SAFETY NOTICES
○
Safety During Installation and/or Maintenance
●
To avoid electrical shock hazards, follow below when servicing the centrifuge.
1) Be sure to turn off the POWER switch and turn off the distribution board of your
centrifuge room if your centrifuge is equipped with a three wire power cord.
Then wait at least three minutes and then remove covers or tables from the
centrifuge.
2) Be sure to turn off the POWER switch and unplug the power cord from the
receptacle if your centrifuge is equipped with a power cord with a plug. Then
wait at least three minutes and then remove covers or tables from the centrifuge.
●
Elevate the centrifuge completely by using the four level adjusters and level it.
If the centrifuge is elevated incompletely, it can cause significant movement of the
centrifuge in the event of the rotor disengagement.
●
Do not remove the adapter of the inner of the door, the cover of the left side of
the centrifuge and the caps of the inside of rotor chamber except using
a continuous flow rotor in the CR22N refrigerated centrifuge. The CR22N
refrigerated centrifuge does not conform to the CE marking requirements when
using a continuous flow rotor due to the construction of the rotor.
Do not remove the adapter of the inner of the door, the cover of the left side of
the centrifuge and the caps of the inside of rotor chamber if your centrifuge is
the CR21N refrigerated centrifuge. A continuous flow rotor is not applicable to
the CR21N refrigerated centrifuge.
●
Installation or relocation of your centrifuge must be done by the authorized Hitachi
Koki service representative. Contact a Hitachi Koki authorized sales/service
representative.
●
Repairs, disassembly, and other modifications to the centrifuge are strictly
prohibited unless performed by a Hitachi Koki authorized sales/service
representative.
●
Avoid a place exposed to ultraviolet rays for operation or storage of the centrifuge.
Otherwise, the covers can be discolored and the coating can be peeled off easily. If
installation in such place is unavoidable, cover the centrifuge with a cloth after
operation to protect from ultraviolet rays.
○
Electrical Safety
●
Your centrifuge must be grounded properly to avoid electrical shock hazards.
●
Do not place containers holding liquid in the rotor chamber or on or near the
instrument. If they spill, liquid may get into the instrument and damage electrical
components.
○
Safety against Risk of Fire
●
This centrifuge is not explosion proof centrifuge. Never use explosive or flammable
samples, or materials that chemically react vigorously. Do not centrifuge such
materials in this instrument nor handle or store them near the instrument.
