TROUBLESHOOTING GUIDE FOR MEMBRANE:
The following chart illustrates the procedure for determination of RO membrane
performance. However, the chart represents only rough guidelines for determin-
ing performance of RO membrane. Depending on your tap water chemistry, the
rejection characteristics of the membrane may vary significantly.
Method of Calculate %

*Caution: This test is not to be used on softened water sources.
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.
