The Watertech Mascontrol 1¼" is an advanced electronic pressure switch designed to optimize the operation of water pumps in residential and commercial settings. This device ensures efficient water distribution by automatically starting and stopping the pump based on water flow and pressure changes, effectively replacing traditional expansion tank systems. Key Features: - Automatic Pump Control: Activates the pump when water is drawn, maintaining consistent pressure during use. - Dry Run Protection: Automatically shuts off the pump if water flow is insufficient, preventing damage from dry running. - Integrated Check Valve: Prevents backflow, ensuring a steady water supply and protecting the pump from potential damage. - Compact and Maintenance-Free: Eliminates the need for large expansion tanks, reducing system complexity and maintenance requirements. Technical Specifications: - Voltage: Single-phase 230V - Maximum Power: 2.2 kW (3 HP) - Maximum Operating Pressure: 10 bar - Temperature Range: 0°C to 65°C - Protection Rating: IP65 - Connections: 1¼" male and female threads Applications: Ideal for controlling pumps in applications such as: - Rainwater harvesting systems - Garden irrigation - Well water systems - Any system requiring clear water without abrasive substances Installation Recommendations: For optimal performance and longevity, install the Mascontrol 1¼" in a dry, frost-free environment. Ensure the device is mounted vertically to allow the mechanical check valve to function correctly. Avoid installation in areas prone to condensation or potential flooding. By integrating the Watertech Mascontrol 1¼" into your water pumping system, you can achieve reliable, efficient, and maintenance-free operation, ensuring a consistent water supply tailored to your needs.
