SECTION 2, TECHNICAL INFORMATION
2.1 THEORY OF OPERATION
RO:
The process of osmosis can be reversed by placing pressure upon the feed water side
(concentrated solution side) of the membrane. Water will be forced through the membrane
barrier to yield water that is purer on the lower pressure side of the membrane than on the
more concentrated solution side (higher pressure side) of the membrane. The feed water will
become more “concentrated,” and will be discharged through the reject port known as “reject
water” or “concentrate”.
Hence, the liberation of purer water from its solutions is caused by the reversal of the osmotic
pressure; the operation is termed “Reverse Osmosis”. Reverse Osmosis is commonly
referred to as “RO”.
DI Polisher:
This system is designed to polish the RO product water in order to provide purified water
used in laboratory applications. The facility’s tap water first passes through the RO, then
enters the first deionizer column (worker) where the deionizer resin removes chemical
contaminants from the water through an ion exchange process. The water then passes into
the “polisher” column. As water leaves the polisher, the purified water passes through a
200,000-Ohm resistivity monitor with alarm and on to the storage tank.
Storage Tank:
The storage tank is equipped with 2 float switches, one which will turn the reverse osmosis
unit off when the water reaches the predetermined cutoff point and another to turn the RO on
when the tank is drained to the appropriate level float. The distribution pump on the storage
tank will cycle whenever there is a pressure drop detected. A flow switch has been wired into
the pump to act as a kill switch to prevent the pump from operating when there is no water
flow.

SECTION 4, INSTALLATION
CAUTION: Local plumbing and electrical codes must be observed.
4.1 RO INSTALLATION
1. The electrical source must be single phase, 3-conductor type provided with a hospital
grade receptacle and a ground fault interrupter (GFI) at 115V, 15amp, and 60Hz. The
proper polarity and ground integrity must be initially checked and thereafter maintained.
Failure to do so may result in electrical shock to the operator. It is suggested that the
RO be placed on an electrical supply with emergency backup. The pump for the R0
must be plugged into a dedicated 220V/60Hz/15A outlet.
2. The RO controller must only be plugged directly into a GFI receptacle. It must not be
plugged into an extension cord or power strip that could cause low amperage.
To avoid electrical shock, always unplug the RO system before opening the face
of the electrical controller.
3. Incoming water should be between 41° F and 90° F (5° C and 33° C). It is not
recommended to use water at temperatures below 41° F (5° C) as it will reduce
membrane performance significantly. Use only the cold water supply unless using an
automatic blending valve to get 77° F (25° C) water. Never use water warmer than 90°
F (33° C).
98-2005 Rev. G
Page 21
18
4. Water with silt density index (SDI) above 5 SDI will foul the membrane.
5. The RO system is equipped with a pretreatment system to remove chlorine. It is
important to test for chlorine at the CHLORINE SAMPLE PORT periodically. Chlorine
will deteriorate the membrane and cause system failure. It is recommended to use a
Chlorine test strip.
6. Incoming tap water pH should be within EPA National Secondary Drinking Water
Regulations of 6.5 - 8.5. Incoming tap water with pH higher or lower than the
regulation will cause higher conductivity in the product water. If the water changes
drastically, the membrane will be harder to clean. Periodically check the pH of the
incoming tap water to verify that it is within the specified range (IBT pH Water Test
Strips P/N 97PH20901).
7. Always maintain water flow and pressure to avoid damage to the pump.
8. Minimum feed pressure is 20 PSI @ 6 GPM (while the RO is in operation, with flow).
Maximum feed pressure is 50 PSI.
9. Lock the two front casters so that the device will remain stationary during startup.
10. Remove the caps from the PRODUCT WATER, REJECT WATER TO DRAIN, and
INCOMING TAP WATER fittings on the side of the RO.
11. Connect the INCOMING TAP WATER, PRODUCT WATER and REJECT WATER TO
DRAIN hoses to the appropriate fittings on the RO. All hoses should run to the rear of
the device. This will allow you to move the RO forward to access the rear panel.
12. If the supply water is not softened, you will need to install the PT 401 pump by
engaging fitting on the PT 401 pump with the 5 terminal side entry hood on the side of
the RO.
13. Plug the power cord into a dedicated 115-volt, 15-amp GFI receptacle.
14. Plug the pump power cord into a 220-volt, 15-amp receptacle.
4.2 DI POLISHER
1. Locate the DI Polisher to the right of the RO, just before the storage tank.
2. Route the product water hose from the RO behind the RO to connect to the DI Polisher
hose inlet after disinfection.
