OPERATING INSTRUCTIONS (ENGLISCH)
To operate the coffee brewing machine properly and safely, read the following instructions
carefully.
INTRODUCTION
These machines, models B5, B10, B20 and B40 are coffee and tea brewing machines, with
connection to the water mains. The machines are electronically controlled and work with a flow-
through heater. Through the outlet in the swivel-arm hot water is guided into the filter unit where
it filters through the coffee.
The swivel-arm is equipped with a safety device, so when the swivel-arm is not in the right
position above the filter unit the hot water stops running. When filtered the coffee is collected in
the coffee container from which it can be dispensed via the drip free tap. To keep the coffee in
the containers at the right temperature heating elements are built in. The container heaters can
be turned on and off independently of the rest of the machine by a switch at the front of the
container.

some components will get very hot.
2. If the appliance is unused for a longer
period of time, it is advisable to discon-
nect the electricity and close the water
supply.
3. Under normal circumstances, a small
quantity of water always remains in the
appliance. Please keep this in mind if it
is to be exposed to temperatures below
0 °C.
4. Do not use sharp objects to operate the
buttons.
5. If all water has been removed from the
machine, the "Initial Operating
Procedure" will have to be repeated.
6. Stay with the appliance during mainte-
nance operations (such as descaling).
7. When working with strong cleaning or de-
scaling agents, it is most advisable to
wear safety goggles (face protector) and
gloves.
8. After working with strong cleaning or
descaling agents, be sure to wash your
hands.
9. Never syringe the column or the container
until they are wet and never immerse the
appliance in water.
10.Prevent spillage of the descaler solution
on to the outside of the machine, this
can cause permanent damage to the
exterior surface of the machine housing.
In the event of a spillage, wipe area
affected dry, whilst observing the safety
regulations as given in the Users Instruc-
tions. Directly afterward the area must
be cleaned thoroughly.
11.Make sure that all repairs are carried out
by qualified technicians.
12.When the appliance has to be opened

INSTALLATION AND INITIAL OPERATING
PROCEDURE
When installing the appliance, keep the
warnings from the INTRODUCTION in mind.
* Installation
1. Locate and fix the column using 4 or 6
bolts on a strong, flat and horizontal
base (see enclosed assembly drawing).
Ensure that when the machine is
located in this position, it can be
connected to the water supply and the
electrical services.
2. Connect the hose to the machine and
the water mains and connect the cable
to the electric supply according to the
attached instructions.
3. Place the containers with the filter units
on top, on the base and put the plugs in
the sockets (no. 12, fig.1) on the
column.
4. Position the swivelarm in the correct
position, this is with the outlet over the
opening in the filter cover (fig. 3).
5. Use the funnel supplied to pour water
into the de-scaling aperture (fig. 8). The
B5 and B10 models take 1,5 litres, the
B20 takes 3,5 litres and the B40 4,5
litres.
6. The containers and filter units should be
rinsed with hot water. Therefore press
the selection button for the highest
quantity (no. 13.1, fig. 1) The indicator
light in the switch will be illuminated.
The container will now be filled with hot
water. When the program stops the
indicator light in the switch goes out and
after 1 min. the acoustic signal will
indicate completion of the brew cycle.
7. Position the swivel-arm above the next
container with filter unit and push the but-
ton again. When the containers and filter
units are cleaned, the containers can be
emptied. A tip for draining: see chapter on
maintenance/cleaning, point 6.
The machine is now rinsed and ready for
use.
Connecting the cable
Dependent on the voltage and the supply
system, the machine has to be connected
according to one of the drawings below:
230-240 V~ (3-core cable) Fig. 4
230-240 V3~ (4-core cable) Fig. 5
400-415 V3N~ (5-core cable) Fig. 6
The apparatus is easy to adapt to other
voltages. Consult your dealer.

