ข้อมูลด้านความปลอดภัย
สำคัญ: Installation and maintenance of boiler components should only be performed by qualified and certified technicians. Improper installation can lead to serious injury, property damage, or malfunction of the boiler system. Always disconnect power and water supply to the boiler before beginning any work.
- Ensure the boiler is completely depressurized and cooled before handling any parts.
- สวมใส่อุปกรณ์ป้องกันส่วนบุคคล (PPE) ที่เหมาะสม รวมถึงถุงมือและอุปกรณ์ป้องกันดวงตา
- Verify that the replacement part is compatible with your specific boiler model (Junkers ZWC 28/28 3 MFK 31).
- Follow all local codes and regulations for boiler installation and repair.
การติดตั้ง (Setup)
This hydraulic part is a direct replacement for the original component in Junkers ZWC 28/28 3 MFK 31 boilers. Professional installation is highly recommended.
- การตระเตรียม: Turn off the boiler's power supply at the main breaker. Close the main water inlet valve to the boiler and drain the system if necessary. Allow the boiler to cool down completely.
- เข้าถึง: ถอดหม้อต้มออกอย่างระมัดระวังasing to gain access to the hydraulic block. Refer to your boiler's specific service manual for instructions on accessing internal components.
- การถอดชิ้นส่วนเก่า: Disconnect all water lines and electrical connections (if any) from the existing hydraulic part. Note their positions for reassembly. Remove any mounting screws or clips securing the old part.
- การติดตั้งชิ้นส่วนใหม่: Position the reconditioned hydraulic part in the correct orientation. Secure it with the appropriate mounting screws or clips. Reconnect all water lines, ensuring a tight, leak-free seal. Reconnect any electrical wiring according to the boiler's wiring diagram.
- System Refill and Test: Slowly open the main water inlet valve to refill the boiler system. Bleed any air from the system. Check for leaks around all connections. Restore power to the boiler and test its operation according to the manufacturer's guidelines. Monitor for proper water flow and heating.
