2. Description
2.1 Usage
•The SLE350 or SLE500 medical compressor, herein after referred to as the
compressor, is the source of clean, oil free pressurized air for use with
respiratory equipment. Due to the silent operation of the compressor, it is
possible to place the unit near the respiratory appliance beside the bed of the
patient.
The compressed air from the compressor is suitable for the operation of
respiratory appliances or similar apparatus.
•The compressor is to be operated in dry, aerated rooms where the ambient
temperature is between +15°C and +40°C, with the relative air humidity not
exceeding 70%.
•The compressor must not be exposed to rain. The appliance must not be used in
humid or wet environments. Furthermore, it is forbidden to use it in the presence
of flammable liquids or gasses.
•Before connecting the compressor to the respiratory device, it is necessary to
assess whether the compressor meets the requirements of the given device.
Please, refer to the technical data for this purpose.
•Usage, other than the compressors intended use is not considered to be safe.
The manufacturer is not responsible for the damages implied if the compressor
is used for other uses. Such a risk is assumed only by operator/user.
