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 preempt 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 instruction. This will ensure
that your system contains a minimum of bacteria at
commencement of operation.
You can call up the logs of the most recent cleaning
operations via information pad .
Always commence operation with a freshly opened
prerefrigerated milk pack
• Original packaged UHT milk is usually free from harmful
bacteria. Always open a new pre-refrigerated pack at
commencement of operation.
Ensure absolute cleanliness on opening the milk pack. •
Germs can be introduced from dirty hands or tools
when opening.
“Food Hygiene Ordinance from
05 .08.19 97“
Use our
HACCP schedule for monitoring of
regular cleaning.
Recommendation:
Only use UHT milk with a 1.5 % fat
content.

replaced in the refrigerator again during operation.
Recommendation for Choc and Topping (optional)
Regularly clean the product hopper. See the instructions in
the Customer Care chapter.
See chocolate / Topping manufacturer‘s instructions.
At commencement of operation
milk should be at approx. 6 - 8 °C.
Depending on the setting, one litre

Maintenance
Chapter 7 Maintenance
Please observe that this is a professional industrial coffee
machine which needs regular maintenance and descaling.
Timing of descaling is calculated by the machine and
depends on the degree of hardness of the local mains
water and whether or not a filter is fitted.
The maintenance schedule is based on the degree of use
of the machine and is shown on the display. The coffee
machine may continue to be operated after the message
but Customer Care or contract maintenance should be
carried out promptly to ensure correct functioning and so
as to avoid any consequent damage.
7.1 Coffee machine maintenance
The following care or maintenance stages are provided:
Descaling, may be undertaken by the user / operator. •
• Customer Check-up every 7,500 coffees or annually,
whichever is sooner, may be undertaken by the
user / operator.
• Maintenance every 30,000 coffees or every 2 years,
whichever is sooner, may only be undertaken by trained
personnel or by WMF Service, as in this instance
components affecting safety must be replaced.
• Revision after 6 years, may only be undertaken by
trained personnel or by WMF Service, as in this instance
components affecting safety must be replaced.

regulations. The WMF service engineers may only connect
the machine to existing prepared connection points. WMF
Service is neither authorized nor responsible for carrying
out any work on-site prior to connection.

range
230 V + 6 % - 10 %,
Mains voltage interruption < 50 ms: no interruption of function
Water supply
(Constant water supply
optional)
3 / 8 inch hose connector with main valve, and filter with 0.2 to
0.25 mm mesh size, on site.
Min. 0.2 MPa flow pressure at 2 l / min., max. 0.6 MPa.
Water temperature max. 35 °C.
The set of hoses provided with the new coffee machine and / or the new
water filter must be used. Do not use old hoses.
Water quality For drinking water with a carbonate hardness above 5 °dKH a WMF
scale filter should be installed upstream.
Water drain pipe Hose a min. DN 19, minimum downward slope of 2 cm / m
Ambient temperature + 5 °C to max. of + 35 °C (empty the water line in case of frost).
Maximum humidity 80 % relative humidity without condensation.
Do not use unit outdoors.
Degree of protection IP X0
Installing surface 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.
Installation clearances 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.
Installation dimensions of
the scale filter
See the user manual for the scale 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 device 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. If the mains connection lead for
this device is damaged then it must be replaced by our customer service personnel or a similarly qualified person. 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 mains cable must not come into contact with hot surfaces. The mains switch and plug
top are part of the customer‘s on-site installation. 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 screened 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)
