Start Up; Maintenance - PRETUL BOS-1-1/2SPP Manual

Float Switch
• The float switch goes On and OFF automatically
depending on the water level height. When the float
switch is placed into the same height as the transport
handle, the pump starts; and when it goes down to
approximately 4", it turns it off.
• To control the float switch manual and prevent the
pump to automatically shut off, you may set the switch
cable through the transport handle (D) so that the float
cannot plunge down and shut off the pump.
CAUTION • When controlling the float switch
manually keep on supervising the pump's functioning and
prevent the water level to be so low it will make the pump
operating dry.

Cleansing and Care
• Inspect regularly all the mounting screws and double
check the screws are correctly tightened. In the event one
of the screws is loose, tighten immediately.

base can be removed unscrewing the pan head screw fixing
it to the pump's body. This way you can clean the turbine.
For safety reasons a damaged turbine can only be replaced

Start Up

WARNING • Avoid the pump operating dry,
otherwise it can break down. When the water stops
flowing, disconnect the pump immediately.
• The motor thermal protector shuts off the pump
automatically in the event of overheating. Once the motor
has cooled down, it will start again automatically.
• After pumping chlorinated water from a swimming pool
or another liquid with residues, you need to rinse the
pump with clear water.
• The submersible pump is equipped with a ventilation
valve to prevent pressure leaks in the pump. Water
entering through the valve can happen but is not a defect.

protected against frost. Otherwise the pump may be
damaged.
