Silent Series Rev 01 03-2020

 

 

 
Thank you for purchasing a SILENT electrocompressor, a choice that reflects your technical knowledge 
and ability to appreciate quality products. 
 
Our compressors are made using high quality materials. They are controlled during the various stages of 
production in line with ISO 9001 quality certification and undergo a series of tests to ensure compliance 
with performance specifications. 
 
This electro-compressor is safe and versatile. Long service life is guaranteed, subject to compliance 
with these instructions for use and maintenance, which satisfy the requirements of Machinery Directive 
2006/42/EEC, implemented in Italy by Presidential Decree 81/08. 
 
If the compressor is not used in accordance with these instructions, operation may be impaired and 
the guarantee will become void. In that case we decline responsibility for any damage that may be 
caused to people, animals or things in connection therewith. 
 
This handbook addresses those who purchase our silent compressors for use in professional 
applications. It contains all the necessary product data and instructions for installation, safe use and 
maintenance. 
 
Read these instructions carefully and keep them for future reference. Compliance with all that set forth 
herein is an essential prerequisite in order to guarantee safety. Regular maintenance and ongoing care 
and inspections are essential in order to guarantee correct operation, efficiency and long service life. 
The user is responsible for duly recording all operations to service the compressor, oil consumption 
values, routine and extraordinary maintenance operations and for ensuring strict compliance with that 
set forth in this handbook. 
 
The compressors described in this handbook are built to satisfy the requirements of Legislative Decree 
81/08 and the applicable technical standards pursuant to the CE declaration of conformity attached 
hereto, and thus conform to all European safety requirements. 
 
The following pages contain all the information and explanations that are necessary in order to guarantee 
correct operation and maintenance. They also provide instructions for implementing the compressed air 
system. Should you require any additional information, please do not hesitate to contact our technicians. 
 
According to current legislation, any modifications to safety devices, unless previously authorised by the 
manufacturer, will immediately render the guarantee void and the user will be held responsible for any 
damage to third parties that may be caused in connection with said modifications. 
 
The manufacturer hereby declines all civil and criminal liability for any damage or injuries that may be 
caused as a result of non-compliance with that set forth in this handbook.

 

 

 

WARNING 
 
These instructions for use and maintenance constitute an integral part of the compressor and must be 
kept in the vicinity of the equipment or by the personnel responsible for using the equipment.
