should be plugged into a standard electrical socket.
• The terminal box should not be opened for electrical connection.

8.1 Filling and venting
Fill the system correctly. The pump rotor housing is ventilated automatically,
even after short periods of operation. Short periods of dry running does not
damage the pump.
9 Maintenance
Maintenance and repair work should be carried out only by qualified
personnel!
CAUTION! Risk of damage to the pump!
The pump operates at 115 V and must not be connected to a 230 V electrical
supply. This will result in pump failure.
WARNING! Risk of Electrical shock!
Exposure to electrical energy must be prevented.
• When carrying out maintenance and repair work the pump must be switched
off and protected against unauthorised restarting.
• Damage to the connection cable must only be repaired by a qualified
electrician.
WARNING! Risk of scalding!
To prevent scalding prior to disassembling, turn power to the pump off, close
the isolation valves for a period long enough so the pump body does not feel
extremely hot to the touch. This will prevent steam flashing of extremely hot
water.
