Connect an electrically conductive 1/2 in. ID (minimum) air hose to supply air to the system air
controls. Packages without an elevator will not have an elevator control, and packages without a
feed pump will have the connection for the pump air hose plugged. Install an air filter upstream of
the system to remove harmful dirt and moisture from the air supply. To order an air filter, order part
106148 (3.8 in. npt, 20–micron element, 5 oz. bowl, without gauge).
