Maintenance and repair may only be carried out by qualified per-
sonnel!
It is recommended to have the pump serviced and checked by Wilo-
Customer Service.
DANGER! Risk of fatal injury!
There is a risk of fatal injury due to electric shock when working on
electrical equipment.
• Work on electrical equipment may only be done by electricians
approved by the local electricity supplier.
• Before working on electrical equipment, switch it off and prevent
it from being switched on again.
• Follow the installation and operating instructions for the pump,
level control device and other accessories.
DANGER! Risk of fatal injury!
Failure to install safety devices on the terminal box or near the
coupling can cause electrical shock or contact with rotating parts,
potentially resulting in life-threatening injuries.
• After maintenance, all safety devices such as terminal box covers
or coupling covers that were removed must be reinstalled!
WARNING! Risk of injury due to the weight of the pump!
The pump itself and the parts of pump can be extremely heavy.
Falling parts pose a risk of cuts, crush injuries, bruises or impacts,
which may lead to death.
• Always use suitable lifting equipment and secure parts against fall-
ing.
• Never stand underneath a suspended load.
DANGER! Risk of burns or freezing to the pump when body parts
come into contact with the pump!
Depending on the pump or system operating conditions (fluid tem-
perature), the entire pump can become very hot or very cold.
• Keep a safe distance during operation!
• In the case of high water temperatures and system pressures, allow
the pump to cool down before all work.
• Always wear protective clothing and gloves when working.
NOTE
For all installation work, the forked spacer (Fig. 13, Item 10) is a man-
datory requirement for setting the correct impeller position in the
pump housing!
The air supply to the motor housing must be checked at regular inter-
vals. In case of contamination, ensure that an air supply is re-estab-
lished in order to allow the motor to cool sufficiently.