OPERATION
When using the machine keep the warnings
from the INTRODUCTION in mind.
1. Put the plugs of the containers into the
sockets (no. 12, fig. 1) of the column.
2. Turn the container heating on by switch
no. 8 (fig. 1). The indicator light in the
switch will light up.
3. Take the cover from the filter unit (no. 4
+ 5, fig. 1), place a paper filter in the
unit and moisten it.
4. Put the right amount of ground coffee
into the filter.
5. Put the cover back on the filter unit and
place it on top of the container.
6. Turn the swivel arm with the outlet (no.
2, fig. 1) over the opening in the filter
cover (see fig. 3).
7. Press the button (no. 13.1 till 13.4, fig.1)
for the desired amount of coffee. The
indicator light in the button will now
illuminate and the machine will start
brewing the coffee.
8. When the coffee brewing process is
completed, the supply of hot water
stops and the indicator will go out.
9. A new brew of coffee can now be made
in the second container. Turn the
swivelarm above the second container
and repeat the above procedure.
OVERFLOW PROTECTION DEVICE
When the electro magnetic valve is opened
for more than 60 seconds, the running
programme will be inhibited.
The cause of the problem should be
removed. (Check if the sieve in the electro
magnetig valve is blocked, or whether the
water supply is blocked in any other way).
When the cause has been corrected the
system can be turned on again and the
program can be restarted by pressing one of
the push buttons (1 to 4). The program will
be restarted.
PLEASE NOTE!
Keep in mind that the programm will start
from the beginning. When the used coffee
container is already partly filled and the
same programm is started this might cause
the container to flow over.
When the fault occurs again or can not be
corrected, contact your service engineer or
your dealer.
MAKING TEA
Naturally you can use this equipment to
make tea. It is a simple operation, using a
tea filter and a tea attachment, which can
be supplied as accessories.
Use 4 grams of tea or one tea bag per litre
of water.
If the apparatus is regularly used to make
tea, the following two points have to be
taken into account:
1. A container used for making coffee
should not be used for making tea
because remains of coffee will
contaminate the tea. So reserve one
container for the making of tea.
2. Remains of tea combined with
atmospheric oxygen can affect the
lifespan of your tea container. So
always empty the container completely
after use. Remove the remains of tea
thoroughly using warm water and a
brush.
3. Use a tea-container (VHG-T) to
maintain a higher tea temperature.
MICROFINE FILTER
Instead of filter paper it is also possible to
use the microfine filter, which can be
ordered as an extra.
To obtain the best results with the microfine
filter, you must take the following points into
consideration:
1. After each coffee cycle rinse the filter
pan thoroughly to prevent a build-up of
coffee deposits.
2. Rinse the filter pan at the end of the day
or evening and wash it. The filter pan
with the microfine filter can be put in
the washing up machine.
3. Clean the filter pan with the microfine
filter once a month with "cleaner" (see
MAINTENANCE chapter on cleaning).
If you do not clean the filter pan as
described above the coffee will not taste as
good as it should (it will be too strong or
taste of stale coffee).

MAINTENANCE
Warning !
Stay with the machine while carrying out
maintenance work like descaling. Also keep
the other safety regulations in mind as given
in INTRODUCTION-Warning !
Cleaning
The outside of the machine and the contai-
ners can be cleaned with a damp cloth. The
filter units can be washed up in a normal
way. The interior and the tap of the
containers can be rinsed with hot water. If
coffee stains can not easily be removed it is
best to give a treatment with our detergent
CLEANER. Cleaning the removable parts
with this detergent is simple (also read the
instructions on the package):
1. Dissolve the contents of 1 sachet of de-
tergent in ca. 5 l of hot water (min.
80°C).
2. Place the parts to be cleaned in the
solution. All the parts now should be left
to soak in the solution for about 10 to
30 minutes. After being soaked rinse
everything thoroughly with clean hot
water.
3. If there are coffee stains at the interior
of the containers, fill the containers with
hot water (by pushing the button for the
largest quantity, no. 13.1, fig. 1).
4. Dissolve detergent in it (1 sachet per 5
l). Before filling, place the empty filter
unit on top of the container to prevent
splashing.
5. The solution should be left to soak for
10 to 30 minutes.
6. Tip for getting rid of the cleaner solution:
slide a hose pipe of sufficient length
and 1.8 cm diameter onto the drainage
tap (no. 8, fig. 1). Hang the end of it in
the sink or in a bucket. Now empty the
container and rinse the interior thor-
oughly with hot water, to repeat the
procedure for making hot water once or
twice. Do not forget to empty the
container in between.
Now the machine is ready for normal use.
Descaling
During use of the machine scale will
accumulate. In order to ensure that the
apparatus functions correctly it must be de-
scaled regularly (at least once every six
months, in very hard water areas once a
month). We advise for this purpose RENE-
GITE, a descaling agent which we have
tested ourselves. (Read the instructions on
the packet as well)
Collect the following together before you
start de-scaling the machine: bucket (if
there is no water drainage available),
sufficient length of hose pipe with a
diameter of 1.8 cm, funnel, measuring jug,
gloves, face guard, damp cloth and the
Renegite de-scaler.
1. Position an empty container with filter
unit properly under the outlet of the
swivelarm. Place a damp cloth on the
rotary head to prevent any de-scaling
solution splashing.
2. Slide the hose pipe onto the container
drainage tap (no 8, fig. 1). Put the other
end of the hose pipe in the bucket or
sink.
3. Press the button for the smallest
quantity (no. 13.4, fig.1). This is
neccesary, to be sure the water
reservoir is emptied to the lowest
electrode. Therefore the reservoir will
not overflow.
4. After the delivery of hot water stops,
(the indicator lamp in the selector
switch goes out) the container can be
emptied.
5. Dissolve the descaling agent in
lukewarm water. Use the measuring jug
for accuracy.
For B5 and B10: use 50 grams in 0,75
litre of water. For B20: use 100 grams
in 1,5 litres of water. For B40: use 150
grams in 2,5 litres of water.
6. Take the plug out of the inlet on top of
the column. Pour the descaler solution
in via the opening next to the swivelarm
(see fig. 8) using the added funnel.
7. Press the button for the smallest
quantity (no. 13.4, fig. 1).
8. After the indicator light of the push
button goes out, wait for about 5
minutes to allow the solution to fulfil its
function.

