Procedure
1. Remove the protective cap from the exhaust connection.
2. With vertical installation, connect the exhaust line directly with the exhaust connection.
3. With horizontal installation (180°), connect the exhaust line using an outlet elbow.
4. Route the piping downwards from the vacuum pump, to prevent condensate return.
5. Install a condensate separator if necessary.
