WARNING
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 ACUARIA37/57 range consists of vertical
submersible pumps, easy to install and designed to
operate with clean water, free from elements in
suspension, at a maximum temperature of 40°C.
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 cata-logues 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 regula-tion
control that adjusts the pump's operation to the system
performance.
The efficiency reference criteria can be found on the
following link:

A
Warning! Observe limitations of use.
B
The name plate voltage must be the same as the mains voltage.
C
Connect the pump to the mains via an omnipolar switch with at
least a 3 mm opening between contacts.
D
Install a high-sensitivity differential switch (0.03A) as extra
protection against lethal electric shocks.
E
Connect the pump to the ground.
F
Use pump only within performance limits indicated on the name
plate.
G
Be careful with hazardous liquids and environments.
H
Do not carry the pump by the power cable.
I
This apparatus may be used by children older than 8 and persons
with reduced physical, sensory or mental capacities, or lacking
experience and knowledge, if they are supervised or receive
adequate training on the safe use of the apparatus and understand
the dangers.
Children should not be allowed to play with the apparatus.
Children should not perform the ordinary cleaning and maintenance
tasks without supervision.
J
The pump should only be dismantled by authorized personnel.
K
Cut the power supply before servicing the electrical pump.
L
Warning! Avoid icing.
