3.2.2 Location (Required ventilation rate and facility water source)
„ 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 (For air-cooled type)
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.

The water-refrigerated thermo-cooler discharges heat by using facility
water. Therefore, it is necessary to supply facility water from the
source listed in the following table.
Do not install in a location which can be subjected to any of the
conditions in 3.2.1 Environment.
The 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 40

, which can cause an overload or affect
the performance and life of the product. To prevent this ensure that
suitable ventilation is available (see below).
