Key features
DC inverter technology and R410A
The MS3 range combines DC inverter technology with R410A refrigerant. For U-18MS3H7HE, the specification table lists a rated cooling EER of 5.15 W/W and cooling power input of 9.7 kW.
Operation at high outdoor temperatures
The catalogue describes MS3 cooling operation at outdoor temperatures up to 52°C DB. Available capacity must be checked with operating conditions and correction factors; the temperature limit does not imply full rated capacity under all conditions.
Flexible system layout
The MS3 range offers space-saving and high-efficiency combinations. The catalogue gives range-level limits of up to 64 indoor units and up to 1,000 m of total piping. These are conditional system limits, not a default capability of every model.
