SECTION 1
INTRODUCTION
1.1 USE AND FUNCTION
The FN Series Dry Heat Sterilizers/Ovens are designed to sterilize metal and glass materials and
heat or dry samples in laboratories. They offer excellent sterilization, drying and heating conditions.
Glass, metal and other materials can be sterilized in FN Series Dry Heat Sterilizers.
They maintain temperatures between 70°C and 250°C and keep the temperature stable within the
given tolerances.
FN 300/400/500 Dry Heat Sterilizers/Ovens provide homogeneous temperature distribution by
means of the sheet heaters placed onto three outer surfaces of the useful volume.
Differently from FN 300/400/500, inner sides of FN 400P and FN 500P are made of stainless steel
and their heaters are circular heaters which provide the homogeneity of the temperature by the
circulation fans placed on their centers.
The insulation of the Dry Heat Sterilizers/Ovens not only provides economical working conditions
but also helps to achieve the excellent homogeneity.
The FN series Dry Heat Sterilizers/Ovens provide precise operation conditions with the PID
microprocessor controlled system and with the timer. Adjustable safety thermostat offers an
additional safety.
Microprocessor control system will shut down the temperature sensor and in case of malfunctions
that may occur in the control system, alarm system will be activated and the user is warned visually
and audibly. The study data are recorded in the memory and can be transferred to external USB
memory. At the same time, unauthorized persons have been blocked permission to change
parameters with improved password menu.
The FN series dry heat sterilizer/ovens are manufactured according to the following standards,
ISO 9001:2015, ISO 13485:2016, EN ISO 14971:2012, MDD 93 / 42 / EEC (2007/47/EC), EN
60601 –1, EN 60601 –1 –2, EN 60601 –1 –6, EN 62304, EN ISO 15223 –1, EN 61000–6–3,
EN 62366 –1, EN 50419.
This device is in compliance with WEEE Regulation.
Do not operate the instrument for purposes other than main purpose.
The instrument is only to be used by authorized people after the user’s manual has been
read carefully. Only technical personnel can handle the product in case of a breakdown.
