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.