3. Plug the power cord into a 115-volt outlet.
98-2005 Rev. G
Page 22

4.3 STORAGE TANK
1. Locate the storage tank on a firm, level foundation. For seismic requirements, drill (4)
5/8” diameter holes into the concrete through the mounting holes in the storage tank
feet a minimum of 4” deep. Install (4) 5/8” diameter, HILTI KB-TZ Expansion anchors
through the 4 holes on the pads to anchor into the ground. A minimum of 4 threads for
each anchor must be below the concrete prior to application of 60 ft-lbs of torque.
2. Connect the DI Polisher outlet hose to the storage tank’s inlet.
3. Connect the discharge from the pump to the distribution piping.
4. Run the float – switch quick disconnect to the RO and lock in place.
5. Prime the pump by filling the tank with water and opening the valve into to the pump’s
inlet. Loosen the priming plug on the pump to allow the air to escape. Once water
starts to escape, re-tighten the priming plug.
6. Plug the pump directly into a dedicated 220-volt, 15-amp receptacle.

SECTION 5, SYSTEM START-UP
WARNING: This Reverse Osmosis System (RO) contains a preservative solution to
prevent microbiological growth and freezing. Discard all product water for
at least two hours of operation before placing the RO in service.
1. Connect the RO INCOMING TAP WATER hose to the potable cold water supply using
the Incoming Tap Water hose and fittings supplied. If blending both warm and cold
water to improve product flow rate, do not exceed 90° F (33° C).
2. The REJECT WATER TO DRAIN hose coming out of the RO is for reject water. The
water from this hose will go down the sink or drain. Leave at least a 2" air gap between
the hose and the drain to prevent contamination or siphoning.
3. The PRODUCT WATER hose should also be secured to the sink or drain.
4. Relieve the pressure from the system by opening the CHLORINE sample port.
5. Open the rear access cover and turn the CIP SWITCH to off.
6. Verify that the carbon cartridges are installed in the filter bowls.
7. Close the CHLORINE sample port and turn on the potable cold water supply to the RO.
Allow the membranes to completely fill with water.
8. Turn on the RO and turn the reject flow control knob counter clockwise to allow the
device to run in full flush for 15 minutes.
NOTE: The RO conductivity alarm may sound, which is normal when it is in FLUSH.
Press the ALARM SILENCE key on the RO controller to silence the alarm. The
alarm will restart after a 3 minute delay.
9. After flushing for 15 minutes, adjust the reject flow control knob so that there is an
equal amount of product and reject water passing through their respective flow meters.
10. Run the product water to drain for at least 2 HOURS to remove the preservative from
the system.
11. Verify that the PRODUCT GPM FLOWMETER indicates at least 2.00 GPM for a RO3
and 2.50 GPM for a RO4.
12. Refer to the Operation Log in Section 7.0 MONITORING. Complete the log; making
sure that the system is operating within all the required ranges.
WARNING: Do not use the RO until all specifications are met.
13. When the log shows that all start-up conditions are met, the system is now ready for
use. Press the POWER key (the display will show STANDBY). Connect the
PRODUCT WATER hose to the DI Polisher inlet.

slotted screw driver in the pry notch located in
the top of each upper plate. Open the drain
valve at the bottom of each column.
b) Remove the resin pack from the shipping box
and open the tied end of the plastic sleeve.
DO NOT remove the resin pack from the plastic
sleeve at this time.
c) Stretch the resin pack over your arm
to elongate the pack, and feed it into
the column allowing the pack to slide
out of the plastic sleeve. Save the
plastic bag for future exchange.
d) Verify that the O-ring is clean and in
place and replace the cover plates.
Tighten the black knobs evenly by
turning the knobs at opposite
corners at the same time. Repeat
for the other two corners.
CAUTION: Failure to tighten the knobs completely may cause the cover plate to
separate from the system when pressurized.
e) Close the drain valve at the bottom of the column.
AIR VENT
f) Repeat steps a. through e. for each of the columns.
15. Open the air vents located on the top of the cover plates and
turn on the water supply and the RO. Tighten the air vents
closed when water begins to escape through the vents.
16. Ensure that the DI Polisher quality light is plugged into a GFI
receptacle.
17. When the resin is changed, the light may indicate red
initially, but should switch to green, indicating good quality.
18. Lock the casters on the DI Polisher.
19. Verify that the distribution pump is plugged into a 220V/60Hz/15A dedicated outlet.

control panel. This is located on top of the pump, under the
storage tank.
