G 7728 23 M.-Nr. 3869752/04 -GB-Operation COMMISSIONING Read the enclosed “First commissioning” lea- flet carefully when the machine is commis- sioned for the first time. This machine should only be commissioned by the Miele Service Department or an auth- orised Miele Dealer. When the machine is first commissioned the reactivate softener switch on the facia panel must by set to a value which represents the local water hardness level (see page 26). Only use rinse aids specifically designed for use in commercial dishwashers in this ma- chine and dispense according to the manufac- turer’s recommendations. See relevant Technical Instructions for notes on connection and dispensing. When changing rinse aid brands the dispen- ser system should first be flushed through with clean water and the dispenser amount re- set accordingly. The rinse aid dispenser is situated in the base of the dishwasher. The on site suction hose should be shorte- ned to the shortest length possible and the siphon re-fitted. Insert the siphon back into the rinse-aid container. Open the on-site stopcock. Close the hood. Set the selector switch to “Ready to wash”. The wash cabinet automatically fills with water (see separate instruction sheet, “Commissioning for the first time"). When the “operating temperature has been reached” and the “in operation” indicator lights have lit up, a wash programme pro- ceeds. When the “Programme in operation” indicator light goes out: G 7728 The hood opens automatically. G 7726 / G 7727 Open the hood manually. Adding powder detergent Do not use detergent intended for washing up by hand. Only use detergent specially formu- lated for use in a dishwasher. Recommended quantity: At least 2 grammes per litre of water, i.e. approx 100 grammes for a full wash tank. After every 10 cycles a further 50 grammes should be added. Follow the detergent manufacturer’s instruc- tions on dosage. Wearing protective gloves add detergent manually to the wash tank and mix with water in the tank immediately, by closing the hood and running a programme so that it is thoroughly mixed in. é é M.-Nr. 3869752/04 -GB- 24Operation Drawing up and adding Rinse aid Set the selector switch to the “Manual dis- pensing”.

l ● K ● 27 M.-Nr. 3869752/04 -GB-Note Cleaning and Maintenance Intervals between washes While the machine is not in use the emission of steam can be reduced by turning the selector switch to “manual operation” and closing the hood. When the machine is to be used again the hood should be opened (with the G 7728 press the “Open Hood” button in) and select a programme. If wash results are unsatisfactory, change the water in the wash tank. (See “Cleaning” for how to drain). Each time the wash tank water is changed, add detergent and rinse aid. (See daily “Com- missioning” for adding detergent and rinse aid. If possible, glasses should only be washed after the wash tank water has been changed. This gives better wash results. The rinse aid container should never be allowed to get empty. Refill or replace it in good time. CLEANING Do not use a hose or high pressure spray to clean the dishwasher or its immediate sur- roundings. The wash cabinet should be cleaned when necessary or after a number of programme cycles, using the “Manual rinse programme. Remove the basket runners (KR), wide surface area filters (F) and standpipe (ST). Set the selector switch to the “manual operation” position. Close the hood. Set the selector switch to “Manual rinse” and allow the dishwasher to wash for ap- prox. 10 seconds to clean the wash cabinet through. G 7728: Press the “Open hood” button. G 7726 / 7727: Open the hood manually. Replace the standpipe (ST), wide surface area filters (F) and basket runners (KR).

M.-Nr. 3869752/04 -GB- 28Cleaning and Maintenance Depending on the degree of soiling the follow- ing should be cleaned from time to time: Rinse arms (SR), spray arms (SA), - after undoing the securing nut (B), remove the rinse and spray arms. Check for particles of soiling when necessary and clean. The mullion (SG) and Filter (S). - be careful not to allow large particles of food to make their way into the circulation pump opening. Caution Protect the bearing surface (L) of the rinse arm from being damaged. Do not refit rinse arms with damaged bearings. The filter situated between the water inlet and the connecting hose (inlet filter) should be cleaned from time to time. This should be carried out by the Miele Service Department. REACTIVATE (Only for machines with a water softener) A reactivate water softener programme should be carried out as soon as the “Reactivate” indicator light comes on. If this is not immediately possible due to operating conditions and further batches have been washed, then the reactivate pro- gramme must be run twice in succession. Remove the basket runners, large surface area filter and stand pipe in order to drain the machine. Unscrew the cap (VK) on the socket. Fill the salt container supplied with 2 kg of reactivation salt. Only use special reactivation salt ie. with a grain size of 1-4 mm. SR SA

29 M.-Nr. 3869752/04 -GB-Cleaning and Maintenance Important Only use special coarse grained dishwasher salt for reactivation, as any other salts may contain insoluble impurities or additives which can impair the functioning of the softener. If the only reactivation salt available is fine grain, please consult your Miele service repre- sentative. Reactivation salt with granules larger than 4 mm cannot be used. Never fill the salt reservoir with dish- washer cleaning agent. This can damage the water softener and cause irritation and in- jury. Screw the salt container on to the socket. Set the selector switch to the “Reactivate” position. Close the hood. Reactivation takes about 24 minutes. The reactivation process is complete when this period has elapsed or when no more water inlet noises are audible. G 7728 The hood opens automatically. G 7726 / 7727 Open the hood manually. Set the selector switch to “0". After reactivation has taken place the reac- tivate softener switch should be turned in a clockwise direction using a coin until a resistance is felt. The “Reactivate” indica- tor light goes out. Important: The water pressure (flow pressure at the take off point) must be at least 2.5 bar. If the flow pressure is below 2.5 bar, or if it fluctuates, the water softener will not be set properly. There may be salt residues in the base of the salt container after reactivation has taken place. To use up the salt remains and to wash out the water softener the “Reactivation” programme will need to be run again. Note: The salt container should be opened gradually until water escapes thus allowing it to depressurize. Put the cap back on the socket and immediately remove any salt residues using the manual rinse programme. Rinse out the salt container and the insert. Refit the standpipe, large surface area filter and the basket runners. Fill the tank, add detergent and rinse aid. - See daily commissioning. - Maintenance of the dispenser system The dispensing pump hoses are subject to wear and tear, and should be checked at regular intervals, and when necessary re- placed by your Miele dealer or the Miele Ser- vice dept. This should be done at least yearly, or after 3000 programmes at the latest.

WARNING: THIS APPLIANCE MUST BE

EARTHED Connect the machine to the electrical supply making sure that it is connected to a correctly installed earthing system. The machine must be included in the overall bonding calcula- tions. Consult the data plate and wiring diag- ram. For extra safety it is advisable to install a re- sidual current device with a trip current of 30 mA (in accordance with DIN VDE 0664, VDE 0100, Section 739). When switched off there must be an all-pole contact gap in the isolator switch (including switch, fuses and relays according to VDE 0660). Nominal rated load and fuse rating are given on the data plate. Ensure that these are com- patible with the electricity supply. The heater is set to 9 kW ex works (inter- locked = boiler switched on in precedence to tank heating). - reduced plate throughput - The heater rating can be increased to 13.5 kW (unlocked = boiler and tank heating would then operate simultaneously). The desired heater rating should be set before final installation of the machine. Follow the wiring diagram (located behind the lower service panel). Mark the set heater and fuse ratings perma- nently on the data plate with a “
