Float switch:
• Fill the chamber with clean water, until the float switch is fully covered
• Turn the isolator to the on position

• Turn the isolator to the off position
High level alarm:
• Fill the tank with clean water, until the float switch and high level alarm
are fully submerged
• Turn the isolator to the on position and the red beacon will illuminate
• As the water level drops the high level alarm float tips to indicate the
tank is empty, turning off the beacon

wired incorrectly
START UP
Starting the pump:
The pump operates automatically via the combined float switch. Before starting the
pump, make sure that:
• The voltage and frequency specified on the pump’s nameplate are
suitable for the power supply available
• There are no signs of damage to the pump or its power cord
• The electrical connection is made in a dry place, protected against any risk
of flooding
• Any extension cables must be suitable for the intended purpose
Pump precautions:
• The pump must never be carried, lifted or made to operate hanging from
the power cable
• The pump should not be started more than 20 times in one hour so as
not to subject the motor to excessive thermal shock
If you need to know more about the pump specification, please contact WPL.