5.1 PT401 PRIMING PROCEDURE
AmeriWater RO products featuring the PT401 antiscalant system are equipped with a priming
valve. The following procedure should be followed during the initial start up of the RO system,
and whenever the PT401 pump loses its prime:
1. Verify that the RO is on and running.
2. Be sure the injection pump’s suction line is immersed in solution in the PT401
container.
3. Press the ON key to turn on the PT401 injection pump.
4. Press the “DOWN” key to cycle the STROKE RATE to approximately 360.
5. Remove the lid form the container and verify that there is discharge of PT401.
6. Close the adjustment knob completely by turning clockwise until the knob stops,
making sure there is no liquid flow out of the air bleed tubing.
If the pump does not prime, repeat the foregoing
steps.
Once the pump has been primed, and is pumping the
chemical through the head into the water stream,
adjust the stroke rate to “10”.
At the stroke rate of 10, the PT401 injection pump will
put about 300 milliliters (approximately 10 liquid
ounces) per hour into the incoming water stream.
Repeat these steps as necessary when the system is
started after sitting for extended periods of time or the
PT401 Bottle is empty and air has drawn into the
pump. The priming may not take as long as the initial
time.
WARNING: Overdosing PT401 will adversely affect (blind) the membrane causing a
decrease and/or loss of permeate flow.
WARNING: If softened water is supplied, turn off the PT401 system by depressing the
on/off button on the chemical feed pump and emptying the PT401 jug.

HARDNESS (Grains Per Gallon)
STROKE SETTINGS
The amount of PT401 in the container should be checked weekly. When it is less than half
full, you should add more PT401.
Remove the cap from the PT401 Container. It is not necessary to remove the rubber stopper
with the hose; this will break the prime of the PT401 pump. Refill the container with new
PT401 purchased from AmeriWater (P/N 95810125, sold in (4) 1 gallon containers). Close
the container with the cap. If the PT401 Container is run dry, follow the priming procedures
above.
5.3 PT401 ANTISCALANT SETTINGS
The digital readout on the PT401 injection pump can be adjusted from 0 to 360 strokes per
minute. Based on the hardness of the feed water, the following stroke settings are
recommended:
1-6 GPG 9
7-20 GPG 11
21-40 GPG 13
For water with hardness greater than 40 GPG, contact AmeriWater for consultation

SECTION 6, OPERATION
6.1 OPERATION
Once the system has been started, the RO will continue to make water until the high-level
float switch is tripped on the storage tank. At this point, the RO will be placed into standby
(tank full) until the low-level float switch is tripped.
Once the low level float is tripped, the RO will re-initialize and begin to produce water again.
In the event that the conductivity is above the pre-determined set-point, an alarm will sound.
The storage tank will still operate as normal.
6.2 BYPASS PROCEDURE
1. Turn off the POWER to the RO and Distribution Pump.
2. Shut off the water supply to the system.
3. Remove the RO water inlet hose from the source.
4. Retrieve the bypass hose and install to the incoming water supply.
5. Connect the CPC connector into the fitting just after the pump on the storage tank.
6. Turn on the water to begin bypass operation.

SECTION 8, MAINTENANCE
WARNING: If any component of the water treatment system is changed or replaced,
the user should conduct appropriate tests to ensure that the revised
system meets all standards to which it was initially tested.
WARNING: Maintenance shall be performed by qualified personnel only.
1. AmeriWater has provided an Operation Log for the RO. The recorded information may
be useful in troubleshooting problems encountered with the system.
2. The DI resin, membrane and carbon cartridges are non-durable components and will
need to be exchanged periodically.
8.1 RO NORMAL MAINTENANCE ITEMS
Preparation
1. Turn off the RO and remove from the power source.
2. Turn off the incoming tap water supply.
3. Place a container under the CHLORINE TEST PORT. Slowly open the sample port to
relieve the pressure and let the water drain.
4. Remove the rear cover.
To Exchange the Carbon Block Filters:
1. Use the filter wrench to unscrew the filter housing and discard the used filter(s).
2. Partially unwrap the plastic from a brand new filter. Holding the end covered with
plastic, place the new filter in the housing. Discard the plastic after installation.
3. Screw the filter housing back on making sure the o-ring is in the groove and not
pinched. Hand-tighten, only.
To Exchange the Membrane:
1. Mark the location on each compression fitting prior to loosening the nut.
2. Disconnect the fittings that secure the tubing to the sides of the membrane.
3. Remove the Unistrut clamp holding the membrane assembly.
4. Lift out the membrane assembly.
5. Loosen the nuts on the retaining clamp on the feed side to remove the cap and slide
old membrane out of the housing and discard.
