1.1 Symbols used
This symbol warns of situations where a safety risk may arise. The instructions
given should be followed in order to prevent injury and dangerous situations.
This symbol on a machine part warns of electrical equipment. The machine must
be entirely non-live during servicing, turn off the power at the power switch and if
required, the switch should be locked to prevent unintentional operation. The
component may only be removed by a qualified electrician.
This symbol warns that the machine’s electronics are sensitive to electrostatic
discharge (ESD), which is why a static electricity wristband must be used when
handling the electronics at all times.
This symbol explains the right way to perform a task in order to prevent poor re-
sults and/or damage to the machine.
This symbol identifies recommendations and hints to help you get the best results
when washing, to increase the machine’s lifespan and reduce the risk of emer-
gency shutdown.
This symbol explains the importance of careful and regular cleaning of the ma-
chine to meet hygiene requirements.
This symbol warns of the importance to read the manual before using the ma-
chine.
This symbol warns that local regulations must be followed for recycling of pack-
aging etc. as well as the destruction of the machine.
This symbol shows where any earth cable for potential equalisation can be con-
nected. The earth bolt is placed on the machine’s stand.

1.2 Machine rating
The machine has two rating plates, one of which is placed at the bottom of one
side of the machine and the other in the electrical cabinet. The technical informa-
tion on the plates is also included on the machine’s wiring diagram. The various
rating fields show:
1. Machine type
2. Machine serial number
3. Year of manufacture
4. Enclosure protection class
5. Voltage
6. Number of phases with or without neutral
7. Frequency
8. Main fuse
9. Motor output
10. Electrical heating output
11. Max. output
1.3 Checking that the machine and manual correspond
Check that the type description on the rating plate corresponds with the type de-
scription on manual cover page. If manuals are missing, it is possible to order new
ones from the manufacturer or the local distributor. When ordering new manuals,
it is important to quote the machine number found on the rating plate.

2. Safety instructions
Read the chapter GENERAL INSTRUCTIONS carefully before starting work.
2.1 General information
The machine is CE marked, which means that it complies with the requirements
of the EU Machinery Directive with regard to product safety. Product safety
means that the design of the machine will prevent personal injury or damage to
property. The CE mark is only valid for an unmodified machine. Any damage to
the machine arising from failure to follow the instructions will invalidate the sup-
plier’s warranty and product liability.
Installation, repairs and servicing must be performed by an authorised engineer
in accordance with local and national rules in effect for such work with water and
drainage systems, electricity, ventilation and steam. To ensure electrical safety,
components must only be tested when installed in their normal place in the ma-
chine. We recommend that the work is performed by the manufacturer or one of
the manufacturer’s authorised service companies.
To further improve safety during installation, operation and servicing, the operator
and the personnel responsible for installing and servicing the machine should
read the safety instructions carefully.
The machine’s electronics are sensitive to electrostatic discharge (ESD), which is
why a static electricity wristband must be used when handling the electronics at
all times.
Before the machine enters service, ensure that the personnel are given the nec-
essary training in handling and looking after the machine.

In order to avoid dangerous situations, the following must be followed:
• Switch off the machine immediately in the event of failure or malfunction.
• Make sure the machine is non-live before removing the cover plate. Turn
off the power using the power switch. If required, the switch must be locked
to prevent unintentional operation.
• Shut off the tap for incoming water and drain the machine’s tank(s) before
starting work. Let the machine cool down as pipes for water, washing
pumps, booster heaters and valves become very hot when the machine is
in operation.
• The machine and equipment requires an annual service. The machine
should be serviced by a person authorised or trained to do so by us. Use
original spare parts.
• Warranty repairs must be performed by an authorised company. Contact
an authorised service company to draw up a programme of preventive care
and maintenance. For authorised service companies, please see
www.wexiodisk.com or contact Wexiödisk AB.
• The regular checks described in the manual must be carried out in accord-
ance with the instructions.
2.2 Transport
Handle the machine with care during unloading and transport; there is a risk of it
tipping over. Never lift or move the machine without using the wooden packaging
to support the stand.
2.3 Installation
• The machine is designed for quick electrical installation.
• The machine must be connected to a lockable power switch.
• Make sure that the mains voltage is the same as that indicated on the ma-
chine’s rating plate.
For increased safety, it is recommended to equip the installation with a ground
fault circuit breaker.
2.4 Detergent and drying agent
Be aware of the risks involved in handling detergents and drying agents. Protec-
tive gloves and safety glasses should be used when handling, and an eyebath
should be within easy access. Read the warning text on the detergent and drying
agent containers as well as the detergent supplier’s instructions.
