1.1 WHAT IS OZONE?

Ozone is a form of naturally occurring oxygen possessing three atoms of oxygen per molecule
instead of the normal two-atom oxygen molecule. Created by either lightning or ultraviolet
radiation, ozone is commonly found in our atmosphere. The “ozone layer” protects us from
the sun’s radiation. The “fresh air” smell after a thunderstorm is due to lightning generated
ozone.

Ozone has a relatively short life span before it reverts back to oxygen. While active, ozone is
52% stronger and 3,125 times faster (in water) than chlorine as a disinfectant. Since it is
much more effective than chlorine in destroying water-borne contaminants, ozone has
become the preferred method of water treatment for over 4,000 large cities worldwide.

Ozone is recognized by the U.S. Environmental Protection Agency as a viable water treatment
alternative to chlorine, and the FDA has added ozone to its list of disinfectants approved
“Generally Recognized as Safe.” Ozone is the most powerful and rapid acting oxidizer
disinfectant produced, and will oxidize all bacteria, endotoxin and biofilms it comes in contact
within medical piping and water systems.

98-0121 Revision C

1.2 THE TECHNOLOGY

The AmeriWater Ozone Disinfection System uses a high technology corona discharge
process for producing ozone. Ozone is manufactured by drawing oxygen (O2) into the ozone
generator and exposing it to multiple high voltage electrical discharges. This causes a
percentage of the oxygen molecules to dissociate and reassemble as ozone (O3). The ozone
is drawn into the water by a venturi injector / mixer allowing the ozone to be injected into the
water under a vacuum condition. A pressure differential of at least 15 PSI (Pound per Square
Inch) must be maintained across the venturi injector. This pressure causes a vacuum that is
measured on the vacuum gauge. The gauge should read between –3” and –8” Hg when the
system is in normal operation. The Ozone Disinfection System provides microbial reduction
by a combination of disinfection by ozone and by physical removal by draining, flushing, and
refilling the systems with fresh, purified water.

1.3 INDICATIONS FOR USE

The AmeriWater Ozone Disinfection System is an optional accessory for the AmeriWater
Bicarb Solution Mix and Distribution System (SDS) cleared for market under K051031 and the
AmeriWater Water Purification System (WPS) for Hemodialysis cleared for market under
K991519. It is intended for use in hospitals and dialysis clinics for the disinfection of the
AmeriWater SDS and WPS system. The disinfection process is completed during off-hours
when the SDS or WPS are not being used for patient treatment. The AmeriWater Ozone
Disinfection System provides dissolved aqueous ozone concentrations of at least 0.5 ppm
with a contact time of at least 30 minutes for disinfection of the WPS and SDS systems (the
entire disinfection process takes approximately 2 hours to complete and longer contact times
may be necessary based on microbial loads). The Ozone Disinfection System is designed to
produce water with a microbial count of 50 CFU/ml.

1.5 HEALTH AND SAFETY

Ozone is a toxic gas above certain high concentrations, and an irritant at lower
concentrations. The Occupational Safety and Health Administration (OSHA) regulations state
that an individual must not be exposed to a concentration of ozone gas higher than:

1) 0.10 PPM (Parts Per Million) by volume over an 8-hour period.

2) 0.20 PPM by volume over a 10-minute period.

*See Ozone Badge information in Section 9.

The AMERIWATER OZONE DISINFECTION SYSTEM uses a gas off tank to contain any
ozone gas not dissolved in the water and an ozone gas destruct device to limit the ozone
exposure in the area of use. Ozone has a very short half-life and will decompose to oxygen in
less than 5 hours. The human nose can detect the ozone odor at .02 PPM, which is 5 times
lower than the OSHA safe level.

Call 1-800-535-5585 for the ozone SDS sheet.

WARNING: Oxygen is a fire hazard. It is a highly active oxidizer as it

vigorously accelerates the burning of combustible materials. Do
not use oil, grease, cotton fibers or any other combustible material
on or near the Ozone or Oxygen Generator. Smoking, heat or any
open flame should be kept at a distance of not less than 5 feet from
any part of the system. It is STRONGLY recommended that only
individuals experienced in the safe handling of Oxygen be allowed
to operate this equipment.

