INTRODUCTION

The safety instructions found in this manual, supplement and replace, where conflict exists, those found in the user and
maintenance manual. The safety instructions refer to the installation, use and maintenance of volumetric pumps protected from
the risk of explosion and intended for use in areas where potentially explosive atmospheres are present.
These instructions are essential for the pump to conform to the requirements of Directive 2014/34/EU and must therefore
be: known, available, understood and used.
The personnel in charge of the installation, inspection and maintenance of the pump must have adequate technical
preparation combined with suitable knowledge of the potentially explosive atmosphere and the risks associated with it.
Any use of the pump beyond the instructions indicated in the user and maintenance manual and in this supplement will
invalidate the requirements concerning safety and protection against the risk of explosion.
The risks associated with the use of the pump in the precise conditions prescribed in the user and maintenance manual
and by the present supplement have been analysed: the analysis of the risks associated with the interface with other
system components is the installer's responsibility.
