6.3
Operating conditions
It is assumed that the planning of the system, as well as installation, setting in operation
and maintenance works are executed by sufficiently instructed staff and that these works
are checked by responsible specialists. The details on the machine's type plate must
match those of the standard drawing and the local connection conditions.
Conditions to be provided by the customer:
Frost free storage and installation area
Electrical connection in accordance with the dimensional drawing
Fresh water connection in accordance with the dimensional drawing
Waste water connection in accordance with the dimensional drawing
Anti-slip floor coverings should be provided around the dish-washing appliance.
6.3.1 Requirements to the installation area
Ensure that the storage and installation area is permanently frost free.
The machine is only frost-proof in as-delivered state or if equipped with special fea-
tures (option: frost drainage).
If the machine is installed in an area where the surrounding temperatures are below 0°
C, water freezing inside the machine damage the internal water circuit components
(pump, solenoid valve, boiler, etc.).
6.4
Requirements for the electrical connection
The correct voltage and type of current must be available
Safeguard the power supply cable according to regulations and provide it with a
power disconnection device in the fixed electrical installation.
The machine must be connected to a potential equalisation system!
If an unearthed neutral (N) is used with alternating current, the power disconnec-
tion device must have 4-poles (with alternating current 2-poles).
For connection to three-phase current a 5-pole terminal strip (L1, L2, L3, N, PE)
must be used.
Electricity supply without neutral conductor (N): when connecting to three-phase
current, use a 4-pole clamping strip (L1, L2, L3, PE).
Conductor colours: live conductor L1 = black/1, L2 = brown/2, L3 = grey/3, neutral
conductor N = blue/4, ground wire conductor PE = green-yellow.
Current applicable standards and requirements of local utility companies are to be
adhered to with regard to protective measures and connection of the potential com-
pensation system.
The products are intended for permanent connection to the on-site power supply and
have been tested for the market accordingly. Any other form of electrical connection is
to be established by a licensed electrician.
Do not connect any additional consumers to the fuse protecting the machine.
Re-tighten all terminal fixing screws before the setting in operation.
The wiring diagram is behind the warewashing machine's front panel. The enclosed
wiring diagram must remain in the machine.
Design and construction subject to change without prior notice!
