Maximum water inlet temperature ............................ 80 °C
Maximum working pressure ....................................... 8 bar
Operating Voltage ..............................230V(±10%) ~ 50Hz
Room Temperature ................................................. 0÷45°C
Room Humidity .................................................<85% U.R.
To prevent the formation of condensation on the exterior of
the unit while the fan is operating, the average water
temperature should not drop beneath the limits shown in the
table below, determined by the thermo-hydrometric ambient
conditions.
These limits refer to unit operation with fan at minimum speed.
In case condensation is formed on the exterior of the unit
if cold water circulates through the coil while the fan is off
for prolonged periods of time, it is advisable to fit the
additional three-way valve.
