Introduction, Safety Information & Equipment Specifications
Introduction
This manual guides you through maintaining and servicing the equipment with step-by-step
instructions. We understand that this is a fairly large machine and the working space around it and
behind it may be limited. For this reason, we designed this equipment so that all servicing can be
done from the front of the machine. While there may be some cases where servicing will be easier
from the back, this same servicing is also possible from the front if no space is available.
Disconnect the machine service cord from the wall outlet and disconnect the
water supply prior to servicing.
Safety Symbols
Your safety is extremely important to us. To avoid personal injury or damage to the equipment
and its surrounding areas, it is imperative that you read and understand the safety information
outlined in this section before proceeding with the installation and operation of this equipment.
The following symbols are used throughout this publication:
Indicates an electrical shock hazard.
Indicates a potential safety risk, or a risk of damage to equipment and/or its
surroundings.
Indicates important information that must be understood before proceeding.
Indicates an important note or useful tip.

Care and Maintenance
To keep the Eccellenza Momentum™ 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.
Failure to perform the required care and maintenance will result in poor
beverage quality and will lead to equipment malfunctions. It may also void
any remaining warranty on the equipment and its components.
Daily Care
►Empty the Cup Stand –empty the contents of the cup stand and rinse the stand
and grill under clean running water.
►Empty the Waste Bin –empty the contents of the waste bin.
►Refill the Coffee Dispensers and Powder Dispensers –top off the coffee and
powder dispensers. Do not pack the products into the dispensers!
►Wipe Exterior and Countertop –using a clean towel, wipe any coffee grounds and
spills from the exterior of the machine and the countertop.
Every 1-2 Weeks
►Clean the whipper components - for detailed information about disassembling and
cleaning the whipper components, go to page 44.
►Inspect Water Hoses and Tubing - inspect all plumbing connections, water hoses,
tubing, clamps, fittings and water related components (valves, water tank, etc.) for
signs of wear or damage. Replace them, if required.
Every 15,000 Cycles or 12 Months
►Clean the brewer components. For detailed information about disassembling the
brewer, go to page 25.
►Clean the whipper hoses - remove all three whipper outlet hoses and thoroughly
clean the exterior and the interior of each of the hoses. A plastic bristled brush (VKI
P/N - 202477-001) must be used to clean the interior of the hoses.
►Replace whipper seals -replace the rubber seals on all three whipper bases.

Section 2 - Maintenance
Service Manual
VKI Publication #202378-001

►Replace Brewer Seals and Gaskets - there are several seals and gaskets located
throughout the brewer assembly that need to be replaced every 12 months or
15,000 cycles. The brewer 'Yearly Maintenance Kit' (p/n - 202341-003) contains
everything required.
►Inspect Electrical Wiring and Components - inspect all of the equipment wiring,
terminals, connectors and electrical components (valves, motors, relays, element, etc.) for
signs of wear, damage or overheating at connection points. Replace them, if required.
Every 3 Years - Technician
►Replace the following: heater element, thermal cut-off switch and external relay,
all seals and gaskets and o-rings.
Miscellaneous
►Run the Brewer Rinse and/or Mixers Rinse Cycles when prompted by the machine
(a message appears on the touch screen).
►Run the Brewer Cleaning cycle using the Urnex TABZ Z61 cleaning tablets –see the
Momentum™ Operation Manual (VKI Publication #202377-001) for more details.
►Run the Grinder Cleaning cycle using the Urnex SuperGrindz A01 cleaning pellets –
see the Momentum™ Operation Manual (VKI Publication #202377-001) for more
details.
►Verify Water Tank Components - dependent on the local water condition - inspect,
clean or replace components, as required.
►Clean the Side Exhaust Fan -over time, dust will accumulate on the exhaust fan on
the right side wall and it must be cleaned to maintain the fan’s performance.
►Cleaning the Coffee Dispenser - empty, remove, and clean the coffee dispenser
with warm water and dish soap. Thoroughly dry the dispenser before re-installing
it. For detailed information about removing the coffee dispenser, go to page 37.
►Cleaning the Powder Dispensers - empty, remove, and clean the powder
dispensers with warm water and dish soap. Thoroughly dry the dispensers before
re-installing them. For detailed information about removing the powder
dispensers, go to page 39.
►Inspect the grinder –to prevent the grinder from jamming, re-adjust the grinder
heads if the coffee grounds are too fine, and keep the grinder chute clean –page 38.
Failure to perform the required care and maintenance will result in poor
beverage quality and will lead to equipment malfunctions. It may also void
any remaining warranty on the equipment and its components.

Sanitizing Procedure
Eccellenza Momentum™ components that come into direct contact with the beverage
ingredients must also be sanitized when necessary to conform to the FDA Food Code. This
process must be performed as required by local health authorities and health regulations.
The following components require a thorough cleaning and sanitization:
•Brewer
•Coffee dispenser
•Powder dispensers (3)
•Whipper steam traps (3)
•Whipper chambers/mixing bowls (3)
•Whipper impellers (3)
•Whipper elbows and hoses
•Dispensing spouts (coffee and powders)
•Cup Stand & Grill
1. Prepare a sanitizing bath consisting of solution of clean water and Diversey/SC Johnson
J-512 sanitizer (2ml of J-512 sanitizer per liter of water). Fill a spray bottle with this
same solution –it will be used to sanitize the brewer and dispensers.
When ready for use, the end-use concentration of all quaternary sanitizers in
the solution is not to exceed 200ppm of active quaternary compound.
Consult the product label for more details.
2. Remove the filter screen from the brewer.
3. Wash the other components (including the brewer filter screen) with water and dish
detergent. To clean the brewer, wash the inside of the cylinder as well as the brewer
piston rod.
4. Rinse the components thoroughly under clean running water.
5. Set the brewer, coffee dispenser and three powder dispensers aside, for the moment.
6. Place the remaining components into the sanitizing bath for about 5 minutes.
7. While the components soak, use the spray bottle and spray the sanitizing solution to
the inside and outside of the brewer cylinder, and to the piston rod. These parts must
be completely soaked by the solution.
8. Spray the sanitizing solution to the inside and outside of the coffee and powder
dispensers and allow the solution to dry naturally - do not wipe away the solution.
9. Rinse the components that were in the sanitizing bath under clean running water.
10. Rinse the inside and outside of the brewer thoroughly under clean running water.
11. Set all of the components aside and allow them to dry completely before using them.
12. Lightly spray sanitizing solution to the exterior of the machine, the interior walls, the
interior of the front door, the whipper bases, and to the counter-top on which the
machine is installed. Do not wipe away the solution –let it dry naturally.

The following symbol is used to identify a "touch" location on the machine's
touch screen.
Clearing Error and Reminder Messages
Should an error or reminder message be triggered, the error or message is displayed at the
lower left of the screen. In the example below, the message reads "Please reinsert waste bin".
However, in our example, there are three messages present, as indicated by the number "3" in
the upper right corner of the screen. Messages are stacked in the order in which they occur.
In this case, the waste bin has been removed and its presence is not detected. The waste bin
must be replaced to clear this message.
In a case where multiple messages are present, after clearing the first message, any
subsequent messages are displayed (one at a time) until they are all cleared.
If a "Call for Service" error is displayed, you need to go to the "System
Status" menu to get more details about the error.
