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 personnel is not authorised to do this and will
not take any responsibility for the installation.
a) Electric supply
The connection is dependent on the type of machine and its
technical specifications. Voltage must correspond with the data
indicated on the nameplate. The customer must provide separate fuse protection for the supply line. Connection should to
be via a sokket which must have a fault-current protection
switch. In case of permanent connection a switch with at least
3 mm power line separation should be provided to guarantee
an all mains power disconnection.
b) 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.
c) Water outlet (does not apply for machines type M)
All machines are equipped with a connection piece at the water
outlet which can be loosely affixed to a drain pipe together with
the supplied hose.
Water filter
Upon request we install water treatment equipment in all our
coffee machines. These water filter systems reduce scale buildup considerably and improve the quality of the fresh water.
Wall mounting
For wall mounting special wall brackets can be supplied with
machines type A. Instructions for assembly are supplied with
the machine.
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
쎲 Fold the embossed surfaces. Now insert filter bag into the
filter (10) 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 filter paper type Pa 202 S. Order no. 14576.
Filtering with machines type M
(Manually operated machines without firmly attached water
supply)
쎲 Remove the lid (7) of the water container and fill in fresh,
cold water with a jug.
쎲 The measuring range depicted on the jug indicates how
much fresh water is required for a certain amonut of coffee.
쎲 Please make sure that the lid is always inserted on the
glass jug as otherwise temperature losses may occur.
쎲 Switch machine on with On/Off (6). The lower warm holder
(12) is automatically switched on as well.
쎲 The indicator lamp (2) remains illuminated as long as water
flows into the filter.
쎲 The instantaneous water heater switches off automatically
after the filtering process has finished.
쎲 The coffee outlet of the filter can be closed and thus drip-
ping 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.
쎲 Switch on the machine by pressing On/Off switch (6). The
lower warm holder (12) is automatically switched on as well.
쎲 Pre-select the quantity to be filtered by adjusting the
quantity selector.
쎲 Start the filtering process by pressing button (4). The
indicator lamp remains illuminated as long as water flows
into the filter.
쎲 After the pre-selected quantity has run through the
instantaneous water heater is switches off automatically.
