PNEG-924 Shutter Manual Override Kit
This kit is designed to allow the shutter assembly to be opened and closed manually . The intent of this
installation is to prevent the shutter blades from fluttering when used with a heater unit in high static
pressure / low airflow situations. It does not matter which side, left or right, the handle is mounted. This
is dependent on how the fan/heater unit is mounted to the storage tank.
Installation
Locate the mounting hole for the handle bracket on the Shutter Frame T op.
