indispensable, it is necessary to use only products that comply with current safety standards, respecting the flow
limit in current value and maximum power.
Pipe connection: the pipes must be rigid and reinforced, and must be fixed to the pump by means of special
clamps, avoiding the formation of bottlenecks that could prevent the regular flow of the liquid.
IMPORTANT: never start the machine when empty (in the absence of liquid). The first time the machine is
started, it is necessary to carry out a preliminary washing in order to remove any manufacturing remains.
The EURO self-priming electric pumps are driven by an electric motor (made in compliance with all current safety
regulations), whose switch, when the machine is off, must always be positioned on the "central zero".
To start, the switch must be set to the desired speed, or to position "1" for models with only one speed. The mouth
of the pump which will suck the liquid is determined by the direction of rotation of the impeller, which can be
controlled by observing the rotation of the van on the back of the engine.
STARTING:
the starting mode varies according to the model purchased.
SINGLE PHASE COAXIAL MODELS:
On this type of pump, the electrical panel is equipped with a double condenser: one for commissioning (standard
on all single-phase motors) and a special boost condenser to guarantee additional power during start-up.
In addition to the "0" stop position, the rotation inverter also presents position 1 (clockwise rotation), position 2
(counter clockwise rotation) and position with AVV spring start, indicated both after number 1 and number 2.
To start the machine, turn the switch in the required direction for 2 seconds in the AVV position, which must be
released as soon as the pump starts running.
CAUTION: Do not insert the switch in the AVV position, otherwise you risk damaging the internal boost
condenser. FOR THE EURO 20 MODEL an electric solution is provided.
The AVV position is not present, but after the pump has been stopped, it needs to wait for 5 seconds before a new
start.
If the pump is supplied with automatic stop and start systems (for example pressure switch or flow switch), in
single-phase coaxial versions, it is not possible to invert the direction of rotation (except for the EURO 20 model).
