Draining the cooling oil (closed floor pan - stationary machine):
Compressor cooling oil and engine coolant drain lines are led to a central point outside the ma‐
chine on stationary machines and machines with closed floor pan. The cooling oil is drained via
pipes which are screwed into the drain openings of the oil separator tank and the compressor block
and are closed with a shut-off valve. The pipes are sealed with a screwed sealing plug at the drain
end.
