Operation
Condensate containing fine oil droplets flows via a strainer (5) through filter (3), in which the droplets coalesce
into larger drops. The condensate is then led to vessel (1) where the oil rises due to the difference in specific
mass. The vessel is provided with two separated outlets: one for condensate (7), which is led outside the
bodywork, and one for the separated oil (8), which is caught in collector (4).
5.2 Operating and maintenance instructions
Safety precautions
Before carrying out any maintenance, repair work or adjustments, proceed as
follows:
•
Stop the compressor.
•
Close the air outlet valve and open, if provided, the manual condensate drain valve.
•
Close the air outlet valve and press the test button on top of the electronic water drain
until the air system between air receiver and outlet valve is fully depressurized.
•
Press the emergency stop button.
•
Switch off the voltage.
For detailed instructions, see Problem solving.
The operator must apply all relevant Safety precautions.
Operating instructions
Inside of OSD
• Before starting, check that vessel (1) is filled. If necessary, gently pour water into filler pipe (2) or vessel
(1) until it flows through tube (3). Reinstall the cover.
• During operation of the compressor, an oil layer is built up above the water level in vessel (1). Depending
on the capacity of the compressor and its operation cycle, the humidity of the inlet air and the oil content
of the compressed air, it may take several weeks or months before an oil level is observed in collector (4).
• Regularly check that vessel (1) is filled. If necessary, gently pour water into filler pipe (2) or vessel (1)
until it flows through tube (3). Keep the cover installed during operation.
