hACCP Cleaning Schedule
Chapter 6 hACCP Cleaning Schedule
You are required by law to ensure that your customers
are subject to no health risks as a consequence of con-
sumption of food substances you serve.
“Food Hygiene Ordinance”
of 05.08.1997“
An 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,
Use our
HACCP Cleaning Schedule for
monitoring of regular cleaning.
cutomer care, servicing and cleaning WMF coffee
machines meet the requirements described above. If
customer care of the coffee machines are 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:
Sterilize the Milk System daily
• Adhere to the cleaning instructions for the milk
system contained in the User Manual. This will ensure
that your system contains minimal bacteria at com-
mencement of operation.
You can call up the history of the most recent cleaning
operations via the
information pad.
Always commence operation with a freshly opened
pre-refrigerated milk pack
• Original packaged UHT milk is usually free from harm-
ful bacteria. Always open a new pre-refrigerated pack
at commencement of operation.
• Ensure absolute cleanliness on opening the milk
pack. Dirty hands or implements when opening may
introduce germs.
Recommendation:
Use only UHT milk with a 1.5 %
fat content.
Keep milk cool!
• Always have a new pre-refrigerated milk pack handy.
User Manual WMF presto
4ꢀ
hACCP Cleaning Schedule
At commencement of
operation milk should be at
approx. 6 – 8 °C.
• If a pre-refrigerated freshly opened pack is used
within a period not exceeding 3 hours, refrigeration
during use is not necessary.
Depending on setting
one litre of milk is sufficent for
approx. 20 cappuccinos.
• If little milk is being used, pre-refrigerated milk must
be replaced in the refrigerator again during operation.
WMF AG offers a range of refri-
geration options
(e.g. WMF Countertop Coolers or
WMF Milk Coolers).
Recommendation for Choc/Topping (optional)
Regularly clean the product reservoir. See the instruc-
tions in the Customer Care chapter.
See chocolate/topping manufacturer‘s instructions.
Observe cleaning instructions in

Chapter 7 Maintenance
Please note that this is a professional coffee machine
which needs regular maintenence 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.
Customer Care and Maintenance intervals depend on the
machine workload and are notified to you on the display.
The coffee machine may continue to be operated after
the message but Customer Care or contract mainte-
nance should be carried out promptly to ensure correct
functioning and so as to avoid any consequent damage.

Safety
Chapter 9 Safety
9.1
hazards for the User
At WMF safety is one of the most essential product fea-
tures. The effectiveness of safety devices is only
warranted if the following points are observed:
• Read the User Manuals carefully prior to use.
• Do not touch hot machine components.
• Protect the machine from the elements
(frost, humidity, etc).
• Do not use the machine if it is not working properly or
if it is damaged.
• Do not allow children near the machine.
• Built-in safety devices must under no circumstances
be altered.
Failure to observe hazard
instructions can lead to serious
injury.
Despite safety devices every machine remains fraught
with hazards if incorrectly used. Please observe the
following notes when using the coffee machine so as to
prevent injury and health hazards:
Scald hazard!
When dispensing coffee or Choc, hot water and steam
there is a danger of scalding. Ensure that when dispens-
ing drinks there is always a receptacle under the outlet.
Attention! Scald Hazard
Near outlet!
Burn hazard!
The brewing unit must only be cleaned when the machine
is cold. The brewing unit can get hot.
Attention! Burn Hazard !
Hot Surfaces!
Bruising or Crushing hazard!
There is a danger of bruising or crushing when handling
all moving parts!
Attention! Risk of Crushing!
When the coffee machine is switched on do not reach
into the bean hopper or the brewing unit opening.

combi spout during cleaning/decalcification.
Attention! Danger of irritation or
scalding near outlet !
9.2
Danger to the Machine
Please observe the following points so as to prevent
problems with and damage to the coffee machine:
• With water with a carbonate hardness in excess of
5°dCH a WMF anti-scale filter should be fitted other-
wise the machine can be damaged due to build-up of
scale.
• For insurance reasons always ensure that, at the end
of operation, the mains water tap for water supply
(plumbed machines) is turned off and the mains power
is switched off or the machine unplugged.
• We recommend damage prevention measures:
- e.g. installation of a suitable water monitor in the
mains water supply
- fitting smoke detectors.
• After lenghty periods out of use cleaning must be
carried out prior to putting into operation.
User Manual WMF presto

Safety
• Do not expose the coffee machine to frost.
• After a break in operation of several weeks we recom-
mend running the cleaning mode at least twice.

Inbuilt clearances
For operating, service and safety reasons the
machine should be installed with clearance of not
less than 50 mm at the back and sides from the
building or non-WMF components.
A clear height of 100 mm from the top of the sup-
porting surface should be ensured. Recommen-
ded height of the working surface is a minimum of
850 mm from floor level.
If the machine connections are to be routed down
through the counter, remember also to allow
space for the connections. These may restrict the
available space below the machine.

* The existing electricity supply must conform to the currently valid national rules (for Germany, VDE 0100).
To improve safety the coffee machine should be fitted with an FI 30 mA earth leakage current circuit breaker
to EN 61008 standards. A plug top wall socket should be fitted near the machine. If the mains connection
lead of this coffee machine is damaged it must be replaced by WMF Customer Services or a similarly qualified
person.
If the coffee machine is permanently connected to the mains then an all-pole disconnecting separator (mains
switch) to EN 60947 standards with a minimum 3 mm contact gap must be included. For flexible connection a
separator switch is recommended.
Mains cable must not come into contact with hot surfaces.
Mains switch and plug top are part of the customer‘s on-site installation.
The machine may not have a fixed permanent mains connection if installed on any mobile furniture item.
