The following chart illustrates the procedure for determination of RO membrane
performance. However, the chart represents only rough guidelines for
determining performance of RO membrane. Depending on your tap water
chemistry, the rejection characteristics of the membrane may vary significantly.

Temperature Extremes
1. The unit must be kept out of areas that are subject to freezing
temperatures.
2. High temperatures greater than 100° F (38° C) must be avoided. If
he unit is used outside, avoid putting the system in direct sunlight or
connecting it to a garden hose that may be exposed to sunlight.
