15.2 DRAINING CONDENSATE FROM THE OIL TANK
If the compressor work cycle contemplates long pauses during which the machine cools down, a certain
amount of condensate may collect in the oil tank. This happens, for example, when stopping overnight
or at weekends.
The condensate must be drained off every 50 hours or every week. This operation may be performed
only when the machine is cold, that is when it has been switched off for at least 8 hours.
