5. On air-cooled compressors, check the setting of circuit breaker (Q15). Also check that the
switch on the circuit breaker is in position I.
6. Fit air outlet valve (AV). See section Introduction for the location of the valve.
Close the valve.
Connect the air net to the valve.
On compressors equipped with a dryer bypass, fit the air outlet valve to the dryer bypass
pipe.
7. Connect the condensate drain outlet(s) to a drain collector.
See section Condensate system.
The drain pipes to the drain collector must not dip into the water. If there is a risk for
freezing, the pipes must be insulated.
For draining of pure condensate water, install an oil/water separator which is available from
Atlas Copco as an option. See section OSCi
8. For compressors with a DD or a DD and PD filter: connect the automatic drain of the filters
to a suitable drain collector.
9. On water-cooled compressors, drain valves, shut-off valves and a regulating valve should be
fitted by the customer in the cooling water piping.
10. Provide labels, warning the operator that:
• The compressor may automatically restart after voltage failure (if activated, consult
Atlas Copco).
• The compressor is automatically controlled and may be restarted automatically.
