LED Economy cycle (4)
This LED is only relevant in units that are equipped with the optional dewpoint-sensing
control. The diode lights up when the dryer is switched on and in the standby phase and no
regeneration air is required.
Oil indicator
The dryer is equipped with an oil indicator. The indi-
cator allows for periodic measuring of the residual oil
concentration in the purifi ed compressed air.
The residual oil content should only be measured at
set intervals, and the needle valve (1) at the indicator
should be closed during normal operation.
For detailed instructions on the measuring procedure
for residual oil, please refer to the respective section
in the maintenance instructions, page 33.
