*ErP in accordance with EN 14825, EN 12102-1, EN 14511, EN 16147. The energy efficiency provided may not correspond to the actual energy once installed in a building, as the efficiency is influenced by other factors such as heat loss in the distribution system and the capacity of the products in relation to building size and characteristics. *Hydraulic unit: Sound pressure level at 5m from the appliance, 1.5m off the ground, open field directionality 2 / Outdoor unit : Sound pressure level at 5m from the device, halfway between the ground and top of the outdoor unit, open field directionality 2. **The EN 12102-1, sound power level is a laboratory measurement of the emitted sound power. It does not correspond to a measurement of the perceived sound power. **** Calculation in accordance to MIS:MCS 020 Issue 1.3. Thermal and acoustic performances are measured with 7.5m length refrigerant lines. ***** Fuse rating for Outdoor Heat Pump Unit
