Safety:
Your PowerSpin C8624 centrifuge is a carefully designed and built instrument. When
operated properly, it presents no safety hazards, however, please take note of these safety
precautions.
Lid with zero rpm lid latch (electronically operated):
NEVER ATTEMPT TO OPEN THE LID UNTIL THE ROTOR HAS COME TO
COMPLETE STOP!
Load Balance:
Always make sure that the load is balanced before operating the instrument.
It is very important that tubes with equal loads are placed opposite each other in the rotor.
Also, when spinning a single specimen tube, another specimen tube of the same size filled
with water must be installed directly across from the specimen tube to maintain balance. If
the centrifuge is not properly balanced, damage could occur. If excessive noise or
vibration is noticed during a run, stop the centrifuge and recheck the balance.
Maintenance:
Be sure to disconnect the power before attempting to clean.
This centrifuge is designed to be relatively maintenance free. The motor is a brushless
type and has permanently sealed bearings so oiling is not necessary. A surface cleaner
such as Formula 409 can be used to clean the outside of the instrument. The rotor chamber
and cover can be disinfected with a mild solution of bleach or other disinfecting liquid and
allowed to dry. Do not drench or immerse the unit in any liquid!
Calibration:
It is recommended that your centrifuge’s RPM be calibrated at least every 6 months. This
period is suggested by both the FDA and C.L.I.A. guidelines. The speed should fall within
±100rpm of the speed display. Since the speed displayed on Unico C8624 is from a real
time digital sensor mounted on the motor shaft, it reflects the real running speed of the
rotor. The timer is an electronic timer and no calibration is required.
Electrical Shock Hazard:
Do not attempt to operate this instrument near water or liquid spill. Unplug the unit before
cleaning or repairing. Periodically check the condition of the power cord for cuts or
damage. Do not operate with a damaged cord.
Biohazard:
If a tube breaks, a biological hazard may exist. Unplug the instrument. Clean using
approved laboratory procedures. Always wear the proper protective clothing and gloves.
Use a suitable disinfectant and dispose of the sample properly. Refer to the guidelines set
forth by OSHA, CLIA, etc.

7
Service:
If you feel that your centrifuge needs factory service, please call us and speak to a
customer service representative to determine the nature of the problem. Simple problems
may be resolvable over the telephone. If the instrument needs to be returned to Unico, a
R.G.A. (return goods authorization) number will be issued. Please reference the R.G.A.
number on the paperwork packed with the instrument, and on the outside of the carton.
REPAIRS OR MODIFICATIONS MADE TO THE CENTRIFUGE BY AN
UNAUTORIZED PARTY WILL VOID THE WARRANTY.
Problem Solving:
1. Centrifuge does not start:
a) Check to determine if centrifuge is plugged in.
b) Check that lid is properly closed.
d) Check that Power switch in the back of unit is in the “on” position.
e) Check that the power indicator light (with the switch) is lit. A failure of the
power light to illuminate could indicate a need for a new fuse when the unit is
properly plugged in, switch is turned on and the lid is closed.
2. Excessive noise when running. If the noise is irregular or different in tone, be
sure that there is no paper or debris in the rotor or rotor chamber. Make sure
the load is balanced in the rotor.
3. Indicator light fails to light:
a) Unit is not turned on or no power supply.
b) Fuse is blown.
4. Fuse Replacement:
Caution: DISCONNECT THE POWER CORD BEFORE REPLACING FUSE.
Follow the procedures below to replace the fuse:
a) Unplug the power cord. Turn the on/off switch to “off”
b) Remove the power cord from the power inlet on the back of the centrifuge.
c) Locate the fuse holder. The fuse holder is a part of the power inlet.
