Notes
(1) Operation range heating (outdoor unit): range increase by support back-up heater
(2) See operation range drawing: range increase by support booster heater or backup heater
(3) The sound pressure level is measured via a microphone at a certain distance from the unit. It is a relative value depending on the distance and acoustic environment. Refer to
sound spectrum drawing for more information.
(4) Minimum Ssc value: Equipment complying with EN/IEC 61000-3-12: European/International Technical Standard setting the limits for harmonic currents produced by equipment
connected to public low-voltage systems with input current \>16A and 75A per phase
