INSTALLATION, OPERATION
AND MAINTENANCE GUIDE
WATER CASSETTES
Above mentioned technical data are calculate at the following operating conditions:
- Maximum fan speed
- Standard unit without ducts
(A) Cooling: inlet water temperature: 7 °C; Outlet water temperature: 12 °C; Inlet air temperature: 27 °C w.b. 19 °C d.b.
(B) Heating: inlet water temperature: 70 °C; Outlet water temperature: 60 °C; Inlet air temperature: 20 °C
(C) Heating: inlet water temperature: 50 °C; Same water flow as in cooling; Inlet air temperature: 20 °C
(D) Air flow and fan speed: fancoil performances with cleaned filter
(E) Sound power level: Sound power measured following ISO 23741
(F) Electrical data referred to the maximum available speed
