NOTES

1Nominal cooling capacities are based on: indoor temperature 27°CDB/19°CWB * outdoor temperature 35°CDB * refrigerant piping length: 5m * level difference: 0m.

2Nominal heating capacities are based on: indoor temperature 20°CDB * outdoor temperature 7°CDB/6°CWB * refrigerant piping length 5m (horizontal) * level difference 0m.

3Capacities are net, including a deduction for cooling (an addition for heating) for indoor fan motor heat.

4Units should be selected on nominal capacity. Maximum capacity is limited to peak periods.

5The 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.

6The sound power level is an absolute value indicating the ’’power’’ which a sound source generates.

7Energy label: scale from A (most efficient) to G (less efficient).

8The energy label Directive 2002/31/EC will enter into force once the relevant measurement standard will be published in the European official Standard.

9Annual energy consumption: based on average use of 500 running hours per year at full load (= nominal conditions)
