NTRODUCTION
To achieve a lower noise level, the units are equipped with inverter
fans. In addition, it is possible to run the unit in low noise mode during
periods that the unit can be used with lower cooling capacity and
cooling efficiency.
■
When the unit is running in normal mode, the fans of the air
cooled condenser will be controlled as to achieve a high
pressure of 13.0 bar (EWAP*)/9.0 bar (EWAD*).
■
When the unit is running in low noise mode, the fans of the air
cooled condenser will be controlled as to achieve a high
pressure of 22.0 bar (EWAP*)/13.0 bar (EWAD*).

NOTE
In case more cooling capacity is required during
low noise mode, it is possible to lower the high
pressure value of 22.0 bar (EWAP*)/13.0 bar
(EWAD*) via the service menu. In this case
however, noise reduction will be less.
