HRL Series 3.2 Installation
3-5
 Thermo-chiller installation at high altitude of 1000 meters or more
Due to the lower air density, the heat radiation efficiencies of the devices in the product will be lower at an
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 = “9.4 Cooling Capacity” x
0.8.
 Installation/Operation in accordance with the UL standard
The product cannot be used in the environment shown below:
● Environment at an altitude of 2000 meters or more
● Environment at a pollution degree of 3 or more
