4. Fit the control box. The plug must fit easily into
the terminal plug of the stator.
The paste will make the control box stick to the
pump head.
5. Fit and tighten the three screws (d). See fig. B.
6. Fit the expansion module, if any. See section
4. Replacement of expansion module.
7. Connect all wires in the same positions as before
dismantling.
8. Close the control box cover. Fit and tighten the
screws (c). See fig. B.
9. Switch on the electricity supply.
The pump is now ready for operation. See section
6. Start-up.
3.1 Changing the control box position
Change the control box position as follows:
1. Remove the inspection screw (1) and the four
screws (2) in the pump head. See fig. 2.
2. Lift off the pump head (3). Keep the rotor (4) in
place using a suitable tool, e.g. a tee key (M8)
(5). See fig. 3.
3. Check that the O-ring (6) is intact.
A defective O-ring must be replaced.
4. Hold the pump head/control box (3) in the desired
position.
5. Lower the pump head over the rotor. Keep the
rotor in place as described in point 2.
6. Fit and tighten the four screws and the inspection
screw.

Dismantling
1. Switch off the electricity supply to the pump, and
make sure that it cannot be accidentally switched
on during replacement.
2. Remove the screws (c) from the control box
cover, and open the cover. See fig. B.
3. Before wires are disconnected, carefully note
their position.
4. Remove all wires from the expansion module.
5. Remove the screw (q) holding the module.
See fig. J.
6. Remove the module (r). See fig. J.
Note
The connection across terminals 7 and
8 must be removed if an external on/off
switch is to be connected.
Warning
Before any dismantling of the pump,
the system must be drained or the
isolating valves on either side of the
pump must be closed as the pumped
liquid may be scalding hot and under
high pressure.
