2. Before operating the Equipment
Precautions when installing the Equipment
2.For Ventilation
When the product is used (with the damper opened) for ventilation, take such measures as to
ensure sufficient ventilation around the installation location. When ventilation around the product
is not sufficient, hot air discharged through the exhaust port may cause increase in temperature
of the location or fume and gas generated from the sample may fill the space. Be sure to connect
the exhaust duct to the exhaust port to ensure discharge of hot air to the outside. The exhaust
duct is optionally available and should be ordered separately. Se
e “P. 70 List of Accessories.”
3. Install the Equipment on leveled location.
Install this Equipment on leveled floor. If it is installed on rough and/or slope floor, vibration or
noise will be occurred, and unexpected trouble and malfunction may be happened.
Weight of this Equipment is as follows:
DNF301 approx. 50kg/DNF401/411 approx. 75 kg /DNF601/611 approx. 90kg
Use cargo handling equipment for carrying and installation. Two or more people shall be
necessary when transporting by humans.
4. Implement safety measures when installing the unit.
May be injured by moved and/or fallen this Equipment down by earthquake and/or unexpected
impact. Recommend to install this Equipment at the place away from the access door and to
take other safety steps.
5.
Implement appropriate safety measures after installation.
May be injured by moved and/or fallen this Equipment down by earthquake and/or unexpected
impact.
To ensure the safety, be sure to provide any adequate measur to the main body and to the
installation surface to prevent overturn.
6. Ventilate sufficiently for the Equipment
Do not operate the Equipment blocked in the radiating slit holes-Louver on its side and back
panels and top panel. Refer to 3. “Name and Functions of each part” on page 11 for the location
of Louvers.
Internal temperature will rise, causing a malfunction of the controller to compromise the
performance as well as to cause a possible accident or a fire.
7. Do not operate at the location of liquid splashing.
Do not operate this Equipment at the location of liquid splashing. If Controller of this Equipment
will be wetted by splashing any kind of liquid, it may cause accident, controller malfunction,
electrical shock and/or fire.
8. Never operate in an atmosphere where flammable or explosive gas is present.
Never operate this Equipment in an atmosphere where flammable or explosive gas is present.
This Equipment is not explosion-proof. Spark may be discharged by switching Earth Leakage
Breaker (ELB) “ON(
|
)” and “OFF(○)” and also relay during operation, and then it may cause
fire or explosion.
See Chapter 13. “List of Dangerous Substances” for flammable and explosive gases on
