Warning
 The area near the inlet is hot.
Put on protectors such as heat-resistant gloves, and take care not
to get burned.
Never disable the solenoid lock manually during a measurement
because it is very dangerous.
 When handling a sample boat or a mercury collector tube for a
measurement or the like, take care not to get burned.
When handling, put on protectors such as heat-resistant gloves,
and use boat tongs.
 After washing the sample boat, first dry it at about 100

C. Then,
heat at a high temperature to lower the blank. Heating a wet boat
to high temperatures can damage the sample boat.
 Hot exhaust (general exhaust) is discharged from the rear upper
part of the instrument.
Take care not to get burned.
 When touching the instrument for maintenance, make sure that it
has been cooled sufficiently.
When touching, put on protectors such as heat-resistant gloves.
Otherwise, you may get burned.
 When the instrument is turned off, the surface temperature can be
high due to the heat from the heater.
Be cautious about burn injuries and do not place anything on the
instrument.
 Take care that there is no dust on the filter of the fan in the rear.
If the filter is clogged, it will cause the abnormal temperature rise
of the instrument, which is very dangerous.
 Before using a reagent, procure and administer the safety data
sheet (SDS).
 Disconnect the power cable from the instrument before
maintenance work.
Otherwise, an electric shock or a failure caused by a short circuit
may result.
 Do not measure directly sample decomposed using nitric acid.
Otherwise, the activated carbon filter on the exhaust side may
generate heat.
Dilute nitric acid to 5 wt% or less.
