1.1 Safety Devices and Notices
To ensure operator safety the centrifuge has
the following electrical and mechanical
characteristics:
• The centrifuge will not start unless the lid is
locked.
• The lid cannot be opened during
centrifugation.
• The centrifuge has electronic self-diagnosis
capability; any possible electrical system
malfunctions are displayed digitally. At the
same time, the centrifuge is disabled to
prevent unsafe operation of the machine.
• The centrifuge is equipped with an
automatic load imbalance safety device.
• The case of the centrifuge is armored, and
the reinforced bowl is made of AISI 304
stainless steel.
2.1 Transport, Packaging, Lifting
The centrifuge is shipped in
special packaging to protect it
from possible harm.
Due to the weight of the machine,
proper handling equipment (e.g.:
pallet jack or fork lift) must be used. The
handling equipment should comply with
current regulations, and should only be used
by properly trained individuals.
1. The centrifuge should be stored and
transported under the following conditions:
a) Ambient temperature -20°C to +50°C.
b) Relative humidity up to 90% and not
exceeding the dew point.
2. After the centrifuge is unpacked, the
contents of the package should be carefully
compared to the items on the packing list.
3. Retain the packaging until the centrifuge
has been tested.
2.2 Installation
The machine should be installed in a room
free of dust and moisture. Place the centrifuge
on a bench top rigid and strong enough to
comfortably support its weight.
• The lid is supported by a strong, dependable
gas spring that holds the lid open until the
operator actively closes it.
• The electrical main has a bipolar switch.
• Ground connection resistance, applied
voltage and leakage current are tested and
certified.
• The centrifuge is equipped with identification
plates and operating instructions.
IMPORTANT:
AT LEAST 2 PEOPLE ARE REQUIRED TO
LIFT THE CENTRIFUGE FROM THE P ALLET
AND PLACE IT ON THE BENCH.
WARNING:
LEAVE 12 INCHES OF FREE SPACE ON
EACH SIDE OF AND BEHIND THE
MACHINE TO FACILITATE PROPER
VENTILATION.

2.3 Power Source Wiring
Check main lines and frequency:
They must correspond to the
values shown on the instrument
identification label.
2. Check the lid indicator on the display panel.
The light should be on indicating that the rotor
is stationary and that the lid can be opened.
3. Pull the lever on the top right side of the
machine to open the lid.
PK130R 230V:
230 V + 5% - 10% 50 Hz (1 phase + ground)
PK130R 120V:
120 V + 5% - 10% 60 Hz (1 phase + ground)
WARNING:
ENSURE THAT THE POWER SOURCE IS
PROPERLY GROUNDED.
The centrifuge is equipped with R.F.I.. filters.
The manufacturer declines all responsibility
for any damages due to improper grounding
of the machine.
2.4 Environmental conditions
- Indoor use.
- Temperature: 5°C to + 40°C.
- Maximum relative humidity: 80% for
temperatures up to 31°C decreasing linearly
to 50% relative humidity at 40°C.
2.5 Lid Unlock
1. Turn the centrifuge on (switch is on
the left side of the unit).
WARNING:
BEFORE PROCEEDING TO THE
INSTALLATION OPERATION, IT IS
IMPORTANT TO TURN THE CENTRIFUGE
OFF.
4. After opening the lid, remove any possible
packaging around the spindle. Unscrew the
rotor nut from the top of the spindle. Carefully
clean the inside of the centrifugation chamber
removing any packaging residue. Because of
the turbulence caused by centrifugation, solid
particles accidentally left in the chamber could
create excessive wear of the bowl and rotor.
2.6 Emergency Lid Unlock
In the event of power failure, the lid can be
opened using the special tools supplied with
the centrifuge. The centrifuge must be
unplugged before starting this procedure.
1. Remove the nylon screw in the hole on the
right side of the centrifuge as identified below.
2. Insert the unlocking tool, keeping the blade
horizontal (
3. Lift the unlocking tool while simultaneously
pulling the lever (

4. After the lid is open, replace the nylon screw .
2.8 Fitting the Rotor to the Drive Shaft
WARNING:
SHOULD THE POWER FAIL DURING
CENTRIFUGATION, WAIT AT LEAST 40
MINUTES FOR THE ROTOR TO STOP
TURNING. OPEN THE LID CAUTIOUSLY
AND OBSERVE THE ROTOR; IF IT IS STILL
ROTATING, CLOSE THE LID AND WAIT 10
MINUTES MORE BEFORE REPEA TING THE
OPERA TION.
2.7 Inspection
Before installation, the rotating equipment
should be thoroughly inspected for corrosion
and dirt (see 6.3). The rotor and spindle should
be clean and undamaged. These accessories
should be wiped clean before each use. Any
failure to follow the above advice may have
serious consequences for the safety of the
appliance. Corrosion can lead to stress
fatigue, which will eventually weaken the rotor
and may lead to disruption and severe
damage to the centrifuge. If visible signs of
corrosion or anomalies in the rotor or buckets
are present, do not use the affected
accessories. Contact an authorized service
provider for assistance.
- Remove the rotor fixing shaft nut.
- Check the cleanliness of the shaft and
the rotor.
- Place the rotor on the shaft.
- Secure the rotor on the shaft by turning
the fixing nut clockwise.
- Tug on the rotor to make sure that it is
secure.
WARNING:
BE SURE THAT THE ROTOR IS LOCKED
BEFORE STARTING THE CENTRIFUGE.
2.9 Removal of the Rotor
To remove the rotor from the motor shaft :
Using the wrench supplied, unlock the shaft
nut. Remove the nut and lift the rotor with both
hands.