AVERTISSEMENT: L'oxygène est un risque d'incendie. C'est un oxydant très actif car il

accélère vigoureusement la combustion des matières
combustibles. Ne pas utiliser d'huile, de graisse, de coton ou tout
autre matériau combustible sur ou près du générateur d'ozone ou
de l'oxygène. Fumer, la chaleur ou d'une flamme nue doit être
maintenue à une distance d'au moins 5 pieds de toute partie du
système. Il est fortement recommandé que seuls les individus
expérimentés dans la manipulation de l'oxygène être autorisés à

utiliser cet équipement.
WARNING: Connect power cord only to a properly grounded wall outlet.
AVERTISSEMENT: Branchez le cordon d'alimentation à une prise murale correctement

mise à la terre.

1.6 OZONE COMPATIBLE MATERIALS

Ozone is one of the strongest oxidizing agents currently available for water treatment, so great
care should be taken to ensure that all piping, valves, gaskets, and other materials used in the
water treatment system that will come in contact with ozone are resistant to the concentrations
of ozone present during disinfection. Just about all the materials except filter cartridges and
membranes used in the typical water system are acceptable.

Below is a list of materials that are compatible for ozone concentrations up to 6 PPM in water.

Piping: Gaskets & Seals:

304L Stainless Steel Kel-F 2800
316L Stainless Steel Kal-Rez
PTFE (Teflon) Chem-Rez
ETFE (Teflon) Gortex
ECTFE (Halar) Teflon tape
PVDF (Kynar) Hypalon
CPVC Schedule 80 Viton
PVC Schedule 80 Silicon
HDPE (Polyethylene) EPDM
PP (Polypropylene)

NOTE: Natural rubber and many plastic and synthetic rubbers cannot be used

as gaskets, seals, or o-rings in combination with ozone. Exposure to
ozone will cause these components to become brittle and crack.

REMARQUE: Le caoutchouc naturel et les caoutchoucs de nombreux plastiques et

synthétiques ne peuvent pas être utilisés comme joints d'étanchéité,
joints toriques ou en combinaison avec de l'ozone. L'exposition à l'ozone
provoque ces composants deviennent fragiles et le crack.

SECTION 3, RPC E-Z Chek® Ozone Test Strips

3.1 TESTING

Procedure to detect (test for) ozone levels between 0 ppm and 0.4 ppm:

1) Dip one test strip into a 50mL (about 2 oz.) water sample with constant, gentle back-and-

forth motion for 10 seconds (25-28 strokes).

2) Remove the strip, shake once, briskly, to remove excess water and wait 20 seconds.

3) Then, view through the aperture pad to match with the closest color on the bottle label.

4) Complete color matching within 30 seconds.
Note: For better color matching view the aperture against a white surface. A suggestion is to

fold the white plastic handle of the test strip under the aperture so that it produces a
white viewing background (blocks distractions from behind aperture).

Procedure to detect (test for) ozone levels between 0.5 ppm and 1.0 ppm:

1) Collect a 25 ml sample of the ozonated water to be tested.

2) Dilute and mix the 25 ml ozonated test sample with 25 ml of known ozone-free water

(distilled, D.I., or RO).

3) Immediately test the resulting solution using the K100-0111 ozone test strip and the

instructions for use in 1-4 above.

4) Compare the color development on the test strip to the color blocks on the ozone test strip

bottle.

5) Note the test result and multiply it times two (compensates for 50% dilution) to determine

the actual ozone level.

For example: If the ozone level in the initial 25 ml ozonated sample was actually 0.6 ppm, then

the test value after 50% dilution should be 0.3 ppm. Record the actual ozone
value as 0.6 ppm.

3.2 WARNINGS AND CAUTION

 Do not touch the indicator pads.
 Keep all unused test strips in the original bottle.
 Replace cap immediately/tightly after removing a strip.

11

98-0121 Revision C

 Do not use test strips from an opened or unopened bottle after expiration date printed on

the bottle label.

 Do not allow the test strip to come in contact with liquids or with work surfaces that may

contaminate the strip.

 Do not leave test strips in areas exposed to vapors of any type.

