Dispensing Pump Connections - Miele PWM 920 EL/RH Installationsplan

A vented drainage system is vital for unimpeded drainage.
If several machines are connected to a single drain pipe, this
should be sufficiently large to allow all machines to drain simultan-
eously.
The appropriate Miele installation kit (mat. no.: 05 238 090) is avail-
able to order from the Miele Customer Service Department or your
Miele dealer for venting an HT DN 70 pipe.
If the slope for drainage is extremely steep, the piping must be ven-
ted to prevent formation of a vacuum in the machine's drainage
system.
Slow or obstructed drainage or a backup of water in the drum as a
result of undersized pipework can result in faults occurring during
programmes, which will result in fault messages appearing in the dis-
play.
 Outflowing suds can be as hot as 95 °C. Danger of burning!
Avoid direct contact.

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.
