Ɣ Be sure the drain hose discharges water properly. If connected incorrectly, it may cause leaks.
Ɣ Do not install the unit in any place where oil can seep onto the units, such as table or seating areas in
restaurants, and so forth. For these locations or social venues, use specialized units with oil-resistant
features built into them. In addition, use a specialized ceiling fan designed for restaurant use. These
specialized oil-resistant units can be ordered for such applications. However, in places where large
quantities of oil can splash onto the unit, such as a factory, even the specialized units cannot be used.
These products should not be installed in such locations.
