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 = 8.4 Cooling Capacity x 0.8.

3.2.2 Location
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
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 ducts diameter apart. Use a fan for the duct that considered the ventilation resistance of the duct.

Example of temperature offset
The discharge temperature of the circulating fluid is 30 o C, but the fluid temperature in the
customers device is 29 o C because of heat radiation during sending of the fluid.
MODE Explanation
MODE1
Control the temperature so that the discharge temperature of the circulating fluid is circulating fluid set temperature + offset temperature. Circulating fluid temperature indicates the circulating fluid discharge temperature.
MODE2
Control the temperature so that the discharge temperature of the circulating fluid is circulating fluid set temperature. Circulating fluid temperature indicates the circulating fluid discharge temperature + offset temperature.
MODE3
Control the temperature so that the discharge temperature of the circulating fluid is circulating fluid set temperature + offset temperature. Circulating fluid temperature indicates the circulating fluid discharge temperature - offset temperature.
OFF Control the temperature so that the discharge temperature of the circulating fluid is circulating fluid temperature set value.
Example of MODE 1
When the offset temperature is 1 o C, the thermo-chiller controls the temperature at 31
o C (circulating fluid
set temperature + offset temperature.) Even if the discharge temperature is 31 o C, the circulating fluid
temperature is 30 o C at the customers device because of 1
o C of heat radiation during sending of the fluid.
Circualting fluid display temperature and communication data is 31 o C.

Pump operation mode
4. Pump operation mode can be set up.
Pump operation mode can be selected from the following three modes:
Pressure control modeOperates to maintain the circulating fluid discharge pressure at the set pressure.This mode is set by default.
The pressure might not rise to the set pressure if the piping resistance in the users device and piping is too small.
Flow control modeOperates to maintain the circulating fluid flow rate at the set flow rate. (However, CH1 flow rate serves as a rough indication.)
The flow rate might not reach the set flow rate if the piping resistance in the users device and piping is too large.
Pump output setting modeOperates to maintain the pump output (rotation) at the set output.
About the control function of circulating fluid discharge pressure This is a function to control the pump output to maintain the circulating fluid discharge pressure within the set pressure. This function is Disabled by default. If this function is Enabled, the control pressure set by this function gets priority over the pressure, flow rate and output set by the pump operation mode. [ ] is displayed on the upper screen when the pump discharge pressure is controlled during operation. (Refer to 5.4.1 Operation condition display on home screen.)
