(*)
Weight for model with pump and tank.
(**) If the water volume of the system is below the minimum, a buffer tank must be installed.
(***) If the water volume of the system is above the maximum, an additional expansion vessel is required.
(****) Starting current accounting for the electronic starter (current limiter).
- Cooling capacity: outside air temperature 35°C, water temperature 12°C - 7°C.
- Sound pressure level measured in compliance with the standards ISO 3741 - ISO 3744 and EN 29614-1
- Sound pressure measured at a distance of 10 metres and 1.5 metres from the ground in free field conditions (fan end).
- The maximum power consumption is the power consumption of the mains power supply required for the unit to operate.
- The maximum input current is the current level at which the internal protective devices of the unit are tripped. It is the maximum
allowable current per unit. This value must never be exceeded and must be used to size the line.
