MANY USES AND BENEFITS OF REVERSE OSMOSIS WATER

INTRODUCTION

CONTENTS OF PACKAGE

TOOLS & MATERIALS RECOMMENDED FOR NORMAL INSTALLATION

4

| Krystal Pure™ | Reverse Osmosis System Manual

1. Only use with potable water supplies (Water
must be microbiologically safe).

2. Installation of R/O system must Comply with
state and local laws and regulations.

3. Check for leaks after installation or service
as system is reaching standard operating pres­sure and temperature. Check for leaks peri­odically thereafter. A system may be inad­vertently moved or jarred while other items
are moved under the sink. If a fitting is acci­dentally loosened, a leak could result causing
damage to your cabinet.

4. Do not let system freeze. Allow to warm up
to room temperature before installing. Best to
be installed indoors with air temperature be­tween 60° - 85° F.

5. Attach to cold water supply only.

6. Never drain R/O tank completely without
first turning off the refrigerator ice maker.

7. Air-gap faucet may cause a slight noise at first
but noise should diminish in about a week. If
noise continues, adjusting drain clamp may
help reduce noise. Also, install faucet so
air-gap faucet hole will drain into the sink if
drain line gets plugged from obstruction in
the drain line.

8. This reverse osmosis system contains a re­placeable component critical to the efficien­cy of the system. Replacement of the reverse
osmosis component should be with one of
identical specifications, as defined by the
manufacturer, to assure the same efficiency
and contaminant reduction performance.

9. Failure to follow recommended service in­tervals or use of filters and parts other than
those recommended by the manufacturer
may void warranty.

10. Drain R/O tank completely at least twice a
year. If daily use averages less than a gallon
per day, drain every two weeks. (See page 3
for Many Uses).

11. We recommend having all porcelain/enam­el-coated sinks professionally drilled.

12. Sanitizing most R/O systems on a yearly basis
is important for reducing bacteria build-up.

13. All membrane performance and life cycles
may be affected by severe water conditions.
Varying mineral content like hardness and
iron will require varying filter change inter­vals. Some customers choose pretreatment
options like water softening or iron reduction
systems to protect the entire home.

STEP 1 POSITION SYSTEM

The R/O system needs both a water supply and
access to a drain. The R/O system is designed to
fit under most sinks. The kitchen sink is the most
common location for the R/O install. Remove all
system components from boxes and determine
the location for placement of the Filter Pac/R/O
module, tank, and faucet.

If you desire to hang the Filter Pac/R/O module,
use mounting screws, placing them to align with
holes in the bracket (make sure the cabinet wall

is thick enough to support the Filter Pac/R/O
module and that the mounting screws will not
pierce through the wall). Hang Filter Pac/R/O

module to assure sufficient space is allowed.
Remove Filter Pac/R/O module from the wall for
now and continue with install.

STEP 2 FAUCET INSTALLATION

1. Check for an extra hole in the sink. You must
drill a 1¼” hole for the faucet if the sink does
not have one.Determine Location of Faucet
Hole: Check underneath sink before drilling.
Make sure there are no obstructions. Drilling
a Stainless Steel Sink: Drill a 1¼” hole with a
hole saw or hole punch for an air-gap faucet.
Smooth out rough edges with a file if nec­essar y.Porcelain/Enamel-Coated Stainless

or Cast Iron Sink: The manufacturer recom­mends having this type of sink professionally
drilled because of possibility of chipping or

cracking. If you are attempting to drill, use ex­treme caution. Obtain the proper tools neces­sary to drill through the sink material. Follow
the drill manufacturers instructions for your
type of sink. Place an old towel under the

sink to catch any metal filings and to make
clean up easy. After drilling, clean up metal
filings quickly to avoid staining the porcelain.

