HACCP schedule
Chapter 6 HACCP schedule
You are required by law to ensure that your customers are not subject to any health risks as a consequence of consumption of food items you serve.
A HACCP schedule (Hazard Analysis Critical Control Points) for risk identification and assessment is required. You should carry out a risk analysis on your premises. The aim of the analysis is to recognize and pre-empt food hygiene hazard points. For this purpose, monitoring and, where necessary, test procedures must be established and implemented.
With correct installation, care, maintenance, and cleaning,
WMF coffee machines meet the requirements described above. If care of the coffee machines is not carried out properly, dispensing milk beverages will constitute a food hygiene hazard point.
Please observe the following points in order to comply with the HACCP Schedule:
Sanitize the milk system daily
• Follow the cleaning instructions for the milk system contained in the cleaning instructions. This will ensure that your system contains a minimum of bacteria at commencement of operation.
“Food Hygiene Ordinance from
05.08.1997”
Use our HACCP schedule for monitoring of regular cleaning.
You can call up the logs of the most recent cleaning operations via Information pad .
Always commence operation with a freshly opened cooled milk pack
• Original packaged UHT milk is usually free from harmful bacteria. Always open a new cooled pack at commencement of operation.
• Ensure absolute cleanliness when opening the milk pack.
Germs can be introduced from dirty hands or tools when opening.
Recommendation: only use UHT milk with a 1.5 % fat content.
User Manual WMF bistro!
47
HACCP schedule
Keep milk cool
• Always have a new cooled milk pack handy.
• If a cooled freshly opened pack is used within a period not exceeding 3 hours, refrigeration during use is not necessary.
• If little milk is being used, cooled milk must be placed in the refrigerator again during operation.
At commencement of operation milk should be at approx. 6 - 8 °C.
Depending on the setting, one litre of milk is suffi cient for approx. 20 cappuccinos.
WMF offers a range of refrigeration options
(e.g., WMF countertop coolers or WMF milk coolers).
48
HACCP schedule
Use only cooled UHT milk, to prevent health risks due to bacteria.
For Choc, use only products that have not exceeded their expiration date.

Installation clearances
Installation dimensions of the water filter
The unit must be placed on a level, flat, and sturdy surface.
The unit is not intended to be located on a surface that is sprayed or cleaned with a water hose, steam jets, steam cleaner, or similar devices.
For operating, service and safety reasons the machine should be installed with a clearance of not less than 50 mm at the back and sides from the building or non-WMF components. A clear height of 1,100 mm from the top of the supporting surface should be ensured. The height of the installation surface above the floor is at least 850 mm. If the machine connections are to be run downwards through the counter, please make space for the lines, which can reduce the usable space below the machine.
See the User Manual for the water filter.
These specifications for the electrical connection and the standards quoted apply for connecting the machine in EU countries. It may be necessary to also observe additional country-specific regulations.
Outside the EU countries acceptance of the standards quoted is to be checked by the legal entity or natural person who wishes to use the machine.
The local power supply must be constructed according to IEC 364. To improve safety, the coffee machine should be fitted with an FI 30 mA earth leakage current circuit breaker complying with EN 61008. Near the machine or about
30 cm below the counter top there should be a shockproof socket as a single-phase connection installed locally on the rear or side wall of the counter substructure or a country-specific single-phase socket and, in the case of a 3-phase connection, a 5-pin CEE / CEKON-socket according to EN 60309 or a country-specific multi-pin socket. The mains switch and plug top are part of the customer‘s on-site installation. The mains cable must not come into contact with hot surfaces. If the mains cable for this device is damaged then it must be replaced by our service personnel or a similarly qualified person, in order to prevent hazards. If the coffee machine is permanently connected to the mains then an all-pole disconnecting separator (mains switch) according to EN 60947 with a minimum 3 mm contact gap must be installed. A separator switch is recommended for a flexible connection. The machine may not be fitted with a fixed permanent mains connection if installed on a transporting trolley (a mobile station).
In order to avoid possible faults from arising on our shielded data lines due to potential equalization currents between the devices, an additional potential equalization unit should be planned for devices connected to the vending system. (See EN 60309)
