 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
2. Cooling capacity correction coefficient: Coefficient to calculate the cooling

At an altitude of 1800 meters = Cooling capacity 8.4 x 0.8.
Less than 1000m
1000 m or more - Less than 1500 m
1500m or more - Less than 2000m
2000m or more - Less than 2500m
2500m or more - Less than 3000m
 Installation/Operation in accordance with the UL standard (for the optional UL
compliant model)
For operation of the UL compliant model (available as an option,
HRR012/018/024/030-A/W-10/20-U) in UL compliant conditions, 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
