Installing Centrifugal Filter Fan
INSTALLATION
To install the filter fan, use the air pump pulley to draw it into position. Draw the fan down evenly by tightening the bolts evenly. As the filter fan is
being drawn into position, make sure that the outer edge of the fan draws into the air pump housing. A slight interference between the air pump housing
and the filter fan outer lip is normal and may cause a squeal noise upon initial operation. Do not attempt to install filter fan with a hammer or rubber
mallet as the filter is made out of plastic and is very brittle.
