Depending on the installation height of the Thermo-cooler and/or the cooled substrates, circulating fluid may overflow from the tank lid or overflow outlet. In particular, avoid overflow from the lid of the built-in tank by installing with a height difference of 10 m or less. Be sure to pipe the overflow outlet to a wastewater collection pit, etc. 27 Related Technical HED HEB HEC HRW HRZD HRZ HRS HRG Products Data Series HRG Specific Product Precautions 3 Be sure to read this before handling.

When using clear water or deionized water • Replacement of clear water or deionized water Failure to replace the clear water or deionized water can lead to the development of bacteria or algae. Replace it regularly depending on your usage conditions. • Tank cleaning Consider whether dirt, slime or foreign objects may be present in the circulating fluid inside the tank, and carry out regular cleanings of the tank. 2. When using ethylene glycol aqueous solution Use a concentration measurement device to confirm that the concentration does not exceed 15%. Dilute or add as needed to adjust the concentration. 2. Check the water quality of facility water. Regarding the water quality standards for facility water, refer to “Temperature Control Equipment Precautions”. 1. Inspect the circulating fluid. 1. Remove the panel and inspect if there is abnormal leakage from the pump’s mechanical seal. 2. Leakage amount of a mechanical seal Leakage of the mechanical seal cannot be completely avoided due to its construction (rotating machine). Although this amount of leakage is stipulated as 3 (cc/h) or less (reference value) according to the JIS standard, replace the mechanical seal when the amount of leakage is 0.3 (cc/h) or greater.
