Dispensing pump connections

Up to 12 dispensing pumps can be connected to the washing ma-
chine.
Dispensing pump connections on the back of the machine
Connections 1 and 2 are provided for viscous agents and can also be
used for high-pressure dispensing systems with water injection. The
dispensing systems must be fitted with a separate drinking water
safety mechanism in accordance with Regulation 4 of The Water Sup-
ply (Water Fittings) Regulations 1999 EN 61770 and EN 1717. The
maximum flow rate is 1500 ml/min with a maximum flow pressure of
300 kPa.
These connectors are sealed and need to be drilled open using a
8 mm drill bit before connecting.
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.
