     Slide out the coffee filter basket and place a single sheet of filter paper inside Put the correct amount of ground coffee into the filter paper. Your coffee supply company may have pack sizes to suit the brews of your new Qwikbrew 2; if not, as an approximate guide for your first brews: Try about: 110g-130g (4-4½oz) for a 5 pint brew (2.85 litres)

  • Page 11: Lock Function

    This is a particularly useful function in a self-service environment. Fig.6 – Display 7. HYGIENE Like any cooking utensils, the coffee-holding urn of your Qwikbrew 2 must be cleaned properly, regularly. MARCO recommend cleaning after each day's brewing using a proprietary urn- cleansing compound.

  • Page 12: Technical Data

    Maintenance should be carried out by Marco approved technicians only. Access to internal components: The Qwikbrew 2 has been designed with ease of service in mind. All the components (PCB’s, inlet solenoid, probes, pump and element) are accessible from the front of the machine.

  • Page 19: Probes

    Probes: As mentioned earlier, there are 3 probes (low level, high level and brew level) on the Qwikbrew 2, the positions of which are shown in figure 2. Figures 13 and 14 show how the probes are removed. Note: Tank does not have to be drained to remove any probes.

  • Page 20: Element

    Since the European standard voltage is 230V, we are in the process of changing our elements to suit this. Figure 17 shows the element to be used on new batches of the Qwikbrew 2. This shape of element has a great advantage.

  • Page 21: De-Scaling The Tank

    De-scaling the tank: Follow instructions for removing the element. The tank can now be cleaned through the clean out door (see figure 23). Fig.18 Fig.19 Fig.20 Fig.21 Fig.22 Fig.23 Service Manual 1000379 Qwikbrew 2 01-10-12Page 21 of 37...

  • Page 23 The flow can be adjusted by closing the hose clip. There are no restrictors of the type found on previous Marco brewers. The flow rate is controlled by pipe work and in some cases hose clips. The larger bores in the hoses should prevent failures due to scale blockages.