2. Install Air-gap Faucet: Pre-assemble faucet

prior to installing on the sink. Place the white
spacer onto faucet stem flat side toward tub­ing and open end upward. Slide spacer up the
stem leaving enough room for the thickness of
the sink. Place the washer onto the stem and
thread on the 9/16” nut up to the spacer. At­tach the plastic 3/8” faucet adapter fitting to
the base of the faucet stem (Do not over-tight-

en) (see A in Figure 1 page 6).

3. Guide the (2) tubes and the faucet stem through
the hole on the sink until the faucet rests on
top of the sink. Center the faucet over the hole.
Position the faucet so the air-gap hole and the
faucet lever point toward the sink basin (in case
drain tube plugs causing water to spill out of
the air-gap hole). Insert the slotted washer un­der the sink between the white spacer and the
base of the sink. Tighten the 9/16” nut securing
the white spacer tight against the sink (see B in
Figure 1 page 6). Faucet may require reposition­ing before final tightening. Remove short pack­ing tubing from top of faucet and insert faucet
spout by pushing spout straight into the hole
until it seats.

STEP 3 EASY TAP ADAPTER INSTALLATION

Turn off cold water supply to the sink faucet
and relieve pressure by opening the cold water
faucet. (Repair any existing plumbing sink leaks
before continuing). Follow water supply from the
cold water supply valve, toward the sink faucet,
until you reach a coupling nut (may be at the

base of the faucet). Unscrew the coupling nut.
Place rubber washer into the plastic easy tap
faucet adapter and screw adapter onto location
of coupling nut. Hand-tighten, then tighten one
more complete turn with a wrench. Re-attach the
supply line to the adapter with the coupling nut.

Leave the cold water off.

CAUTION:

1. When tightening easy tap, make sure the tube
to which you are attaching the easy tap is not
twisted. Use two wrenches to hold existing
tube while tightening the easy tap adapter.

2. Examine existing cone shaped washer on wa­ter supply tube, adjust or replace if damaged
or worn (not included).

3. If self-piercing valve is used instead of easy

tap, attach to hard copper tubing only. Do not
over tighten screws (see instructions on pierc­ing valve package, not included).

NOTE: Push-In style fittings are designed for ease of use.
Simply push the tubing in until it seats. Give a tug on it to
make sure it is secure. Insert red locking clip between fit­ting and collar. If you need to remove the tubing, remove
the red locking clip, hold the locking ring collar against the
fitting while pulling out the tubing. No inserts or nuts are
used with the Push-In style fittings.

STEP 4 DRAIN SADDLE CLAMP
INSTALLATION

Location of Drain Clamp

1. Sink With Disposal: Select location to place
drain saddle clamp. Best choice is the verti­cal pipe as near the sink as possible making
certain that the drain clamp is above the hor­izontal garbage disposal waste pipe. When
connecting the black drain tube to drain saddle
clamp keep the tube run as straight as possible
and that there are no dips, loops, low spots or
kinks (See D in Figure 2 on page 7). Also, to
reduce noise, assure that R/O drain line enters
the vertical pipe from a direction other than the
direction of entry of the garbage disposal pipe.

Or

2. Sink Without Disposal: Best choice is the ver­tical pipe about 4” above the water level in
the trap.

To Install:

Drill a 3/8” hole through one side of the drain­pipe. Align the hole in the drain clamp with the
hole in the drainpipe. Tighten down the drain
clamp snugly so it will not move on drainpipe.

STEP 5 STORAGE TANK PREPARATION

1. Wrap the threads on top of the tank with 6
wraps of Teflon tape (do not use any type of
pipe compounds).

2. Screw tank ball valve onto the top of the
tank (approximately 4 to 5 full turns, do not
over-tighten). Check for leaks once R/O is
pressurized and while tank is filling and again
when tank is full.

3. Tank is pre-charged with air pressure. Tank
can be laid on its side if necessary (tank will
hold approximately 2 to 3 gallons of R/O wa­ter depending on water pressure, tank posi­tioning, and tank air pressure).

