3. Setup and Installation
- Power Disconnection: Before beginning installation, ensure that the power supply to the existing unit is completely disconnected at the circuit breaker or fuse box. Verify with a voltage tester.
- Remove Old Blower: Carefully disconnect any wiring from the old blower. Note the wiring configuration for proper re-connection. Unbolt and remove the old blower unit from its mounting location.
