2. Before operating the unit
Installation procedures/precautions
・
Put specimens with appropriate spaces between them. Too many specimens may prevent
proper temperature control. To assure proper temperature control, put specimens with a
space at least 30% of the shelf board area.
Assure at least 30% of space
(5)
Do not put an specimen on the bottom of the internal bath.
・
Operating the unit with a specimen directly put on the bottom of the internal bath might
degrade its temperature characteristics. This also may cause corrosion, damage or rust of
the internal bath. Never put any specimen on the bottom surface.
・
When putting specimens, take care not to allow them touching the wall on which the heater,
the sensor or other devices are installed. Put specimens on the shelf board included with
the unit.
(6)
Take special care for specimens including:
①
Specimen that contains a flammable or explosive component.
・
This unit is not explosion-proof. Never attempt to dry or process a specimen that contains
a flammable or explosive component.
②
Corrosive specimen
・
Take care for handling a corrosive specimen. Although SUS304 stainless steel is used for
major components of this unit, they might corrode if they are subject to strong acid. Also
note that packing may corrode with acid, alkaline substances, oil, or organic solvent.
③
Specimen that contains much moisture
・
While operating the unit at a lower temperature, cooling capacity of the evaporator may be
degraded and the set temperature may not be maintained due to too much frost on the
evaporator. When frost is confirmed through the frost observation window at the bottom
of the bath in the unit, perform defrosting.
④
Operation with devices of higher heat load introduced
・
By leading a power cable from the cable port, you can operated devices in the unit. Note,
however, that operation of devices with higher heat load will increase temperature in the
unit.
