※1… Performance (cooling capacity, chilled water flow rate) indicates the values at an ambient wet-bulb temperature of 27°C.
※2… Please adhere to the specified chilled water flow range. Insufficient flow may lead to freezing damage or clogging due to dirt accumulation, while excessive flow may cause corrosion due to the impact of flow velocity.
※3… In cases where a high-pressure gas manufacturing notification is required under the High-Pressure Gas Safety Act, please submit the necessary documents to the prefectural governor.
※4… The spray water replenishment volume indicates the value under the conditions of an ambient wet-bulb temperature of 27°C, a chilled water inlet temperature of 30°C, and a chilled water outlet temperature of 25°C (with a fourfold concentration blowdown).
※5… Electrical characteristics (power consumption, operating current) indicate values under conditions of an ambient wet-bulb temperature of 27°C, a chilled water inlet temperature of 30°C, and a chilled water outlet temperature of 25°C. Additionally, the transformer capacity and wiring capacity should be at least 1.2 times the power consumption and operating current to account for variations in usage conditions.
※6… The operating noise level represents values measured outdoors in an open area with minimal reflections (A-scale). In actual installation conditions, surrounding reflections may increase the noise level by approximately 3 dB(A).
※7… When requesting optional features, specifications should generally be provided at the time of ordering the main unit.
※8… These are recommended optional features for enhanced safety and functionality.
