Care of your CAFO948 Iron filter
To retain the attractive appearance of your new filter, clean occasionally with mild soap solution. Do not use
abrasive cleaners, ammonia or solvents. Ensure that there is no dust or debris on the bypass valve.
Winterizing the system
If the unit is to be winterized, the best way is to close the by-pass valve and unscrew the 2 screws adjacent to the by-
pass valves that hold the unit and the by-pass valve together, and carry the unit to a place where it will not be
subject to freezing temperatures.
