1.1

 

Ground Connection 

The first operation of each installation is the correct ground connection for the equipment, 
following the safety regulations of the state and at the time when the equipment is installed. 

1.2

 

Thermo-hygrometric conditions of the installation 

Check that the environmental conditions of the place where the installation is carried out are 
always compatible with the requirements of the product as indicated in this manual. ELSTEAM 
products cannot be installed exposed to weather conditions or frost, unless different conditions 
explicitly expressed in countersigned documents. 

1.3

 

Electrical Connections 

ELSTEAM equipment must be connected to the power supply by carefully following the local 
regulations and the specifications on the plates of the equipment. 

In particular, it is mandatory that the power supply lines have a correct section and are equipped 
with a standard disconnecting switch with differential safety (life-saving device) capable of 
protecting the user not only against the device, but also against the power lines installed. 

1.4

 

Hydraulic Connections 

It is necessary to strictly comply with the local actives regulations (for installation) and make sure 
that any breakages or water leaks deriving from the installation or from the units itself cannot 
cause damage to the environment or to third parties. Do not install the equipment on passageways 
or over dangerous or susceptible objects and always provide special drainage systems that can 
evacuate any spilled water correctly. 

1.5

 

Steam distribution 

ELSTEAM humidifiers emit steam. When installing steam distribution network, carefully follow 
directives provided in the concerned section of the user manual. The installer must verify that any 
failure of the distribution network cannot cause damage to people or property. 

1.6

 

Mandatory procedure for switching off the humidifier for long periods 

The new VDI 6022 standard requires the user to make sure that there are no water deposits in the 
system that are not used for long periods. 

If the humidifier is switched off simply by switching the power switch (red button on front panel), 
there may be a deposit of water in the kettle. 

To overcome this inconvenience, in the event of an expected long shutdown of the humidifier (for 
example for the summer season, it is necessary to proceed by following the procedure: 

 

 

Set to zero the request signal 

 

Turn OFF the humidifier (using the red button on front panel) 

 

Turn ON the humidifier (using the red button on front panel) 

 

Wait for the kettle to empty completely 

 

Check that no red signals remain on 

 

Proceed to turn OFF the power switch. 

1.7

 

Drain connection 

ELSTEAM appliances must be able to discharge water with any limescale deposits or evaporation 
residues.