3.3 STORAGE AND HANDLING

KEEP THE CAP ON TIGHT BETWEEN USES.
REPLACE CAP IMMEDIATELY AFTER REMOVING STRIP.

 Store the test strips at temperatures between 15°-30°C (59°-86°F).
 The lot number and expiration date are printed on each bottle. Do not use a test strip after

the expiration date.

 Do not touch the indicator pad.
 Do not allow the test strip to come in contact with liquids or with work surfaces that may be

contaminated with potentially interfering substances.

 Do not leave test strips in areas exposed to chlorine vapors or other oxidizing vapors.

SECTION 4, INSTALLATION & OPERATION

4.1 GENERAL OVERVIEW

WARNING: Do not turn the ozone generator on until the water flow has been

established.

AVERTISSEMENT: Ne pas tourner le générateur d'ozone jusqu'à ce que le débit

d'eau a été mis en place.

The flow path in the AmeriWater Ozone Disinfection System is illustrated in Section 2.2. The
water to be disinfected is pumped into the AmeriWater Ozone Disinfection System by the
water distribution pump or the bicarb system pump(s). The water flows through the feed flow
meter and into the venturi injector, which draws the oxygen from the oxygen valve through the
flow meter into the generator creating ozone. The ozone is then mixed in the water flow. The
ozone rich water enters the gas off tank to remove any excess, undissolved ozone gas and
then is directed into the water system to be disinfected. The ozone gas collected in the gas
off tank is vented automatically to the ozone gas destruct chamber and destroyed.

The driving force of the AmeriWater Ozone Disinfection System are the pump(s) on the bicarb
system or the distribution pump(s) on the water loop. A valve arrangement has to be installed
after the water treatment system distribution pump(s) and/or the bicarb system pump(s) to
divert the flow into the AmeriWater Ozone Disinfection System and back to the bicarb system
or the storage tank.

Figure 4A

13

98-0121 Revision C

In the illustration Figure 4A, Valve A is throttled and Valves B and C are open. (Note: Valve A
is only closed enough to divert the loop water through the ozone system.) On newer storage
tank systems, this 3 valve arrangement has been replaced with quick disconnect fittings.

Once the flow through the AmeriWater Ozone Disinfection System is established, the “Feed
Flowmeter” on the unit should read from 3.5 to 5GPM. The amount of pressure supplied by
the pump causes this variation in flow. If the “Feed Flow” is below 3 GPM the venturi injector
may not draw the oxygen through the generator properly, throttle valve A until the flow is
above 3 GPM. It is also necessary to have a differential pressure across the venturi injector to
create a vacuum. The vacuum gauge should read between -3 and -8 in of Hg.

Once the water flow has been established, a vacuum will draw the oxygen into the ozone
generator and ozone will be created. The ozone generator has a vacuum switch and will not
operate without a minimum of -3” of vacuum from the venturi injector indicated on the vacuum
gauge.

The gas off tank is in the flow path after the venturi injector. The water-ozone mix enters the
bottom of the tank and exits at the bottom of the tank. The excess ozone will gas off and be
vented to the destruct chamber to be converted to oxygen.

When ozone is injected into the water, Ameriwater recommends a reading of (0.5 ppm or
mg/l) or greater for more than 30 minutes to thoroughly disinfect a system. Be aware that the
water being disinfected may contain bacteria and endotoxin, and the piping may contain
biofilm all of which consume the ozone. It is important to verify the ozone concentration at the
end of the loop, not at the feed sample port, with a RPC Ozone in Water Test Strip (K100-

0111) before starting the 30-minute dwell time.
Due to the killing of the bacteria, endotoxin will be present. You must dump the tank, refill,

flush the loop and dump the tank again prior to use.

Helpful Hints

 Rapid intermittent stopping and starting of the ozone generator must be avoided to

prevent damage to the generator.

 After stopping the ozone generator, do not restart for 1 minute.
 Input voltage to the ozone generator should never exceed 125 Volt AC 60 Hz.

(The AmeriWater Ozone Disinfection System operates on 115 Volt AC 60Hz).

 Always use clean, dry, oxygen.
 Do not allow water to enter ozone generator. If a leak is detected inside the ozone

disinfection system, turn off the system, unplug the power cord from the receptacle and
repair the leak prior to restarting.

