NOTES
1 Nominal cooling capacities are based on: indoor temperature 27°CDB/19°CWB * outdoor temperature 35°CDB * refrigerant piping length:
5m * level difference: 0m.
2 Nominal heating capacities are based on: indoor temperature 20°CDB * outdoor temperature 7°CDB/6°CWB * refrigerant piping length
5m (horizontal) * level difference 0m.
3 Capacities are net, including a deduction for cooling (an addition for heating) for indoor fan motor heat.
4 Units should be selected on nominal capacity. Maximum capacity is limited to peak periods.
5
6 The sound power level is an absolute value indicating the ’’power’’ which a sound source generates.
7 Energy label: scale from A (most efficient) to G (less efficient).
8 The energy label Directive 2002/31/EC will enter into force once the relevant measurement standard will be published in the European
official Standard.
9 Annual energy consumption: based on average use of 500 running hours per year at full load (= nominal conditions)
The sound pressure level is measured in an anechoic room at 1m distance from the unit. It is a relative value, depending on the distance
and acoustic environment. For measuring conditions: please refer to item 8 of this chapter.
