feet of source water supply and faucet

1
INTER-COMPONENT CONNECTIONS
Connections between the cold water supply line, filtration unit, product water faucet, and optional accessories are
accomplished using plastic tubing and push-together quick-connect type fittings.
PLASTIC TUBING
1. Cut tube ends square and straight. Do not deform
the tube (i.e., cause tube to compress its diameter so
it is no longer round).
2. Make sure the outer surface of the tube is clear of
marks or scratches for a length equal to twice the
tube diameter. This allows the "O" ring to seat
properly against the tube.
3. Avoid sharp changes in direction when routing the
tubing. Sharp turns cause the tubing to flex and
deform which reduces its flow capacity and may
increase lateral stress on the fittings, causing leaks.
QUICK-CONNECT FITTINGS
Fittings consist of two parts: a Body and a colored Collet.
The Collet color corresponds to the tubing color to be
used at that connection (See Figure 2A.).
1. To install a tube, push it through Collet until it seats
firmly at bottom of fitting (Figures 2.A. and 2.B.).
2. To remove a tube, push and hold the Collet against
the Body while pulling the tube out (Figure 2.C.).
NOTE: Systems are shipped with a plug in each fitting
(prevents leakage of sanitizing fluid). Remove a
plug in the same manner as a tube.
A. Push tube through Collet into Body B. Tube must seat firmly at bottom of fitting C. Push Collet against Body to release tube

PRODUCT WATER FAUCET SITE PREPARATION
Refer to Faucet Installation Instructions (Pages 6 and 8) for site location and mounting hole
specifications.
Primary considerations for site selection are convenience of use and an open area under sink.
Always check underside of selected location for obstructions.
PORCELAIN/ENAMEL OVER STEEL
OR CAST IRON SINKS
NOTE: A heavy duty, variable speed drill motor is
recommended for this procedure.
Use of a spring-loaded porcelain drill set is
strongly recommended (Figure 5).
Plastic sleeve supplied on pilot drill (Figure 5.A.)
is to be positioned on drill bit against drill chuck.
This prevents chuck from contacting porcelain
after pilot hole has been completed.
Suggestion: Practice on discarded sinks to familiarize
yourself with operation of porcelain cutter kit.
CAUTION: Avoid high motor R.P.M. during initial
penetration of porcelain, as high drill speed
will cause excessive chipping.
1. Using carbide tipped bit with plastic sleeve (Figure
5.A.), drill pilot hole completely through porcelain and
metal underneath.
2. Place spring-loaded porcelain saw (Figure 5.B.) into
drill chuck. Make sure pilot guide is inserted tightly.
Insert pilot guide into pilot hole. Push down gently on
drill motor to apply light pressure to porcelain surface.
Start drill motor turning as slowly as possible.
After initial cut has started, motor speed may be
gradually increased. The cut may require three to
four minutes to complete. Going faster could result in
excessive chipping. Be sure a complete ring has
been cut through porcelain to material underneath.
3. Place finish hole saw (Figure 5.C.) into drill chuck.
Make sure pilot guide is inserted tightly. Insert pilot
guide into pilot hole. Begin cut using a slow speed
and light pressure until porcelain (inside ring cut in
Step 2) has been penetrated to material underneath.
4. Remove saw from hole and clean all debris from
porcelain surface. Reinsert saw into hole and cut
through remaining material.
TILE COUNTER TOP
1. Follow procedures detailed in section labeled
"Porcelain/Enamel Over Steel" (substitute "tile" for
"Porcelain" in instructions).
STAINLESS STEEL SINK
1. Use a center punch to make a small indentation to
mark center of desired location.
2. Drill a pilot hole with a 1/8" metal drill bit, then enlarge
hole with a 3/8" metal drill bit.
3. Complete hole size by using a 1 1/4" chassis punch
available from your dealer (P/N 36201006).
NOTE: Installation hole is ready, install faucet.

