z Location that is subjected to static electricity, or conditions where static
electricity can discharge to the product.
z Location that is subjected to strong high frequencies raditation
(microwaves).
z Location that is subjected to potential lightening srtike.
z Location where the product is affected by strong vibrations or impacts.
z Condition that applies external force or weight causing the product to be
damaged.
z Location without adequate space for maintenance as required.
z Location that is exposed to splash of the water that is higher than IPX4.
z Refer to the below for product installation or operation in an environment
temperature of 10
o
C or less.
z Location at altitude of 3000m or higher (except during product storage and
transport). Refer to the below for details.
„
Thermo-chiller installation in high altitude of 1000 meters or more
Because of lower air density, the heat radiation efficiencies of the devices in the product will be
lower in the location at altitude of 1000m or higher. For this reason, the maximum ambient
temperature for the thermo-chiller operation and the cooling capacity will be reduced.
For product installation at a place of high altitude of 1000 meters or more, select a thermo-chiller
of the applicable capacity referring to the table below.
1. Max. ambient temp.: Use the product in lower ambient temperature than
the described value at each altitude.
2. Cooling capacity correction coefficient: Coefficient to calculate the
cooling capacity at each altitude
For the product operation at an altitude of 1800 meters,
“the cooling capacity at an altitude of 1800 meters” =
“the cooling capacity at an altitude of 1000 meter” x 0.8.
„ Installation/Operation in an ambient temperature of 10
o
C or less
Use ethylene glycol solution at a concentration of 15 % for the circulating
fluid.
