							A Warning and Safety Instructions
1 General Information
x
Danger!
•The machine should not be installed or operated in any area where there is
a risk of explosion or possibility of freezing conditions.
•The operator is responsible for ensuring that all containers are clearly
marked with suitable warnings when detergents and disinfectants are
transferred from large containers into smaller ones for use at the installation
site.
•The warnings and instructions on detergent and disinfectant containers
must be followed closely. These chemicals may be corrosive and can cause
irritation. Protective gloves and goggles must be worn.
•Organic solvents should never be used, because there may be a risk of
explosion in certain conditions.
•Inhalation of powder detergents must be avoided. If detergents are
swallowed or inhaled they may cause burning in the mouth and throat, and
may even inhibit breathing.
•If the machine is being used for decontamination as ordered by the
authorities, then the steam condenser and its connections to the cabinet
and the drain must be disinfected with a suitable agent whenever any
repairs are carried out or parts replaced.
•Water in the machine is not suitable for drinking.
•If the machine has been operated with high temperatures (> 158°F/70°C),
then there is a risk of scalding when it is opened. Baskets and inserts
should be allowed to cool before removal. Hot-water residues from
containers in the cabinet should be drained off carefully.
•Washer-disinfectors are not splash-protected, so they and their immediate
surroundings must not be cleaned with water hoses or high-pressure
cleaners.
•Before starting any service work, disconnect the machine from the power
supply. Measures must be taken to ensure that power cannot be switched
on again accidentally.
•Even with the machine shut off, voltage may be applied to some
components.
•When the casing is removed, sharp edges may be exposed and care must
be taken to avoid injury.

							Note
•Installation and setup may only be carried out by specially trained and
authorized technicians in accordance with all appropriate regulations.
•Servicing, modification, testing and maintenance of electrical appliances
should only be carried out in accordance with all appropriate legal
requirements, accident prevention regulations and valid standards. All
regulations of the appropriate utility supply companies and standards
relating to safety (not limited to electrical safety) are to be complied with.
•After any repair or service work, a general and model-specific visual and
operational check must be performed.
•On machines with a ground connection, touch current measurements are to
be performed on any conductive parts not connected to ground.
•When carrying out measurements on an electronic module connected to the
power supply, always use narrow measuring probes. Contacts are very
closely spaced and using thicker probes may cause undesired short
circuits.
•Electrical connection should be made via a suitable isolator, with an“On/
Off”button easily accessible for service work.
•Washer-disinfectors whose wash programs are controlled by a
programmable electronic control mayonlybe serviced and repaired by
specially trained Medical Product Advisers in accordance with all applicable
medical product regulations. Every software modification or repair of
components affecting disinfection parameters (temperature, contact time,
etc.) must be recorded in a protocol. For more information, see the
appropriate medical product book.