 When adjusting the oxygen flow to the Ozone Disinfection system higher flow creates

lower vacuum and lower flow creates more vacuum.

98-0121 Revision C

4.2 “OLD” WATER TREATMENT SYSTEM DISINFECTION PROCEDURE

WARNING: Verify that all patient treatments have been terminated prior to

disinfection with ozone.
AVERTISSEMENT: Assurez-vous que tous les traitements des patients ont été résiliés

avant la désinfection à l'ozone.

NOTE: When the red on/off switch light is lit, the ozone generator is

producing ozone.

REMARQUE: Lorsque le rouge lumineux marche / arrêt interrupteur est allumé, le

générateur d'ozone est la production d'ozone.

1. Remove the loop filter cartridges and store in plastic. (If a cross flow ultra-filter is used

remove the membranes from the housings or bypass the ultra-filter).

2. Disconnect the DI exchange tanks and place a latex glove over the fittings on the

tanks. Jumper the hoses together by connecting the male connectors to the female
connectors or by using jumpers. Close the valves on the inlet and discharge side of the
DI Header and open the bypass valve. Exposing DI tanks to ozone may cause damage
to the tanks and destruction of the resin beads.

3. Connect the ozone inlet hose to VALVE B, on the ozone bypass (see Figure 4B).

Connect the ozone outlet hose to VALVE C, on the storage tank. The quick connect
fittings are gender-oriented to prevent incorrect connections.

4. Open VALVE B on the loop and VALVE C on the storage tank. Throttle VALVE A on

the loop (see Figure 4B) to force water through the ozone system. Turn on the
distribution pump. (If the water system has dual distribution pumps, use only one of the
pumps at this time.) The feed flow should be between 3.5-5 GPM.

5. Plug the power cord for the AmeriWater Ozone Disinfection System into a 115 V,

properly grounded power outlet.

6. Connect the oxygen supply to the oxygen connection on the front of the ozone

disinfection system and adjust to 2-4L.

7. Turn on the oxygen flow meter valve (2-5 SCFH). Verify that the vacuum gauge on the

front of the cabinet is above –3” Hg (the operating range is –3” to –6” Hg). The ozone
generator will not operate if the vacuum is less than –3” Hg. The vacuum is adjusted
by providing more or less oxygen flow. Less oxygen flow produces more vacuum.
More oxygen flow decreases the vacuum.

8. Turn the ozone generator power switch ON (see Figure 1 section 2.2).

15

98-0121 Revision C

9. If the ON / OFF switch is illuminated, ozone is now being supplied to the system being

disinfected. Monitor the FEED FLOWMETER (3.5-5 GPM) and the VACUUM GAUGE
(-3” to –6” Hg) to verify they are in range.

10. Run the unit until the water from the sample port of the system has a reading of no less

than 0.5 ppm or mg/l. Use the RPC Ozone Test Strip to obtain this reading.

11. Continue running the system for 30 minutes at a minimum of 0.5 ppm or mg/l to build

the ozone level in the storage tank.

12. Throttle VALVE A to allow ozonated water from the storage tank to the loop. (Note: on

some systems, VALVE A may not need to be throttled at all.) Verify flow and pressure
on the loop.

13. If the water system has dual distribution pumps, use the opposite pump at this time.

14. Continue running the ozone system until ozone is detected at the end of the loop at a

level no less than 0.5 ppm or mg/l. DO NOT USE THE FEED SAMPLE PORT TO
VERIFY THIS. This level must be maintained for 30 minutes to completely disinfect the
system. If the water system has bacteria, endotoxin, or biofilm the ozone will be
consumed, so it may require several minutes to achieve the 0.5 ppm or mg/l level at the
end of the loop.

15. All points of use must be opened and tested with the RPC Ozone Test Strips to verify

that ozone is present at a level no less than 0.5 ppm or mg/l.

16. Turn off and disconnect the oxygen supply from the ozone disinfection system.

17. Turn the ozone generator power switch OFF (see Figure 1) and unplug the ozone

disinfection system from the power outlet.

18. Turn off the distribution pump and close VALVE B and VALVE C, and FULLY open

VALVE A. Let the system dwell for 15-30 minutes before turning the distribution pump
back on.

