1. GENERAL INFORMATION
Please observe the following instructions to achieve
the best pump performance possible and a trouble
free installation.
Read these instructions before installing the
pump. Save them for future reference.
The
ACUARIA
range
submersible pumps, easy to install and designed to
operate with clean water, free from elements in
suspension, at a maximum temperature of 40°C.
The lubricating oil in the motor is non toxic. In the case of
accidental discharge, it will not affect the colour or smell
of the water and has no detrimental health effects.
Correct pump operation is assured providing
the instructions on electrical connection,
installation and use are strictly adhered to.
Failure to adhere to the instructions can
result in premature failure of the pump and
voiding of the warranty.

Minimum efficiency index
With the application of the European Regulation
547/2012, the minimum efficiency index after
01/01/2015 must be MEI ≥ 0.40.
The reference value for the most efficient hydraulic
pumps is rated at MEI ≥ 0.70.
The performance curves and efficiency characteristics
can be checked on the technical catalogues and on
www.espa.com.
The operation of this hydraulic pump with variable
operating points can be cheaper and more efficient
when controlled with, for example, a speed
regulation control that adjusts the pump's operation
to the system performance.
The efficiency reference criteria can be found on the
following link:

2. HANDLING
The pumps are supplied suitably packaged to prevent
damage in transit. Before unpacking, check that the
packaging has not been damaged or deformed,
Lift and handle the product with care and with
the right tools.
3. INSTALLATION
Pumps should not rest on the bottom of the
well, nor be placed very near the walls. To
avoid this, hang the pump from a cable
through the handle on the top.
Never hang the pump from the power cable
or the discharge line. The pump must be
completely submerged to ensure proper
cooling. See fig.1.
Make sure the well flow is higher than required,
to prevent the pump from running dry or from
starting and stopping more often than normal.
If the well water level fluctuates significantly,
we recommend installing level electroprobe
equipment.
To avoid ruining the motor power cable and
level electroprobe cables, attach them to the
discharge line with clamps when lowering
them into the well.
3.1. Discharge pipe assembly
The pumps are supplied ready to be connected a 1"
line.
However,
if
considerable and the paths are long and winding,
we recommend using lines with a larger diameter,
to avoid head loss due to friction as much as
possible
and
to
performance possible.
Install a check valve on the outlet of the pump to prevent
the line from emptying every time the pump stops.
If a plastic hose is chosen instead of a metallic line,
make sure it can withstand the pressure provided
by the pump. Prevent the hose from becoming
twisted because, in addition to preventing the
