The DCM2x machine does not have a piercing facility built in.
Therefore, when using aluminium capsules, they will require manual
piercing before use. A manual piercing device is included in the
accessories of the DCM2x machine but if you require one then it can
be obtained free of charge by contacting Dualit on 01293 652500.
Generally, the standard extraction time will fall between 15
seconds and 35 seconds. However, that is not exact as certain
factors such as coffee grind, tamping etc will have an effect. It
also depends if the extraction time has been altered.
