5) OPERATION for V1 models (for V3 models jump forward to page 8)
Grinding coffee:
Fig 5.1
Before start grinding coffee please spend few minutes to learn and understand the concept of the Titan On
demand grinding controller (fig. 5.1.)
Modes of operation:
The Titan ODG can be operated in 3 different modes. Activating (or deactivating) each one of the modes, is
achieved by single short pressing on the relative mode selector button. Once activated, a green LED will turn on.
Continues mode, while in continues mode pressing longer than 3 sec on continues-mode button will
start the grinder (The relative LED will blink as long as the grinder is running) stopping the grinder by
another short press on continues-mode button.
Single cup mode, while in single cup mode any press on the demand switch (fig 5.2) will activate the
grinder to grind a precisely timed dose (time can be programmed by user) into the filter handle.
Double cup mode, while in double cup mode any press on the demand switch (fig 5.2) will activate the
grinder to grind a precisely timed dose (time can be programmed by user) into the filter handle.

Dose counting LCD:
The Titan ODG V1 grinder is equipped with 3 independent dosing counters.
In order to view the content of each counter, a single press on the counter’s selector will display the
next counter’s content and at the same time the relative counter’s LED will turn on.
2 of the counters are resettable (middle and left most LED); in order to reset each of these 2 counters a
5 sec continues press on the counter selector will zero the relative counter.
On single cup mode each coffee demand will increase the counting on all the 3 counters in 1.
On double cup mode each coffee demand will increase the counting on all 3 counters in 2.
On continues mode the counters are not counting.
Programming grinding time for single and double cup mode:
The grinder was factory set with time values for single and double dose grinding periods. These preset values are
obviously estimated and user should find his own times according the coffee grinding request. In general as the
coarseness setting of grind is coarser the time required to grind same weight of coffee is shorter. Additionally
different type of coffee blends and coffee shops are requiring different dose size for their single and double cups
(6.5gr to 9.5gr per single cup and 11gr to 18gr for double cup). The Titan ODG supports user’s need to modify
grinding time setting frequently.
In order to modify time setting of single cup or double cup mode please follow these steps:
1. Press the desired mode selector button continuously for longer than 3 sec. when in programming mode
the mode selector’s LED blinks.
2. At programming mode LCD display shows your current set time (in seconds and tents of seconds).
3. In order to increase or decrease set time simply rotate the peripheral scale of the knob. Follow the new
time set up on the LCD.
4. When reaching the desired time value press shortly the mode selector button to return to normal working
mode (watch the display is returning to display the counting)
Grinding in continues mode:
The Titan ODG was designed to grind continuously into bags or any other collecting container (for more details also
refer to 2in1 section 6). Nevertheless this grinder was not designed as a pure “bags grinder”. We suggest:
1. Select continues mode button (continues mode LED is turned on)
2. Place the collecting container under the outlet chute (fig 5.4). Press the continues mode button for longer
than 3 sec.
3. The grinder will turn on and the LED will start blinking. Stop the grinding by another short press on
continues mode button.
In continues mode do not grind more than 10kg (20 pounds) of coffee per day.
Grind in intervals of not more than 1 kg (2 pounds) per hour.
When grinding in continues mode, keep the powder outlet top cover open and shake
the bag from time to time. View the free flow of coffee to avoid back logging of the
powder into the grinding chamber. In that case, stop the grinding, use the provided
brush to evacuate the clogged powder into the bag and resume grinding.

Operating intervals:
In order to avoid over heating of grindstones and grinding chamber (resulting unnecessary heating of the
coffee) the manufacturer is recommending using the appliance continuously for short intervals of a few
minutes each. Never exceed 10 minutes of continues grinding (or more than 1.5 kg of coffee beans).
Adjusting coffee grinding
The Titan grinders’ family (Titan I, II) are equipped with the revolutionary patented Bottom-Setting©®™
mechanism with LCD to read the grinding position accurately and constantly. The position of the grinding
setting knob and LCD are on the left side bottom part of the body (see fig. 5.2).
Fig 5.2
The grinding grindstones’ distance was factory pre adjusted to satisfy different common coffee grinds from
fine Turkish coffee powder to coarse filter brewing. This clearance span can be achieved by turning the
grinding setting knob for 12 full turns. Turning the grinding setting knob incrementally counterclockwise (CCW)
will make the grind coarser and turning it clockwise (CW) will make the grind finer. Practically we recommend
making grind changes by turning the knob ¼ turn at a time.
The coarseness setting and accordingly the LCD reading should be performed only when grinder is plugged
to power.
In course of normal usage (and especially if changing setting of the grinder while grinder is unplugged) there
might be a need to recalibrate the digital display to match the actual grinder’s setting
The digital system is including a self-homing (automatic reset). There are 2 possible cases for recalibration.
oCase 1: The display is showing a finer digit than the actual grinding
oCase 2: the display is showing coarser digit than the actual grinding
In both cases start the recalibration by empty the coffee beans from grinding chamber by closing the hopper’s
door and grinding till grind it is empty.
In both cases the recalibration is starting by setting the grinder to finest grinding coarseness by turning the
knob clockwise.
Case 1:
oWhile setting, note that the display will show ‘- - ‘ which is below 0.1, continue to turn the knob till it
cannot be turned any more. Then by turning back the knob counter clockwise the grinder already is
recalibrated and ready for use.
Case 2:
oWhile reaching the point where the knob cannot be turned any more and the display still showing a
number which is greater than ‘0.1‘
oDisconnect the power plug, turn the knob counterclockwise few turns (5-10),
oComplete the recalibration as in Case 1 above.
Test the recalibration by having the grinder plugged to the power, and make few turns coarser and back to
finer make sure that every time at most fine (where the knob cannot be turned any finer) the display is
showing ‘0.1’

6) SAFETY DEVICES
A) Thermal overload protection
In order to eliminate the risk of fire, the motor is equipped with an overheat protection device which will cutoff
the motor’s power supply should it reach a high temperature.
In the event that the thermal protection is tripped as a result of malfunction (e.g.: jammed grindstones, worn
out bearings, foreign object in grinding chamber, etc.) the appliance main switch should be turned off
immediately and the main power plug must be disconnected. For further handling of the device contact your
local service provider, and allow the appliance to cool down before any further maintenance.
In the event that the thermal protection is tripped as a result of a long continuous operation (read section 5,
for operating intervals) allow the appliance to cool down and reset the thermal cutoff protection by
unplugging the main cable from the socket. On the first operation after resetting a tripped overheat
protection device observe the grinding quality and noise level, and if there are any irregularities shut down the
appliance and call a certified technician for a complete analysis of the appliance.
B) Grinding chamber safety switch and hopper fixing screw
The grinding chamber is a hazardous area if the proper precautions aren’t observed. In order to avoid any hand
contact with running grindstones grinding chamber is equipped with a safety switch that can be activated only by a
matching pin on the hopper’s crown (Fig. 4.2) Do not attempt to operate the grinder without the hopper is fully
placed and fixed in its position by hopper’s fixing screw (Fig 4.3).
