The temperature of the fluid being pumped must never exceed 95
°
C
The pump must not be used to pump salt water, sewage, flammable, 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.

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 frequency specified on the pump’s nameplate coincide with those of the
available 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 of flooding;
•
The electric system is complete with a residual current circuit-breaker (l An S 30 mA) and an
efficient earthing connection;
•
Any extension cords must comply with the requirements for electric safety.
Fill the pump casing and suction hose with clean water before starting the pump for the first
time. If the pump is installed above the water level, filling must be performed slowly until the
water overflows; wait a few 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 filler cap. The pump will fill with water independently.
Plug the pump into the socket, start the pump and wait for the water to exit. If water has not
exited within 2-3 minutes from when the pump was switched on, turn the pump off and repeat
the filling 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 12 inches below the minimum water level.
•
The pump will draw water only when the suction hose is completely filled 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"
