Dustex master / Dustex master plus
ENGLISH
1. Introduction
We are pleased with your decision to purchase a
Renfert Dustex Master or Dustex Master plus dust
extractor box.
The Dustex Master and Dustex Master plus are two
versions of the same dust extractor box. The Dustex
Master is equipped with a base grate while, in the
Dustex Master plus, this grating is replaced by an
extractor duct.
A Dustex master extraction box can be retrofitted
with an extraction duct at any time, please refer to the
section, „Installing the Extraction Duct „.
Please read the following operating in-
structions carefully and observe all the
information they contain in order to ensure
long and trouble-free service.
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 ex-
traction box reduces the effects of dusts and vapours,
thus providing improved protection for the operator.
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 - 40ºC
[41 - 104ºF] *);
• At a maximum relative humidity of 80% at
31ºC [87.8ºF], dropping linearly to 50% relative
humidity at 40ºC [104ºF];
• 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 - 30ºC [41 - 86ºF] the unit can be operated at a
relative humidity of up to 80%. At temperatures between 31
- 40ºC [87.8 - 104ºF] the humidity must decrease proportionally
in order to ensure proper operability (e.g., at 35ºC [95ºF] = 65%
relative humidity, at 40ºC [104ºF] = 50% relative humidity). The
unit may not be operated at temperatures above 40ºC [104ºF].

3.2 Hazard Information
The dust extractor cabinet is an electric unit
and, as such, carries with it a certain inherent
potential electrical hazard.
• The unit may not be operated until it has been
modified to comply with the local electrical
connection requirements. The necessary
alterations may only be performed by a
qualified electrician.
• The unit may only be operated if the
information on the nameplate conforms with
the specifications of your local mains power
supply.
• Never operate the dust extractor cabinet
without an appropriate extraction system
or suitable personal protective clothing, as
operating the unit without proper extraction
will not provide adequate protection against
dusts and vapours which may be hazardous to
your health. The type of extraction employed
must be appropriate to the dusts and vapours
generated during processing. In this regard,
please note the requirements of EN 60335-2-
69, Attachment AA, or ask your professional
organization or regional authority.
Wear eye protection.