98-2005 Rev. G
Page 30
27
6. Install the new membrane in the housing with the brine seal at the Inlet end of the
housing, and replace the cap and retaining clamp.
7. Connect the feed (brown) fittings at the bottom of the new membrane housing in the
same way the system was initially connected. Secure the new membrane assembly
into place, and connect the remaining fittings at top of membrane housing (Reject =
red, Product = blue, Inlet = Brown).
8. Reconnect compression fittings and tighten them to the initial locations. You may need
to go slightly beyond this mark to get a good seal. Please use caution when doing this
as excessive tightening will thin the wall section of the tubing, which may lead to leaks
or a break.
9. Re-install the membrane using the Unistrut clamps.
10. Repeat this for each membrane to be changed.
Rinse Out Cycle
WARNING: This Reverse Osmosis (RO) membrane contains a preservative solution to
prevent microbiological growth and freezing. Discard all product water for
at least two hours of operation before placing the RO back into service.
After the exchange is complete, it is important to put the RO through a rinsing out cycle to
flush the preservative out of the new membrane.
1. Put the PRODUCT WATER hose at a sink or drain.
2. Turn on the RO and turn the reject flow control knob counter clockwise to allow the
device to run in full flush for 2 hours. This will rinse the preservative out of the new
membrane.
3. Adjust the reject flow control knob so that there is an equal amount of product and
reject water passing through their respective flow meters and allow the RO to run until
the conductivity is below the set-point and no longer alarming. Turn off the RO.
98-2005 Rev. G
Page 31
28
4. Reconnect the PRODUCT WATER hose to the DI Polisher.
5. Turn on the RO. The rinse out cycle is now complete, and the RO is ready for use.
8.2 DI POLISHER RESIN PACK EXCHANGE
1. Turn off the water supply to the RO system.
2. Open the air vents located in the center of the cover plates.
3. Place a container under the Drain Valves located on the bottom plates of the system.
4. Open the valves and allow the water to drain into the container. The container may be
emptied at a drain.
5. Remove the cover plates by unscrewing the black knobs located at each corner of the
cover plates.
6. Pull the exhausted resin pack part of the way out of the column and lay it over the top
of the system.
NOTE: If the Drain Valve located on the bottom plate is not open, a vacuum will be
created making it difficult to remove the resin pack.
7. Slowly pull the exhausted pack over the side of the column while sliding it out of the
column and into the plastic sleeve that it was shipped in.
8. Remove the new resin pack from the shipping box and open the tied end of the plastic
sleeve.
9. Stretch the resin pack over your arm to elongate the pack.
10. Feed the pack into the column allowing it to slide out of the plastic sleeve. Save the
plastic sleeve for the return shipment of the resin pack at the next exchange.
11. Carefully wipe the O-rings and the grooves on the top plate and cover plate to remove
any debris from the surfaces that must seal together.
12. Replace the cover plates and tighten the knobs. To ensure proper tightening and a
good seal, hand-tighten the knobs in opposite corners simultaneously. Repeat for the
other two corners.
13. Turn on the water supply to the RO and remove trapped air by loosening the air vents
located in the center of the cover plates.
14. Tighten the air vents when water begins to escape through the vent. This ensures that
all of the air has been removed from the system and maximizes the life and efficiency
of the resin packs.

SECTION 11, OPTIONAL DISINFECTION
AmeriWater recommends that all HCRO systems should be disinfected at least annually. The
following sections will outline the disinfection steps for the RO, optional Silex deionizer and
Storage Tank.
11.1 RO DISINFECTION
1. Switch off the RO by pressing the POWER key (the display will show STANDBY).
2. Disconnect the RO PRODUCT WATER hose from the next point of use.
3. Place the PRODUCT WATER hose with the REJECT WATER TO DRAIN hose at a
sink. Secure PRODUCT WATER hose in place so that the entire length of the hose
will “flood” during disinfection.
4. Put on rubber gloves, apron, and goggles.
5. Unscrew the cap assembly of the PAA container.
6. Add 400 ml of 100% hydrogen peroxide/peroxyacetic acid disinfecting solution to the
PAA Container and fill with water to the red line. (You may use tap water or treated
water). Screw the cap assembly back on the PAA container.
