Important information

1. The initial 5 gallons of produced water must be discarded. This initial production water is not potable and should not be used as cooking water.

2. After the initial wetting, the element needs to be kept permanently wetted.

3. During extended periods of system shutdown, it is recommended that the membrane element be immersed in a preservation solution to prevent the growth of microorganisms in the system. Before re-use, the preservation solution is washed off.

4. The membrane element has some tolerance to short term exposure to chlorine (hypochlorite). However, continuous exposure may lead to damage to the membrane element and should be avoided.
