Filling And Venting - Wilo Stratos PARA Série Notice De Montage Et De Mise En Service

English
8 Commissioning
The danger information and warnings in Chapters 7, 8.5 and 9 must be observed!
Prior to commissioning the pump, check that it has been installed and connected correctly.
8.1

Filling and venting

NOTICE: Incomplete venting will lead to noises being produced in the pump and unit.
Prime and vent the unit correctly. The pump rotor chamber is vented automatically after
a short operating period. Dry running for short periods will not harm the pump.
WARNING! Risk of personal injury and material damage!
It is not permitted to remove the motor head or the flange connection / threaded pipe
union for the purpose of venting the system!
• There is a risk of scalding!
Escaping fluid can lead to injuries and damage to property.
• Risk of burns if the pump is touched!
Depending on the pump or system operating conditions (fluid temperature), the entire
pump can get very hot.
8.2 Operation
Faults of electronic devices due to electromagnetic fields
Electromagnetic fields are created during the operation of pumps with frequency con-
verter. Interference of electronic devices may be the result. The result may be a device
malfunction, which can result in damage to the health or even death, e.g. of persons car-
rying implanted active or passive medical devices. Therefore, during operation the pres-
ence of any persons e.g. with cardiac pacemakers in the vicinity of the unit/pump should
be prohibited. With magnetic or electronic data media, the loss of data is possible.
8.3 Decommissioning
The pump must be decommissioned before conducting maintenance, repair or disman-
tling work on the system.
DANGER! Risk of fatal injury!
There is a risk of fatal injury from electric shock when working on electrical devices.
• Have work on the electrical part of the pump carried out strictly only by a qualified
electrician.
• Before starting any maintenance and repair work on the system, disconnect the pump
from the power supply, and make sure it cannot be switched back on by unauthorised
persons.
• Work on the control module may only be started after 5 minutes have elapsed, due to
the dangerous residual contact voltage.
• Check whether all connections are voltage-free.
• The pump may still be live even in voltage-free state. The drive rotor induces a dan-
gerous contact voltage at the motor contacts.
Close the shut-off devices in front of and behind the pump.
• If the control module/cable is damaged, do not operate the pump.
WARNING! Risk of burns!
Risk of burns if the pump is touched!
