1.General Information
1.1Precautions and hazards
Before putting the centrifuge into operation, please read this instruction manual carefully.
The centrifuge must not be operated by unqualified persons not familar with the correct use and intended purpose of the machine. Please use only the original spare parts.
For personal and enviromental safety, special attention has to be paid to the following precautions:
The Hermle Centrifuges are neither explosion proof nor inert gas shielded and should therefore never be operated in explosion-hazardais locations.
Never stay in the safety zone of 30 cm around the centrifuge or deposite dangerous goods inside this zone during centrifugation.
The centrifugation of the flammable or explosive or radioactive samples is not allowed.
Further more do not spin samples reacting chemically with each other with high energy when explosed to air.
Never spin toxical or phatological material without adequate safety precautions i.e. centrifuging of buckets/tubes without or with defective hermetic sealing is not allowed.
The enduser is engaged to performe appropriate disinfection procedures in case dangerous goods have contaminated the centrifuge or its accessories.
The general universal laboratory precautions should be observed in case infection materials are centrifuged. If necessary, please contact your local security officer!
It is prohibited to run the centrifuge with rotors not suited for this centrifuge model. Under no circumstances, the lid at the centrifuge should be opened while the rotor is still turning respectively running with a speed of more than 2 meter per second.
The following rules must be strictly adhered to:
Do not operate the centrifuge in case it is not installed correctly.
Never operate the centrifuge in a dismounted state (e.g. without covering sheet metal)
Do not run the centrifuge when electrical or mechanical assembly groups have been tampered with by unauthorized persons.
Never use accessories such as rotors and buckets which are not exclusively approved by Hermle Labortechnik GmbH, except commercially available centrifuge tubes of glas or plastic.
Do not spin corrosive samples which may cause damages in material and impair the mechanic resistance.
never operate the centrifuge with rotors or buckets which show any signs of corrosion or mechanical damage
The manufacturer is only responsible for the security and reliability of the centrifuge if:
The unit is operated according to the instruction manual.
Modifications, repairs and new adjustments are performed by HERMLE authorized persons and the electrical installation of the location where the centrifuge is operated corresponds to the IEC-regulations.

1.2Description
The Z 400 K is a refigerated universal centrifuge which covers many fields of applications by offering a wide range of accessories.
The centrifuges are equipped with the Hermle Standart-Control panel.
Speed, RCF - value, running time and temperature are set with easy to use control knobs.
The precise parameters selected are shown on the large digital LED display. The refigeration system is CFC free.
By offering a wide range of accessories, the centrifuge covers many fields of applications.
1.3Safety standards
The centrifuge corresponds to the general requirements set by German law for medical apparatus, "MedGV" group 3.
The following standards have been considered for the production of our centrifuges:
-Accident prevention rules for centrifuges, UVV-VBG 7z.
-Accident prevention rules for electrical equipment & installations, UVV-VBG 4.
-Accident prevention rules for cooling systeme, UVV-VBG 20
-International Standart IEC 1010-1 and IEC 1001-2-D
-European Standart PR EN 61010-1 and PR EN 61010-2-2
-Electrical interference suppression according to interference degree B as per VDE 0871.

1.5Accessories supplied with each centrifuge unit
2 Replacement fuses, 1 Instruction manual, 1 Tool for removing the rotor
1.6Warranty
The centrifuge has been subjected to thorough testing and quality control.
In the unlikely event of any manufacturing faults occuring, the centrifuge and rotors are covered by warranty for a period of one year from date of delivery.
This warranty becomes invalid in case of wrong operation, use of non-appropriate spare parts or accessories and non-authorized modification of rotor or centrifuge.
The manufacturer reserves the right for any technical modifications of the product in respect to technical improvement.
2.Installation
2.1Unpacking the centrifuge
The centrifuge is supplied in a carton on a pallet. Remove the tightening straps . Open the carton, take off the packing and remove the carton.
The instruction manual and the accessories mentioned under 1.5 should be kept with the centrifuge.
2.2Transport
Avoid impacts during transportation and do not drop the unit to perserve it from being damaged.
2.3Required space
The centrifuge should be installed on a rigid, even surface. The Z 400 K should only be operated on a stable laboratory table/cabinet etc..
Balance the centrifuge with a spirit level.
To guarantee the necessary heat dissipation, the unit has to be placed in that way, that there is a space of minimum 15 cm on each side of the unit.
Never place the centrifuge in positions subject to excessive heat, e.g., strong sunlight, as the performance of the unit is based upon an ambient temperature of +23°C.
Attention:
The new safety rules require a safety operation cycle of 30 cm around the centrifuge. Mark this area to indicate that no person and no dangerous
!material (e.g. comprising inflammable or infectious liquids) are present during centrifugation.

2.4Installation
-Check that the power supply corresponds to that on the manufacturer's rating label which is mounted on the rear panel, then connect the power cord to the centrifuge and the socket.
-The line voltage circuit breaher is maximum a 16 Amp. type K slow release for commonly used instruments.
-That an ermergency switch is installed outside the room to disconnect the power supply in case of a troubled run
-The power switch is at the rear side of the unit. Plug in the power cord.
-The digital indications on the display are lighting up.
-Press key "lid". You can open the centrifuge lid now (see chapter 4.2).
3.How to install and load a rotor
3.1Mounting and securing a swing out rotor
Clean the motor shaft, as well as the rotor mounting hole with a piece of cloth and place the rotor on the motor shaft ensuring that the pins align correctly with the rotor slots (see sketch 1).
Incorrect |
Correct |
sketch 1 |
Hold the rotor with one hand and secure the rotor to the shaft by turning the rotor nut counter-clockwise.
When loading the buckets and tube racks you should proceed according to sketch 2. It is very important to load the rotor with the complete set of buckets/tube racks. The bucket insert bolts of the rotor should be regularly greased with silicone grease.
Fill the tubes equally by eye-measuring and insert them into the tube-holes or tube racks. The difference in weight between the buckets should not exceed 10 grams.
