<Table 3.2>
*1 Piping to Expansion vessel is not included in this value.
*2 The environment must be frost-free.
*3 Cooling mode is not available in low outdoor temperature.
If you use our system in cooling mode at the low ambient temperature (10°C or below), there are some risks of plate heat exchanger breaking by frozen water.
