moved.
Use only the power cord specified for this product, with the
grounding conductor of the power cord connected to earth
ground.
Use only the fuse type and rating specified by the manufac-
turer for this instrument. The use of fuses with improper rat-
ings may pose electrical and fire hazards.
To avoid fire or shock hazard, observe all ratings and markings
on the instrument.
Do not power the instrument in environments that are poten-
tially explosive or at risk of fire.
Prior to cleaning and/or performing maintenance on the in-
strument, switch off the instrument and remove the power
cord.
Only cleaning materials described in this manual may be
used, as other materials may damage parts.
It is recommended to always wear protective apparel and eye
protection while using this instrument.
All warning symbols that appear in this manual must be care-
fully observed.
1.5 Disposal Management Concept
The applicable local regulations governing disposal must be
observed. It is the user’s responsibility to arrange for the prop-
er disposal of the individual components.
All parts which may contain potentially infectious materials
must be disinfected by suitable, validated procedures (auto-

HumaMax Micro | User manual
12
claving, chemical treatment) prior to disposal. Applicable local
regulations for disposal must be carefully observed.
The instruments and electronic accessories (without batter-
ies, power packs etc.) must be disposed of according to the
regulations for the disposal of electronic components.
Batteries, power packs and similar power sources must be
removed from electric/electronic parts and disposed of in ac-
cordance with applicable local regulations.
1.6 Instrument Disinfection
Instruments or parts which may come in contact with biologi-
cal samples (patient specimens, controls etc.) should be con-
sidered at least potentially infectious.
Before performing any service work on the instrument, it
is very important to thoroughly disinfect all possibly con-
taminated parts. Before the instrument is removed from the
laboratory for disposal or servicing, it must be decontami-
nated/disinfected. Decontamination/disinfection must be
performed by authorised, well trained personnel and in ob-
servance of all necessary safety precautions. Instruments to
be returned must be accompanied by a disinfection certificate
completed by the responsible laboratory manager. If a disin-
fection certificate is not supplied, the returning laboratory
will be responsible for charges resulting from non-acceptance
of the instrument by the servicing centre or from intervention
by governmental authorities.

1.7 Notice
Every effort has been made to avoid errors in text and dia-
grams. HUMAN, however, assumes no responsibility for any
errors which may appear in this publication. It is the policy of
HUMAN to improve products as new techniques and compo-
nents become available. HUMAN therefore reserves the right
to change specifications if necessary in the course of such im-
provements.
1.8 Biohazard Warning
Analytical instruments for use in the clinical laboratory en-
vironment may come into contact with human samples and
controls which should be considered at least potentially in-
fectious. Therefore every part and accessory of the respective
instrument which may have come into contact with such
samples must equally be considered as potentially infectious.
For safety reasons, we recommend to label such instruments
with the “BIOHAZARD” warning label below.

1.9 Servicing Note
Before doing any servicing on the instrument it is very impor-
tant to thoroughly clean all possibly contaminated parts. If
the instrument has come into contact with potentially infec-
tious materials, it must be decontaminated before the instru-
ment is removed from the laboratory for disposal or servicing,.
Decontamination should be performed by authorised well-
trained personnel only, observing all necessary safety precau-
tions. Instruments to be returned have to be accompanied
by a decontamination certificate completed by the respon-
sible laboratory manager. If a decontamination certificate is
not supplied, the returning laboratory will be responsible for
charges resulting from non-acceptance of the instrument by
the servicing centre, or from authority’s interventions.

The HuMax Micro bench-top centrifuge is especially designed
for the separation of blood samples, urine particles sedimen-
tation and for carrying out the other routine applications in
microbiology laboratories.
The HuMax Micro is ideal for hospital and research laborato-
ries.
The HuMax Micro ensures safe and easy operation by means
of a system, which does not allow the centrifuge to operate if
the lid is not closed.

3.4 Positioning
Place the centrifuge on a bench-top able to support its weight
and vibrations, in clean, non-corrosive environment. Leave a
30 cm space each side of the centrifuge.
3.5 Inspection
Before installation, the rotor should be inspected for damage
and cleanliness. Dirt and particles inside the inserts can cause
the breakage of tubes and lead to a major imbalance. The cen-
tral hole of the rotor and the motor shaft must also be kept
clean and dry at all times.
3.6 Loading
Each tube insert must be the same weight as the one dia-
metrically opposite for balancing. If the number of tubes to
be centrifuged is less than the capacity of the rotor, the tubes
must be placed in opposite inserts. If an odd number of tubes
is be centrifuged, a water-filled tube of the same weight must
be used for balance.
When the centrifu-
ge is running, no
persons, dangerous sub-
stances or objects may
be within the safety mar-
gin of 30cm around the
centrifuge
Rotor imbalance may cause major da-
mage to the rotor and
centrifuge. Never at-
tempt to introduce li-
quids into the tube in-
serts.

- You should feel a ‘click’ when the rotor is properly loaded
on the shaft. If not, there may be something stuck between
the rotor and the shaft. Double check and clean it if neces-
sary.
- Rotate the rotor slightly with your fingers to check if the
rotor vibrates, if so attach the rotor again.
- Close the door and then start running.
- The method of removing the rotor is as same as the above
mentioned.
3.8 Routine Lid Opening
1. Switch off the power switch on the back
