4. Installation
The compact design of the Atmos Pico simplifies installation. Follow these general guidelines:
- Monteringsposition: Install the pump in a horizontal position with the motor shaft horizontal. Ensure adequate space for ventilation and maintenance.
- Rørforbindelser: Connect the pump to the heating or air conditioning system piping using appropriate threaded fittings. Ensure all connections are watertight.
- Elektrisk tilslutning:
- Ensure the power supply is disconnected before wiring.
- Connect the power cable to the Wilo-Connector. The lateral positioning of the connector reduces the risk of collision with valves during installation.
- Follow the wiring diagram provided with the pump for correct connections (Live, Neutral, Earth).
- Systempåfyldning og udluftning: After installation, fill the system with water and thoroughly vent the pump and the entire system to remove any trapped air. Do not operate the pump until it is fully vented and filled with water.
5. Betjeningsvejledning
The Atmos Pico features an intuitive LED display and "Green Button" technology for easy operation.
- Tænd: Once installed and the system is filled, switch on the power supply to the pump. The LED display will illuminate.
- Green Button Technology: The "Green Button" is the primary control for setting the pump's operating mode and characteristic curves.
- Valg af tilstand: Press the Green Button to cycle through available operating modes (e.g., constant differential pressure, variable differential pressure, constant speed). The selected mode will be indicated on the LED display.
- Performance Adjustment: Within each mode, further presses or a long press of the Green Button may allow adjustment of the differential pressure (prevalence) or speed settings. The LED display will show the current setting.
- Automatic Adaptation: The integrated electronic control automatically adapts the pump's performance to the system's requirements based on the selected differential pressure setting.
- Overvågning: The LED display provides continuous feedback on the selected operating mode and current performance.
Refer to the detailed operating instructions provided with the physical product for specific characteristic curves and advanced settings.
6. Vedligeholdelse
The Wilo Atmos Pico is designed for reliable, low-maintenance operation. Regular checks can help ensure its longevity and efficiency.
- Årlig inspektion: It is recommended to have the pump inspected annually by a qualified technician.
- Systemets vandkvalitet: Ensure the system water quality is maintained according to manufacturer guidelines to prevent corrosion and deposits.
- Rensning: Keep the exterior of the pump clean and free from dust and debris to ensure proper heat dissipation.
- Udluftning: Periodically check and vent the system if unusual noises or reduced performance are observed.
- Frostbeskyttelse: If the system is shut down during cold periods, ensure adequate frost protection measures are in place to prevent damage to the pump.
Always disconnect the power supply before performing any maintenance tasks.
