Installation and operating instructions • Wilo-Yonos GIGA2.0-I/-D • Ed.02/2023-08
DANGER
Danger of death due to lack of protective devices!
Due to missing protective devices of the electronic module or in the
range of the coupling/motor, electric shock or contact with rotating parts
can lead to life-threatening injuries.
• Before commissioning, protection devices such as electronic module
covers or coupling covers that were removed must be reinstalled!
• An authorised technician must check the functionality of the safety
devices on the pump, motor and electronic module prior to commis-
sioning!
• Never connect the pump without the electronic module!
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.
CAUTION
Dry running will destroy the mechanical seal! It may cause
leakage.
• Ensure that a dry run of the pump is not possible.
WARNING
There is a risk of burns or freezing upon coming into contact
with the pump/system.
Depending on the pump and system operating conditions (fluid temper-
ature), the entire pump can become very hot or very cold.
• Keep a safe distance during operation!
• Allow the system and pump to cool down to room temperature!
• Always wear protective clothing, safety gloves and safety glasses
when working.
DANGER
Danger of personal injury and material damage due to ex-
tremely hot or extremely cold pressurised fluid!
Depending on the temperature of the fluid, when the venting device is
opened completely, extremely hot or extremely cold fluid may escape in
liquid or vapour form. Fluid may shoot out at high pressure depending on
the system pressure.
• Always exercise caution when opening the venting device.
• Protect the electronic module from any water escaping when venting.
