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. For a facility with 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. For a facility with a small installation area that cannot 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. Ensure the space is at least
the duct’s diameter apart. Use a fan for the duct that considers the ventilation resistance of
the duct.

Do not install in a location which can be subjected to any of the
conditions in “3.2.1 Environment”.
Radiates heat from the air vent of the cooling fan.
If the product is operated with insufficient air ventilation, the internal
temperature can exceed 45
o
C, which can cause and affect the
performance and life of the product. To prevent this, ensure that
suitable ventilation is available (see below).