4. Tank pressure can be increased to improve wa­ter flow to the faucet or refrigerator. Air pres­sure can only be tested when tank is completely

empty of water. Air pressure of 5 PSI minimum,
12 PSI maximum is recommended. The higher
the air pressure the smaller the volume of water
the tank will hold. Pressure of 10-12 PSI may be
necessary to feed a line to the refrigerator. Over
pressurizing may ruin the tank.

STEP 6 TUBING CONNECTIONS

IMPORTANT: Fitting manufacturer requires fit-

tings to be re-checked after system reaches full
operating pressure and temperature, Re-tighten
and secure as necessary.

It is not recommended to shorten the length of
any tubes during installation (except black 3/8”
drain tube on air gap faucet). This will make fu­ture servicing easier.

1. ¼” White Supply Tube on Filter Pac/R/O mod­ule: Connect the supply (white) tube firmly
into the push-in port on the side of the easy
tap adapter installed on the cold water supply
line. OPTIONAL: If self-piercing valve is used,
connect to valve using brass nut, tubing sup­port, ferrule, and plastic insert (not included).

2. ¼” Red Drain Tube on Filter Pac/R/O module

- Air-Gap faucet system: Use the coupler from
the parts bag to connect the ¼” red drain tube
from the faucet to the red tube from Filter Pac/
R/O Module (See C in Figure 2 above). Push
firmly so tubes will not pull out of coupler or
leak. IMPORTANT: 1/4” red tubing MUST be
connected using the provided coupler or else
unit WILL NOT work properly.

3. 3/8” Black Drain Tube from Faucet: Connect
this tube to the black 3/8” drain clamp. (See D
in Figure 2). Tighten firmly so tube will not pull
out of drain clamp. IMPORTANT: Do not leave
excessive slack in drain tubing. Shorten tubing

so that it flows directly to the drain with no
dips, loops, low spots, or kinks. If not installed
correctly, water will be forced out the side air­gap hole of the faucet.

4. Post Filter Connection to Faucet: KR10: Con­nect the 3/8” blue tube on the front of the
post-filter bowl (labeled out) to the 3/8” push­in adapter fitting on the R/O faucet. KR15:
Connect the 3/8” blue tube on the back of the
post-filter bowl (labeled out) to the 3/8” push­in adapter fitting on the R/O faucet.

5. R/O Tank Connection: KR10: Connect the 3/8”
blue tube on the back of the post-filter bowl
(from the tee fitting) to the push-in ball valve
on top of the R/O storage tank. KR15: Connect
the 3/8” blue tube on the front of the post-filter
bowl (from the tee fitting) to the push-in ball
valve on top of the R/O storage tank.

STEP 7 SYSTEM START-UP PROCEDURES

Turn your sink cold water supply valve to the on
position while leaving the Filter Pac/R/O mod­ule and R/O tank ball valves in the off position
(horizontal, which is perpendicular to the valve).
Check for leaks and adjust as necessary.

1. Slowly turn Filter Pac/R/O module ball valve
to the on position (blue valve vertical, which
is in line with the valve). As water enters the
filter bowls and makes its way through the fil­ters to the membrane element you will hear
air escaping through the drain. This is normal.
Open R/O faucet on the sink until the water
starts coming out. (Water flow will only be a
trickle and may take up to 20 minutes before
water starts to come out of the faucet spout on
some units). Shut R/O faucet off and check for
leaks and adjust as necessary.

2. Open the tank ball valve by turning handle a ¼
turn toward the tubing. Let tank fill for 4 to 6
hours (if you are changing filters, your tank may
already be full, so you would not need to wait).
Then turn on R/O faucet and drain tank com­pletely, (approx. 5 minutes). Shut R/O faucet
off, allow tank to refill, and drain again in 4 to
6 hours. The R/O system is shipped with a food
grade preservative and must be flushed out pri­or to use. DO NOT DRINK THE R/O WATER

UNTIL TANK HAS BEEN DRAINED TWICE.