CLEANING, SANITIZING, AND CARTRIDGE REPLACEMENT PROCEDURE
1. Mix a mild cleaning solution of dish soap and clean
potable water in the plastic bowl.
2. Shut feed water supply valve and open product water
faucet to relieve system pressure.
NOTE: Do not attempt to remove filter housings until water
flow stops. This reduces pressure inside the
system so housings may be safely removed.
3. Remove each filter housing by turning it counter-
clockwise. Remove each filter cartridge as its housing
is removed. Discard filters.
Icemaker:Transfer ice cubes from bin/tray to clean
freezer container for storage until procedure is done.
NOTE: Use sanitary rubber gloves for this procedure to
avoid contaminating sanitizing solution or filters.
Wear gloves whenever cleaning/ sanitizing system
components or handling new filter cartridges.
4. Remove filter housing "O" rings and wash them with
cleaning solution. Rinse them well with clean potable
water. Inspect the "O" rings for damage (i.e., nicks or
scratches). Replace damaged "O" rings.
NOTE: Use caution when cleaning module. Do not get the
Smartap®Flow Monitor electronics, wiring, or
connectors wet.
5. Clean filter housings and manifold ports, inside and
outside with washcloth and cleaning solution. Do not
use abrasive materials.
6. Rinse housings/manifold with clean potable water.
7. Inspect manifold and filter housing "O" ring groove
area for damage (i.e., nicks or scratches). Replace
damaged components.
8. Place a small amount of "O" ring lubricant over the
surface of the filter housing "O" ring. Install the "O" ring
into the filter housing groove.
TO SANITIZE SYSTEM: Complete Steps 9-29.
TO INSTALL FILTERS: Complete Steps 17-29.
CAUTION: WEAR SAFETY GLASSES WHILE
PERFORMING THIS PROCEDURE.
CAUTION: EXCESSIVE CONCENTRATIONS OF
BLEACH WILL DAMAGE PLASTIC AND
RUBBER COMPONENTS. Rinse all parts
that contact bleach thoroughly with clean
potable water.
CAUTION: Read the "WARNINGS" on the bleach
container before using.
CAUTION: Handle sanitizing solution carefully. Avoid
contact with unprotected areas.
9. Mix sanitizing solution of 1.5 ml (1/3 teaspoon) of
household bleach and 3.8 L (1 gallon) of clean, potable
water in the bucket. Mix the solution well.
10. Add 236 ml (one cup or 8 oz.) of sanitizing solution to
each of the filter housings and install them onto the
manifold (do not install filters at this time). Tighten
each filter housing by hand only.
NOTE: TIGHTEN FILTER HOUSINGS BY HAND
ONLY. Do not use tools as they will over-
tighten and damage housings.
11. Slowly open the feed water supply valve.
12. Open product water faucet. Keep open for 5 seconds
after water starts coming out.
13. Close the product water faucet.
14. Wait 30 minutes, open product water faucet and let
water flow 5 minutes.
15. After 5 minutes, close feed water supply valve and
allow water to flow until system pressure is relieved.
NOTE: Do not attempt to remove filter housings until water
flow stops. This reduces pressure inside the
system so housings may be safely removed.
16. Remove the filter housings and dispose of the water.
Rinse housings and manifold ports thoroughly with
clean potable water.
NOTE: Do not remove protective plastic bag from filters.
Open the top of the bag only enough to expose the
top cap and "O" rings. Place a small amount of
“O” ring lubricant on surface of each “O” ring.
17. Install the filter cartridges. Hold cartridge by its
protective plastic bag and insert the cartridge into the
manifold turning it 1/2 turn as it enters the port (See
Page II, Figure 1 for location of each cartridge).
Slide bag from cartridge and discard. Replace each
filter housing as each cartridge is installed.
NOTE: TIGHTEN FILTER HOUSINGS BY HAND
ONLY. Do not use tools as they will over-
tighten and damage housings.

CLEANING, SANITIZING, AND CARTRIDGE REPLACEMENT
NO WATER FLOW MONITOR:
Complete Steps 26 - 29
OPTIONAL SMARTAP®WATER FLOW MONITOR:
Complete Steps 18 – 29
NOTE: The water flow monitor and battery are mounted
inside the manifold cover.
Monitor must be reset to zero each time system is
serviced and cartridges replaced.
If monitor is not reset, there is no way to determine
when filters were changed or if the system is still
operating within specifications.
Monitor is reset when the battery is disconnected
from the clip.
Installing a new battery when filter cartridges are
replaced ensures an accurate indication of system
performance and a continuing supply of high
quality drinking water.
Failure to replace battery may result in yellow light
when system is reconnected.
Use caution when working with module. The
wiring therein connects the control board to the
sending unit. If these wires are damaged, the
monitor will not function.
Do not get the monitor components wet (includes
circuit board, phone jack, and battery connections).
18. Loosen three mounting bracket screws. Gently pull
module cover up and away from module body.
19. Disconnect the battery. The connection to the battery
is a snap type connector (See Figure 11).
20. Remove the battery by sliding it out of its holder.
21. Replace the battery with a new alkaline 9-volt transistor
battery (P/N 31300001).
22. Carefully slide the battery into its holder.
NOTE: Use caution when reconnecting the battery (See
Figure 11).
23. Reconnect the battery by pressing the clip onto the
battery terminals.
24. Replace the module cover and tighten bracket screws.
25. Turn feed water valve slowly to the open position.
26. To test the connections, activate the Smartap®monitor
by pressing the test button or opening the product
water faucet. If an indicator light illuminates,
connections are good.
27. Open product water (and extra point-of-use) faucet.
Let water flow until all air has been expelled from
system.
28. Close product water (and extra point-of-use) faucet. In
5 minutes, check the connections for leaks and correct
if necessary.
Icemaker: Let the tray/bin fill with ice cubes. Discard
all ice cubes to the drain. This flushes sanitizing
solution from the lines to the icemaker.
29. Open product water (and extra point-of-use) faucet.
Let the water flow for 10 minutes. This will expel any
remaining air from the system.
NOTE: The system is ready to use. Should there be any
aftertaste or odor to the water or ice cubes, repeat
Step 29.
