5. INSTALLATION
5.1. Assembly (see FIGS. 1 and 5)
- Make sure that the circulator is accessible.
- Install directly on a horizontal or vertical pipe, on the
distribution loop return, after the drawing points.
- The motor shaft axis must always be horizontal.
- The arrow on the pump casing indicates the
direction of water flow.
- Install an isolating valves to facilitate removal and
other work on it.
5.2. Orientation of terminal box (see FIG. 5)
If necessary, the orientation of the motor, and with it
that of the terminal box, can be changed.
- Remove the motor coupling nut and turn the motor
to the desired position.
Take care not to damage the casing gasket,
and reinstall it correctly.
