Arrows on the side or bottom of the pump chamber
indicate direction of flow through the pump. Grundfos
Miximizer pumps can be installed in both vertical and
horizontal lines. Flow direction should be from the boiler
loop into the system loop.
The pump must be installed with the motor shaft posi-
tioned horizontally. Under no circumstances should the
pump be installed with the shaft vertical or where the
shaft falls below the horizontal plane (Fig.2).
