- ※1 Performance (Cooling capacity, Chilled water flow rate). The values are based on a dry-bulb ambient temperature of 35°C.
- ※2 High-Pressure Gas Safety Act Applicable Classification. No high-pressure gas manufacturing notification is required under the regulations of the High-Pressure Gas Safety Act.
- ※3 Refrigerant Charge Amount. The specified amount is based on standard specifications. Additional charging may be necessary under certain design conditions to ensure performance. (The final charge amount is indicated on the nameplate.)
- ※4 Electrical Characteristics (Power Consumption, Operating Current). The values are based on conditions of 35°C dry-bulb temperature, 35°C chilled water inlet temperature, and 25°C chilled water outlet temperature. Transformer capacity and wiring capacity should be at least 1.2 times the indicated power consumption and operating current.
- ※5 Internal Control Circuit. Operates on DC24V (Some models support DC12V, DC5V).
- ※6 Noise Value (Measured at a Distance of 2m and Height of 1.5m). The stated value represents the measurement in an environment without reflective surfaces (A-weighted sound scale).. In actual installation conditions, the surrounding environment may cause variations of approximately ±3 dB(A). During summer, to protect the equipment, the upper rotation speed of the blower fan may temporarily increase, which can result in higher noise levels.

- 1.The values for power consumption and operating current are based on the conditions of 35°C ambient dry-bulb temperature, 35°C chilled water inlet temperature, and 25°C chilled water outlet temperature. Power consumption and operating current may vary depending on operating conditions.
- 2. If the voltage drop exceeds 2% over the maximum wiring length, the internal wiring regulations require increasing the wire thickness.
- 3.The minimum wire thickness applies to metal conduits (wire), synthetic resin conduits, floor ducts, and cable wiring. For metal conduits and synthetic resin conduits, the specification is based on three wires housed within the same conduit.

⚠ Safety Precautions
- Regarding the Use of the Chiller Tower The chiller towers listed in this catalog are for general industrial use.
- Before Use Please read the instruction manual carefully before use and operate the unit correctly.
- Regarding Installation Installation should be performed by a qualified professional. Improper installation may result in water leakage, electric shock, or fire hazards.
- Regarding Installation Location Do not install the unit in locations where flammable gases may leak or where ignitable materials are present. Avoid areas where flammable gases may be generated, accumulate, or stagnate, and areas where carbon fibers or metal dust are floating, as they pose risks of fire or explosion.
