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.
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
5
and acoustic environment. For measuring conditions: please refer to item 8 of this chapter.
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)

WARNING
NOTES
DON'T TOUCH CAPACITOR, EVEN AFTER
PLUG-OFF ( DANGER OF ELECTRIC SHOCK)
The capacitor retains high
voltage even after the plug-off.
For your safety, be sure to wait
at least 5 minutes. after plug
off and use a tester to confirm
the voltage between connector
CN301 and CN302 is less than DC
10V before start servicing.
