THERMA V Split Type Hydro Box Unit
Note
1. Due to our policy of innovation some specifications may be changed without notification.
2. Wiring cable size must comply with the applicable local and national codes. And “Electric characteristics” chapter should be considered for electrical
work and design. Especially the power cable and circuit breaker should be selected in accordance with that.
3. Sound Level Values are measured at Anechoic chamber. Therefore, these values depend on the ambient conditions and values are normally higher
in actual operation.
4. Performances are based on the following conditions :
• Cooling : Inlet/Outlet Water Temp. 23°C/18°C, Outdoor Air Temp. 35°CDB / 24°CWB
• Heating : Inlet/Outlet Water Temp. 30°C/35°C, Outdoor Air Temp. 7°CDB / 6°CWB
• Interconnected Pipe Length is standard length and difference of Elevation (Outdoor ~ Indoor Unit) is Zero.
5. This product contains Fluorinated greenhouse gases.
• * : This specification is data when electric heater is not used.
• ** : This information is given as a guideline about the connection of DHW tank.
• *** : This Accessory Kit is required only when you want to user the electric heater function at DHW tank. If not, it’s not necessary. Therma V indoor unit
it self already has electric heater (back up heating) function.
