Grundfos SCALA2 A compact self-priming (max. 8 m) domestic water system with whisper-quiet water-cooled permanent magnet motor and comfortable constant pressure control. Thanks to the comfort control, a constant pressure is set at the tap point, regardless of fluctuating pre-pressure or decrease. Thanks to the latest efficient motor technology, the SCALA2 requires only half of the electrical power consumption (max. 550 W) of a typical domestic water system with the same hydraulic power (in litres per minute). Thanks to the water-cooled fanless motor, the SCALA2 operates with only a whisper-quiet 47 dB(A), which corresponds to the noise level of a modern dishwasher. Thanks to the high protection class IPX4D (protected against spray water), the SCALA2 domestic waterworks can also be used for direct frost-free outdoor installation. To simplify the connection of the pressure and suction line, the SCALA2 is equipped with 5 degree swivel connectors. The filling nozzle and the emptying pot can also be opened and closed without tools. With only 23 l room volume, the SCALA2 requires approx. 75% less installation space than traditional domestic water systems with membrane pressure tank. In order to protect the SCALA2 against the penetration of insects, it is equipped with an insect screen on the bottom. The robust yet lightweight aluminium housing combines all the components of a domestic waterwork: * High efficiency motor with frequency converter. * Pressure sensor for constant pressure control. * control board * Integrated check valves * Membrane pressure container (0.66 litres). * hydraulic unit The user-friendly display allows you to make the following settings and read information: * Pump on/off * Set and read the desired constant pressure value. * Button for alarm acknowledgment. * Key lock. * Multi-function LED to indicate the operating status. The SCALA2 independently protects itself against a variety of possible hazards in the domestic water supply, displays them on the bottom of the operating display and automatically restart attempts at defined alarms: * LED 1: Over and under voltage. * LED 2: engine block. * LED 3: anti-clocking (small leaks), selectable. * LED 4: dry run protection. * LED 5: overpressure (> 6 bar). * LED 6: flood protection (max. 30 min permanent runtime), selectable. * LED 7: Exceed/below ambient temperature (0 °C to +55 °C). Technical details: * Rated operating point: 3 m3/h at 27 m. * Max. Q/H: 4 m3/h and 45 m. * Ambient temperature: 0 to 55 °C. * Max. Operating pressure: 10 bar. * Max. Inlet pressure: 6 bar. * Connection: G1 composite (5 swivels). Electrical data: * Power consumption: 550 W. * Voltage: 1 x 200-240 V: 50Hz. * Rated current: 2.8 A. * Standby: 2 W. * Protection class: (IEC 34-5): IPX4D. * Cable length: 2 m with Schuko plug.
