11. VISUAL PROGRAMMING OF BEVERAGE PORTIONS
Chapter 14.1 explains how to re-program all parameters
(volume, strength, temperature) for all beverage buttons.
Re-programming the cup size for coffee and milk can also be
done during beverage preparation as follows.
READY.
• Push and hold the beverage button you want to re-program
until display shows
ENOUGH COFFEE? or ENOUGH MILK?
This way you can make sure your (cappuccino) cup is
filled with the desired volume of (milk and) coffee.
Example:
Visually re-programming the Cappuccino button (Fig. 4).
READY.
• Prepare the Cappuccino Systems (milk container etc.) to make
a cappuccino and place your cappuccino cup under the
Cappuccino System (Fig. 16).
• Push and hold the Cappuccino button until display shows
ENOUGH MILK?
• When the desired amount of milk and milk froth is in your cup,
push the Cappuccino button again. The display now shows
ENOUGH COFFEE?
• When enough coffee has been added to your frothed milk
push the Cappuccino button again. The display briefly shows
OK then READY.
The next time you push the Cappuccino button, the C9 OT
will produce that amount of milk and coffee.
12. WATER CARE
The C9 OT works with: • tap water • bottled water • distilled
water. We recommend using tap water or bottled water. Distilled
water has no minerals and does not improve the taste of coffee.
Water that is heated inside the machine leads to calcium deposits.
Tap water has a varying degree of water hardness (chapter 12a).
Most bottled water has a low level of water hardness.
IMPORTANT: do not use carbonated water or any other liquid in
the water tank.
You have the following options to take care of the water.
• Decalcifying System (chapter 17.1). The machine is factory
pre-set to automatically remind you to decalcify.
• Clearyl Water Filter Cartridge (chapter 13a).
12a. WATER HARDNESS MONITOR
Your C9 OT is set to a water hardness of 10ºdH and will auto-
matically indicate when it is time to perform a decalcifying cycle.
You can change the water hardness setting from 1º to 30ºdH. If
you are not sure about the hardness of your water, ask your local
water company for the "Water Hardness in Grains." The machine
displays the water hardness in the German hardness scale which
is a bit different from the American "Grain" scale (see chart
below). You can also use the water hardness indicator strip
("Aquadur" in Welcome Pack) to determine the water hardness:
• Insert the strip for one second into the water you want to
use. Shake off any access water and wait for one minute.
One or more sections of the indicator strip will turn reddish.
• Change the water hardness setting according to the table
below.