3. Shut R/O faucet off and let system fill again.
R/O water is now ready for use.

IMPORTANT: Check carefully for small leaks every
few hours for the first few days to assure there are
no leaks. It is wise on any R/O system to inspect for
leaks since the system sits unseen underneath your
sink and a small leak may not be detected with­out close inspection. Check for leaks occasionally
thereafter and make adjustments as necessary

STEP 8 REFRIGERATOR ICE MAKER
HOOK UP

1. If there is not an ice-line from the R/O to the
refrigerator, you may choose to run an ice-line
so that your ice and water dispenser will have
filtered water. If the distance from the refrig­erator to the R/O is more than 50 ft., we rec­ommend 3/8” polypropylene or polyethylene
tubing for best results. DO NOT USE COPPER
(Be sure you have the recommended water
pressure to your ice maker according to the
refrigerator manufacturer’s specifications.) 3/8”
tubing, a supplemental storage tank, more R/O
air pressure, or different usage patterns, may be
required to supply adequate pressure!

2. Connect tube (not included) to appropriate re­frigerator connection and to a plastic “T” fitting
(not included) spliced into the 3/8” blue tube
between the post filter and faucet. It is recom­mended to install a ball valve on the tube to the
refrigerator for service and start up purposes.
Keep ball valve off until start up procedures are
completed and R/O tank is completely full after
the second tank draining.

IMPORTANT: Never turn on icemaker before
R/O tank is full of water to avoid damaging refrig­erator solenoid. If your refrigerator has a water
dispenser in the door, upon initial start-up you
will need to depress the water supply lever 2 to 3
minutes before the water will dispense.

STEP 9 RECOMMENDED FILTER
SERVICE LIFE

The types of filters listed below vary depending
on R/O system style. The manufacturer provides
very high capacity carbon filters and replace­ment intervals are based on our filters. Other
filters may not have the same capacity as origi­nal factory filters and may not last as long. Water
conditions vary greatly by region and can affect
filter change intervals. For filter change interval
recommendations, follow the guidelines below.
If in doubt, contact the manufacturer.

Sediment Pre-filter: These are the only filter(s)
that you can visually inspect. They are white
when new and will turn dark with dirt and sedi­ment when changing is necessary. A water soft­ener will extend the life of the filter(s). Inspect ev­ery 6 months or sooner in bad water conditions.

Carbon Pre-filter: These filters should be
changed at least once a year. Changing these fil­ters is necessary to help insure membrane life and
water quality. Use of high capacity carbon block
filters is recommended. Granular carbon filters
are not recommended because they release ex­cessive carbon fines at initial start-up, which can
reduce the life of the membrane element.

R/O Membrane: The R/O membrane element is
a replaceable component critical for effective re­duction of TDS (Total Dissolved Solids). The R/O
membrane should be changed when TDS rejection
rate falls below 75%. The rejection rate should be
tested periodically to insure optimal performance.
The membrane typically lasts 2-5 years depending
on influent water quality and hardness. See perfor­mance indicator information listed below.*

Carbon Post-filter/Carbon M.A.P.™ Filter: These
filters need to be changed at least every 12
months to insure quality water. Do not wait until

taste is a problem.
*Performance indicator. The R/O system contains

a replaceable treatment component critical for ef­fective reduction of TDS (Total Dissolved Solids).
The product water shall be tested periodically to
verify that the system is performing properly. Test­ing can be accomplished by contacting the service
company that installed your R/O system or an au­thorized dealer. If a service company is not avail­able in your area a water sample may be sent to
AmeriFlow™ for a free TDS test of your R/O water.
Additionally a water quality monitor is available
for purchase from the manufacturer that will allow
the product water to be tested at home.

To send water samples for TDS testing to the man­ufacturer do the following. Using 2 clean contain­ers put approximately ½ cup of tap water in one

9

container and ½ cup of R/O product water in the
other container. Send both samples to the manu­facturer along with your contact information.

