How to use these operating instructions Before using the centrifuge, read the operating instructions and observe them. The operating instructions are a part of the device. They must always be kept readily available. If the device is set up at a different location, the operating instructions must be provided with it. Symbol meanings Symbol on the device: Attention, general hazard area.
The centrifuge may only be used by skilled personnel in closed laboratories. The centrifuge is only meant for the above-named purposes. Another use or one which goes beyond this, is considered to be non-intended. The company Andreas Hettich GmbH & Co. KG is not liable for damage resulting from this.

Repairs must only be carried out by personnel authorised to do so by the manufacturer. Only original spare parts and original accessories licensed by the Andreas Hettich GmbH & Co. KG company are allowed to be utilised.
Unpacking and setting up the centrifuge Remove the packaging. Remove the front wooden beam (a). Fasten the metal rails (b) to the wooden pallet with two nails each. Push the front wooden beam (a) under the metal rails (b) to support these. Roll the centrifuge carefully down from the wooden pallet using the metal rails (b).
Transport and storage Transport When the device and accessories are transported, the following ambient conditions must be complied with: Ambient temperature: -20°C to +60°C Relative humidity: 20% to 80%, non-condensing Storage The device and the accessories may only be stored in closed and dry rooms. When the device and accessories are stored, the following ambient conditions must be complied with: Ambient temperature: -20°C to +60°C Relative humidity: 20% to 80%, non-condensing...
Interface (only for centrifuge with interface) As an option, the device can be equipped with an optical interface. IOIOI The optical interface is labeled with the symbol. OPTICAL The centrifuge can be controlled and data queried via this interface. Opening and closing the lid 12.1 Opening the lid The lid can only be opened when the centrifuge is switched on and the rotor is at rest.
Loading the rotor Standard centrifuge containers of glass will not stand RCF values exceeding 4000 (DIN 58970, pg. 2). Check the rotor for firm seating. With swing-out rotors all rotor positions must be lined with identical hangers. Certain hangers are marked with the number of the rotor position.
Closing biosafety systems In order to guarantee that it is sealed, the lid to the biosafety system has to be firmly closed. In order to prevent the packing ring from twisting when opening and closing the cover, the packing ring must be lightly rubbed with talcum powder or a rubber care product.
Control and display devices 4000 120:30 STOP LOCK1 16.1 Status symbols Lid open. Lid closed. Rotation indicator. The indication appears while the centrifuge is running as long as the rotor is turning. STOP Centrifugation run stopped or finished. Indication after completion of the centrifugation run as long as the rotor is turning.
1. Start centrifugation run. The rotation indicator appears. START 2. Acceptance of changes during the centrifugation run. Stop centrifugation run. STOP The rotor decelerates with the preset run-down parameters. Pressing the key twice will initiate an emergency stop. Select program location, parameter PROG-Nr. PROG Calling up of programs.
17.4.3 Braking step Press the key repeatedly until the parameter is displayed. The input field will be displayed inversely. Set the desired step by means of the control knob B-braking steps can only be set for special rotors. 17.4.4 Run-down time If a brake de-energisation speed has been set, it is not possible to set a run-down time.
Centrifugation When the centrifuge is running, according to EN / IEC 61010-2-020, no persons, dangerous substances or objects may be within the safety margin of 300 mm around the centrifuge. If the permissible weight difference within the rotor loading has been exceeded, the drive shuts down during the start-up, and IMBALANCE / UNWUCHT is displayed.
Displaying the maximum RCF of the rotor Press the key repeatedly until the parameter RCF/RZB is displayed and the input field is shown inversely. Press the key once more and hold it pressed; the maximum RCF of the rotor (RCF-max-Rotor) will be displayed.
Immediate display of the centrifugation data after switching on Switch on the mains supply switch. Switch position . Press any key apart from the key when the first visual change appears in the display (inverse display). The STOP centrifugation data will be displayed immediately. Key-operated switch.
31.3 Centrifugation run with program linking Press the key twice in order to select the parameter PR-PART. The input field will be displayed inversely. PROG Set the program location for the first program (XX+) by means of the control knob Press the key.
Relative centrifugal force (RCF) The relative centrifugal force (RCF) is given as a multiple of the acceleration of gravity (g). It is a unit-free value and serves to compare the separation and sedimentation performance. These values are calculated using the formula below: 1,118 1000 1000...
Emergency release During a power failure the lid cannot be unlocked by motor. An emergency release has to be executed by hand. For emergency release disconnect the centrifuge from the mains. In the case of permanently connected devices, switch off the mains switch to disconnect the mains supply of the device in the building installation and secure it against being switched on again, e.g.
38.1.2 Surface disinfection If infectious materials penetrates into the centrifugal chamber this is to be disinfected immediately. Ingredients of suitable disinfectants: ethanol, n-propanol, ethyl hexanol, anionic tensides, corrosion inhibitors. After using disinfectants, remove the disinfectant residue by wiping with a damp cloth. The surfaces must be dried immediately after disinfecting.
The rotors and accessories must be dried directly after removing the radioactive contaminants. 38.2.4 Trunnions With swing-out rotors the trunnions must be regularly lubricated (Hettich Lubricating Grease No. 4051) in order to ensure consistent swinging out of the hangers. 38.2.5 Rotors and accessories with limited service lives The use of certain rotors, hangers and accessory parts is limited by time.
38.3 Autoclaving The following accessory can be autoclaved at 121°C / 250°F (20 min): Swing-out rotors Angle rotors made of aluminum Hanger made of metal Lid with biocontainment Stands Reductions Otherwise you must ask the manufacturer. No statement can be made about the degree of sterility. The lids of the rotors and containers must be removed prior to autoclaving.
Faults If the fault cannot be eliminated with the help of the fault table, please inform Customer Service. Please specify the type of centrifuge and the serial number. Both numbers can be found on the name plate of the centrifuge. Perform a MAINS RESET: Switch off the mains switch (switch position "0").
Returning Devices If the device or its accessories are returned to Andreas Hettich GmbH & Co. KG, in order to provide protection for people, the environment and materials, it has to be decontaminated and cleaned before being shipped.
