INSTALLATION
PLUMBING
Water pressure: 5 - 50 psi (min.-max.)35 - 345 kPa (min.-max.)
1. Fit a stop valve on a cold water line and attach a ¾” BSP male fitting
2. Connect the straight tail-piece of the flexible hose to the stop valve fitting. Make sure
that pre-attached sealing washer is secure.
3. Connect the right angled tail-piece of the hose to the inlet valve of the brewer (in the
base of the machine); again making sure that the pre-attached sealing washer is secure.
4. Turn on water supply and check that the fittings have sealed.
5. A hose is not a permanent connection so itis advisable to close the stop valve when not
in use for long periods (e.g. weekends/holidays)
For model 1000384Push Button Rear Delivery, there is an optional drain hose to allow urn to be
emptied into a drain or container by turning the key on the side panel. However the bunged hose
must be replaced with a suitable hose to facilitate this.
For model 1000385, the Coffee and Hot Water output is controlled via Front Push Buttons. These
operate in a “Push and Hold” mode. To drain the coffee urn a key switch is located at the front on
the unit. When operated this key switch will open the Coffee output valve and allow the coffee urn
to drain. A suitable container should be used.
ELECTRICAL
When installing the product, always observe the local regulations and standards.
Products without an electrical plug are to be connected by an authorised professional
installer.
N.B. THESE APPLIANCES MUST BE EARTHED!

1900057 REV.3 4
FIRST TIME OPERATION
1. Check that all installation procedures have been carried out.
2. Switch on the power to the unit by pressing the Power Button (See below); all the LEDs
on the control panel will flash momentarily.
3. The machine will automatically take in water. The ‘Power On’ LED will begin to flash
until water has passed safely above the elements (~ 3 minutes).
4. Heating will begin, and the ‘Power On’ LED will stop flashing and glow.
5. When the water has reached the high level and is up to temperature, the green ‘Ready
to Brew’ light illuminates. The appliance is now ready for brewing and water can be
drawn off from the hot water tap.
QUICK OPERATION INSTRUCTIONS

1900057 REV.3 5
BREWING
HOT WATEROPERATION
Approx. 5.7L of water is available as an immediate draw-off; after this no water is available until
the machines heat fill cycle has recovered. This is to ensure that any water drawn off is at the
correct temperature.
BREWING OPERATION
1. A brew can be selected any time the green ‘Ready to brew’ light is illuminated.
2. Slide out the coffee filter bowl and place a single sheet offilter paper inthe bowl.
3. Put the desired amount of ground coffee into the filter paper. Your coffee supply company
may have pack sizes to suit the brews of your Qwikbrew 2.
Depending on the coffee grind and roast, and on water quality, you may have to adjust
these quantities to obtain the optimum flavour.
4. Level off the surface of coffee by gently shaking the filter bowl.
5. Slide the coffee filter bowl into the guide rails in the brew head and push fully home.
6. Select the correct brew on the control panel by pressing the required Brew Button.
N.B. If you make a mistake press the Power Button to turn the machine off. Wait 3
seconds and turn back on again. Select the correct brew.
7. A 3L brew should take around 4-5min. A 6L brew should take around 8-10min.
8. As soon as possible after brewing –remove the filter paper with the spent grinds.
Note: allow time for all the coffee to drain from the filter bowl before removing.
SETTINGBREWWATER VOLUMES
When in volume calibration mode you are selecting the overall water flow time for each brew. The
sprayhead outputs approx 700mL/minute which is 11.66mL/second. You can select 1, 2 or all 3
brew volumes in the one calibration session, they can be selected in any order, e.g. brew 2 could
be the lowest or highest volume depending on when you press the brew 2 button. So if you want a
volume of 3.5L in brew 2 you would press 2 after 5min(=300sec), (11.66mL/sx300s=3.5L), see
table guide.
To Calibrate Volume
1. Turn the brewer on by pressing the power button.
2. Press and hold any of the brew buttons for 5+ seconds, your timer should be started the
moment you press the button down. (any brew button can be pressed to enter
calibration mode, e.g. you could press & hold brew 1 if only calibrating brew 3)
3. The power on red LED will blink to show you are in volume calibration mode, no water
will flow at this time.

1900057 REV.3 6
4. When the desired time has passed press the corresponding brew button to select this
volume for that brew.
5. When all required brews are selected turn the brewer off using the power button to save
your settings.
(To disable a brew button select a water flow time of less than 10seconds.)

NOTE- * A certain volume of Brew water will be retained in the coffee grinds and so the Coffee
volume will be less than the Brew Water volume. This will depend on the Coffee grind and weight.
Trails will be required to determine this volume. On average 1gram of coffee absorbs 2ml of water.
Verification of Volume Settings
Select a brew and measure the actual water output, if it is too low or too high a volume you can
recalibrate and extend or reduce your water flow time. e.g. if you set brew 1 to have a water flow
time of 8min 34sec you would expect to get 6L (as the flow rate is approx 700mL/min), if you got
6.1L then you will want to reduce it by 100mL.
Assuming the flow rate of 11.66mL/s, to achieve a 100mL reduction, use the following equation to
determine the time difference required:
100mL/11.66mL/s = 8.6s (round up to 9sec)
So you would enter volume calibration mode and select a new flow time of:
8min 34sec –9 sec = 8min 23sec
If you need to recalibrate any brew button follow the calibration instruction for that button. Once
you have recalibrated the required brew button press the power button to save this new setting. It
is not necessary to recalibrate the other brew buttons. Pressing the power button in calibration
mode will only save the settings which have been changed. All previously saved settings will
remain.

CLEANING
Like any cooking utensils the coffee urn of your Qwikbrew 2 must be cleaned properly and
regularly.
Marco recommends cleaning after each days brewing using a suitable urn-cleansing compound.
Marco’s own brand cleaner is available (Part Number 8000235), instructions are given on each
tub. Your Qwikbrew 2 is supplied with one large urn cleaning brush and one small sight-glass
cleaning brush –to assist thorough cleaning.
The exterior of the machines may be cleaned with a damp cloth and a light detergent. Do not use
abrasive cloths or creams, as this will spoil the finish of the machine. Do not use a water jet or
spray. Beware of accidentally operating the draw off tap when cleaning the front of the machine.
For machines with Push Button Delivery
For model 1000384Push Button Rear Delivery.
This model comes with an optional drain hose to allow the user to empty the Urn into a drain or
container by turning the key on the front panel.
However some residue can be left in the tap and dispense valve and this residue should be also
drained off prior to performing a new brew.
The key should be removed after use and stored in a safe place to remove the possibility of
accidental emptying of Urns.

1900057 REV.3 8
DESCALING
The only regular maintenance required is occasional de-scaling.
In common with all coffee brewer manufacturers, service calls resulting from limescale are not
covered by warranty. Fitting a scale reducer is recommended, especially in hard water areas.
Marco can advise on suitable water treatment by contacting [e-mail]
A service agent should descale the machine regularly. Marco suggests that the machine be
descaled every 3 months if the unit is in a hard water area. In soft water environments every 6
months should suffice.
TROUBLESHOOTING
The Marco Qwikbrew 2 uses an electronic diagnostic system to help determine faults. If an error is
detected a sequence of flashes is displayed through the POWER light.
