Includes 6-1/2 foot power cord - 1 phase - This is a fully integrated, self-priming, compact pump for pressure boosting in domestic applications. SCALA2 incorporates integrated speed control enabling the keeping of the perfect pressure at the taps, meaning that the pump performance will increase with increasing demand. SCALA2 can be installed in three easy steps: 1. Connect the pipes. 2. Prime the pump. 3. Plug the pump into the power outlet and the pump will start. Grundfos SCALA2 has all the components necessary to ensure a comfortable pressure: intelligent controller, integrated speed-controlled drive, integrated tank integrated sensors, and integrated non return valves. As it is self priming, the SCALA2 is able to pump water from a level below the pump. Provided it is filled with water, the pump is able to lift water from a depth of 8 m in less than 5 minutes. This facilitates easy installation and start up of the pump and provides more reliable water supply in installations where there is a risk of dry running and leakages in suction hose or pipes. If exposed to dry running, water shortage or excessive temperature, blocked pump, or in case of seizure or overload, the pump will stop automatically, thus preventing a motor burnout. The pump features an automatic reset function. Restarting will be attempted every 5 minutes 8 times, thereafter new restart attemps will occur every 24 hours. The automatic reset function can be deactivated. Thanks to its hydraulic design, permanent magnet motor and water cooling, the pump is extremely low-noise, and is suitable for indoor or outdoor use. The built in pressure tank reduces the number of starts and stops in case of leakages in the pipe system, causing less wear on the pump. SCALA2 requires no maintainance, but it is recommended to keep the pump clean, check the non return valves and keeping the ventilation holes free of dust
