†
Eurovent-certified performances in accordance with standard EN14511-3:2013.
† † Gross performances, not in accordance with EN14511-3:2013. These performances do not take into account the correction for the proportional heating capacity and power input
generated by the water pump to overcome the internal pressure drop in the heat exchanger.
Condition 1 : Cooling mode conditions, evaporator water entering/leaving temperature 12°C/7°C, condenser water entering/leaving temperature 30°C/35°C, evaporator fouling factor 0 m².K/W.
Condition 2: Cooling mode conditions, condenser water entering/leaving temperature 40°C/45°C, evaporator water entering/leaving temperature 10°C/7°C, evaporator fouling factor 0 m².K/W.
*
In dB ref=10-12 W, (A) weighting. Declared dualnumber noise emissio n values in accordance with ISO 4871 (with an associated uncertainty of +/-3dB(A)). Measured in accordance with
ISO 9614-1 and certified by Eurovent.
** In dB ref 20µPa, (A) weighting. Declared dualnumber noise emission values in accordance with ISO 4871 (with an associated uncertainty of +/-3dB(A)). For information, calculated from
the sound power level Lw(A).
*** Option 257 = Low noise level.
**** Weight shown is guideline only. Please refer to the unit nameplate.
