3.2.2 Location
„ 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 at indoor site
① In case of facility having a large installation area (that can vent the air naturally)
Make an air outlet on a wall at a high level and air inlet on a wall at a low level, to allow for
adequate airflow.
② In case of 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 inlet on a wall at a low level.
③
Using duct to exhaust the air
In case the indoor site cannot accept the exhausted air from the product or/and is air
conditioned, ventilate by installing a duct on the outlet ventilation of the product. Do not fasten
the duct on the outlet ventilation of the product directly. Have the space at least the dust’s
diameter apart. Use a fan for the duct that considered the ventilation resistance of the duct.
