Safety Information
Alert Signals
During operation, maintenance and repair of this instrument,
the following basic safety notes should be observed. In case
of failure to follow these instructions, the warnings or notes
indicated herein, the basic protection provided by the
instrument, its safety criteria of design and manufacture, and
its predicted use range would be impaired. If the equipment is
used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
CAUTION: Important information is contained in
any item and should be carefully read. Failure to
observe the instruction would result in damage or
abnormal function of the instrument.
WARNING: The warning message requires
extremely careful operation of a certain step.
Failure to observe the instruction may result in
serious personal injury.
CAUTION: This instrument is for indoor use.
• The ground connection
To avoid the electric shock, the input power
line must be reliably grounded. The instrument
is equipped with the three-pin plug that has
the third pin (the pin connects the ground),
therefore, the plug should be used with the
grounded power socket only. This is a kind of
safety device. If the plug cannot be plugged
into the power socket, please ask the
electrician to install a correct power socket, so
as to make the grounded plug to work for
safety.
Thermo Fisher Scientific is not responsible for
any injury as a result of the user’s failure to
observe the following requirements.
• Observe voltage/power requirements
Before the instrument is connected to the AC
power source, the voltage of the power
source should be the same with the required
voltage of the instrument (a deviation of ±10%
is allowed). The rated load of the power
socket should not be lower than the
requirements of the instrument.
• The power cord
The instrument should use the power line cord
attached to it. If the power line is destroyed, it
must be replaced but not be repaired. The
replacement should be carried out with the power
line of the same type and same specification
(reach out to technical service team for further
information). No items should be put on the power
cord when the instrument is in operation.
• Connecting and disconnecting to/from
power source
The user should hold the plug to remove from
power source. When connecting the plug, user
should make sure it has been fully plugged in;
when removing the plug, do not pull the power line
forcefully. Do not position the equipment so that it
is difficult to operate the disconnecting device
(plug).
• Placement of the instrument
This instrument should be fixed in a low
RH (≤ 80%) and low dust place away from
water source (e.g. sink or water pipeline) and
the room should be well ventilated, and free of
corrosive gas or interference of strong
magnetic field. The instrument should not be
placed in a wet or dusty location.
The openings on this instrument are for
ventilation circulation and in order to avoid
over-heat of the instrument body they should
not be blocked or covered. When a single set
of instrument is used, the interval between
ventilation opening before and after the
instrument and its nearest object should not
be less than 25 cm. Also, don’t use the
instrument on loose or soft surface, or the air
inlet of instrument bottom might be blocked.

Digital Drybath Safety Information | 3
Excessive temperature will impair
performance or result in failure of the
instrument. This instrument should not be
used in locations subjected to direct sun light.
The instrument should be kept away from hot
gas, oven and all other heat sources. If the
instrument is to be stored for a long time, the
power plug should be withdrawn and the
instrument covered with soft cloth or plastic
film to avoid entrance of dust. The product is
powered by connecting the mains plug to a
standard socket-outlet. Always place the
product in such a way that it is easy for the
operator to disconnect the product from the
mains supply.
• Explanation of symbols
Attention, read user manual before use.
WARNING: There is a sign of
“CAUTION: HOT SURFACE!
ATTENTION: SURFACE HOT” on the
instrument. The metal part (module)
near the sign should not be touched
with any part of the body when the
instrument is operating in a high
temperature state or just finished
operation to avoid burns!
Alternating Current
Protective Conductor Terminal
CAUTION: In any of the following cases,
immediately turn off the power supply, withdraw
the power plug from the power socket, contact the
supplier for service:
• Liquid drops into the inside of the instrument.
• The instrument is rained on or water is spilled
on it.
• The instrument works abnormally, especially
if generating an abnormal sound or odor.
• The instrument is dropped or its casing is
damaged.
• The function of instrument obviously
changes.
