A different use or application over and above this is deemed not in accordance with the specifications. The company Andreas Hettich GmbH & Co. KG undertakes no liability for damages resulting therefrom. Belonging to the application according to specification is also the observance of all references contained in the Instruction Manual and compliance with the inspection and maintenance works.
The centrifuge may no longer be put into operation when the centrifuging chamber has safety- related damages. • 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. •...

• 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. •...
Symbol meanings Symbol on the machine: Attention, general hazard area. Before using the centrifuge implicitly read the operating instructions and pay attention to the safety relevant references! Symbol in this document: Attention, general hazard area. This symbol refers to safety relevant warnings and indicates possibly dangerous situations. The non-adherence to these warnings can lead to material damage and injury to personal.
Initial operation • According to the laboratory instrument standards EN / IEC 61010-2-020 an emergency switch to separate power supply in the event of a failure must be installed in the building electrical system. This switch has to be placed remote from the centrifuge, preferred outside of the room in which the centrifuge is installed or near by the exit of this room.
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.
12.2 Control knob For setting the individual parameters. Turning anticlockwise reduces the value. Turning clockwise increases the value. 12.3 Keys and set-up options Running time, parameter t/min:sec Parameter t/min: Adjustable from 1 - 999 min, in 1 min steps. Parameter t/ :sec Adjustable from 1 - 59 s, in 1 second steps. Continuous running "---:--"...
Entering centrifugation parameters It is only possible to enter a parameter when the input field is displayed inversely (dark background). An inverse input field will go off automatically after 10 seconds. 13.1 Running time 13.1.1 Time selection • Press the key repeatedly until the parameter t/min: or t/ :sec is displayed.
13.4.5 Brake de-energisation speed (•) • Press the key repeatedly until the parameter n /RPM is displayed. The input field will be displayed inversely. • Set the desired value by means of the control knob 13.5 Radius • Press the key repeatedly until the parameter r/mm is displayed and the input field is shown inversely.
15.2 Continuous running • Select the ---:-- symbol or call up a continuous running program (see Chapter "Entering centrifugation parameters" or "Calling up programs"). • Press the key. The rotation indicator will appear as long as the rotor is turning. The time count starts START from 00:00.
Interrogating the operating hours It is only possible to interrogate the operating hours when the rotor is at standstill. • Open the lid. • Press and hold the key for 8 seconds. After 8 seconds SOUND / BELL XXX will be displayed. •...
Program linking (for centrifuges with program linking only). Several centrifugation runs can be linked together with the help of the program linking function. 27.1 Linking programs Program linking is only possible with programs in which run-up and braking steps have been set. Before linking, the programs must be stored in the desired sequence either by entering the program or by calling up the program (see Chapter "Programming").
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: ⎛...
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. Open the lid only during rotor standstill. See figure on page 2. •...
The rotors and accessories must be dried directly after removing the radioactive contaminants. 32.2.4 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. 21/35...
32.2.5 Rotors and accessories with limited service lives The use of certain rotors, hangers and accessory parts is limited by time. These are marked with the maximum permitted number of operating cycles or with an expiration date and the maximum permitted number of operating cycles or just with the expiration date; e.g.: - "einsetzbar bis Ende: Ι...
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: −...
Acceptance of the centrifuges for repair If the centrifuge is returned to the manufacturer for repair, it must be decontaminated and cleaned to protect persons, environment and material. We reserve the right to accept contaminated centrifuges. Costs incurred for cleaning and disinfection are to be charged to the customer. We ask for your understanding in this matter.
