Caution
During a thunder storm
During a thunderstorm, turn off
the power key immediately, then turn off the circuit breaker and
the main power. If this procedure is not followed, fire or electrical shock may be caused.
If the electric failure shall be occurred,
When power is shut off due to turning the ELB “OFF” or a power failure during GB210A/ADL311S
operation (while the blower is in operation or liquid is being sent), the mode will return to
①
or
②
after recovery.
①
The mode will return to the initial state when the inlet temperature is 60
℃
or less or the
outlet temperature is 50
℃
or less.
②
When the temperature inside the path is high, the unit will continue operation until the inlet
temperature drops to 60
℃
or less or the outlet temperature drops to 50
℃
or less while
only the blower returns.
Do not perform unattended operation during activating the unit
Do not perform unattended operation during activating the unit. Since the unit is in idling status
and the nozzle is blocked of after the operation using sample, the temperature around outlet is
increased and the remaining sample is flown from the sample tube disconnected from the unit,
and this failure may cause the indeterminism accident.
Any people other than the qualified personnel shall never attempt to
operate the unit.
Take sufficient care for the control of the unit so that any people other than the qualified
personnel shall never have a chance to operate the unit.
Always monitor and check the oxygen concentration.
Always monitor the oxygen concentration in the unit to assure safety.
Take care when opening the unit.
Be sure to confirm that the oxygen concentration has returned to 21% and avoid putting your
face close to the exhaust port carelessly when opening the unit.
Take care for solvents you are going to use.
The unit has been designed to use isopropyl alcohol and ethanol.
Service lives of a filter element or packing may change depending on the type of solvent used.
When leakage of gas or other troubles occurs inside the unit, immediately replace the defective
part with a new one. Check whether a solvent can be used or not in the “About the applicable
solvents” in the section 5. Handling precautions.
Take care for the use of water based solvents.
When you are going to use a water based solvent, remove the GB210A and use ADL311S or
GA310 alone.
See “Restrictions by the melting point” in the section 5. Handling precautions (P.24).
