Informações de segurança
Importante: 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.
- Utilize equipamento de proteção individual (EPI) adequado, incluindo luvas e proteção ocular.
- 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.
Instalação (Configuração)
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.
- Preparação: 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.
- Acesso: Remova cuidadosamente a caldeira casing to gain access to the hydraulic block. Refer to your boiler's specific service manual for instructions on accessing internal components.
- Remoção da peça antiga: 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.
- Instalação da nova peça: 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.
- Recarga e teste do sistema: 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.

Função (Operacional)
The hydraulic part (or hydraulic block) is an integral component of the boiler's water circuit. Its primary function is to manage and direct the flow of water within the boiler, facilitating both heating and domestic hot water production. It typically integrates various sensors, valves, and flow switches that work in conjunction with the boiler's control unit to ensure optimal performance and safety. Once correctly installed, this reconditioned part will function automatically as part of the boiler's overall system.

Manutenção
As a reconditioned part, this hydraulic block has been inspected and restored to optimal condition. Regular maintenance of the overall boiler system is crucial for its longevity and efficient operation. This includes:
- Annual Boiler Service: Have your boiler serviced annually by a qualified technician. This service typically includes checking for leaks, inspecting components, and ensuring proper system pressure.
- Verificação da pressão do sistema: Regularly monitor your boiler's pressure gauge. Maintain pressure within the manufacturer's recommended range (usually between 1 and 1.5 bar when cold).
- Sangria dos radiadores: Periodically bleed air from your radiators to ensure efficient heat distribution, which can indirectly affect the hydraulic system's performance.
- Qualidade da água: Ensure the boiler system's water quality is maintained to prevent scale buildup and corrosion, which can impact hydraulic components.
Solução de problemas
If you experience issues after installing the hydraulic part, consider the following common troubleshooting steps. For complex problems, always consult a qualified technician.
| Problema | Possível causa | Solução |
|---|---|---|
| Vazamento de água | Loose connections, damaged seals during installation. | Turn off water supply, tighten connections, replace seals if necessary. Consult a technician if leaks persist. |
| No Hot Water / Heating | Incorrect installation, air in the system, other boiler component failure. | Check boiler pressure, bleed radiators. Verify all connections. Contact a qualified technician for diagnosis. |
| Unusual Noises from Boiler | Air in the system, pump issues, or other component malfunction. | Bleed radiators. If noises persist, consult a technician. |
