Rinse Cycles
Brewer Rinse Cycle
1. Add VKI approved brewer cleaner to the brew chamber.
2. Press the "RINSE CYCLE" button on the control panel inside the front door.
To exit the rinse cycle if it was pressed accidentally, press the “PREVIOUS”
button on the front display.
3. Select the type of rinse cycle required. For a brewer rinse, press the "Coffee
Rinse" button on the front selection panel to begin the cycle.
To cancel the rinse cycle if it was pressed accidentally, switch OFF the
machine using the main power switch at the rear.
a) The piston will move to the top of the cylinder, water will pour in, and
the brewer will pause for about 5 minutes. During this time, the cleaner
breaks down all the oils and stains that have accumulated in the brewer.
b) After the 5 minutes have elapsed, the brewer will cycle, dumping the
cleaner into the waste container in the process. The brewer will then
automatically cycle water seven consecutive times to rinse the cleaner
from the brewer. After the rinse cycle is completed, the brewer will
stop and the coffee maker will automatically exit the rinse mode.
c) After the rinse cycle is complete, brew a few cups of coffee to re-
lubricate the brewer.
WARNING: Make sure the waste container is under the brewer spout
to catch the water coming from the brewer (throughout the complete
rinse cycle).

2. Select the type of rinse cycle required. For a quick brewer rinse, press the
"Quick Cof. Rinse" button on the front selection panel to begin the cycle.

preparing a coffee beverage, however, only hot water will be
dispensed into the brewer (without coffee grounds). Repeat this
process, if necessary.

Maintenance
To keep the Eccellenza Café running efficiently and at peak performance, the
following maintenance procedures must be performed at their specified intervals. It
is recommended that equipment maintenance be scheduled at a time that would be
the least disruptive to your customers. Whenever possible, replace the components
requiring maintenance with new or refurbished ones, and then refurbish the older
components at your shop.
Daily
►Empty the Drip Tray – empty the contents of the drip tray and rinse the
tray and grill under clean running water.
►Empty the Waste Bin – empty the contents of the waste bin.
►Empty the Pan Tray – empty the pan tray and rinse the tray under clean
running water.
►Refill the Coffee Hoppers, Powder Hoppers and Flavoring Bottles –
top off the coffee and powder hoppers, as well as the flavoring bottles and
reset the product counters.
►Perform a Whipper Rinse Cycle – this should be done immediately after
refilling the powder hoppers to flush any product that may have fallen into
the whipper.
►Wipe Exterior and Countertop – using the clean towel, wipe any coffee
grounds and spills from the exterior of the machine and the countertop.
Weekly
►Wipe Interior Walls and Door - using the clean towel, wipe any coffee
grounds and spills from the interior of the machine and the front door.
►Perform a Brewer Quick Rinse Cycle – for the weekly Brewer Quick
Rinse cycle, it is not necessary to use any brewer cleaner. Simply flushing
the system with the hot water will help to keep it clean.
►Clean the Brew Chamber – the brew chamber should be removed and
thoroughly rinsed under warm running water.
►Clean the Grinder Spout – coffee grounds will accumulate in the grinder
spout opening due to static electricity and moisture from the brewer. The
grounds need to be removed or the grinder may jam. With the brew
chamber removed, use a plastic stir stick to delicately remove any coffee
accumulation from around the inner edge of the grinder spout.
CAUTION: Never use ammonia based cleaners on machine
surfaces as they will become discolored and/or damaged
permanently. Use mild cleaning products, such as dish soap.

Eccellenza Café – Service Manual
12 August 5, 2013
Monthly
►Perform a Brewer Rinse Cycle – the full Brewer Rinse cycle requires the
use of brewer cleaner to remove oils and stains from the brewer.
►Clean the Brewer Filter Screen – to minimize servicing time, replace
the filter screen with one that has already been cleaned, then clean the
stained filter screen at the shop and use it the next time a filter screen
replacement is required.
►Clean the Whipper System – disassemble the whipper system and clean
the components with hot water.
•NOTE: When re-assembling the whipper components, always add some
Lubrifilm lubricant to the base of the shaft in the area where the whipper
base gasket is located.
►Clean Hoses and Spouts – clean the exterior of all the product hoses
and spouts with a wet towel.
►Thoroughly Clean the Interior – clean the interior walls, base and
components with a clean wet towel.
Every 6-12 Months
►Clean the Coffee and Powder Hoppers– the hoppers should be
emptied of product and given a thorough cleaning to remove stains and
oils that may have accumulated inside them.
►Clean and/or Adjust the Grinder – remove the grinder cover and clean
the area around the grinding heads. Should the coffee being ground look
too coarse, the grinder may require a re-adjustment.
►Delime the Water Tank -to minimize servicing time, replace the water
tank with a tank that has already been delimed, then clean the removed
tank at the shop and use it the next time a tank replacement is required.
►Clean the Outlet Valves - to minimize servicing time, replace the outlet
valves with valves that have already been cleaned, then clean the removed
valves at the shop and use them the next time a valve replacement is
required.
►Replace the Water Filter – the water filter should be replaced at least
once a year, or when the water flow rate through the filter has decreased.
This is an indication that the filter is starting to clog.

interior of the front door, the whipper blade and base, and to the counter-top.
Do not wipe away the solution – let it dry naturally.
6. After their 5 minute soak, remove the components from the leak-proof
container and rinse them with clean warm water.
7. Re-install all of the components back into the machine.
NOTE: When ready for use, the end-use concentration of all quaternary
chemicals in the solution is not to exceed 200ppm of
active quaternary
compound.

Should the flavoring system ever require sanitization, the following procedure must
be performed. Please note that safety goggles and latex gloves should be worn at all
times throughout this procedure.
1. Remove the disposable flavor bottles from their supports.
2. Remove the silicone bottle caps from the bottles and completely immerse
them in sanitizing solution (2ml of S.C. Johnson J-512 Sanitizer per one liter
of water) for approximately 5 minutes.

re-used for any purpose!
4. Fill a spray bottle with a solution of J-512 Sanitizer and clean water (2ml of
sanitizer per liter of water) and thoroughly spray the outside of the flavor
tubes (bottle side) with the sanitizing solution. Do not wipe the solution.
5. Fill three empty and clean flavor bottles (minimum 250 ml) with S.C. Johnson
J-512 Sanitizer (2ml of S.C. Johnson J-512 Sanitizer per one liter of water).

11. Once rinsed, fill the three bottles with potable water. Place the bottles (again
without caps) onto their supports and insert the respective tubing into each
of the bottles.
12. Press the “START” button on the front selection panel to activate the
automated rinsing procedure. All three pumps will cycle continuously until all
of the clean water in the bottles has run through the flavor system, rinsing any
remaining sanitizing solution in the process.
NOTE: When ready for use, the end-use concentration of all quaternary
chemicals in the solution is not to exceed 200ppm of active quaternary
compound.
NOTE: If three empty flavor bottles are not available, you can use a clean
one liter container (with 2ml of sanitizer per one liter of clean water). Insert
all three inlet flavor tubes into this one container of sanitizing solution.
