Compatibility and Installation

The Grundfos SCALA2 3-45-1 is specified for potable drinking-water systems only, with a maximum liquid temperature of 113 degrees F (45 degrees C). Confirm that the vessel provides compatible 200V to 240V AC single-phase 50/60 Hz power, appropriate circuit protection, 1-inch NPT/G plumbing, potable-water-compatible piping, required flow, and installation space before ordering. This model is not designed for saltwater, fuel, wastewater, or chemical-transfer use.

Maximum flow and head are pump ratings; actual delivered performance changes with suction lift, pipe diameter and length, fittings, filters, elevation, simultaneous fixture demand, pressure setpoint, and electrical supply. The IPX4D rating does not make the pump submersible. Follow Grundfos instructions for priming, mounting, inlet filtration, wiring, pressure setup, plumbing, and commissioning.