To order replacement filters or locate a source
in your area call the factory: AmeriFlow™ Water
Systems Inc. [phone].

STEP 10 FILTER CHANGING PROCEDURES

Sediment and Carbon: Turn Filter Pac/R/O mod-

ule ball valve to off position. Turn tank ball valve
off. Turn on R/O faucet to help de-pressurize
system. Unscrew filter bowls by turning count­er-clockwise. Remove old filters and discard.
Clean filter bowls if needed in warm, soapy wa­ter. Insert new filters into appropriate filter bowls.
Make sure O-ring at top of filter bowl is clean, lu­bricated and seated properly when tightening. If
changing the post filter, do so now following the
same procedure as the pre-filters. Follow Step 7:
System Start-Up Procedures. Check for leaks and
adjust as necessary.

R/O Membrane: Turn R/O tank and water supply
off. Turn on R/O faucet to help de-pressurize sys­tem. Disconnect white tube going into membrane
housing. Unscrew end cap of membrane hous­ing. Have a towel and a bucket handy because
some water will pour out. Pull out old membrane
and clean membrane housing if necessary with
warm, soapy water. Insert new membrane in the
same direction as old membrane. Push firmly up
to properly seat R/O membrane. Replace end cap
and reconnect white tube to membrane housing.
Follow Step 7: System Start-Up Procedures. Sys­tem should be sanitized each time the membrane
is changed. (See Recommended Sanitizing Pro­cedures). Test TDS (Total Dissolved Solids) rejec­tion rates and be sure the rates are over 75%. A
TDS monitor is optional on some models and in­cluded on others. If your unit did not come with
a monitor, you can order one or seek advice from
a local water treatment service company. A new

membrane should perform between 90-98% TDS
removal. Check for leaks and adjust as necessary.

STEP 11 RECOMMENDED SANITIZING
PROCEDURE

The manufacturer recommends having your sys­tem professionally sanitized once a year. The best
time to sanitize is when changing all the filters
and/or when changing the membrane.

1. Drain all water from R/O tank by turning on
R/O faucet until water stops flowing. Follow
Filter Changing Procedures (assuring ball
valve on tank and Filter Pac/R/O module
are in off position). Remove old pre-filters
and membrane from housings. Remove the
post-filter from the filter bowl canister.

2. Carefully put 2 capfuls of household bleach
into the empty filter bowl canisters. Re-install
filter bowls without filters. CAUTION: Be care­ful not to splash bleach on hands or surfaces.

3. Turn water supply on (open ball valve on
tank and R/O module) and let system fill for 4
minutes with tap water. Shut system off. Turn
R/O faucet on until water comes out and then
shut it off.

4. Let entire system sit for about 30 minutes
to sanitize. Then turn on R/O faucet and let
system drain until empty. Turn off water sup­ply valves and empty water in filter bowls.
Re-install filter bowls. Turn the water supply
on again. Turn off faucet and let system re­fill with tap water as before. Drain again. In­stall new filters following the Step 10: Filter
Change Procedures. Follow Step 7: System
Start-Up Procedures.

ter quality. Test TDS rejection rates at least ev­ery 6 months. Changing filters is important for
continuous good water quality. Filters need to
be replaced at recommended intervals as old fil­ters may retain a considerable amount of debris
and contaminants. Failure to change filters, use
of lower quality filters, or improper sanitization
can dramatically reduce membrane life and wa­ter quality. DO NOT WAIT UNTIL YOUR WA-
TER TASTES BAD TO REPLACE YOUR FILTERS.
Remember most contaminants do not have a foul
taste except in extreme quantities. Testing the

check valve, flow restrictor, incoming water pres­sure, water hardness, and TDS levels periodically
are important to help extend membrane life and
overall water quality. Your local water profession­al can easily perform these tests. Failure to follow
proper maintenance instructions, use of filters
or parts other than those recommended by the
manufacturer, or use of an unauthorized service
agent may void your warranty.
