3.7. MAINTENANCE:
Marco machines have been designed to give many years of trouble free service. Marco Beverage Systems
design, manufacture and test to ISO9001:2000 standard. The only regular maintenance required is occasional
de-scaling.
In common with all water boiler manufacturers, service calls resulting from limescale are not covered by
warranty. Fitting a scale reducer is recommended, especially in hard water areas. This can reduce the build-
up of scale but may not stop it altogether. A service agent should descale the machine regularly. The
frequency that descaling is required depends on the local water supply; hard water areas need more attention.
Marco suggest 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.
3.8. CLEANING:
Like any cooking utensils the coffee urns of your Qwikbrew 2 Twin must be cleaned properly and regularly.
Marco recommend cleaning after each days brewing using a proprietary urn-cleansing compound.
Marco Urn Cleanser (Marco Part number 8000240) is available in 800g tubs. Instructions are given on each
tub. Your Qwikbrew 2 Twin is supplied with one large urn cleaning brush and one small sight-glass cleaning
brush –to ensure thorough cleaning. In order to clean the sightglass, unscrew the small plugs on the top of
the sightglass. The sightglass is fragile, so be careful while cleaning.
The exterior of these 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 taps when cleaning the front of the machine.
3.9. SAFETY:
This appliance must be earthed.

Risk of scalding. Beware of accidentally operating the water drawoff tap especially when cleaning the
front of the boiler. ALL users of this machine should be trained and should be aware that the machine
