- Standard EC motors operate at a minimum temperature of -25°C. For other conditions, consult the technical department.
- Motors with diameters of 250, 315, and 350 mm have built-in thermal protection; 450 and 500 mm motors require a control panel connection for thermal protection.
- Ensure rpm adjusting systems are compatible with the motor to avoid noise and damage.
- Ensure the power supply circuit is open before making electrical connections.
- Apply thermal protection systems on power lines.
- Position the defrost cycle temperature probe in the coldest areas of the exchangers to prevent ice formation and ensure no ice remains at the end of the cycle.
- Diagrams for single-phase and three-phase AC motor fans include cable connections, safety switches, and power supply requirements.
- High-speed and low-speed motor connection diagrams are specified for 3~400 V 50-60 Hz systems.
- Connection Box: Used for signal and alarm connections.
- Screened Cable: Recommended to prevent interference.
- Power Supply: Typically 230V 1PH 50-60Hz for single-phase systems.
- Ensure the power supply circuit is open before making electrical connections.
- Apply thermal protection systems on power supply lines.
- Place the defrosting-end temperature probe in the coldest areas of the exchangers to prevent freezing.
- Ensure no ice remains on the exchanger at the end of the defrosting cycle.
- Avoid damaging electrical insulations when replacing heating elements.
- Use a screened cable for signal and alarm connections.
- Connect 24V to D1 to enable the fan, applicable only for Ziehl-Abegg fans.
- Specifications for various models (BOREA 35, 31, 25, 50, 45) include finned coil dimensions and power ratings.
- Each model includes the number of coils, power ratings (RC and RT), and total power output.
The document outlines maintenance and replacement procedures, emphasizing disconnecting the power supply before maintenance. Specific instructions are provided for replacing motors and heating elements in different Borea models.
Power supply standards include 230V and 400V configurations at 50 Hz, applicable to various Borea models.
Ensure operations prevent liquid or freon leakage during maintenance. Parts should be accessible for easy replacement and cleaning.
Tables provide power ratings for different Borea models, indicating total power output (RC+RT) and the number of components like batteries and basins. Dimensions of finned coils and required components for each model are specified.
- Ensure power is disconnected before maintenance.
- Follow specific procedures for motor and heating element replacement.
- Adhere to power supply standards for safe operation.
- Prevent leakage during maintenance.
- Counter-Tray: Remove rivets, disconnect terminals, replace the heating element, and restore fastening.
- Conveyor (BOREA 44-50): Follow a similar procedure for specific models.
- Pack: Remove screws, disconnect terminals, extract and replace the heating element, and restore fastening.
- Freon, CO2, Glycol systems with standard and special pumped modes.
- Tubing materials include copper and stainless steel with specific maximum pressure ratings for different substances (e.g., Freon, Glycol, CO2).
Products are warranted for 3 years against manufacturing defects, excluding corrosion damage. Unauthorized repairs void the warranty.
Avoid harmful substances and hard objects. Use specific pressures for hydraulic and compressed air cleaning, maintaining a safe distance from fans and electrical parts.
Compliance with various EU directives including Low Voltage, Pressure Equipment, and Electromagnetic Compatibility. Adheres to safety standards for machinery and electrical appliances.
