application by offering a wide range of accessories. It accomodates swing out
rotors up to a max. capacity of 4 x 100 ml, as well as angle rotors up to 10.000 rpm
(microtiter rotor and hematocrit rotor see brochure).

1.2 Safety precautions to be observed before operating the centrifuge

Do not operate if:

- the centrifuge has not been installed correctly

- the centrifuge is partly dismantled

- service has been attempted by non-authorized or non-qualified

- the rotor has not been installed securely on the motor shaft

Do not operate the centrifuge with rotors and accessories not belonging to the
standard range of accessories of this centrifuge without obtaining the prior

personnel

permission of the manufacturer. Exception: tubes and bottles made of glass or
plastic normally available in the laboratory.

Do not operate the centrifuge in explosive atmospheres.

1.3 Safety standards
The centrifuge corresponds to the general requirements set by German law for
medical apparatus, "Med GV" group 3.

The following standards have been considered for the production of our
centrifuges:

- Accident prevention rules for centrifuges UW-VBG 7z

- Accident prevention rules for electrical equipment & installations

UW-VBG4

- DIN 58970, part 1,2 and 4 for centrifuges and centrifuge tubes

- Electrical interference suppression according to interference degree

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 1 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.

Installation

2.1 Unpacking the centrifuge

The centrifuge
Z 320 is sup-

plied in a
carton protec­ted by PU
foam.

Open

the carton and

take off the

upper foam
part (including

the accesso-

ries) and
remove the
centrifuge.

The instruction

manual and the

accessories mentioned under 1.5 should be kept with the centrifuge.

2.2 Required space

The centrifuge should be installed on a
be operated on a stable laboratory table/cabinet etc..

To guarantee sufficient ventilation, please ensure that the centrifuge has at least

rigid,

even surface. The Z 320 should only

It is recommended that the centrifuge is not sited in positions subject to excessive
heat, e.g. strong sunlight, radiators etc. as heat-build-up can occur within the
centrifuge bowl.

2.3 Installation

1.

Before operating the centrifuge check that the power supply corresponds to that

on the manufacturer's rating label which is mounted on the rear panel.

2.

Switch on the power switch (1), the green control lamp of the power supply (1),
as well as the white control lamp of the lid release (2) will light. The lid can then be
opened by pressing firstly the lid release switch (2), as well as secondly the mecha­nical lid lock (3), (see figure 3).

Figure 3

3. Remove the locking nut (1) on the motor shaft by turning clockwise and the
transport protection out of the centrifuge bowl (2), (see figure 4).

Figure 4

3. How to install and load a rotor

3.1 Mounting and securing a swing out rotor

Clean the motor shaft (3), as well as the rotor mounting hole (2) with a piece of cloth
and place the rotor on the motor shaft ensuring that the pins (4) align correctly with

the rotor slots (1). Secure the rotor to the shaft by turning the rotor nut counter-

clockwise (see figure 5+6).

it is very important to load the rotor with the complete set of buckets / tube racks.
Fill the tubes equally by eye-measuring and insert them into the tube-holes,
respectively tube racks. The difference in weight between the loaded buckets / tube
racks should not exceed 10 grams.
