2. Before operating the unit
Installation procedures・precautions
(4) Do not put an instrument on the bottom of the internal bath.
・ Operating the unit with a fixing 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 fixing on the bottom surface.
・ When putting instruments, take care not to allow them touching the heater, the sensor or
other devices that are installed on the bottom. Put instruments on the shelf board included
with the unit.
(5) Take special care for instruments shown below:
①
Instruments that contain flammable or explosive components or such instruments to which
samples containing those components are attached.
・ The unit is not explosion proof. Never attempt to dry or process instruments to which
samples that contain flammable or explosive components are attached.
② Corrosive instruments
・ Take care for handling of corrosive instruments or instruments to which corrosive
components are attached. Although SUS304 stainless steel is used for major
components, note that they might corrode with strong acid. Note that packings may
corrode with acid, alkali, oil or organic solvents.
Always operate the unit with the exhaust ports open.
・ There are two exhaust ports on the top surface of the unit. In regular operation, open both
of two vent holes. Adjust their opening level according to the water amount attached to a
specific instrument.
(6)
Note that high temperature steam may be blowing out of the
exhaust ports.
To prevent a burn, never try to look into the exhaust ports or
touch those parts with bare hands.
(7) Always shut the door completely.
・
Make sure that the clamp on the right side of the door is completely locked before
operating the unit.
(8) About two-tier stacking
・
Do not stack two DG400 units on each other in two tiers.
