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.

a)
Unplug the power cord. Turn the on/off switch to “off”
