SYMBOLS ON UNIT
The symbols are attached to the biomedical freezer. The following table describes the symbols.
This symbol is attached to covers that access high-voltage electrical components to
prevent electric shock. Only a qualified engineer or service personnel should be
allowed to open these covers.
This symbol indicates that caution is required. Refer to product documentation for
details.
This symbol indicates an earth.
This symbol means “ON” for a power switch.
This symbol means “OFF” for a power switch.
ENVIRONMENTAL CONDITIONS
This equipment is designed to be safe at least under the following conditions (based on the IEC
61010-1):
■ Indoor use;
■ Altitude up to 2000 m;
■ Ambient temperature 5 o C to 40 o C;
■ Maximum relative humidity 80 % for temperature up to 31 o C decreasing linearly to 50 % relative
humidity at 40
o
C;
■ Mains supply voltage fluctuations up to ±10 % of the nominal voltage;
■ Transient overvoltages up to the levels of OVERVOLTAGE CATEGORY II;
■ Temporary OVERVOLTAGES occurring on the mains supply;
■ Applicable pollution degree of the intended environment (POLUTION DEGREE 2 in most cases)
INTENDED USE AND PRECAUTIONS
This equipment is designed for low temperature storage of DNAs and plasma.
■ The effective storage period depends on the sample condition and storage temperature. It is
necessary to determine the storage temperature and period suitable for the purpose.
■ For the plasma, the lower storage temperature should be required for longer term storage. It is
recommended to store the plasma at -80 o C or lower.
