Operating environment

Note the following points so that the instrument will operate correctly and
have a long service life.
• Place the instrument firmly on an even surface. Do not push any
objects under the instrument.
• The ambient temperature must be 5 to 40 °C (41 to 104 °F).
• The relative humidity should be less than 80%; moisture should not
condense on the instrument.
• A minimum clearance of 15 cm (5.9 in.) must be ensured above and
on all sides of the device; this allows the air to circulate and
prevents overheating of the electric parts. The dosage arm of the
stepper motor operating the syringe piston must be able to move
freely.
• Do not operate or store the instrument in extremely dusty, humid or
wet locations.
• Make sure that no liquids enter the instrument and immediately wipe
away any liquids that contact the instrument.
• Protect the instrument against vibrations, direct sunlight, corrosive
gases as well as strong magnetic and/or electric fields.
• Only use genuine replacement parts and accessories.
• The instrument must be serviced by the manufacturer's service
department at the prescribed intervals.
