Service and maintenance

9.5.2

Loosen housing screws

Loosen the screws securing the pump to the lantern via the studs. Place the pump on the
flange of the lantern for better accessibility of the screws. The suction nozzle is directed
upwards.

9.5.3

Remove housing

As shown in the picture, pull the housing over the studs upwards

NOTE

As a reminder: All metallic tools are to be kept away from the magnetic field of the inner magnet. The

working area when disassembling the pump must be clean and free of metallic parts