CAUTION: Exposure to hydrogen peroxide/peroxyacetic acid (PAA) concentrate or
solution may cause severe chemical burns to skin or eyes. Additional
information regarding PAA is found in this section, on your PAA bottle, and
the Material Safety Data Sheet. Please read carefully before using.
98-2005 Rev. G
Page 36
33
7. Lightly shake or tilt the container to mix the solution for 10 seconds.
8. Connect the PAA tubing to the PAA connection on the front of the RO.
9. Turn the reject flow control knob counter clockwise to allow the RO to run in full flush.
10. Turn on the feed water supply to the RO.
11. Press and hold the LEFT ARROW key, and then, press the RIGHT ARROW key. This
will access the DISINFECT MODE. The controller display will show DISINFECT
ENABLED, and then the keys can be released.
12. Press and hold the ENTER key. Pressing and holding the ENTER key will turn on the
Disinfect Draw function and THE DISPLAY WILL READ DISINFECT ENABLED
DRAW. Continue to hold the ENTER key, until all of the PAA is drawn in.
13. If the PAA tubing begins to suck air, immediately release the ENTER key. Adjust the
reject flow control knob so that there is an equal amount of product and reject water
passing through their respective flow meters. Avoid extra time running because PAA
will be diluted.
CAUTION: Avoid sucking air when the container is near empty.
NOTE: The ENTER key must be held until the PAA is drawn container is
nearly drawn empty into the RO.
A. AVOID STOPPING AND STARTING THE DISINFECT FUNCTION WHICH
MAY CAUSE A THERMAL OVERLOAD OF THE RO PUMP. IF A THERMAL
OVERLOAD OCCURS, IT WILL AUTOMATICALLY RESET FROM 1 TO 5
MINUTES – WAIT UNTIL THE PUMP OVERLOAD RESETS TO RESUME
THE PAA DRAW.
B. RELEASING THE ENTER KEY MAY CAUSE THE SYSTEM TO LOSE ITS
PRIME PREVENTING ALL OF THE DISINFECTANT FROM BEING DRAWN
INTO THE MRO.
C. APPROXIMATELY ¼” OF THE SOLUTION WILL REMAIN IN THE BOTTOM
OF THE PLASTIC CONTAINER. THIS IS NORMAL AND MAY BE EMPTIED
DOWN THE DRAIN AFTER THE ENTIRE PROCESS IS COMPLETE.
14. At this point, the RO is filled with the PAA disinfecting solution. To ensure that this has
passed through the system, use a PAA test strip (Peracid Test Strips, P/N 97HP20401)
at the REJECT WATER TO DRAIN hose; the results should be at least 1% (500 ppm).
Use another PAA test strip (Peracid Test Strips, P/N 97HP20401) at the PRODUCT
WATER hose; the result here should be at least 0.5% (250 ppm).
NOTE: You may need to press the ENTER key to sample the flow being discharged
from the REJECT WATER TO DRAIN and PRODUCT WATER hoses. If the test
strip does not show PAA disinfecting solution at the specified levels in the
Reject Water and Product Water, press the ENTER key again to continue flow;
repeat the PAA test until both test positive (at the specified levels). If the test
strip still does not show the disinfecting solution at the required levels, repeat
disinfect draw procedure until the tests show positive at the required levels.
98-2005 Rev. G
Page 37

15. Allow the PAA mixture to soak in the RO for at least 60 minutes.
WARNING: Soaking longer than twelve hours may cause damage to the membranes.
16. After the soaking time has elapsed, turn on the RO by pressing the ALARM/SILENCE
RESET to restart the RO in the operating mode. Allow the machine to run at its current
setting for at least 15 minutes.
17. After rinsing the RO in the flush mode for 15 minutes (minimum), turn the reject flow
control knob clockwise to allow the RO to run in operation for another 15 minutes.
18. Adjust the reject flow control knob to full flush for 15 additional minutes, followed by 15
additional minutes in normal operation mode.
19. Continue rinsing for until the water from the PRODUCT WATER hose, REJECT
WATER TO DRAIN hose and the product sample port test negative for PAA.
WARNING: Continue rinsing and testing until both test strips show a negative result
(no color change) to ensure that there is less than 3 PPM of PAA in the
system. AmeriWater recommends using Renal Check PX Test Strips (P/N
97PX20501).
20. Disinfection is now complete. Press the POWER key to turn off the RO. The display
will show STANDBY.
11.2 A WORD ABOUT HYDROGEN PEROXIDE/PEROXYACETIC ACID
Do not use hydrogen peroxide/peroxyacetic acid concentrate (PAA) after the expiration date.
