1. OBJECTIVE
The objective of the Clean In Place (CIP) system is to is to introduce high pH and
low pH membrane cleaners to the AmeriWater MRO system at low pressure and
high velocity. This action removes scale and organic contaminants from the
MRO membranes and improves system performance.
2. CHEMICALS REQUIRED
AmeriClean A (P/N 37-0004) low pH cleaner for removing inorganic scale and
metals from polyamide thin-film composite (3 lb (800 ml) of AmeriClean A powder
is required per membrane cleaning). AmeriClean A effectively removes the
following foulants:
•Calcium Carbonate Strontium Sulfate
•Calcium Sulfate Iron
•Barium Sulfate Metal Oxides
AmeriClean B (P/N 37-0005) high pH cleaner for removing acid insoluble
foulants from polyamide thin-film composite (3 lb (1,110 ml) of AmeriClean B
powder is required per membrane cleaning). AmeriClean B effectively removes
the following foulants:
•Silt Microbiological
•Colloids Acid Insolubles
•Organics Mucilaginous Material
WARNING: Wear appropriate eye and skin protection when handling the
membrane cleaning chemicals. The cleaners are high pH and low
pH chemicals that may cause severe chemical burns. Read the
MSDS for further information.
WARNING: Never allow AmeriClean A and AmeriClean B to mix! Mixing the
chemicals will cause an exothermic reaction which may result in
serious injury and/or damage to the equipment! Flush the system
thoroughly and verify that the pH of the reject water is neutral prior to
introducing another chemical!
WARNING: AmeriClean A and B membrane cleaners are for polyamide thin-film
membranes only and cannot be used on cellulose acetate
membranes.

3. SET UP
1. Remove the hoses and pump from the CIP tank (pump, hoses and fittings
are shipped inside the tank from the manufacturer).
2. Rinse the CIP tank and hoses with clean water to remove any debris or
contamination after un-packing or after the CIP system has been in
storage.
3. Install two of the long hoses into the upper ports on the tank by screwing
the 1” pipe thread adapter that is on the end of the hose into the pre-
mounted bulkhead fitting. Use two to three wraps of Teflon tape to aid
installation and to seal the pipe threads.

3
4. Install the third long hose into the outlet of
the pump (the outlet is the port facing
upward on the pump).
5. Install the short hose (approximately 2’ long)
into the pump inlet (the port at the end of the
pump that is facing horizontal).
6. Connect the pump inlet hose to the fitting at
the bottom of the CIP tank using the cam-
lock connector.
7. Turn off the MRO before connecting the CIP2 system or breaking any
water lines.
8. Choose the correct fittings supplied with the CIP2 system that will mate to
the INLET, REJECT, and PRODUCT ports of the reverse osmosis system
to be cleaned, and install them.
9. Connect the CIP pump outlet hose to the reverse osmosis water INLET
only.
WARNING: If the PRODUCT hose (PERMEATE) is momentarily pressurized due
to an incorrect connection (the CIP in reverse flow), the membranes
will be destroyed.
NOTE: When connecting the CIP2 to an AmeriWater MRO 3, 4 or 5, the existing
MRO hoses (one ¾” hose and two ½” hoses) will need to be cut about 12” from
the hose ends opposite the MRO. Install the Cam-Lock male/female connector
pair using the included hose barbs and hose clamps. Be sure that the Cam-Lock
connectors are “gendered” in such a manner that the hoses can be connected to
the correct fittings on the CIP2 tank (see below).
10. Connect the REJECT AND PRODUCT hoses to the CIP hoses near the
top of the CIP tank (hoses may be connected in either orientation).
11. Verify that all connections are made and are watertight.

5. HIGH pH CLEANING
NOTE: Be sure to remove carbon block filters (if applicable) from the RO before
performing cleaning. Filters will be clogged by cleaning solution if not
removed. Sediment filter may remain in the system.
AmeriClean B is used first for the removal of biological and colloidal foulants.
CAUTION: Do not to allow any cleaning solution to enter the PRODUCT
line going to the storage tank (if applicable).
1. Fill the CIP tank with RO product water (or softened water) to about 25”
deep in the tank. Water at 25” deep in the tank is approximately 27 gallons.
Water should be at or near 86°F for maximum cleaning effect.
2. Slowly add 3 lb (1,110 ml) [3 full bags] of AmeriClean B powder to the
water in the cleaning tank.
3. Agitate the solution until the powder is completely dissolved. It is important
to make sure all of the powder is dissolved before continuing.
WARNING: Wear appropriate eye and skin protection when handling the
membrane cleaning chemicals. The cleaners are high and low pH
chemicals and may cause severe chemical burns. Read the MSDS
for further information.
4. Open the valves that are connected to the CIP INLET, PRODUCT, and
REJECT hoses to permit flow from the CIP2 through the RO and back to the
CIP2 only. The MRO should be turned off (STANDBY) at this point.
5. Connect the power cord of the CIP2 pump to a 120 VAC receptacle and
allow the solution to begin circulating.
6. Remove the rear cover on the MRO.
7. There is a toggle switch on the backside of the controller. This switch
allows the MRO to operate with the CIP2 connected without sending the
system into an alarm condition. Move the toggle switch to the “ON” position.
8. Close the rear cover on the MRO.
9. Switch the Flush Valve on the RO from “Operate” to “Flush”.
10. Turn on the MRO and verify that the cleaning solution is recirculating and
flowing from the drain hose inside the CIP tank.
11. Allow the cleaning solution to recirculate for a minimum of 50 minutes.

