Danger that may arise from the unit

DANGER!

Danger of electrical shock!

The Nordmann RC4/DC4 is mains powered. One may get in touch with live parts when the

unit is open. Touching live parts may cause severe injury or danger to life.
Prevention:

Before carrying out any work set the Nordmann RC4/DC4 out of operation as de-

scribed in chapter 4.3 (switch off the unit, disconnect it from the mains and stop the water supply)

and secure the unit against inadvertent power-up.

WARNING!

Hot water vapour - Danger of scalding!

The Nordmann RC4/DC4 produces hot water vapour. There is danger of scalding when get-

ting in touch with hot water vapour.

Prevention:

Do not carry out any work on the steam system during operation (steam lines, steam

distributor, etc.). If the steam system is leaky set the Nordmann RC4/DC4 immediately out of op-

eration as described in chapter 4.3. Correctly seal the steam system before putting the unit into

operation again.

WARNING!

Danger of burning!

During operation the components of the steam system (steam cylinder, steam distributor, etc.)

get very hot (up to 100 °C). There is danger of burning when touching the hot components.
Prevention:

Before carrying out any work on the steam system set the Nordmann RC4/DC4 out of

operation as described in chapter 4.3, then wait until the components have cooled down sufficiently

thus preventing danger of burning.

Behaviour in case of danger

If it is suspected that

safe operation is no longer possible

, then the Nordmann RC4/DC4 should

immediately

be shut down and secured against accidental power-up according to chapter 4.3

This can be the case under the following circumstances:

– if the Nordmann RC4/DC4 or its mains cable is damaged

– if the Nordmann RC4/DC4 is no longer operating correctly

– if connections and/or piping are not sealed
All persons working with the Nordmann RC4/DC4 must report any alterations to the unit that may

affect safety to the owner without delay.

Prohibited modifications to the unit
No modifications must be undertaken

on the Nordmann RC4/DC4 without the express written

consent of the manufacturer.
For the replacement of defective components use exclusively

original accessories and spare parts

available from your Nordmann supplier.
