OPERATING INSTRUCTIONS (ENGLISH)
To operate hot water boiler and the coffee brewing machine properly and safely, read the following
instructions carefully.
INTRODUCTION
These machines, models B5-HW, B10-HW and B20-HW are combined hot water dispenser and coffee
brewing machines, with connection to the water mains. The machines are electronically controlled. The
hot water system mainly consists of a water reservoir with heating elements. In the water dispenser the
water is kept at a previously determined temperature. The water will be heated when the water dispenser
is switched on. Via taps (no. 15, fig. 1) the hot water can be tapped for a cup or a jug of tea.
Once the water in the reservoir is at the correct temperature, the temperature of the water drawn off will
always be correct when the dispenser is being used. The reservoir is only refilled when all the water
present is at the desired temperature. When the temperature drops too far as a result of additional cold
water, the refilling procedure is stopped. The water is first heated before proceeding further.
The coffee brewing machine works with a flow-trough heater. Through the outlet in the swivel-arm hot
water is led 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 taken via the drip free taps. 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.

OPERATION
When using the machine keep the warnings
from the INTRODUCTION in mind.
THE COFFEE BREWER
1. Put the plugs of the containers into the
sockets of the column.
2. Turn the coffee brewer on by switch no.
13.6 (fig.1) and the container by switch no.
8 (fig.1). The indicator lights in the switches
will light up.
3. Take the cover from the filter unit, place a
paper filter in the unit and moisten it.
4. Put the right amount of ground coffee into
the filter. The added spoon can contain
about 40 grammes.
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 over the
opening in the filter cover (see fig. 3).
7. Press the selection button 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. After 1 minute
an acoustic signal will sound three times to
indicate that all coffee has been drained
from the filter pan.
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 OF THE
COFFEE BREWING SYSTEM
When the electro magnetic valve is opened for
more than 60 seconds, the running programme
will be inhibited.
In this case the coffee brewing system must be
turned off by switch 13.6 and the cause of the
disturbance should be removed. (Check if the
sieve in the el. magn. valve is blocked, or
whether the water supply is blocked in any other
way). When the cause has been taken away the
system can be turned on again and the program
can be restarted by pressing a start button.
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 taken
away, contact your service engineer or your
dealer.

THE HOT WATER DISPENSER
1. Set switch 13.7 (fig.1) in the "on" position. The
indicator light in the switch and the green and
red pilot lights (no. 13.1, 13.2, fig.1) will light
up. The hot water dispenser will now be filled
automatically. The water will be heated to ca.
95 0C. It takes some time, depending on the
version, before the reservoir is filled and the
water is at the desired temperature. Than the
red light goes out.
2. Hot water can now be drawn out of the tap.
When the water level in the reservoir falls, it
will automatically be refilled and the water
will be heated.
3. When the pilot light indicates that the
temperature is too low, do not tap water
until the pilot light goes out.
OVERFLOW PROTECTION DEVICE OF HOT
WATER SYSTEM
The hot water system is equipped with an overflow
protection device. When the second highest
electrode does not function properly any more,
which might be caused by calcium deposits, the
top electrode will touch the water and this will
cause the hot water system to be turned off.
The indication light "In operation" (13.1) will start to
blink.
Turn the system off by switch 13.7, and take some
water from the system. Remove the cause of the
fault, e.g. by scraping the calcium deposits from
the second highest electrode and rinse it
thoroughly.
Turn the system on again with switch 13.7.
Does this fault occur again, than contact your
service engineer or dealer.
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 containers 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 detergent in hot water (min. 85°C).
Ca. 1 sachet per 5 litre.
2. Place the parts to be cleaned in the solution.
3. All the parts now should be left to soak in the
solution for about 10 to 30 minutes.
4. After being soaked rinse everything
thoroughly with clean hot water.
5. If there are coffee stains at the interior of the
containers, fill the containers with 5, 10 or 20
l. hot water (by pushing the button).
6. Dissolve sachets of detergent in it. (One
sachet per 5 litres). Before filling, place the
empty filter unit on top of the container to
prevent splashing.
7. The solution should be left to soak for 10 to
30 minutes.
8. Now empty the container and rinse the
interior thoroughly with hot water, to repeat
the procedure for making 5, 10 or 20 l. hot
water twice. Do not forget to empty the
container in between.
Now the machine is ready for normal use.
Descaling
COFFEE BREWER
During use of the machine scale will accumulate.
The machine is equipped with a descaling
indicator (no. 13.5, fig.1) which will come into
operation when a predetermined amount of
water has passed trough the flow-trough heater.
When the descaling indicator is blinking the
descaling procedure should be carried out,
to ensure the proper functioning of the device.
We advise for this purpose RENEGITE, a
descaling agent which we have tested
ourselves. (Read the instructions on the packet
as well):
1. Position an empty container properly under
the outlet of the swivelarm.
2. Press the selection button for 1l. (B5-HW),
2.5 l. (B10-HW) or 5 l. (B20-HW).
3. After the delivery of hot water stops, the
container can be drawn.
4. Dissolve the descaling agent in lukewarm
water. Use the measuring jug for accuracy.
For B5 and B10-HW: use 50 grams in 0,75
litre of water. For B20-HW: use 100 grams
in 1,5 litres of water.
5. Take the plug out of the inlet on top of the
column. Pour the descaler solution in via
the opening next to the swivelarm using the
added funnel (fig 8).
6. Press the button for 1 l., 2,5 l. or 5 l. again.
7. Wait for about 3 to 5 minutes after the
acoustic signal to allow the solution to fulfil
its function.
8. After these minutes press the section button
for 4 l., 7,5 l. or 15 l.
9. When the indicator light of the button goes
out the container must be emptied. The

