1.2 Safety Precautions
Before using he ins rumen , please read his opera ion manual o ensure correc
usage hrough unders anding. Incorrec handling of he ins rumen could possibly
resul in personal injury or physical damage on he ins rumen or i s accessories.
• ALWAYS loca e he ins rumen on a fla , rigid and s able able capable of
wi hs anding he weigh of he ins rumen and i s spinning opera ion.
• ALWAYS make a safe y zone of 30 cm around he cen rifuge o indica e ha
nei her hazardous ma erials nor persons should be permi ed wi hin he area
during opera ion.
• ALWAYS posi ion he ins rumen wi h enough space on each side of
ins rumen o ensure proper air circula ion.
• ALWAYS ins all he ins rumen wi hin a empera ure and humidi y con rolled
environmen . (Permissible ambien empera ure: +5 °C ~ +35 °C, Rela ive
humidi y: ≤ 85 %)
• Before connec ing he power, check he ra ed vol age.

3
• Unapproved ro ors and associa ed accessories should no be used.
• Before opera ing he ins rumen , check if he ro or and he ro or lid are
securely fas ened.
• The ins rumen should be opera ed wi h a ro or properly ins alled and secured
o he mo or shaf .
• Moun he ro or on he mo or shaf properly, check i wi h spinning manually.
• Do no s op he ro or by ouching wi h hand during he ins rumen is running.
• Emergency door open should be performed only when spinning is comple ely
s opped.
• The ra ed speed or specific gravi y should no be exceeded. Samples whose
densi y is grea er han 1.2 g/ml mus have reduced maximum ro a ional speed
o avoid ro or failure.
• The sample con en should no exceed 80 % of o al capaci y of a ube.
O herwise, i would cause spillage of sample fluid and even he ube breakage.
• ALWAYS load he ubes symme rically wi h evenly weigh ed samples o avoid
ro or imbalance. If necessary, use he wa er blank o coun erbalance he
unpaired sample.
• The opera ion speed should no exceed he highes value of he individual
guaran eed g-forces of each cen rifuge, ro or, bucke or adap ors and sample
con ainer, especially he guaran eed g-force of sample con ainer should no be
neglec ed.
• The ro ors should be cleaned and kep dry af er every use for longer life and
safe y.
• ALWAYS disconnec he power supply prior o main enance care and service
o avoid elec rical shock.
• ALWAYS use proven disinfec ion procedures af er cen rifuging biohazardous
ma erials.
• Flammable, oxic, radioac ive, explosive, or corrosive ma erials should no be
cen rifuged.
• When i is necessary o use oxic or radioac ive ma erials or pa hogenic micro-
organisms which belong o he Risk Group II of WHO: “Labora ory Bio- safe y
Manual,” should follow na ional regula ions.
Attention
• o not place dangerous materials within 30 cm distance around the
instrument, and that is also recommended by IEC 61010-2-020.
• Use the emergency door open function only when the door button on the
control panel is dumb under the condition of complete stop of rotor
running.
• Never try to open or move the instrument if it is not completely stopped.
• If the power input is more than +/- 10% of the recommended voltage or
fluctuates frequently, it may cause malfunction of the instrument and
often result in serious damage.
• Install the instrument at a place without any kinds of corrosive gases.

lid comple ely, i will be crushed.
10. Posi ioning of sample ubes:
• Before loading sample ubes, check for wa er drops or dir in he ro or hole
or inner adap or.
• If here is a wa er drop or dir in he ro or hole or inner adap or, remove i
wi h sof dry clo h.
• Tubes should be placed in he ro or wi h same amoun of samples a
symme rical posi ions.
• Only use appropria e cen rifugal ubes and do no exceed he speed beyond
he ube’s max g-force.
• For safe y, fill he sample for 70 ~ 80 % in he ubes.
• If he number of samples is no in pair, please load he con rol ubes a each
symme rical posi ion. O herwise, i resul s noise and vibra ion, and
even ually damages he ins rumen .
