manual carefully.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: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

1.2 Description

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.

1.3 Safety 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.

1.6 Warranty
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.

2.1 Unpacking 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.

2.2 Transport
Avoid impacts during transportation and do not drop the unit to perserve it from

being damaged.

2.3 Required 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.
