1. Introduction
This manual provides essential information for the installation, operation, and maintenance of the ESBE Type 98 Servomotor. The ESBE Type 98 is designed for precise control of mixer valves within heating, ventilation, and air conditioning (HVAC) systems, specifically for mixer valves ranging from DN15 to DN150. Proper adherence to these instructions will ensure optimal performance and longevity of the device.

2. Setup and Installation
The ESBE Type 98 Servomotor is intended for professional installation. Ensure all local codes and regulations are followed during the installation process. This servomotor is compatible with various mixer valves, including those from ESBE, Thermoflux, and Klimawo, designed for DN15 to DN150 pipe sizes.
2.1 Pre-Installation Checks
- Verify that the servomotor model (Type 98) is appropriate for your specific mixer valve and system requirements.
- Ensure the power supply matches the servomotor's electrical specifications (not detailed in provided data, consult product label).
- Inspect the servomotor for any visible damage prior to installation.
2.2 Mounting the Servomotor
- Carefully align the servomotor with the shaft of the mixer valve.
- Secure the servomotor to the valve body using the provided mounting hardware. Ensure a firm and stable connection to prevent vibration and misalignment.
- Confirm that the mechanical connection allows for the full range of motion of the mixer valve.
2.3 Electrical Connection
All electrical work must be performed by a qualified electrician. Refer to the wiring diagram provided with the servomotor packaging for specific connection details. Ensure the power is disconnected before making any electrical connections.
3. Operating Instructions
The ESBE Type 98 Servomotor operates by rotating the mixer valve to control the flow of fluid within the system. The red triangular indicator on the front of the unit provides a visual representation of the current valve position.
3.1 Initial Start-up
- After successful installation and electrical connection, restore power to the system.
- The servomotor may perform an initial calibration cycle to determine the end positions of the mixer valve. Observe the indicator for movement.
- Verify that the servomotor responds correctly to control signals from the system's controller.
3.2 Position Indication
The clear circular dial with red and blue segments, along with the red triangular indicator, allows for visual confirmation of the valve's open/closed or mixing position. The specific meaning of the red and blue segments depends on the valve type and system configuration.
4. Maintenance
The ESBE Type 98 Servomotor is designed for reliable, long-term operation with minimal maintenance. Regular inspections are recommended to ensure continued optimal performance.
4.1 Routine Checks
- Periodically check the servomotor for any unusual noises or vibrations during operation.
- Inspect the mounting hardware for tightness and ensure the servomotor remains securely attached to the mixer valve.
- Keep the exterior of the servomotor clean and free from dust or debris. Use a soft, dry cloth for cleaning.
4.2 Cleaning
Do not use abrasive cleaners or solvents on the servomotor casing. A damp cloth can be used for stubborn dirt, ensuring no moisture enters the internal components.
5. Troubleshooting
If the ESBE Type 98 Servomotor is not functioning as expected, consider the following general troubleshooting steps. For complex issues, contact a qualified technician.
5.1 Common Issues
- Servomotor not moving: Check power supply and electrical connections. Verify that the control system is sending appropriate signals.
- Incorrect valve position: Ensure the servomotor is correctly mounted and calibrated to the mixer valve. Check for any mechanical obstructions.
- Unusual noise: This could indicate a mechanical issue with the servomotor or the mixer valve. Disconnect power and inspect for any loose parts or foreign objects.
Always disconnect power before attempting any inspection or repair work on the servomotor or associated components.
