use and maintenance booklet - safety instructions
If the electric connection is a three-phase connection, make sure the rotation direction is correct. Hold the pump by the handle, lifting it a few
millimetres off the floor, then run the motor for one second. You should notice an anticlockwise reaction. If the pump is rotating in the wrong
direction, simply invert two of the phases.
1.9 Residual risks
The risks that cannot be eliminated by the safety measure adopted by the manufacturer are caused by incorrect use of the pump or by the
user’s failure to comply with the safety regulations described in this manual. In particular, the user must ensure no people and/or animals
come into contact with the fluid when the pump is working.
1.10 Maintenance
The pump maintenance and repair operations must be carried out by workers authorised by the manufacturer; Failure to comply with these
instructions will result in forfeiture of the warranty and jeopardise the unit’s safety. Before any cleaning and/ or maintenance operations are
carried out on the electric pump, the power supply must be switched.
To disconnect the submersible electric pump from the electricity mains, first disconnect the phase conductors, then the yellow –green earth
one.
Use the special handle to remove the submersible electric pump from the tank.
WARNING:
Before carrying out any operations, check the pump temperature. Only work on the pump when it is at room temperature.
Clean the electric pump thoroughly, using a jet of water or specific products to clean all its parts.
When disposing of the waste material, follow the antipollution rules in force.
Replace any broken or worn parts with original spare parts only.
Given the likelihood that work on the electric pump will be carried out in confined spaces such as vats, wells, cesspools, tanks or cisterns, do
not underestimate the risks caused by potentially poisonous exhalations.
Store the electric pump in a suitable place, out of reach of children and unauthorised persons.
Dispatch the electric pump to an authorised scrapping centre for its disposal.
Do not dump any parts of the electric pump.
2. SAFETY INSTRUCTIONS - Blue Standard and PROfessional series - Non sparking apparatus
2.1 Introduction
These safety instructions refer to the installation, operation and maintenance of the pump IECEx and ATEX Blue Standard and Professional
Series for use in areas where there is a presence of potentially explosive atmospheres.
This document treats various safety aspects that involve pumps different constructive variants.
2.1.1 Group II apparatus for gas
The non sparking apparatus IECEx and ATEX Blue pumps have the following protection types against the risk of explosion, the first one
concern pumps without thermal protection and the second one concern pump with thermal protection inside:
II 3G
Ex nA nC IIC T3 Gc
Ex h IIC T3 Gc
II 3G
Ex nA IIC T3 Gc
Ex h IIC T3 Gc
according to
IECEx scheme compliance with the standards:
IEC 60079-0:2011, IEC 60079-15:2010,
and ATEX scheme compliance with the standards:
EN 60079-0:2012+A11:2013, EN 60079-15:2010, EN ISO 80079-36 2016, EN ISO 80079-37: 2016.
2.2 Identification of non sparking apparatus
2.2.1 Suitability of the pump to the location of installation
The user shall check that pump is suitable to the area classification and to the characteristics of the flammable substances present.
National Law, local Rules and Standards establish the essential safety requirements against the risk of explosion in classified areas.
2.2.2 Places subject to the presence of inflammable gas, mist or steam
The classification criteria for areas subject to the risk of explosion are laid down in the IEC 60079-10 standard.
The technical requirements for electrical plants located in classified areas are established by the IEC 60079-14 standard.
The choice of type of pump, according to these technical and legislative provisions, must take into account the following factors:
•
Type of plant: above ground plants
•
Zone classification: 0, 1, 2
•
Characteristics of the flammable substances present in the form of gases, vapours or mists:
-
Sub-group: IIA, IIB, IIC
-
Temperature class: T3 (defines the ignition temperature of the gases)
2.3 Nameplate safety data
In addition to operating data, the information provided on the nameplate, includes:
•
Information necessary to identify the appropriate type of pump and for the correct installation of the pump itself.
•
References to the notified bodies responsible for certification.
