5. Cautions on handling
Caution
5. Do not operate the unit with the door open.
・
When the unit is operated with the door open, the heater may overheat pausing a possible
danger. Be sure to operate the unit with the door closed.
・
After operation has been completed, do not leave the unit with its door open in order to, for
example, cool down samples earlier. Heat from inside the bath may cause deformation of
the control panel of a malfunction of the control devices.
6. Prohibition of use of corrosive samples
Although stainless steel is used for components in the bath, note that they might corrode
with strong acid. Door packing is made of silicon rubber. Note that silicon rubber packing
may corrode with acid, alkali, oil or halogen-based solvent.
7. Always operate the unit at a correct ambient temperature.
Operational temperature range for the model DX302C/402C/312C/412C is room
tempe5
℃~
300
℃
; DX602C/612C room tempe5
℃~
280
℃
.
Never try to operate the unit outside the operating temperature range.
8. About placement of samples
Withstand load of the shelf boards included is approx. 15kg. Do not place a sample heavier
than this withstand load.
When putting samples, arrange them as dispersed as possible.
Too many samples may prevent proper temperature control. To assure proper temperature
precision, put samples with a space at least 30% of the shelf board area.
9. Do not put a sample on the bottom inside the product.
Never place a sample on the bottom, since if the unit is operated with a sample directly
placed on the bottom of the internal bath, the optimal performance of the unit will not be
attained, and temperature in the product may increase excessively causing a malfunction.
Arrange samples on the shelf boards supplied and set the board on the shelf clamps.
10. About recovery from power outage.
When the power is applied again after the unit has stopped due to power outage, the unit
will automatically return to the status immediately before the power outage and resumes
operation.
Turn the ELB off if you do not want to resume operation by automatic recovery.
11. About two-tier stacking
Stack the units in two tiers using the special stacking clamps included as optional
accessories.
Do not stack the units directly on each other in two tiers.
