• To prevent significant increases in motor temperature and excessive
load on the pump, coupling, motor, gaskets and
bearings, no more than 10 switch-on procedure
should be performed per hour.
Have maintenance and repair work carried out by qualified
personnel only!
It is recommended to have the pump serviced and checked by
Wilo customer service.
When drafting a maintenance plan, expensive repairs can be avoided
and a fault-free operation of the system can be achieved with a min-
imum of maintenance effort.
DANGER! Risk of fatal injury!
There is a risk of fatal injury from 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 secure
it against being switched on again.
• Any damage to the pump connection cable should always be
rectified by a qualified electrician only.
• Never use an object to poke around the openings on the terminal
box or motor and never insert anything into the module or motor!
• 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.
• Immediately after maintenance, all previously removed safety
devices, such as terminal box covers or coupling covers, must be
reinstalled.
DANGER! Risk of fatal injury!
The pump itself and pump parts 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
falling.
• Never stand underneath a suspended load.
• Make sure the pump is securely positioned and is stable during
storage and transport as well as prior to all installation and other
assembly work.
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
temperature), 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, protective gloves and protective
goggles when working.
