The temperature othe fuid being pumped must never exceed 35° C.
The pump must not be used to pump salt water, sewage, fammable, corrosive or explosive liquids
(e.g. petroleum oil, petrol, and thinners), grease, oils or foodstuffs.
Comply with the rules and regulations of the local water authority when using the pump for the
supply of domestic water.
3. STARTING THE PUMP
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.
Before starting the pump, make sure that:
•the voltage and requency specied on the pump’s nameplate coincide with those othe avai
lable power supply;
• there are no signs of damage to the pump or its power cord;
•the electric connection is made in a dry place, protected against any risk ofooding;
• the electric system is complete with a residual current circuit-breaker (I ∆n≤30 mA) and an
ecient earthing connection;
•any extension cords must comply with the requirements or electric saety.
Fill the pump casing and suction hose with clean water beore starting the pump or the rst time.
Ithe pump is installed above the water level, lling must be perormed slowly until the water
overfows; wait a ew seconds to make sure that all the air has escaped and top up until the level
has stabilised.
If the pump is installed below the water level (below head), bleed the air from the pump casing by
opening the ller cap. The pump will ll with water independently.
Plug the pump into the socket, start the pump and wait or the water to exit. Iwater has not exited
within 2-3 minutes rom when the pump was switched on, turn the pump o and repeat the lling
operation again.
Attaching the suction hose
• Fit the suction hose from the water source to the pump making sure that the pump is above the
• water level. Do not position the suction hose above the level of the pump (to avoid air bubbles forming in
• the suction hose).
• The suction hose should be mounted in such a way that it does not create any mechanical stress on the
• pump.
• The foot valve should be placed at least 30 cm below the minimum water level.
•The pump will draw water only when the suction hose is completely lled with water.
• The suction hose and the pump’s suction inlet should be of the same diameter.
Attaching the delivery hose
• To get the best performance from the pump, it is recommended that the diameter of the delivery hose is at least 1”
• During the self-priming phase, all taps, valves, etc. on the delivery hose must be fully open in order to allow
the air inside the hose to escape.
Beore plugging in and starting the pump or the rst time, it is necessary that the suction hose and the pump
are completely lled with water in order or suction to take place. For use in wells or when the water level is
lower than the pump, a suction hose must be used that is equipped with the foot valve. This will allow the
suction hose to remain lled with water ater the rst time that it is lled and will prevent the emptying othe
hose when the pump shuts off automatically, avoiding any problems when restarting.
