Replacing a Fan Unit

The appliance fan unit is a single unit made up of four individual fans to provide the air flow
required to maintain a proper operating temperature. The fan unit can provide proper airflow for
a short time even if an individual fan fails.
Before you replace a fan unit, you must first turn off power to the appliance.

Before You Begin

Physical access to the IP560 appliance
