Connection and assembly
All MELITTA appliances are supplied ready for connection. Prior to
installation all necessary connections which are to be provided by
customer must be easily accessible within a radius of 1 mtr. This
preliminary work must be carried out by licensed experts and must
be according to current rules and regulations. MELITTA service per-
sonnel is not authorised to do this and will not take any responsibi-
lity for the installation.
Electric supply
The connection is dependent on the type of machine and its techni-
cal specifications. Voltage must correspond with the data indicated
on the nameplate. The customer must provide separate fuse pro-
tection for the supply line. Connection should to be via a sokket
which must have a fault-current protection switch. In case of per-
manent connection a switch with at least 3 mm power line separati-
on should be provided to guarantee an all mains power disconnec-
tion.
Water supply
(does not apply for machines type M)
In accordance with regulations a tap with a non-return valve is to be
installed at an easily accessible place. A special connection hose is
supplied with the machine and for safety reasons this hose must not
be shortened at assembly. Water pressure must be at least 2 bar. If
water pressure is more than 6 bar then a pressure reducing valve
must be installed between the main tap and the machine.
The supplied fine sieve is to be inserted between the tap on site and
the connection hose.
Water outlet
(does not apply for machines type M)
All machines are equipped with a connection piece at the water out-
let which can be loosely affixed to a drain pipe together with the sup-
plied hose.
Water filter
Upon request we install water treatment equipment in all our coffee
machines. These water filter systems reduce scale build-up consi-
derably and improve the quality of the fresh water.
Initial operation
Always ensure that the machines are placed on an even surface as
otherwise exact dosage is not possible.
For the initial operation before making the first coffee we strongly
recommend to run the machine with water only. The MELITTA
System and its principle of unpressurized filtering can generally
guarantee for a high rate of extraction i. e. making full use of flavour
and aroma substances of the ground coffee. But the best possible
quality of the beverage can only be achieved if the quantity of water
is in correct proportion to the amount of coffee powder.
This proportion is not always constant though. Amongst other things
it depends on the brand of coffee used and also on the required
quantity of coffee. If only 2 cups of coffee are to be filtered the 8 gr.
coffee powder per cup are necessary whilst if larger quantities of
coffee are to be prepared then sometimes 5 gr. coffee per cup can
be sufficient.
This means that the quality of the coffee is maintened although less
coffee powder is needed to prepare larger quantities of coffee.
A few trial filtering sessions might be to be find out the best dosage
results.
Preparing the filter
b Fold the embossed surfaces. Now insert filter bag into the filter
(6) and fill with coffee powder or tea. Recommend quantity:
Coffee = approx. 5 - 7 gr. per cup or approx. 35 - 50 gr. per ltr.
Tea
= approx. 1,5 gr. per cup or approx. 5 -12 gr. per ltr.
Use MELITTA filtering paper type Pa 202 S. Order no. 14576.
Filtering with machines type M
(Manually operated machines without firmly attached water supply)
b Remove the lid of the water container and fill in fresh, cold water
with a jug.
b The measuring range depicted on the jug indicates how much
fresh water is required for a certain amonut of coffee.
b Please make sure that the lid is always inserted on the glass jug
as otherwise temperature losses may occur.
b Switch machine on with On/Off switch (3). The lower warm hol-
der (9) is automatically switched on as well (171 M/A, 172 M/A,
173 MW/AW).
b The indicator lamp (2) remains illuminated as long as water
flows into the filter.
b The instantaneous water heater switches off automatically after
the filtering process has finished.
b The coffee outlet of the filter can be closed and thus dripping
prevented by pressing the drip prevention lever.
Filtering with machines type A
(Automatic machines with firmly attached water supply)
Make sure that prior to putting the machine into operation the tap for
water at the water supply pipe is open.
Please also make sure that the lid of glass jug is always inserted as
otherwise temperature losses may occur.
b Switch on the machine by pressing On/Off switch (3). The lower
warm holder (9) is automatically switched on as well (171 M/A,
172 M/A, 173 MW/AW).
b Pre-select the quantity to be filtered by adjusting the quantity
selector (8).
b Start the filtering process by pressing button (7).
b After the pre-selected quantity has run through the instanta-
neous water heater is switches off automatically.
170 MW, 173 MW hot water unit
Putting into operation
b Remove lid from the water container and fill approx. 3,7 ltr. fresh
water into the empty tank.
b Switch on the machine by pressing On/Off switch (12).
b After approx. 14 minutes the boiler has reached working tem-
perature. As soon as the indicator lamp (11) ceases to burn the
machine is ready for operation and hot water can be taken.
Hot water extraction
b As long as the green indicator lamp (11) is not burning, hot
water can be discharged via faucet (13).
b The water boiler has to be filled again after approx. 1,8 - 2 ltr. of
water have been discharged.
b The indicator lamp then lights up but ceases to burn again after
a heating up period of approx. 7 minutes. Now hot water can be
discharged again.
