Miele PWM 514 EL Installations Plan page 31

Make sure that you only drill through the first panel (I) as there is a
deflecting panel (II) 10 mm behind it.
Connections 3 to 12 are provided for liquid detergent. High-pressure
dispensing systems with water injection must not be connected to
these connections. The connectors are sealed and must be cut to the
diameter of the hose with a small saw before they are connected.
If opened connectors are no longer required, they must be resealed
using a suitable sealant (e.g. silicone).
External dispensing pumps are connected and calibrated via the
Connector Box, which is available as an option.
A flowmeter or flow sensors can also be connected for monitoring the
dispensing quantity precisely.
Connections for level monitoring are available for every agent dis-
pensed.
