Commissioning
CAUTION
Risk of property damage due to incorrect insulation!
The discharge cover and the bearing bracket must not be insulated.
WARNING
Risk of injury due to lack of protective equipment!
(Serious) injuries can occur due to lack of protective equipment.
• Do not remove the unit casings of moving parts (such as that of the coupling)
during machine operation.
• Always wear protective clothing, protective gloves and protective goggles when
working.
• Do not remove or disable the safety devices on the pump and motor.
• An authorised technician must check the functionality of the safety devices on
the pump and motor prior to commissioning.
CAUTION
Risk of material damage due to unsuitable operating mode!
Operating outside of the duty point impairs the pump efficiency and can damage the
pump. Operating with the shut-off devices closed for more than 5 minutes is not re-
commended and generally dangerous in the case of hot fluids.
• The pump must not be operated outside of the specified operating range.
• Do not operate the pump with the shut-off devices closed.
• Make sure that the NPSHA value is always higher than the NPSHR value.
CAUTION
Risk of material damage due to the formation of condensate!
When using the pump in air-conditioning or cooling applications, the formation of
condensate can cause motor damage. The motors are equipped with condensate
drainage holes, which are factory-sealed with plastic plugs.
• Open the condensate drainage holes in the motor housing at regular intervals and
drain the condensate.
• Then reseal the condensate drainage holes with plastic plugs.
NOTICE
If the plastic plugs are removed, protection class IP55 is no longer ensured!
ƒ
Electrical work: A qualified electrician must carry out the electrical work.
ƒ
Operation/control: Operating personnel must be instructed in the functioning of the
complete system.
NOTICE
The standard version of the Wilo-Yonos GIGA-N pump has no air vent valve. The
suction line and pump are vented via a suitable venting device on the pressure
flange of the pump. An optional air vent valve is available.
