6. Fan, wheels, housings and drive assemblies 6. should
be checked for dirt buildup annually and cleaned
if necessary to keep them from becoming unbal-
anced and to prevent loss of airflow. Clean with
compressed air to reduce any dirt, dust, lint or larger
particulates that have bonded to the fan impeller
housing or drive assembly. Block dirt from entering
the unit and ductwork if necessary or remove fan
assembly from unit. Alternatively use low pressure
steam, a degreaser and rag. If a sheave requires
cleaning, detergent and water can also be used. En-
sure the belt is dry before starting up the unit.
