MEMBRANE CLEANING PROCEDURE
The ECHO Tec. Watermaker must be chemically cleaned when the product water output drops by
15% of the specified amount. The frequency of this occurring will vary greatly depending upon
feed water. Fouling of the membrane will naturally occur during normal usage of the ECHO Tec.
Watermaker. Increased amounts of fouling without proper cleaning of the membrane will reduce
the performance of your water maker. A drop in production of approximately 10% is normal and
expected during the first year.
CAUTION: The use of chemicals or cleaning methods other than those outlined in the
cleaning instructions will void the ECHO Tec. warranty. Nonionic surfactants for membrane
cleaning or other chemicals not approved in writing by Echo Marine Ltd. will void the
element warranty.
CAUTION: Cleaning chemical #1 is an alkaline detergent. See warning label on side of the
container and observe all safety precautions on label.
CAUTION: Cleaning chemical #2 is an acid, a mineral scale remover. See warning label on
side of container and observe all safety precautions on label.
CAUTION: Do not mix different cleaning chemicals together. Do not use different cleaning
chemicals together at the same time. Mix the cleaning chemicals separately and use them
separately.
Note:
All cleaning and preserving procedures can be done with either sea water or non-chlorinated
freshwater. However, the cleaning process is more effective using non-chlorinated freshwater.
To clean the ECHO Tec. reverse osmosis membrane mix a solution of 1.5 to 2% by weight with
warm non-chlorinated water (113° F / 45° C) in a clean plastic container.
Use 10ltr. / 2.5gal (with 200g / 2/3 container cleaning agent) for one 40” membrane and 4ltr/1gal
(with 40g cleaning agent) for every additional membrane.
For safety reasons we do not recommend to install a 3 way re-circulating valve. Disconnect the
intake and reject water hose and lead them in the plastic container. Re-circulate the solution
without pressure
for up to 60 min. There will be no flow at the fresh water outlet.
CAUTION: Observe the maximum operating temperature of 113° F / 45° C. The high
pressure pump might over heat the solution on re-circulating.
It is important that the fresh water, remaining from the last flush is dumped before the reject hose is
led in the cleaning bucket for re-circulation in order to avoid diluting the solution.
Use cleaning chemical #1 first. If the performance does not improve use the acid cleaner #2 at the
same ratio and instruction.
