• Loosen the internal hexagon screws
• Turn the motor housing, including control module.
Note: Generally turn the motor head before the installation is
filled. When turning the motor head in an installation which is
already filled, do not pull the motor head out of the pump hous-
ing. Turn the motor head with a small amount of pressure on the
motor unit so that no water can come out of the pump.
CAUTION! Risk of damage to property!
The gasket may be damaged when the motor housing is
turned. Replace defective gaskets immediately.
• Screw the internal hexagon screws back in and tighten them.
• Fit the thermal insulation shell.

DANGER! Danger of death!
A fatal shock may occur if the electrical connection is not
made correctly.

cian approved by the local electricity supplier and in accord-
ance with the local regulations in force.
• Disconnect the power supply before any work.
• If setting and operating elements are improperly removed,

ponents are touched.

control!
CAUTION! Risk of damage to property!
When the pump is switched on/off by external control
devices, the mains voltage pulsing (e.g. phase angle control)
must be deactivated to prevent damage to the electronics.
