Important notes on maintenance

Qualification of personnel

All maintenance work must be carried out only by

well qualified and trained

personnel authorised by the owner

. It is the owner’s responsibility to verify

proper qualification of the personnel.

General note

The instructions and details for maintenance work must be followed and

upheld.
Only the maintenance work described in this documentation may be car-

ried out.
Only use original Nordmann spare parts to replace faulty parts.

Safety

Some maintenance work requires removal of the unit cover. Please note

the following:

DANGER!

Danger of electric hazard!

You may get in touch with live parts when the unit is open. Touching live

parts may cause severe injury or even lethal violation.

Prevention: Before carrying out any maintenance work set the Nordmann

ES4 4 out of operation as described in chapter 5.5 (switch off the unit,

disconnect it from the mains and stop the water supply) and secure the

unit against inadvertent powerup.

CAUTION!

The electronic components inside the humidifier are very sensitive to

electrostatic discharge.

Prevention: Before carrying out any maintenance work to the electrical

or electronic equipment of the humidifier, appropriate measures must be

taken to protect the respective components against damage caused by

electrostatic discharge (ESD protection).
