1. Important information:
(1) The initial 5 gallons of water must be discarded. This initial stage of water production is not drinkable or used as cooking water.
(2) After initial wetting, it is necessary to keep the original in a wetting state forever.
(3) During the long outage of the system, it is recommended that the membrane elements be immersed in the preservation solution to prevent microbial breeding in the system. Before using again, clean out the preservation solution.
(4) The membrane element has some tolerance to chlorine (hypochlorite) in short time. However, continuous contact may cause damage to membrane elements, so the above situation should be avoided.
2.General information:
(1) When the membrane element is first used, the product water in a tank should be released.
(2) Once the element is wetted, it should always be wetted.
(3) If the user does not strictly follow the operating limits and guidelines set in this specification, the limited warranty will fail.
(4) In order to prevent microbial growth during long-term suspend work, it is recommended that membrane elements be penetrated into the protective solution. The standard preservation solution contains 1.5% sodium bisulfite (food grade).
(5) Users should be responsible for the impact of the use of incompatible chemicals and lubricants on components.
