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 espresso machines meet the requirements described
above. If care of the espresso 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:
Sterilize 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.
HACCP schedule
“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
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.
Recommendation:
Only use UHT milk with a
1.5% fat content.
Page 50
50
User manual WMF bistro!
HACCP schedule
Keep milk cool.
• Always have a new pre-refrigerated milk pack handy.
If a pre-refrigerated freshly opened pack is used within •
a period not exceeding 3 hours, refrigeration during use
is not necessary.
If little milk is being used, pre-refrigerated milk must be •
replaced in the refrigerator again during operation.
At commencement of operation
milk should b e at approx . 43-46 °F
(6 - 8 ° C).
Depending on the setting, one litre
of milk is suffi cient for approx.
20 cappuccinos .
WMF AG offers a range of
refrigeration options (e.g., WMF
countertop coolers or WMF milk
coolers).
HACCP schedule
Use only cooled UHT milk as otherwise health risks due to microbacteria cannot be excluded!
For Choc use only products which are not past their sell-by date.

Appendix: Technical data
It may be necessary to also observe additional country-specific
regulations.
The lo cal p ower supply must be constructed according to NEC . To improve
safet y, the espresso machine should be fitted with an FI 30 mA earth leakage
current circuit breaker complying with EN 610 08. Near the machine or ab out
12 inch (30 cm) below the counter top there should be a shockproof socket
as a single-phase connection installe d loc ally on the rear or side wall of the
counter substructure or a country-specific single-phas e 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. If the mains connection lead for
this espresso machine is damaged then it must be replaced by our customer
service personnel or a similarly qualified person. If the espresso machine is
permanently connecte d to the mains then an all-pole disc onnecting separator
(mains switch) according to EN 60947 with a minimum ⅛ inch (3 mm) contact
gap must be installed. A separator switch is recommended for a flexible
conne ction. 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)
