MAINTENANCE AND USE MANUAL

furnace DM

EN

The equipment must rest on non-flammable supports and tops only.
It is strictly forbidden to store any solid, liquid or gaseous flammable substances 
in the vicinity of the equipment.

6.1

WARNINGS AND PRECAUTIONS

CHAPTER 6:   INSTALLATION AND FIRST-TIME USE

So as to provide greater clarity the numbers given in the diagrams in this 
chapter  correspond  exactly  to  the  numbering  in  the  Components  Table 
(Ch. 3).

Work  area  lighting  is  an  important  factor  in  both  personnel  safety  and  the 
ultimate quality of the work being done. In Italy lighting must comply with a 
Ministerial Decree Law that clearly defines minimum lighting requirements. 
In other countries lighting requirements form part of the accident prevention 
and workplace hygiene standards.

Before  proceeding  with  installation  make  sure  that  all  relevant  safety  conditions  prevail  and
follow the instructions below carefully.

6.3

REQUIRED WORK SPACE

Choosing  a  good  workplace  with  an  appropriate  amount  of  space  available  for  equipment 
installation  is  an  essential  factor  in  personnel  safety,  the  quality  of  the  work  and  proper
maintenance.  This  zone  must  not  only  be  spacious  enough  to  allow  for  optimum  equipment
operation but must also be well illuminated, aired, not dusty and not exposed to direct sunlight. 
Note also that the unit must be positioned so the connection plug can be handled/manipulated with 
ease.

6.2

PERMITTED AMBIENT CONDITIONS

Unless stated otherwise at the time of order the equipment will be configured to operate properly 
under the following ambient conditions:

Ambient  conditions  other  than  those  listed  above  may  cause  malfunctions  or  sudden
breakdowns. Lighting in the installation area must be sufficient to provide good visibility at every 
single point on the equipment.
More  specifically,  luminosity  must  not  be  less  than  200  lux,  lighting  must  be  as  uniform  as
possible and there must be no reflected light as this could dazzle the operator.

The equipment must not be used in workplaces having an atmosphere which is 
explosive and/or at risk of fire as it has not been designed for use in such areas. 
Nevertheless, should a fire accidentally break out follow the procedure described 
in paragraph 2.4.

Place of Use

Indoors

Altitude

Up to 2000 m

Working temperature
