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, dryingand heating conditions. Glass, metal and other materials can be sterilized in FN seriesdry heat sterilizers.

They maintain temperatures between ambient temperature + 5 C and 250 C and keepthe temperature stable within the given tolerances.

FN 300/400/500 dry heat sterilizers/ovens provide homogeneous temperature distributionby means of the sheet heaters placed onto three outer surfaces of the useful volume.

Differently from FN 300 / 400 and FN 500, inner sides of FN 400P and FN 500P are

made of stainless steel and their heaters are circular heaters which provide thehomogeneity of the temperature by the circulation fans placed on their centers.

The insulation of the dry heat sterilizers/ovens not only provides economical workingconditions but also helps to achieve the excellent homogeneity.

The FN series dry heat sterilizers/ovens provide precise operation conditions with thePID microprocessor controlled system and with the timer. Adjustable safety thermostatoffers an additional safety.

The FN series dry heat sterilizer/ovens are manufactured according to the followingstandards,

EN 61010-1, EN 60601-1, EN 60601-1-2

Do not operate the instrument for purposes other than main purpose.

The instrument is only to be used by authorized people after the users manual hasbeen read carefully. Only technical personnel can handle the product in case of abreakdown.

3. INSTALLATION PROCEDURE

3.1. Lifting and Transport

Because of the heavy weight of the dry heat sterilizer/oven, all lifting and transport must

be carried out using proper handling equipment. The dry heat sterilizer/oven must besupported from underneath and never turned over.

3.2. Unpacking

Remove the packing cardboard box and the second nylon packing around the dry heatsterilizer. The below written are provided with the instrument, please check them;

Users manual 1 piece electrical cable 2 pieces of shelves 4 pieces of shelf carriers

3.3. Environmental Conditions

Please pay special attention to the followings,

Indoor use only Temperature from 5C to 40 C Humidity level % 80 up to 22 C Maximum height 2000 m. Temperature range for maximum performance: 15C / 25C

3.4. Mains Supply

The dry heat sterilizer/oven requires 230, 50 / 60 Hz.

Please make sure that the supplied mains matches the required power ratings. If no,provide an extra line to support.

Always plug the dry heat sterilizer/oven to properly earthed sockets.

A supply fitted with a circuit breaker should be used for protection against indirectcontact in case of an insulation fault.

3.5. Positioning

Check that no damage has occurred during transport. Lift the dry heat sterilizer/oven underneath and carry it to its place carefully. Balance the dry heat sterilizer/oven on the four pedestals. If necessary, provide stable

standing by adjusting the pedestal heights. Insert the shelf carriers and then the shelves.

Check the followings,

The proposed site is suitable for users, The dry heat sterilizer/oven does not occupy the utilisation space of others or damage

them.

3.6. Prior to Operation

Check the followings,

Make sure that the safety thermostat is adjusted to the temperature which is higherthan the set temperature.

Liquids are not heated in sealed containers. The boiling points of the samples are higher than the set temperature. The freezing points of the samples are lower than the set temperature. The liquids which may expand during heating do not overflow from their containers. The set temperature does not destroy the structure of the samples. The vapours and gases which are generated during the operation are not harmful to

human health or flammable or explosive.
