EN
The following information is intended to assist you,
the operator, in safely working with the Magma pre-
heating oven in your laboratory.
Using these operating instructions as a
starting point, instruct all operators of the
unit with regard to the area of application,
the possible hazards during operation,
and the proper operation of the preheating
oven.
Please have these operating instructions readily
available for the operators.
A. Application Area

A.1 Proper Use

The Magma preheating oven is solely intended for
use in dental technology laboratories as well as arts
and crafts and jewellery workshops. The preheating
oven is solely intended for waxing up and preheating
casting dies. Only modelling waxes and modelling
plastics may be employed as modelling materials.
Only specialist personnel may operate the unit as
incorrect operation can result in extreme deterioration
in the quality of individual pieces and may also pres-
ent extreme hazards to the operator.

A.2 Improper Use

Modelling waxes and modelling plastics MAY NOT be
placed directly in the oven without being embedded in
a casting die.
Only spare parts and accessories supplied or autho-
rized by Renfert GmbH may be used with this prod-
uct. If other spare parts or accessories are used, this
could have a detrimental effect on the safety of the
device, increase the risk of serious injury and lead to
damage to the environment or the device itself.

A.3 Setup

The preheating oven is solely designed to be used
under an extractor or extraction hood.
The extraction equipment must comply with all local
ordinances and regulations.
The extraction equipment must be dimensioned on
the basis of the materials being processed and the
eventual emissions of other devices.
No vapours may escape into the room atmosphere.
Depending on the types of vapours produced, it may
be necessary to obtain approval from the appropriate
local authorities for the operation of the extraction
equipment.
The hazardous emissions generated by the oven
can be significantly reduced by the employment of a
ctalyst converter (optional accessory).

Information for Operators

A.4 Ambient Conditions

(in accordance with DIN EN 61010-1)

The unit may only be operated:
• Indoors;
• Up to an altitude of 2,000 m above sea level;
• At an ambient temperature range between 5 - 40 ºC
[41 - 104 ºF] *);
• At a maximum relative humidity of 80 % at 31 ºC
[87.8ºF], dropping in a linear manner to 50 % rela-
tive humidity at 40 ºC [104 ºF] *);
• With mains power where the voltage fluctuations do
not exceed 10 % of the nominal value;
• Under contamination level 2 conditions;
• Under over-voltage category II conditions.
*) Between 5 – 30 °C [41 – 86 °F], the unit can be operated at
a relative humidity of up to 80 %. At temperatures between
31 – 40 °C [87.8 – 104 °F], the humidity must decrease
proportionally in order to ensure operational readiness (e.g.,
at 35 °C [95 °F] = 65 % humidity; at 40 °C [104 °F] = 50 %
humidity). The unit may not be operated at temperatures above
40 °C [104 °F].
A.5 Ambient Conditions for
Storage and Shipping
The following ambient conditions must be maintained
during storage and shipping:
• Ambient temperature: -20 – +60 ºC [-4 – +140 ºF],
• Maximum relative humidity: 80 %.
B. Hazard and Warning
Information
Only intended for indoor use. The unit is
only designed for dry applications and may
not be operated or stored outdoors or un-
der wet conditions.
The unit may not be taken into service until
any required alterations to comply with re-
gionally specific power plug configurations
have been made. Such alterations may only
be performed by a qualified electrician.
The unit may only be operated if the infor-
mation on the nameplate conforms with the
specifications of your local mains power
supply.
The unit may only be plugged into an outlet
which is connected to a ground wire sys-
tem.
Regularly inspect connecting lines and hos-
es (e.g., the power cord) for damage (e.g.,
kinks, cracks, porosity) or signs of aging.
Units exhibiting damaged connecting lines,
hoses, or other defects must be taken out
of service immediately.
