olume of sanitary water circuit, primary DHW circuit (from 3-way valve to confluent point with heating circuit), piping to expansion vessel, and expansion vessel are not included in this value.
*2
The environment must be frost-free.
*3
See outdoor unit spec table (min, 10
°C
). 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 damages by frozen water
.
*4 For the model without booster heater and immersion heater
, the maximum allowable hot water temperature is [Maximum outlet water of outdoor unit -3
°C]. For the maximum outlet water of outdoor unit, refer to outdoor unit data book.
*5
Do not fit immersion heaters without thermal cut-out. Use only Mitsubishi Electric service parts as a direct replacement.
