Xylem HYDROVAR WATERCOOLED - Manual (Page 13)

13
The Hydrovar-Watercooled contains electronic safety devices which switch off the control element
in the event of a fault, whereby the motor has zero current but remains energized and comes to a
halt. The motor can also be halted by mechanical blocking. If it is electronically switched off the
motor is disconnected from the mains voltage through the electronics of the Hydrovar-Watercooled
but is not potential-free in the circuit.
In addition voltage fluctuations, especially power failures can cause the system to switch off itself.
Repair of faults can cause the motor to start up again!
The system may only be put into operation when it has been earthened. In addition, equipotential bonding of all
pipes must be ensured.
The operating instructions must be read, understood and followed by the operating personnel. We point out that we
accept no liability for damage and operating disorders which are the result of non-compliance with the operating
instructions.
Transportation, Handling:
Check the Hydrovar-Watercooled immediately upon delivery/receipt of dispatch for damage or missing parts. If
any damage is visible, inform your distributor within 8 days from the delivery date.
The unit must be transported carefully and by competent personnel.
Avoid serious impacts.
Attention: Dispose of all packing materials in accordance with local regulations
