3.2.2 Location (Required ventilation rate)
Installation of multiple products
Keep sufficient space between products so that the air vented from one product will not be taken
in by other products.
 Installation Area Ventilation
① Facility having a large installation area (that can vent the air naturally)
Make an air vent on a wall at a high level and another air vent on a wall at a low level, to
allow for adequate airflow.
② Facility having a small installation area (that can not vent the air naturally)
Make a forced air exhaust vent on a wall at a high level and an air vent on a wall at a low
level.