Using outdated PAA concentrate may cause incomplete disinfection.
PAA loses effectiveness if not kept out of direct sunlight and/or the cap is not tightly sealed.
Using ineffective disinfecting solution will cause incomplete disinfection.
Using less than the required volume of PAA will result with incomplete disinfection.
Disposal of Outdated Hydrogen Peroxide/Peroxyacetic Acid:
Supplies Needed - a sink with a supply of tap water
- rubber gloves, lab apron, and goggles
- a supply of paper towels
1. Put on rubber gloves, apron and goggles.
CAUTION: Exposure to PAA concentrate or solution can cause severe chemical burns
to skin or eyes.
2. Start a flow of cold tap water to dilute the PAA as it flows down the sink drain.
3. Slowly and carefully pour the disinfecting solution down the drain, taking care to avoid
spills, splashes, or breathing the vapors.
98-2005 Rev. G
Page 38
35
4. Rinse the emptied PAA container with tap water to remove all traces of the chemical.
Rinsing emptied containers is needed to protect waste handlers from accidental
exposure to the chemical.
5. Rinse the sink surfaces with tap water to remove residual disinfecting solution and to
flush the chemical from the sink traps.
6. Discard the emptied and rinsed container in a waste receptacle or set aside for
recycling.
7. Inspect the area for spilled or dripped disinfecting solution. Wipe up small spills with a
damp paper towel. Larger spills should be either flushed to drain with water or
removed with a water bucket and floor mop.
WARNING: Verify that there is no chlorine (bleach) in the water bucket or floor mop.
Chlorine (bleach) will cause a severe chemical reaction when it comes in
contact with hydrogen peroxide/peroxyacetic acid concentrate!
8. Rinse rubber gloves with tap water to remove any residues from handling.
9. Remove and return rubber gloves, apron, and goggles to their storage area.
11.3 SILEX DISINFECTION
1. Turn off the water supply to the Silex system and remove the discharge from the
storage tank.
2. Remove the resin packs from the system.
3. Pour 5 oz (150 mL) of PAA into each Silex column.
4. Close all drain valves and sample ports and open the air vents located in the center of
the top plates.
5. Turn on the water supply to the Silex and allow it to fill with water until the presence of
PAA can be detected at the outlet of the system. Verify the concentration of PAA at the
outlet using a high level concentration PAA test strip (P/N 9778339-000).
6. Turn off the water supply and allow the system to soak for 1 hour.
7. After the soak time, drain the water out of the system by placing a container under the
drain valves and opening the valves.
8. Close all valves and turn on the water supply to the system.
9. Direct the product water to a drain and allow system to flush until PAA is no longer
detected. (Use low-level PAA test strips, P/N 9778338-000, to test for residual PAA).
10. Drain the water out of the system by placing a container under the drain valves and
opening the valves.
98-2005 Rev. G
Page 39
36
11. Close all drain valves and sample ports and open the air vents located in the center of
the top plates.
12. Replace the resin packs and return system to service.
11.4 TANK DISINFECTION
Storage Tank Disinfection Procedure:
1. The storage tank can be disinfected using household bleach or a peracetic acid
disinfectant (PAA).
WARNING: Never allow Chlorine (bleach) to come into contact with PAA. Doing so
will cause a severe chemical reaction!
a. For a 55 gallon tank, fill to the RO shut-off level mark and add 1 quart of
household bleach or PAA.
b. For a 100 gallon tank, fill to the RO shut-off level mark and add 2 quarts of
household bleach or PAA.
c. For a 185 gallon tank, fill to the RO shut-off level mark and add 4 quarts of
household bleach or PAA.
NOTE: The values above will provide a 250 PPM concentration of disinfectant. If
desired, the disinfectant can be doubled to provide a stronger kill (500 PPM).
However, when this is done, the rinse-up time will be significantly longer.
2a. If your system is installed with a recirculation loop back to the storage tank, recirculate
the system for 30 minutes.
2b. If your system is a demand feed (where the pump only operates when your equipment
calls for water), connect the bypass hose to the quick disconnect and place the other
end of the bypass hose into the storage tank, close the distribution valve and allow the
pump to recirculate for 30 minutes.
3. After recirculation, drain the tank, fill with RO water, and recirculate for 5 minutes.
4. Drain the tank, refill and recirculate for 5 an additional minutes. Use a chlorine test
strip to verify the residual chlorine level or a PAA test strip to verify the residual PAA
level.
5. Repeat step 3 and 4 until the test strip indicates a residual level at or below 1.0 ppm.
