Part 5 Field Settings and Test Operation
Refrigerant recovery/vacuuming mode
In order to achieve a free pathway to recover refrigerant out of the system or to remove
residual substances or to vacuum the system it is necessary to apply a setting which will
open required valves in the refrigerant circuit so the recovering of refrigerant or
vacuuming process can be done properly.
Default value: 0
To activate this function, change [2-21] to 1.
To stop the refrigerant recovery/vacuuming mode, press the RETURN (BS3) button. If
the RETURN (BS3) button is not pressed, the system will remain in refrigerant
recovery/vacuuming mode.
Automatic night-time low noise setting and level during night-time
By changing this setting, you can activate the automatic night-time low noise
operation function of the unit and define the level of operation. Depending on the
chosen level, the noise level will be lowered (3: Level 3 < 2: Level 2 < 1: Level 1).

external signal is sent to the unit, this setting defines the level of night-time low noise
that will be applied (3: Level 3 < 2: Level 2 < 1: Level 1).
This setting will only be effective when the optional external control adaptor
(DTA104A61/62) is installed and the setting [2-12] is activated.
