*1. Values at operating use area temperature 25℃, circulating water temperature 20℃, and circulating water rated flow rate.
*2. If you want to maintain the electrical conductivity of circulating water with ion exchange resin, etc., please contact our sales staff.
*3. Based on chiller temperature gauge display values under constant load, surrounding temperature of 25℃, circulation water temperature of 20℃, and circulation water flow at rated volume.
*4. Value calculated based on circulation water flow of 4ℓ/min. To prevent pump breakdown, avoid running the chiller with circulation water flow below 4ℓ/min.
*5. Excluding the protruded part.
*6. Maintain power supply voltage within ±10% of rated voltage.
*7. Values measured with a 1m face, 1m height, and no load stability.
*8. External temperature sensor not included. The user prepares the external temperature sensor.
*9. Errors are recorded in 5 second intervals from approximately 1 minute before.
