  • Page 11 The washware must be suitable for dishwashing machines. If there is any doubt, a consultation (size, version, basic suitability for dishwashing machine, etc) can be carried out with MEIKO to confirm suitability (info@meiko-global.com). The following applications are expressly not intended: •...
  • Page 12 • Only appropriately qualified and authorised personnel operate, maintain and repair the dishwashing machine. • No one sits or stands on the open door. • Staff are regularly trained in all questions relating to occupational safety and environmental protection and are familiar with the operating instructions and, in particular, the safety information that they contain.
  • Page 13 • Do not confuse detergent and rinse aid. • Ensure that the suction connections for the dishwashing machine are correctly connected to the canisters. Information on the use of descaling agents Residue from descaling agents can cause damage to the plastic components and sealing materials in the machine.
  • Page 14 Product description Functional description The UPster U 500 M2 is a commercial glass and dishwasher with a square rack. The dishwasher has one wash and one final rinse cycle. A temperature regulator maintains the set wash temperature of between 58-60 °C. A rotary pump circulates the water from the wash tank into the wash nozzles.

  • Page 16 GiO MODULE The module works according to the principle of reverse osmosis. Drinking water is pressed by a pump through a semi-permeable membrane. The membrane lets only water molecules through. The hardness components and salts (lime scale, etc.) con- tained in the water are held back. The clean water (permeate) is brought to the dish- washing machine;...
  • Page 17 The correct dosage is achieved when the water drips evenly from the washware and depends on the available water quality on-site. This setting is made during commis- sioning by an service technician authorised by MEIKO or the chemical supplier. Change dosing quantity, see chapter “Dosing system level” on page 46.
  • Page 18 The water softener is preset to 30° dH at the factory. This value is adapted to the actual water hardness during commissioning. Additionally, this parameter has to be changed by a service technician (MEIKO-authorised) if the water hardness changes. 9760465...
  • Page 19 Make sure that the dishes and glassware used are suitable for the high stress placed on them. MEIKO offers two types of machine with thermal disinfection for institutions with ad- ditional hygiene requirements. Both versions have greater heating performance in the wash tank than standard machines.
  • Page 20 The display shows the current A value. Thermolabel control In a way which is similar to A control, machines with Thermolabel control have a disinfection process which uses moist heat. The dishwasher heats the rinse water to a higher temperature in order to eliminate germs. The efficacy of the disinfection can be tested using a measurement strip, the Thermolabel.
