• If necessary, lever up and remove the thermal insulation shell
with a screwdriver
• 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.
• If necessary, fit the thermal insulation shell which can be
ordered separately.

cian approved by the local electricity supplier and in accord-
ance with the local regulations in force.

removed, there is a danger of electric shock by touching the
electrical components located inside and the contacts
underneath the front film.
