  • Page 10: Intended Use Of The Instrument

    1.4 General safety warnings Use only chemical reagents and accessories specified and supplied by HUMAN and/or mentioned in this manual. Place the product so that it has proper ventilation. The instrument should be installed on a stationary flat working surface, free from vibrations.

  • Page 11: Disposal Management Concept

    1.6 Instrument disinfection Analytical instruments for in vitro diagnostic involve the handling of human samples and controls which should be considered at least potentially infec- tious. Therefore every part and accessory of the respective instrument which may have come into contact with such samples must equally be considered as potentially infectious.

    1.7 Biohazard warning Analytical instruments for in vitro diagnostic application involve the handling of human samples and controls which should be considered at least potentially in- fectious. Therefore every part and accessory of the respective instrument which may have come into contact with such samples must equally be considered as potentially infectious.

  • Page 13: Main Purpose Of The Unit And Description

    Different types of rotors, swing-out and angle rotors, can be fitted to the centrifuges. The microprocessor control system also displays the RCF value during the run. The ventilation system of the HuMax 14K limits temperature in the bowl at max. +12°C. The centrifuges are manufactured according to the following standards:...

    The centrifuge should be lifted from underneath and never be turned over. 4.2 Contents Of Package The package includes: 1 ea. HuMax 14K Centrifuge 1 ea. User manual 1 ea. Manual lid opening tool 1 ea. Electrical cable 1 ea.

  • Page 20: Positioning

    4.5 Positioning Make sure that no damage has occurred during transport. Make sure that the positioning is suitable for users. Lift the centrifuge underneath and carry it to its place. The bench-top must be rigid enough to support the weight and vibrations. Leave 30 cm free space on all sides of the centrifuge.

  • Page 21: Rotor Installation

    InStaLLatIon ProceDure 4.7.1 Rotor Installation Put some light oil on the drive head to prevent sticking. Be careful that the rotor fits on the drive shaft. Screw the shaft nut with socket wrench to the clockwise direction. Make sure that the shaft nut is screwed down tightly, but do not apply excessive torque.
  • Page 22 Imbalance of the rotor may cause major damage to the rotor and centrifuge. Never attempt to introduce liquids into the tube inserts. Balance the rotor with glass tubes if you use glass tubes for centrif- ugation. Balance the rotor with plastic tubes if you use plastic tubes for centrifugation.

    At the end of the cooling operation with the HuMax 14K centrifuges, dry with a non-wool soft cloth or paper towel at the centrifuge cell. (When the end of cooling operation with HuMax 14K, has a puddle at the centrifuge cell. So dry to water with paper towel and soft cloth.)

  • Page 28: Safety Interlock System

    5.5 SAFETY INTERLOCK SYSTEM The safety interlock system prevents opening of the lid when the rotor is spin- ning. The centrifuge does not operate until the lid is closed and the lid remains locked until the rotor stops spinning. The “Lid Open” indicator turns on to warn the user if the lid is not closed properly.

    cLeanInG & PerIoDIcaL MaIntenance 6 CLEANING & PERIODICAL MAINTENANCE 6.1 Periodical Maintenance Disconnect the power cable and after the maintenance check the presence of the mains grounding line. Rotors should be washed after every use, especially if a spillage has occurred, in warm water containing a few drops of liquid soap.

  • Page 30: Corrosion Information

    6.3 Corrosion Information The HuMax rotors which are made of aluminum are designed to spin at prop- er RCF’s for many years. When used properly, their resistance to corrosion and their life span increases and the imbalance problems decrease. All accessories should be thoroughly checked regularly as almost all laboratory environments can easily lead to corrosion.

  • Page 31: Cleaning

    cLeanInG & PerIoDIcaL MaIntenance Every centrifugation causes the aluminium rotor to be attacked by the chemical more and more and eventually micro-cracks decrease the resistance of the ro- tor against the centrifugation force. Fortunately, no crash occurs just after the first micro-cracks have occurred as the rotors are manufactured according to the high safety limits.
