Emergency Lid-opening:
The lid features an electronically controlled safety system to prevent it from being
opened accidentally while the centrifuge is spinning. However, situations may
arise when the lid needs to be opened manually (For example if you lose electrical
power and samples are still in the centrifuge).
To open manually, locate the small hole on the upper right corner of the left side of
the centrifuge. Using a small screw driver (or a rod with 4.5mm or less in
diameter); insert the tool into the lid-opening hole; push the tool to release the
safety lock and open the lid.

Safety:
Your PowerSpin C8604 centrifuge is a carefully designed and built instrument. Please
take note of the following 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 (or an equal volume of another liquid) must be in-place directly opposite from
the specimen tube to maintain balance. If the centrifuge is not properly balanced, damage
could occur.
CAUTION: If excessive noise or vibration is noticed during a run, immediately press
“Stop” to turn off the centrifuge and recheck the balance.
Maintenance:
Be sure to disconnect the power cord before attempting to clean the centrifuge.
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!
CAUTION: Do not use any cleaning “SOLVENTS” on any part of the centrifuge as the
chemicals can cause damage to the instrument.
Periodic Rotor and Tube Holders inspection and replacement
Rotors and Tube Holders should be removed and inspected for defects at least every 6
months or each time the rotor is removed for cleaning.
Calibration:
According to Code of Federal Regulations Title 21, centrifuges require verification or
calibration as follows:
1) Before initial use; 2) after repair or adjustments; and 3) 6 month after use. The
centrifuge timer, however, should be checked for accuracy at least every 3 month. The
timer is an electronic timer is designed to be accurate to 5min ± 10sec. The speed should
fall within ±100rpm of the speed display. Since the speed displayed on the centrifuge is
from a real time digital sensor mounted in the motor, it reflects the real running speed of
the rotor.

7
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, etc.
Centrifuge Service:
If you feel that your centrifuge needs factory service, please contact the UNICO customer
service department for assistance. Simple problems may be resolved over the telephone. If
the instrument needs to be returned to UNICO, an 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:
