WATER SUPPLY REQUIREMENTS
NOTE: Install the RO-150 in the cold water line only. Installation of the water filter system in a hot water line can
damage the filter housing. System performance varies with the incoming water supply temperature. Optimum
performance is achieved when water temperature is 70° F. For each 10° F drop in water temperature, a decrease
in water production of 10% will be observed. A larger storage tank may be required when the water temperature is
less than 55° F.
NOTE: The following are recommended inlet water supply parameters. Exceeding these parameters may
decrease system performance or result in more frequent filter changes. Most municipal water supplies will meet
these conditions with the exception of water hardness. In cases where water hardness exceeds the maximum
recommended levels, life of the RO membrane may be shortened. Proper system performance checks will
determine if the membrane needs replacement.
