Introduction
The information held within this section has been compiled by the manufacturer to provide
recommended guidelines to operator personnel and is intended to be used in conjunction with any
existing operating procedures your company uses.
Hygiene
In accordance with the food hygiene (Amendment) regulations 1990 (SI 1990 No. 1431) and in
compliance with the local public health authority requirements, it is the responsibility of the machine
Operator to keep this machine maintained in a clean condition to ensure the highest standards of
hygiene needed to prevent the formation of bacteria. A regular, systematic method of cleaning will
help achieve this condition.
A high standard of personal hygiene is essential for a vending machine Operator.

fingernails must be washed thoroughly before work commences, particularly after each visit to the
toilet area. Jewellery should be kept to a minimum and preferably removed during any cleaning
operations.
An operative who is suffering from cuts, sores or any form of illness must inform their immediate
superior at once and must not come into contact with this vending machine, ingredient products,
cups or any other machine related items. The operative must not resume work until authorised to
do so by their immediate superior.
Important safeguards
1. Read these instructions before attempting to clean or refill the machine.
2. Do not attempt to operate the machine if any part is damaged. If either damage or a fault is
suspected contact your nearest available Service Engineer for assistance.
3. Never immerse the machine in water or any other liquid.
4. Never clean the machine with a water jet.
5. Always switch off and disconnect the machine from the mains electricity supply before
cleaning and servicing.

Ingredient canisters – removal, filling and cleaning.
1. When removing canisters always position the chutes in the upright position this will prevent
any spillages.
2. If your Sigma Touch is fitted with ventilated chutes refit horizontally.
Note! Repetitive turning of the chutes over a period of time can cause the auger fittings to
become loose. Turning the chutes manually also makes a mess.
3. Remove the instant ingredient canisters by tilting them backwards to lift the front locating peg
from its hole. Pull the canister towards you, whilst lifting the front of the canister by 10mm.
The canister(s) can now be removed and placed onto a clean, dry surface.
4. Shake the instant canisters to loosen any compacted
ingredient.
5. Place the canisters on a stable surface and fill with dry fresh
ingredients to the required level, replacing lid.
6. Do not fill canisters whilst in any machine this will cause the
following:
Malfunctions
Blockages
Explosions
Dispense pipes will be blocked with beans etc.
Service callouts
DON’T
1. Overfill canisters on low volume machines.
2. Leave bags of product on top of canisters.
3. Leave bags of product or syrup open in the vending machine; this will attract small insects.
4. Overfill the machine with spare ingredient or cups.
5. Leave any debris, product wrappers etc inside the machine.
6. Force components into position.
7. Stand on any lower part of the machine to access the top.

Operator level door open software menu tabs and their meanings
To access the door open Operator menus simply open the machine door.
The menu tabs on the screen allow you to access files such as the audit. Press on the menu tab
and the information will be displayed on the screen.
Display audit
Audit mode provides the ability to view the overall total drink volume and values dispensed.
Telemetry
In the near future all audit information will be accessible through telemetry and data analysis.
How will telemetry work?
Telemetry will allow businesses to communicate sales and inventory data to a route vehicle or to a
head office. This data could be used for a variety of purposes, such as eliminating the need for
drivers to make a first trip to see which items needed to be restocked before delivering the
ingredient / products.
