Initial Operation; Setting The Current Time; Coffee Preparation - WMF Lumero Operating Manual

Initial operation

Prior to the first use and after the device has not been operated for an extended period of time, run
a brew cycle with fresh water without coffee grounds. To do so, fill the tank to no higher than the
10-cup mark (version with glass jug) or to the 8-cup mark (version with thermal jug), as otherwise
the jug can overflow.

Setting the current time

After connecting the mains plug to a socket, the time appears on the display. The standard time is set
as 12:00. You can correct the set time at any time by pressing the Timer symbol
seconds. The dots between the hours and the minutes start to flash. Press the + and - symbols to set
the correct time. Confirm the time by pressing the Timer symbol
after approximately 15 seconds the standard time is displayed.
Note: The time must be reset after a power failure or after the mains plug has been unplugged.

Coffee preparation

For easy filling of the water tank you can remove it. The lid on the water tank can be removed. Only
pour cold water into the tank. The water level indicator is for the amount of fresh water that is
needed to brew the desired number of cups per 125 ml coffee.
In order to pour in the ground coffee, open the swing filter by pressing the release button on the
water tank. Place the paper filter of the 1 x 4 size into the filter, but fold the stamped edge before
doing so. The paper filter should not protrude over the edge of the filter. If necessary, push it down
slightly with your hand.
Add the required amount of ground coffee. Depending on your personal taste, use approximately 5–7
g of medium-fine ground coffee per cup. If it is ground too finely, the filter can overflow.
Then close the swing filter. It will audibly click into place.

Information about the Cromargan® thermal jug
(only version with thermal jug)
Important: Do not use the jug to keep milk products or baby food warm due to the risk of the build-
up of bacteria. Do not heat the jug up in the microwave or the oven. Do not use the jug to store or
transport carbonated drinks. After cleaning the jug, rinse
it carefully with clear water.
The jug is designed as a serving jug and best keeps the content warm when it is full. The time the
content is kept warm may be reduced significantly if the jug is only partially filled or almost empty. It
is best to rinse the jug with hot water before preparation.
For technical reasons, the seal from the brewing lid is not 100% tight so that it can be easily opened,
even after the coffee cools down. Therefore, never lie the jug down to transport it, otherwise coffee
could spill out. To close, tighten the lid only slightly. Only use the filled jug standing upright.
To pour, press the push button on the handle. Press it once to open the jug; you can now pour out
the coffee. To check if the jug is open, there is a white mark on the top of the jug lid. Press the push
button on the handle again to close the jug.