7
a. Depending on the nature of the fouling, a soak period may be necessary.
If the membranes are not heavily fouled, proceed to step 11.
b. In cases of heavy fouling, turn off the RO and CIP pump and allow the
system to soak for a minimum of 30 minutes.*
* Contact AmeriWater Technical Support or your local AmeriWater dealer for custom cleaning procedures if
necessary.
c. After the soak time, turn on the CIP pump and RO, and allow the cleaning
solution to recirculate again for 30 minutes.
12. Disconnect the pump outlet hose from the CIP tank and direct the hose to a
drain. Continue running to drain until the CIP tank is empty (some solution
may need to be manually dumped out of the CIP tank).
CAUTION: Neutralization of the spent cleaning solution may be required
by local regulations. Verify the requirements of local
regulations prior to emptying the cleaning solution into the
drain. Use an approved waste container for chemical waste
disposal if required.
13. After removing the spent chemical from the CIP2 tank, and with the CIP2
pump discharge directed to drain, turn on the MRO and allow fresh water to
flow into and through the RO and CIP2 for 10 minutes or until the pH of the
water at the pump discharge is neutral (between 6 and 8).
14. Proceed to the low pH cleaning.
WARNING: Never allow AmeriClean A and AmeriClean B to mix! Mixing the
chemicals will cause an exothermic reaction which may result in
serious injury and damage to the equipment! Flush the system
thoroughly and verify the pH of the reject water is neutral prior to
switching chemicals!
NOTE: The 20” filter housings may trap some left over chemical solution causing
rinse out times to be high. To shorten the rinse time, remove and dump the filter
housing, then reinstall in the system. This allows the housing to fill with fresh
water and reduces time required for rinsing.

6. LOW pH CLEANING
AmeriClean A is used second for the removal of inorganic scale and metals.
1. Fill the CIP tank with RO product water (or softened water) to about 25”
deep in the tank. Water at 25” deep in the tank is approximately 27 gallons.
Water should be at or near 86 °F for the maximum cleaning effect.
2. Slowly add 3 lb (800 ml) [3 full bags] of AmeriClean A powder to the water
in the cleaning tank.
3. Agitate the solution until the powder completely dissolves. It is important to
make sure all of the powder is dissolved before continuing.
WARNING: Wear appropriate eye and skin protection when handling the
membrane cleaning chemicals. The cleaners are high and low pH
chemicals and may cause severe chemical burns. Read the MSDS
for further information.
4. Connect the power cord of the CIP2 pump to a 120 VAC receptacle and
allow the solution to begin circulating.
5. Turn the MRO on and verify that the cleaning solution is recirculating and
flowing from the drain hose inside the CIP tank.
6. Allow the cleaning solution to recirculate for a minimum of 50 minutes.
a. Depending on the nature of the fouling, a soak period may be necessary.
If the membranes are not heavily fouled, proceed to step 11.
b. In cases of heavy fouling, turn off the RO and CIP pump and allow the
system to soak for a minimum of 30 minutes.*
* Contact AmeriWater Technical Support or your local AmeriWater dealer for custom cleaning procedures if
necessary.
c. After the soak time, turn on the CIP pump and RO, and allow the cleaning
solution to recirculate again for 30 minutes.
7. Disconnect the pump outlet hose from the CIP tank and direct the hose to a
drain. Continue running to drain until the CIP tank is empty (some solution
may need to be manually dumped out of the CIP tank).
CAUTION: Neutralization of the spent cleaning solution may be required
by local regulations. Verify the requirements of local
regulations prior to emptying the cleaning solution into the
drain. Use an approved waste container for chemical waste
disposal if required.

8. After removing the spent chemical from the CIP2 tank. With the CIP2 pump
discharge directed to drain, turn on the MRO and allow fresh water to flow
into and through the RO and CIP2 for 10 minutes or until the pH of the water
at the pump discharge is neutral (between 6 and 8).
9. Turn OFF the MRO and disconnect the CIP2 system from the RO.
10. Operate the machine as described in the flushing section of the IRO or
MRO manual for at least one hour while the PRODUCT and REJECT hoses
are still directed to the drain.
The cleaner is sufficiently flushed when the pH and PRODUCT conductivity
are restored to normal service operating levels.
11. Press the POWER key on the front of the controller to put the unit into
“STAND-BY”
12. Disconnect the electrical power and gain access to the rear of the controller
to move the toggle switch to “OFF”. This will allow normal fault alarms to be
active.
13. Close the cover on the MRO and turn on the electrical power.
14. To return the MRO to “service”, close the PRODUCT AND REJECT valves
going to the CIP2, then, open the “IN-SERVICE” PRODUCT AND REJECT
so that flow is routed as intended in the “IN-SERVICE” mode. The CIP
INLET valve should have already been closed in step 9.
15. Cap or plug the fittings on the RO that were used to connect to the CIP2
accordingly.
16. At this point the RO is ready to be turned on and operated. Press the
POWER key to start the RO and monitor all the connections to be sure
there are no leaks.
17. Monitor the RO output and verify that conductivity is within specified range.
18. Drain the CIP2 system of residual water, place the hoses and pump back
into the tank, and move the CIP2 system to a place for storage until the next
use.
WARNING: DO NOT connect the MRO to the point of use and/or place the MRO
in service until the Product Water conductivity remains below the
setpoint and is not in alarm! Serious injury or illness to the patient
may result!
