10. Commissioning
Commissioning may only be carried out by a
qualified WARNING Electrocution contractor in
accordance with safety regulations.
The high limit safety cut-out will trip if you fail to
follow the correct sequence (first water, then power)
with the 2 kW appliance. Proceed as follows:
Fill the appliance with water.
Briefly disconnect the appliance from the power
supply.
Either open the DHW valve of the tap or set the mono
lever mixer tap to "hot" until the water that flows out is
free of bubbles.
Insert the plug into the standard socket or set the
fuse/MCB in the fuse box. Select a temperature.
10.1.1 Appliance handover
Explain the functions of the appliance to the user. Show
the user how to operate the appliance. Make the user
aware of potential dangers, especially the risk of scalding.
Hand over these instructions and, if applicable, the
instruc-
tions for any accessories.
10.2 Recommissioning
See chapter "Installation / Commissioning / Initial start-up".
11. Settings
11.1 Setting the temperature limit
2 Temperature selector
Placing the limiting ring behind the temperature selector allows
you to limit the setting range of the temperature selector to a
specific maximum temperature. Turn the temperature
selector to zero (fully anti-clockwise to "°C"). Pull off the
temperature selector and the limiting ring. Push the limiting
ring with the required maximum setting onto the controller
shaft. Install the temperature selector set to zero (°C).
12. Shutdown
Isolate the appliance from the power supply by removing the
plug or by tripping the fuse/MCB in the fuse box. Drain the
appliance (see chapter "Installation / Maintenance / Draining
the appliance").
