SAfeTy INSTruCTIoNS
For use in environments with danger of explosion.
INTRODUCTION
These safety instructions refer to the installation, use and
maintenance of the equipment for use in areas with presence of
potentially explosive atmospheres.
The equipment that these instructions refer to is equipped with
the following protections against the risk of explosion:
II 2G II B T5
NOTE
These instructions must be complied with in addition to the
general safety warnings previously given.
INSTALLATIoN
Suitability of the equipment for the place of installation.
If it is used in areas with danger of explosion, you have to verify
that the equipment is suitable for the area's classification and for
the characteristics of the flammable substances present on the
plant.
The essential safety requirements to prevent risk of explosion in
the classified areas are set out in European directives 94/9/EC of
23 March 1994 (regarding the equipment) and 1999/92/EC of 16
December 1999 (regarding the plants).
The criteria for classifying the areas with risk of explosion are
given in the EN 60079-10-1 standard.
The technical requisites of the electric installations in the
classified areas are given in the EN 60079-14 standard.
Based on these technical and legislative provisions, the choice of
the type of equipment must consider the following factors:
- type of plant: mine (group I), surface plants (group II)
- classification of the area: 0, 1, 2 (for which, equipment of
categories 1, 2 and 3, respectively, are suitable)
- characteristics of the flammable substances present in the form
of gas, vapours or mists
- temperature classes: T1, T2, T3, T4, T5, T6 (defines the ignition
temperature of the gases)

EARTHING
The equipment must be put to earth by mechanic fixing
(supporting bracket or fluid manifold), paying attention that this
connection is not subject to loosening or unscrewing.
Avoid all electrostatic charges on connecting pipes, using a pipe in
conductive material where necessary.
EXOTHERMIC REACTIONS
Fluids incompatible with the equipment's materials or particularly
reactive mixtures of products with several components may cause
exothermic reactions and develop dangerous temperatures or
pressure. Also check the chemical compatibility of the fluid and
materials.
wArNING
Ignition temperature of the coating material.
The maximum surface temperature of the gun depends
essentially on the temperature of the coating material. The gun is
suitable for coating materials with a maximum temperature as in
the technical data table. The ignition temperature of the coating
material must be at least 15K above the working temperature.
Permissible ambient temperature
Contact with steel or rusty iron.
Mechanical sparks are a source of ignition , which must be
avoided (impacts, blows). Contact with steel or rusty iron, and
working with tools, particularly steel ones, is only permissible if
no explosive atmosphere is present.
Cleaning to maintain the conductive surface.
An essential part of the explosion protection is the continuous
conductivity of the gun. So clean after every use. Surface deposits,
which reduce the conductivity, have to be removed.
