- 적격 직원: If you are unsure about any part of the installation process, consult a qualified electrician or HVAC technician.
- 보호 장비를 착용하세요: Wear appropriate personal protective equipment, such as safety glasses and gloves, to prevent injury.
- 구성 요소 검사: Before installation, inspect the new motor and existing fan housing for any damage. Do not install damaged parts.
- 적절한 도구: Use only appropriate tools for the task to avoid damage to the motor or fan unit.
3. 설치 지침
This section outlines the general steps for replacing the motor in compatible Broan exhaust fan models. Specific fan models may have slight variations.
- 설치 준비:
- Ensure power to the fan unit is OFF at the circuit breaker.
- Remove the fan grille or cover to access the motor assembly.
- Carefully disconnect any electrical wiring from the old motor. Note the wiring configuration, taking photos if necessary.
- 기존 모터를 제거하세요:
- Locate the nuts or screws securing the old motor to the fan housing. These are typically two nuts.
- Carefully remove the fan impeller (plastic fan blade) from the motor shaft. You will need to reuse this component.
- Remove the old motor from the housing.
- Clean Fan Housing:
While the motor is removed, it is an opportune time to clean any accumulated dust or debris from the fan housing. Use a vacuum cleaner or damp cloth. Ensure the housing is dry before proceeding.
- 새 모터 설치:
- Position the new S99080521 motor into the fan housing. Ensure the motor mount aligns correctly with the mounting holes.
- Secure the motor using the original nuts or screws. Ensure it is firmly seated.
- 중요 참고 사항: In some cases, the motor mount may need to be reoriented. If the wiring exits the motor in a way that would interfere with the fan impeller or housing, carefully remove the motor mount, rotate the motor armature, and reattach the mount to ensure proper wire routing and clearance.
- Attach Fan Impeller:
- Slide the original plastic fan impeller onto the new motor's D-shaft. Ensure it is fully seated and secured. The D-shaft design prevents the impeller from spinning freely on the shaft.
- 배선 연결:
- Reconnect the electrical wiring to the new motor, matching the configuration noted during disassembly. Ensure all connections are secure.
- 마지막 단계:
- Replace the fan grille or cover.
- Restore power to the fan unit at the circuit breaker.
- 팬이 제대로 작동하는지 테스트하십시오.
