DANGER
Danger of death due to lack of protective devices!
Due to missing protective devices of the terminal box or in the range of
the coupling/motor, electric shock or contact with rotating parts can lead
to life-threatening injuries.
• Before commissioning, safety devices such as terminal box covers or
coupling covers that were removed must be reinstalled!
• An authorised technician must check the functionality of the safety
devices on the pump and motor prior to commissioning!
WARNING
Danger of injury due to fluid shooting out and components
coming loose!
Not installing the pump/system correctly can lead to serious injuries dur-
ing commissioning!
• Carry out all work carefully!
• Keep a safe distance during commissioning!
• Always wear protective clothing, safety gloves and safety glasses
when working.
NOTICE
It is recommended to have the pump commissioned by the Wilo cus-
tomer service.
The pump has to reach ambient temperature before commissioning.
•
Check whether the shaft can be rotated without any grinding. In case the impeller is
blocked or grinds, loosen the coupling screws and tighten them again with the specified
torque. (See table on screw tightening torques).
•
Fill and vent the system appropriately.
CAUTION
Dry running will destroy the mechanical seal! It may cause
leakage.
• Ensure that a dry run of the pump is not possible.
