.
The pump must not be used to pump salt water (unless specifically designed for the purpose),
sewage (except for submersible pumps suitable for pumping dirty water with solid particles
having a maximum diameter of 38 mm), flammable, corrosive or explosive liquids (e.g.
petroleum oil, petrol, thinners), grease, oils or foodstuffs.
Comply with the rules and regulations of the local water authority when using the pump for the

3. STARTING THE PUMP
Before starting the pump, make sure that:
x
the voltage and frequency specified on the pump’s nameplate coincide with those of the available power
supply;
x
there are no signs of damage to the pump or its power cord;
x
the electric connection is made in a dry place, protected against any risk of flooding;
x
the electric system is complete with a residual current circuit-breaker (I
¨
n
30 mA) and an efficient
earthing connection;
x
Any extension cords must comply with the requirements of the DIN VDE standard 0620.
Note
: given the different provisions applicable to the safety of electric systems in different countries,
make sure that the pump system, as concerns its intended use, is in accordance with current legislation.
Insert the plug of the power cable into a suitable power socket.
Automatic operation:
The floating switch starts and stops the pump automatically.
The water level that prompts the starting and stopping of the pump can be adjusted by changing the length of
cable of the float between the holder and the float.
N.B. The length of the float cable must never be shorter than 10 cm.
Manual operation:
a)
The floating switch must be lifted in order to start pumps with a float.
b)
For pumps without a float, insert the plug.
4. RECOMMENDATIONS
To ensure the proper operation of the pump, it is important to comply with the following recommendations:
x
The pump must never be allowed to run dry.
x
Never leave the pump in operation when the delivery pipe is clogged.
x
The pump must only be used when it is immersed in water. If the water runs out, the pump must be
stopped immediately by removing the plug from the power supply.
x
Pay careful attention when the pump is operated in manual mode.
x
The pump must be placed in a stable position inside a trap or in the lowest part of the place where it is
installed.
x
The float must be able to move freely while the pump is running therefore the advised dimensions of the
trap are 40x40 cm.
Available in an automatic version with fl oat switch for automatic starting and stopping of the pump.
