CORETCENCINES 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 4 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.

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 sepa- rate 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-retum valve is to be installed at an easily accessible place. À special connec- tion 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.

Upon request we_install water treatment equipment in all our coffee machines. These water filter systems reduce scale build- up considerably and improve the quality of the fresh water.

For wall mounting special wall brackets can be supplied with machines type A. Instructions for assembly are supplied with the machine.

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 fltering can generally guarantee for a high rate of extraction i. e. ma- king 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 fitered 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 © 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 tr. Tea = approx. 1,5 gr. per cup or approx. 5 -12 gr. per tr.

Use Melitta filter paper type Pa 202 S. Order no. 14576.

Filtering with machines type M

(Manually operated machines without firmly attached water supply)

© Remove the lid (7) of the water container and fill in fresh, cold water with a jug.

© The measuring range depicted on the jug indicates how much fresh water is required for a certain amonut of coffee.

@ Please make sure that the lid is always inserted on the glass jug as otherwise temperature losses may occur.

© Switch machine on with On/Off (6). The lower warm holder (12) is automatically switched on as well.

© The indicator lamp (2) remains illuminated as long as water flows into the filter.

© The instantaneous water heater switches off automatically after the filtering process has finished.

© 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 fimly_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.

© Switch on the machine by pressing On/Off switch (6). The lower warm holder (12) is automatically switched on as well.

© Pre-select the quantity to be fitered by adjusting the quantity selector.

© Start the fiterng process by pressing button (4) The indicator lamp remains illuminated as long as water flows into the filter.

@ Afer the pre-selected quantity has run through the instantaneous water heater is switches off automatically.

193 W / 197 W Maintenance

© Switch on the hot water unit by pressing On/Off switch (14). The indicator lamp is illuminated and the boiler for preparing hot water starts to heatup.

After approx. 14 minutes the boiler has reached working temperature. The indicator lamp (13) ceases to bum and the hot water unit is ready for operation.

Hot water extraction:

Hot water can be despensed via fittings (17) is switch (13) is pressed. Water can be dispensed as long as this switch is operated.

If requested we can supply a screw-on extension for the outlet (17) so that tapping height can be reduced from 185 to 130 mm. Order no. 11628.

Switching off the machine

The machine should be switched off ovemnight and during longer stillstands.

By operating switch (6) the coffee machine unit and the lower warm holder can both be switched off at once.

The top warm holders (8) are switched off with switch (5). The hot water unit of W-type machines is switched off by pressing switch (14)

The facilities provided on site i. e. electric connections and water supply should be switched off if the machine is not to be operated for a longer period of time.

Servicing indicator lamp

A defect within the heating system of the water heater (I. e. excessive build-up limescale) is indicated by the servicing indicator lamp. If this lamp is illuminated the heater is automatically switched off for safety reasons.

Depending on the degree of limescala build-up the heater automatically strats to work again after a break. The total filtering time increases repectively.

Descaling the machine is now urgently necessary and must be carried out as soon as possible as otherwise the builtin machine safety fuse strats to react. If this is the case a servicing engineer must be requested in oreder to restore the working condition of the machine.

Cleaning and maintenance

Attention: The machine should not be put into water for cleaning purposes nor should water be poured or sprayed over the machine. Always pull the main plug out of the socket before starting to clean the machine.

Larger coffee machines used in the field of commercial catering are generally rather expensive and therefore shuld be maintained_properly. Regularly mainained machines not only look better but the coffee made with these machines over à longer period of time is also of better quality.

Melitta can offer a cleaning programme especially designed for these purposes.

Outer cleaning: © Wipe plastic and stainless steel surfaces regulary with a damp cloth. We recommend Swir-EST-care products in spray can for special treatment steel surfaces. Order no. 201025.

Depending on water quality and frequency of use the instaneous water heater must be descaled more or less often (hard water and fréquent use = frequent descaling).

By installng a water filter these service intervals can be in- creased_considerably.

Advise for descaling

© Fill the 2 ltr. jug half full of water and stir-in quick descaling powder with a pplastic spoon (50 - 100 gr. per Itr.) until the powder is completely dissolved.

© Insert filter (10).

Set quantity selector (3) to the smallest quantity.

© Remove the round lid from the top covering plate and fill the solution into the water container. Hold back powder particles which have not dissolved. Boil thoroughly until 1/3 of the solution has evaporated.

© Now switch off the machine and allow solution to react for about 10 minutes.

© Switch on the machine again and boil until the residual solution has evaporated.

© Aftenwards adjust to 1/1 programme and fil water container 3 times with water (without descaling detergent) and boil thoroughly.

© Check if the water discharge hose of the machine has been properly connected to the drain pipe on customers site.

© Operate switch (13) and fil 1,5 Itr. of water out of the boiler via fittings (17) into the 2 tr. jug. Stir in quick descaling powder (300 - 400 gr.) with a plastic spoon until the powder is completely dissolved.

© Switch off hot water unit (14).

© Remove the cap for emptying the boiler (no. 15). Open fully the draining tap behind the cap by tuming it a quarter to the left using the socket spanner provided. The boiler will now be emptied completely into the customers drain. Close the draining tap again by tuning it as far as possible to the right.

© Remove the cap of the top covering plate above the water boiler and fil in the prepared solution with the funnel.

© Switch on the hot water unit (14). After letting the machine heat up fpr approx. 5 minutes operate switch (13) and let approx. 0,5 tr. of water out of the boiler via fitings (17). Alow the solution to react for approx. 10 minutes.