19. Empty the tank to remove any endotoxin created by the destruction of the bacteria.

20. Refill the tank with RO water and flush the distribution loop. Empty the tank again.

21. Return the water distribution system to normal operation, reconnect the DI exchange

tanks and replace the loop filter cartridges. The residual ozone will not affect these
components.

16

98-0121 Revision C

WARNING: The water distribution system contains ozone, which can be left in

the system if dialysis treatments are not scheduled within 3 hours

of completing disinfection. In the event that the water distribution

system will be used for dialysis less than 3 hours after disinfection,

dump the storage tank to drain and refill the tank with RO water.

Test the end of loop, ppm or mg/l level, when the storage tank is

full. If the ppm or mg/l level is above 0.0 ppm or mg/l, dump the

storage tank to drain and refill the tank until the residual level is not

above 0.0 ppm or mg/l.
AVERTISSEMENT: Le système de distribution d'eau contient de l'ozone, qui peut être

laissé dans le système si les traitements de dialyse ne sont pas

prévues dans les 3 heures suivant la fin de la désinfection. Dans le

cas où le système de distribution de l'eau sera utilisée pour la

dialyse à moins de 3 heures après la désinfection, vider le réservoir

de stockage pour vider et remplir le réservoir avec de l'eau

osmosée. Tester la fin de la boucle, ppm ou mg / l niveau, lorsque

le réservoir est plein. Si l'ppm ou mg / l niveau est au-dessus 0,0

ppm ou mg / l, vider le réservoir de stockage pour vider et remplir le

réservoir jusqu'à ce que le niveau résiduel ne dépasse pas 0,0 ppm

ou mg / l.

REMARQUE: Lorsque le rouge lumineux marche / arrêt interrupteur est allumé, le

générateur d'ozone est la production d'ozone.

1. Remove the loop filter cartridges and store in plastic. (If a cross flow ultra-filter is used

remove the membranes from the housings or bypass the ultra-filter).

2. Disconnect the DI exchange tanks and place a latex glove over the fittings on the

tanks. Jumper the hoses together by connecting the male connectors to the female
connectors or by using jumpers. Close the valves on the inlet and discharge side of the
DI Header and open the bypass valve. Exposing DI tanks to ozone may cause
damage to the tanks and destruction of the resin beads.

3. Connect the Inlet and outlet quick disconnect fittings to their appropriate ozone hose.

Hoses are gender oriented to prevent incorrect connections.

4. Connect the ozone inlet hose to the quick connect fitting on the pump discharge (See

Figure 4C). Connect the ozone outlet hose to the quick connect fitting on the storage
tank. The quick connect fittings are gender-oriented to prevent incorrect connections.

4. Turn on the distribution pump. (If the water system has dual distribution pumps, use

only one of the pumps at this time.) The feed flow should be between 3.5-5 GPM.

5. Plug the power cord for the AmeriWater Ozone Disinfection System into a 115 V,

properly grounded power outlet.

6. Connect the oxygen supply to the oxygen connection on the front of the ozone

disinfection system and adjust to 2-4L.

7. Turn on the oxygen flow meter valve (2-5 SCFH). Verify that the vacuum gauge on the

front of the cabinet is above –3” Hg (the operating range is –3” to –6” Hg). The ozone
generator will not operate if the vacuum is less than –3” Hg. The vacuum is adjusted
by providing more or less oxygen flow. Less oxygen flow produces more vacuum.
More oxygen flow decreases the vacuum.

8. Turn the ozone generator power switch ON (see Figure 1 section 2.2).

19

98-0121 Revision C

9. If the ON / OFF switch is illuminated, ozone is now being supplied to the system being

disinfected. Monitor the FEED FLOWMETER (3.5-5 GPM) and the VACUUM GAUGE
(-3” to –6” Hg) to verify they are in range.

10. Run the unit until the water from the sample port of the system has a reading of no less

than 0.5 ppm or mg/l. Use the RPC Ozone Test Strip to obtain this reading.

11. Continue running the system for 30 minutes at a minimum of 0.5 ppm or mg/l to build

the ozone level in the storage tank.

