The KN-8828B-2K gives the user the option to easily and quickly roast using an automatic mode.
The “Auto” mode supplies a roasting curve that can begin with as few as three presses of a single button. It
can be modified to run for a programmed amount of time or a programed temperature and will automati-
cally eject the beans when either parameter is reached. It also allows time to be changed at any time during
the roast or for the target temperature to be modified. The roast can be stopped at any time the user desires.
If this is your first time roasting coffee we highly recommend starting with the AUTO function.
Plug the machine into an appropriate outlet and
POWER
becomes illuminated.
Press the button next to
POWER
to begin.
“AUTO” is the default display.
Select Auto Mode by pressing the button next to

“PH” flashing in the Target Time display area indicates that the roaster is in
“Preheat” mode. When the roaster signals you with a series of beeps (at 167 F.) it is
time to pour in the green coffee beans.
Use the
SELECT
Arrow key to highlight the parameter you wish to modify.
At any time, if you wish to end the roast, simply press the
EJECT
button and
the machine will eject the beans and begin the cooling mode.

To begin roasting with the default parameters of “AUTO” mode, press

once more and the roasting process begins.
MODIFYING ROAST PARAMETERS
Either before the roast begins or after the Pre-Heat (PH) cycle ends, various roasting parameters
can be changed. Before beginning the roast, only Target Time and Target Temperature are available to be
modified. During the Roast you can change Fan Speed and Heating Element Power as well.

Here you see the box around the time parameter indicating that it is selected
and displaying Target Time which continuously shows the remaining roast time
before the beans are ejected. Target Time is now ready to be modified.

While the roast is in progress, there are three safety points. The first may occur at 356 F (180 C).
The other two will occur at 395 F (202 C) and 428 F (220 C) if those temperatures are achieved before
the roast ends (see on page 14 for details).
