If the dryer has not been used for more than 3 months, refer to section Initial start-up. In all other
cases, proceed as follows:
1. Cut off the air supply from the compressor towards the dryer by closing the inlet valves.
2. Close the outlet valves between the dryer and the air consumer.
3. Start the compressors and slowly open the inlet valve.
4. Ensure the dryer is powered on.
5. Gradually open the air outlet valves.
