Technical description
ACT ES 20 – 500 27 – EN
7.13 Electronic drainer
This drainer consists of a condensate accumulator where a capacitive sensor continuously checking liquid
level is placed: as soon as the accumulator is filled, the sensor passes a signal to the electronic control and
a diaphragm solenoid valve will open to discharge the condensate. For a complete condensate discharge
the valve opening time will be adjusted exactly for each single drain operation. No condensate strainers are
installed. No adjusting is required. A service valve is installed before the electronic drain in order to make
check and maintenance easily.
At dryer start-up verify that this valve is open.
