The acoustic data are related to standard conditions (source on a reflective surface in free field) in referable and reproducible oper
-
ating conditions. The environment and the installation conditions, as well as the operating modes, can alter the sound emissions. All
data with the exception of Lw_tot are provided for illustrative purposes only and can not be used for forecasting purposes or for the
verification of binding limits.
Reference conditions: source-side heat exchanger input/output water temperature 30/35°C; user-side heat exchanger input/output
water temperature 12/7°C; unit operating at rated capacity, without any option.
Lw:
Values taken by measurements made in accordance with standard ISO 3744 and the Eurovent certification programme, where
applicable Lw_tot is the only binding value.
Lp:
Binding values starting from noise power levels referred to a distance of 10 m from the unit; source installed on a reflective sur
-
face and in ideal free field conditions with directivity factor Q=2. No Lp value is binding.
Noise data refer to the standard conditions illustrated above, in reference and reproducible operating conditions.All data, excluding
Lw_tot, are provided for the sake of exemplification and must not therefore be used for forecasting purposes or for the verification of
mandatory limits. With special reference to noise emissions, the Manufacturer takes liability for their conformity, limited to the declared
Lw_tot value. Any and all other Manufacturer’s liability for the impact of such emissions in relation to the location of the machine and
other conditions related to machine installation is excluded. Any assessment concerning these conditions falls within the area of com
-
petence of the plant designer and/or the fitter.