12. If the water system has dual distribution pumps, use the opposite pump at this time.

13. Continue running the ozone system until ozone is detected at the end of the loop at a

level no less than 0.5 ppm or mg/l. DO NOT USE THE FEED SAMPLE PORT TO
VERIFY THIS. This level must be maintained for 30 minutes to completely disinfect the
system. If the water system has bacteria, endotoxin, or biofilm the ozone will be
consumed, so it may require several minutes to achieve the 0.5 ppm or mg/l level at the
end of the loop.

14. All points of use must be opened and tested with the RPC Ozone Test Strips to verify

that ozone is present at a level no less than 0.5 ppm or mg/l.

15. Turn off and disconnect the oxygen supply from the ozone disinfection system.

16. Turn the ozone generator power switch OFF (see Figure 1) and unplug the ozone

disinfection system from the power outlet.

17. Turn off the distribution pump. Let the system dwell for 15-30 minutes before turning

the distribution pump back on.

18. Empty the tank to remove any endotoxin created by the destruction of the bacteria.

19. Refill the tank with RO water and flush the distribution loop. Empty the tank again.

20. Return the water distribution system to normal operation, reconnect the DI exchange

tanks and replace the loop filter cartridges. The residual ozone will not affect these
components.

discovery of the defect. Each system for which a warranty claim is asserted shall, at the
request of AmeriWater, be returned freight prepaid with proof of purchase date to AmeriWater
at the expense of the purchaser. Any replacement parts shall be warranted as stated above
for the original one-year warranty.

This warranty does not extend to any generator or part if a defect or malfunction occurs from
misuse. Allowing water to enter the generator will cause damage not covered under
AmeriWater’s product Warranty. Feed gas must be clean, dry Air or Oxygen at –60º F dew
point for maximum Ozone production. Provide proper voltage to the generator (100-125 VAC
60 Hz). Improper voltage causes damage not covered under the AmeriWater Product
Warranty. Locate the generator in a well-ventilated area that is protected from the weather
elements and remains between 40º F and 100º F to prevent damage not covered under the
AmeriWater Product Warranty.

There are no warranties on the AmeriWater Ozone Disinfection System beyond those
specifically described above. All implied warranties, including any implied warranty of
merchantability or of fitness for a particular purpose are disclaimed to the extent they might
extend beyond the above periods. The sole obligation of the manufacturer under these
warranties is to replace or repair the component or part which proves to be defective within
the specified time period, and the manufacturer is not liable for consequential or incidental
damages. No dealer, agent, representative, or other person is authorized to extend or expand
the warranties expressly described above.

Some states do not allow limitations on how long an implied warranty lasts or exclusions or
limitations of incidental or consequential damage, so the limitations and exclusions in the
warranty may not apply to you. This warranty gives you specific legal rights, and you may
also have other rights, which vary from state to state.

WARNING

This product can expose you to chemicals such as vinyl chloride (used in the production of
PVC) or Nickel (used in the production of stainless steel), that are known to the State of
California to cause cancer. For more information go to www.P65Warnings.ca.gov.

Dear Valued Customer,
California Proposition 65 (Prop 65) is the Safe Water and Toxic Enforcement Act of 1986. The

State of California began enforcing amendments to California Prop 65 at the end of August 2018.
Prop 65 requires manufacturers to provide a clear and reasonable warning to residents of
California about chemicals used in products that they purchase that are included on the Prop 65
Chemical List. The chemicals included on the list are chemicals that are known to the State of
California to cause cancer, birth defects, or other reproductive harm. One such chemical is Vinyl
Chloride, a compound used to produce Polyvinyl Chloride (PVC). The AmeriWater system you
have purchased may contain PVC or stainless steel parts.
While warnings are only required in the State of California, AmeriWater has initiated the use of
Prop 65 labeling for all products to ensure compliance with California regulations. Please note that
the above warning does not necessarily mean that the product that you have purchased is unsafe.
Products that have been cleared for market by FDA have been determined to be safe and effective
by the United States Food and Drug Administration. The warning is simply a requirement by the
State of California. If you wish to obtain additional information, please visit: p65warnings.ca.gov.
You may also contact your AmeriWater representative if you have any questions.

Thank you for your understanding and we look forward to continuing to serve you.