7
descaler solution can be disposed of
through the normal drain system.
10.Now press the selection button for 5 l., 10 l.
or 20 l. After the indicator light of the button
goes out, the container must be emptied
again.
11.Repeat instruction 10 once or twice, to be
sure that everything is rinsed thoroughly.
The filter unit can be rinsed separately.
12.Set the counter of the descaling indicator to
zero. (See chapter "To set the descaling
indication at zero" page 8)
Fig. 8
HOT WATER DISPENSER
Under normal operating circumstances, calcium
deposits will also appear in the hot water
dispenser. It must be regularly descaled in order
to function properly. When the hot water
dispenser has switched itself off, it is most
advisable to give it a really good descaling. Pay
special attention to removing the calcium
deposits from the two highest electrodes.
(Scrape them off with a small knife.) For
descaling purposes we advise RENEGITE, a
descaling agent which we have tested
ourselves. The following instructions are based
on the use of 100 gr of RENEGITE (read the
instructions on the packet as well).
The descaling procedure is as follows:
1. If the system is switched OFF and the water
is cold, drain off as much water as possible
via the hot water tap.
2. If the system is switched ON it must be
switched off and as much hot water as
possible drained. Cool the system by
pouring 3 litres of cold water into the
reservoir and draining it off again.
3. Dissolve 100 grms. descaling agent in ± 1
litre lukewarm water.
4. Pour the solution carefully into the hot water
reservoir.
5. Switch on the appliance again.
6. When the reservoir has been filled up to the
next to the highest electrode (see A, fig. 9),
wait ten minutes.
7. Meanwhile, draw off a cup of descaling
solution every minute from the usual hot
water taps (thereby giving the taps a good
descaling as well.)
8. Switch off the appliance once the ten
minutes is up and draw off as much solution
as possible via the usual tap.
9. Then pour ± 3 litres cold water into the
reservoir (to cool the system quickly).
10.To drain the reservoir quickly, the
instructions 11 through 14 can be followed.
11.At the front of the machine is a drain
situated (no. 12, fig. 1).
12.This drain can be opened by turning the key
(at the left hand side) a quarter of a turn
with a screwdriver or coin (the slot goes
from the vertical into the horizontal
position).
13.Drain the contents of the reservoir.
20.CAUTION ! Wear good protective gloves
when draining the descaling solution in this
way.
14.Close the drain by turning the slot in the
vertical position.
15.Now pour ± 5 litres of water into the
reservoir. Make sure it doesn't overflow.
16.Drain as much water as possible via the
usual hot water taps (thus rinsing the taps
as well).
17.Repeat operations 15 and 16 at least twice,
but now with ca. 4 l. water (the reservoir
may not overflow).
18.Switch on the water dispenser.
19.Before using the hot water for consumption,
it is advisable to rinse the taps well once
more by first drawing off another litre or so
of hot water via the hot water taps.
DRAIN
In case the drain is blocked, deblock it with the
aid of the cleaning spring. Therefore put the
spring into the drain and push it up and fro.
CAUTION !
- Leave the reservoir uncovered during the
entire descaling process.
- Prevent the descaling agent from touching
the top electrode.
- Due to the violent reaction which occurs
when the descaling agent comes into
contact with the calcium deposits, the water
may touch the topmost (safety) electrode,
thus switching off the system. In that case,
switch the system off manually using switch
(13.7, fig.1). Wait ca. 20 seconds and switch
the system on again in order to continue the
descaling process.
