Cleaning the machine
Description
The drain valve is a motor-operated diaphragm
valve, which ensures rapid machine emptying
by its opening on a large cross-sectional surface
area. Its design is self-clearing, which eliminates
the need for lint filters.
The main valve components are:
• motorwithgear
• acme-threadedplungerrodwithplungerand
return spring
• rubberdiaphragm
• connectionsforwaterlling,overllingand
drainage.
In the open position, the valve is de-energised.
The plunger rod is thus screwed down to its
lowest position by the return spring. The di-
aphragm is compressed, forcing the piston
downwards and opening the valve.
When the motor is activated and begins to rotate,
the plunger rod is screwed upwards via the gear,
the diaphragm is compressed, forcing the plung-
er upwards, and the valve closes.
The overfilling connection is connected to the up-
per half of the washing drum, and the water and
suds are led directly to the waste outlet, should
the inlet valves or level control cease to function.
The connection for water filling as well as a
nipple for ceonnection of the sensing line for the
level control are located on the riser to the wash-
ing drum.
