3.2. OPERATION:
The Marco Qwikbrew 2 Twin uses the ‘Continous fill cycle’ as standard.
Continuous Fill Mode:
Water will be taken in until the machine is full. The heating begins when the quantity of water is at a
safe level above the elements and stops when the machine is full and up to temperature.
Once the water is up to temperature, the green ‘Ready to Brew’ lights illuminate (approximately 50
minutes after start up). A brew can be selected at this point.
The ‘Continuous fill mode’ essentially keeps the machine full of water, regardless of temperature. In
this mode the machine will never run out of water, but misuse (e.g. filling buckets for cleaning) can
allow cold water to be served. Using hot water at a faster rate than the machine can recover will
result in a temperature drop in the beverage. Recovery rate is approximately 1.5 pints/min.
Heat-fill mode (Optional):
This mode of operation is available as an option, but a service agent is required to make this change.
Water will be taken in until it is a safe level above the elements. At this point the water stops and
heating begins. Once this quantity of water is up to temperature, another small quantity of cold water
is taken in while the heating continues. This heat fill cycle maintains the correct temperature in the
tank.
When the machine has enough water to brew coffee, the green ‘Ready to Brew’ lights illuminate (after
approximately 40 minutes). A brew can be selected at this point, but the machine is NOT full yet and
will continue to fill. After approximately 50 minutes the heaters will shut off. The machine is now full
and up to temperature.
Tea and coffee is at the optimum temperature when operating under the heat-fill mode.
3.3. BREWING COFFEE:
Slide out the coffee filter bowl and place a single sheet of filter paper in the bowl.
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 Maxibrew 2 Twin; if not, as an approximate guide for your
first brews:
110g-120g (4-4½oz) for a Half Brew (5 pints [2.85 litres])
220g-240g (8-8½oz) for a Full Brew (10 pints [5.7 litres])
Depending on the coffee grind and roast, and on water quality, you may have to adjust these
quantities to obtain the optimum flavour.
Level off the surface of coffee by gently shaking the filter bowl. Slide the coffee filter bowl into the
guide rails in the brew head and push fully home.
Select the correct brew on the relevant control panel (e.g. left control panel if the left urn being used)
by pressing either the Half Brew switch for a 5 pint brew or the Full Brew switch for a 10 pint brew.
Press the switch until the amber light illuminates. If you make a mistake press the Power switch to
turn the machine off. Wait 3 seconds and turn back on again. Select the correct brew.
A half brew should take around 4 min - 4 min 45 secs. A full brew should take around 8 mins - 9
mins 30 secs. These depend on the set up of the machine (factory).
Note: A service agent can set the machine up so that different brew times are available in each urn, for
different strengths/types of coffee. Half-brew times can be varied from 3 mins +- 10 seconds to 7 mins +-
10 seconds and Full-brew times can be varied from 6 mins +- 10 seconds to 14 mins +- 10 seconds.
