Installation

NOTICE: It is essential that full voltage and amperage
always be available as it takes full power to grind
coffee.
Please read this manual before operating the grinder.

1. Carefully remove grinder from carton.

2. Place grinder in position on shelf, counter or
other flat surface.

3. Plug grinder into the specified power source.
(Check rating plate on back of unit for
voltage and amperage requirements.) Do
not use an extension cord.

4. Grind a small amount of whole bean coffee
following operating instructions as described
in this manual.

If you need help, call Grindmaster-Cecilware Technical
Service Department for help, [phone] or (800)

Prior authorization must be obtained from
Grindmaster-Cecilware for all warranty claims.

Operation

Your new coffee grinder is easy to operate and
maintain. Before you place it in service, please have all
personnel familiarize themselves with these
instructions. Keep this manual in a convenient place for
ready reference.

How to Operate

1. Fill the hopper with whole bean coffee and

close the lid.

2. Place the brew basket with coffee filter

between brew rails.

3. Push the start button. Grinder will grind a

predetermined amount of coffee, and then
automatically shut off.

4. When grinder stops, remove the brew

basket.

NOTE: If too much or too little coffee is dispensed,
adjust the timer inside the grinder to dispense the
desired weight of ground coffee (see Portion
Adjustment). The grinder is factory set to deliver
approximately 2 ounces of ground coffee. This weight
is approximate, as the density of all coffee beans is not

the same. The only way to ensure the desired portion
is being dispensed is to weigh the coffee after it has
been ground.

NOTE: The grind is factory set to deliver a standard
autodrip grind. The grind texture can be adjusted, if
necessary, to a finer or coarser grind (see Grind

Adjustment).

Helpful Hint

Because of the inherent properties of some
decaffeinated coffee, it may be necessary to dispense
a slightly greater amount to achieve the desired level
of flavor extraction as in regular coffee. This should be
evaluated based on the coffee you use as well as the
brewing equipment used.

Portion Adjustment

This unit utilizes a dual range solid state timer control
to determine the amount of beans ground during each
grind cycle. Changing the timer setting will increase or
decrease the amount of ground coffee dispensed.

The length of time to grind a specified quantity of
coffee is dependent upon the grind setting and the
hardness and size of the coffee beans. The
Approximate Dial Setting Table can be used as a
guide. The final setting will have to be determined by
weighing the coffee dispensed. Once the time has been
established, the grinder will dispense approximately
the same quantity of coffee each time the start button
is pushed. To adjust the portion see Timer
Adjustment.

access panel. Plug unit in.

Grinds

Before shipment, this grinder has been tested with
coffee and has been accurately adjusted to deliver
ground coffee to normal auto drip specifications.
The Grinding Burrs are made of an extremely hard and
wear resistant alloy. From time to time, grind
adjustments (see following instructions) may be
necessary as the burrs wear. If the grind runs coarser
than expected after normal adjustment and the grind
time has increased, the burrs may have excess wear and
should be replaced. New burrs should always be
installed as a pair, never one or the other, as they are
accurately ground and lapped in pairs. Old burrs
cannot be resharpened.