6
9. After this time press the button for the
next to largest quantity (no. 13.2, fig. 1).
10.Wait till the indicator light of the button
goes out. This means that water has
stopped flowing from the rotary head.
11.Remove the damp cloth. Rinse it
thoroughly.
12.Check whether the swivel arm also
needs de-scaling. Be careful! Hot water
has just been flowing through it, so the
swivel arm will be hot. Remove the
swivel arm by moving it clockwise and
ant-clockwise alternately and pulling it
upwards at the same time. Check if
there is any scale in it. If so, plunge the
rotary head in the de-scaling solution in
the sink or bucket. Add 50 to 100 grams
of de-scaler to it. Leave the rotary head
in the solution for 3 to 5 minutes. Take
it out of the solution and rinse
thoroughly. Use a torch to check that all
the scale has been removed from the
riser pipe (see fig. 9). If it still contains
scale, repeat the de-scaling procedure
from point 5 to point 14.
13.Place the swivel arm back correctly on
the riser pipe.
14.Drain the container. The descaler
solution can be disposed of through the
normal drain system.
15.Now press the button for the largest
quantity (no. 13.1). After the indicator
light of the button goes out, the
container must be emptied again.
16.Repeat the instruction 15 once or twice,
to be sure that everything is rinsed
thoroughly. The filter unit can be rinsed
separately.
Now the machine is ready for normal use.
When de-scaling twin-column models you
can use first one and then the other
container with filter unit so that the scale is
removed from both.

COLUMN WITH COMPUTRONIC PANEL
OPERATION OF THE TIMER
Using the timer, up to four operational
periods per day can be set, within which the
machine will prepare coffee or tea. When a
quantity is programmed with the selector
buttons outside the set periods or blocks,
the machine will only begin to work when
the next block is timed to switch on. In this
way, for example, the machine can be set in
the evening to prepare coffee or tea the
following morning.
The heating system for the coffee contai-
ners fitted on the hot water column will also
only be switched on during the set blocks
(the switch on the container will have to be
in the "on" position). A selector switch (3,
fig. 10) can be used to switch off the timer
manually. Operation of the selector buttons
can be blocked with the key-operated switch
(15, fig. 10), thus preventing unauthorised
alteration of the set quantities. This does not
block or protect the timer's setting facility.
In the following section, the operation of the
extra possibilities offered by the timer and
the key switch will be discussed in detail.
The timer
The timer blocks are set in ten-minute
steps, thus establishing the minimum
interval and duration times. The maximum
block duration time is 24 hours (from 00:00
h to 24:00 h); overlapping blocks (including
those which begin and end at the same
point in time) are seen as one block. The
block time settings are indicated on the
display above the adjustment knobs; Ù=
switch-on time, Ú= switch-off time 14 C
and D(fig. 10).
The on/off status of a given block is indica-
ted by the visibility of the horizontal lines
corresponding to the lines between the red
and blue adjustment knobs (E, F, G & H,
fig. 10).
