BEFORE YOU USE
Before using your new coee brewer for the rst time,
or if the machine has not been used for some time, we
recommend rst rinsing the water receptacle. Fill the coee
brewer with cold water and operate once or twice without
any coee.
POWER SUPPLY CORD
The short power supply cord is provided to reduce risks
resulting from becoming entangled in or tripping over
a longer cord. If an extension cord is used, the marked
electrical rating of the extension cord must be at least as
great as the rating of the coee brewer. The extension cord
must be a grounding type 3 cord.
The extension cord should be arranged so it doesn’t drape
over the counter or table top where it can be pulled over by
children or tripped over.
IMPORTANT: This coee brewer is equipped with a special
cord and plug, which in case of damage should be replaced
by a matching cord and plug. This can be obtained from
your Moccamaster service point.
ENVIRONMENTAL RECOMMENDATIONS
• Please discard the lter and coee grounds by
disposing of them in an organic waste container or
compost heap. If not available, you may dispose of
lters and grounds in normal household waste.
• For environmental concerns, please recycle responsibly.
Do not throw away the appliance with the normal
household waste, but hand it in at an ocial collecting
point for recycling. By doing this, you help preserve the
environment.

Filter Holder
The Moccamaster CD(T)-Grand lter holder has two setting: Open – Closed.
This option will allow for overflow if not watched closely!
The Moccamaster manual-adjust lter holder has three
settings:
• Open For brewing a full pot of coee, 6-10 cups.
This setting manually allows for normal
water ow over coee grounds.
• 1/2 Open For brewing a 1/2 pot of coee (2-5 cups) or
for use with brewing tea. This setting manually
slows the drip to allow for longer saturation
time.
• Closed Stops ow of coee if you want a quick
cup before brew cycle is complete (NOT
recommended). This setting manually stops the
ow to allow for a longer saturation time. This
option will allow for overow if not watched
closely! This setting also stops coee drips at
end of brew cycle for emptying the brew-basket.
Automatic Drip-Stop System
• The lter holder for models KBG, KBGT, CD, CDGT, GCS is
equipped with an automatic drip-stop system. The lter holder
will close automatically if the coee pot is removed. For this
reason it is always important to make sure that the jug and lter
holder are in the right position.
Auto-shut-off system
• In all models the main heating element is switched o when
the brewing ends. On models provided with an Auto-o
switch, the hotplate will be automatically switched o
after 40 minutes.
Hot-Plate Temperature Switch
• Glass jug models:
The hot-plate temperature switch is explained with a
full circle which maintains a holding temperature 80-
85°C for 6-10 cups and a 3g-circle which maintains the
holding temperature for less than 6 cups.
• Not all models are provided with this selection switch.
Locking the footplate in place (Thermo brewers only)
• Tilt coee brewer backwards slightly.
• Hook footplate’s vertical rim into the cut away opening, then
lower brewer. Footplate is now locked in place.
• Place the thermos on the footplate, so it presses the white
button on the inner base.
• The orange warning light will be on to indicate correct
placement of the thermos.
Mixing lid
• The glass jug with the mixing lid and the “Brew-Thru-Lid” for
the thermos, makes stirring of the coee unnecessary before
serving resulting in a warmer, pre-mixed brew.
Brew-Thru-Lid
• Scientically designed for minimum heat loss and maintains
perfect temperature while brewing.
• Mixes coee automatically while brewing.
• Simply brew and pour - do not remove lid.
• Easy to clean.

DIRECTIONS FOR USE
1. Power switch should be in the off position.
2. Position multi-hole outlet pipe as shown in the diagram.
· Attach smoothly to the gasket at top of the cold water reservoir.
3. Fill cold water reservoir to the desired level, with fresh cold water.
· Put cold water reservoir lid back in place.
· Reservoir is marked with the number of cups:
1/4 litre of water (2 cups).
· Reservoir Grand models has a mark for 1,8 litre of water (15 cups).
4. Place filter in the filter holder.
· Place a standard #4 white paper lter into the lter holder.
· Place a coee lter 250/110 into the lter holder (1,8 ltr.).
5. Add the appropriate amount of coffee.
· The ECBC approved standard for the perfect cup is 60 grams of coee
per litre water, 75 grams for full 1,25 litre brew.
6. Place the filter holder on the bracket (if present), position outlet
pipe over centre of the filter holder.
· Slide the manual drip-stop system into the open (normal amounts of
coee) or half-open (small amounts of coee).
· CAUTION: lter holder will overow in a closed position.
· K/H models: Place the lter holder onto the glass jug.
· Put lter holder lid back in place.
· CAUTION: Scalding may occur if any of these parts are removed
during brew cycle.
7. Glass jug placement:
· Place glass jug, with lid or lter holder, on the hot plate.
· Place thermos, with the“Brew-Thru-Lid” in brew position beneath
the lter bracket. (Thermos should be placed to depress the white
button).
· We recommend rinsing the thermos with hot water to prevent loss of
temperature.

21
8. Switch the power switch to the “on” position.
· Thermos model: The orange light will illuminate when the thermos is
placed properly against the white button.
· Glass jug models with a hot-plate adjustable switch:
· Turn the switch for the hotplate to the
highest setting,
· Turn the switch to the lower setting if
you would like to keep smaller amounts
of coee warm for a brief period.
9. The brew process will quickly begin; water will be brought to boil,
rising through the brewer across the outlet-pipe and into the filter-
holder. Brew process is complete in 4-6 minutes, with a temperature
of 92-96°C.
10. We recommend disposing of coffee grounds once brew cycle is
complete.
· For models with adjustable lter-holder; Move the slide to closed
position prior to emptying.
11. The brewer should be switched off after use.
• Thermos models;
· The heating element is not receiving power unless the water reservoir
is lled with water, engaging the oat- switch, and the white button
is depressed; the only power consumption is at the power switch itself,
resulting in a very energy-ecient brewer.
• Glass jug models:
· Should be turned o when hot-plate use is no longer desired.
· Optional Auto-o models will automatically shut o in 40 minutes.
Now enjoy a perfect cup of coffee, brewed to industry standards with
your new Technivorm moccamaster!
Coee tastes best immediately after brewing!

TROUBLE SHOOTING
CLEANING & MAINTENANCE
Basic Cleaning
Before cleaning, remove plug from the socket!
• Clean the brewer regularly on the outside with a moist cloth and wipe
dry. After each use, hand wash the jug, thermos and lter holder with
mild detergent. Glass jug or thermos are not dishwasher safe. Coee
oil stains in thermos may be removed using the special “Coee server
cleaning tablet”, available at Moccamaster dealers and in our web
shop at www.moccamaster.eu.
• Do not submerge brewer in any liquid
Cleaning the brewer (inside).
• The brewer needs to be cleaned regularly.
• If used daily it needs to be cleaned every two weeks.
Descaling Your Brewer
• Regular descaling is necessary. We recommend descaling after 100x
coee making, or after a packet of lter paper. For descaling we
recommend Durgol.
• Do not use (organic) descaling agents based on citric acid, which
results in a permanently unpleasant coee taste because the citric
acid reacts chemically with the copper heating element.
Anti-Frost Protection and Extended Storage Guidelines.
• Turn the brewer o and remove the electrical plug from outlet.
• Remove multi-hole outlet pipe.
• Empty any remaining water within brewer by holding it upside down
over the sink.
• Replace the multi-hole outlet pipe before using the brewer again.
