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.

The water temperature of the hot water

dispenser can also be adjusted. Put the

adjusting screwdriver supplied in the adjusting

hole en turn it to the right for a higher

temperature, to the left for a lower temperature.

CAUTION! Adjust the temperature only when the

reservoir has been filled up to the next to the

highest electrode (A, fig. 9).

The water in the reservoir should not be allowed

to boil.

From the dash underneath the adjusting hole

and the graduation scale on the screwdriver, one

can see how far it has been turned.

Turn the adjustment 1 or 2 stripes and check the

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

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.
