Dispenser Pump Connections - Miele PWM 920 EL Installation

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 simultane-
ously.
If the slope for drainage is extremely steep, the piping must be
vented 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 re-
sult of undersized pipework can result in faults occurring during pro-
gram sequences, which will result in fault messages appearing in the
machine display.
 Outflowing suds can be as hot as 203°F (95°C). Danger of injury
by burning!
Avoid direct contact.

Dispenser pump connections

Up to 12 dispenser pumps can be connected to the washing ma-
chine.
Dispenser 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 equipped with a separate drinking water
safety feature in accordance with EN 61770 and EN 1717. The maxi-
mum flow rate is 1,500 ml/min with a maximum flow pressure of
43 psi (300 kPa).
These connectors are sealed and need to be drilled open using an
8 mm drill bit before connecting.
