Renfert Dustex master plus Mode D'emploi page 15

1 Introduction
We are pleased with your decision to purchase a Renfert Dustex master plus dust extractor box�
The Dustex master plus is an extraction box fitted with an extraction duct and arm supports for a more
comfortable working position�
Please read the following operating instructions carefully and observe all the information they
contain in order to ensure long and trouble-free service.
The suction box is available in an older version with fluorescent tubes and a current version with
LED lighting.
In the operating instructions the differences are described wherever relevant.
2 Application Area
In dental technology and clinical laboratories as well as similar professional fields (e.g., goldsmiths, model
builders), grinding acrylics, plasters, porcelains, and other materials generates dusts and vapours. The
extraction box reduces the effects of dusts and vapours, thus providing improved protection for the oper-
ator. The large openings on the sides offer great freedom of movement, but it is precisely for this reason
that the extraction box is not suitable for use with blasting units�
2.1 Ambient Conditions (in accordance with DIN EN 61010-1)
The unit may only be operated:
• Indoors;
• Up to an altitude of 2,000 m [6.500 ft] above sea level;
• At an ambient temperature range of 5 - 40 ºC [41 - 104 ºF] *);
• At a maximum relative humidity of 80 % at 31 ºC [87.8 ºF], dropping linearly to 50 % relative humidity at
40 ºC [104 ºF];
• With a mains power supply whose voltage fluctuations do not exceed 10 % of the rated value;
• Under over-voltage category II conditions;
• Under contamination level 2 conditions�
*) Between 5 - 30 ºC [41 - 86 ºF] the unit can be operated at a relative humidity of up to 80 %. At temperatures between 31 - 40 ºC
[87.8 - 104 ºF] the humidity must decrease proportionally in order to ensure proper operability (e.g., at 35 ºC [95 ºF] = 65 % rela-
tive humidity, at 40 ºC [104 ºF] = 50 % relative humidity). The unit may not be operated at temperatures above 40 ºC [104 ºF].
