Voltage selection switch:
1. Disconnect the electrical power cord.
2. Use a screw driver to adjust the
voltage selection switch
at
the terminal box of the pump to the supply voltage:
”115/120” corresponds to 100-120 V and
”230/240” corresponds to 200-230 V.
• Check that the voltage selection switch is posi-
tioned correctly.
Note
: If the pump is switched on with wrong volt-
age selection, the motor may be damaged!
• Check every time before starting the pump.
•
Change the selection at the voltage selection
switch only if the pump is unplugged from
the power source.
