1)
In a clean plastic container, mix 2.5 gallons / 10 liters of un-chlorinated fresh water with 100 grams
(1/3 container) of ECHOTec membrane preservative # 3 (Metabisulfite)
2)
Switch the three-way valve to the cleaning/storage position.
3)
Switch the diverter valve to the sample position.
4)
Open the pressure control valve all the way counter clockwise (two full rounds after the spring
releases).
5)
Use a large funnel or open container with barbed fitting to pour the solution into the
cleaning/storage hose or lead the hose into an elevated plastic container while running the high-
pressure pump. When the solution has been infused, switch off the watermaker.
Your watermaker is now prepared for a shutdown period of ten months.
CAUTION: After storage, discard the product water for at least thirty minutes of initial operation before
drinking or before use in food preparations.
MEMBRANE CLEANING PROCEDURE
ECHO Tec membrane element may 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 quality.
Fouling of the membrane will naturally occur during normal usage. 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 of operation.
Note: Do not clean when product salinity high. Clean only to restore output!
CAUTION: The use of chemicals or cleaning methods other than those outlined in the cleaning instructions
will void the ECHO Tec 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 onside 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.
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 10 ltr / 2.5 gal with 200 g or 2/3
container cleaning agent.
For safety reasons, we do not recommend you to install a 3 way re-circulating valve to facilitate the service
procedure. Disconnect the intake and reject water hose and lead them in the plastic container. Re-
circulate the solution intermittent 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 most of 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. Only if the performance does not improve, use the
acid cleaner #2 at the same ratio and instruction
