*1 Heating performance measurement conditions: outside air temperature 7 or 6 °C, water supply temperature 30 °C, outlet temperature 35 °C, refrigerant piping length 7.5 m (no height difference), capacity 97%, COP 95%, operating noise +3 dB
*2 Cooling performance measurement conditions: outside air temperature 35 °C, water supply temperature 12 °C, outlet temperature 7 °C, refrigerant piping length 7.5 m (no height difference), capacity 97%, COP 95%, operating noise +3 dB
*3 • The remote controller should be shipped with the hydro unit.
• Use two
*4 The outdoor unit operating noise is measured at the point of 1m away from the unit back surface center and 1m high from the ground. The hydro unit operating noise is measured at the point of 1m away from the unit front surface center.
The value of the operating noise varies depending on room structure where the unit is installed.
*5 Do not leave the hydro unit at 5 °C or below.
*6 Check the water piping for leakage under the maximum operating pressure.
