  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 (for air cooled type) 
1. For a 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. For    a 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 duct’s diameter apart. Use 
a fan for the duct that considered 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”. 
The air cooled product 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).
