The technology makes the difference.
Pluggit's value-added innovations for man and the environment.
Appetite for fresh air? You can get more information on the company,
the intelligent technology of Pluggit comfort ventilation systems,
references and regional contacts at
www.pluggit.com or as an on-line dialogue at www.lueftungsblog.de
The air conduct being installed invisibly in the floor and an ideal
positioning of the air outlets make for perfectly aligned transverse
ventilation. Displacement ventilation means that the fresh air is
supplied to the room almost without causing any draughts and
disturbing noise, without pressure and preheated during the
cold months.
Fresh air and heat supply in one - quicker, more flexible and more
energy saving than common heating systems.
allfloor – in ceilings, walls, above or under concrete and screed -
the Pluggit system design offers maximum flexibility with regard to
the installation of the ventilation ducts and thus is ideal for the use
in new buildings as well as for the refurbishment of
existing buildings.
This innovative technology allows for the supply of exactly the
required or desired amount of fresh air thanks to a highly sensitive
sensor system and control. Cost and time saving, the unit adapts to
the system characteristics at the touch of a button after the
installation and automatically calibrates itself consistently at
regular intervals.
Energy efficiency - a high heat supply rate alone makes a ventilation
system seem effective and energy efficient only at first glance.
The decisive factor for an assessment is rather the ratio of the
energy spent to the attained heat recovery rate - the so-called
electrical energy efficiency. Due to a high tightness, a consumption-
optimised device design and the latest heat exchanger technology,
our ventilation systems attain excellent ratings in terms of heat
recovery and energy efficiency.
The CleanSafe principle guarantees a very low pollution potential of
our distribution system due to smooth surfaces and a trouble-free
cleaning concept, the convincing results of which have been
confirmed by an independent testing institute.
Appetite for fresh air in your building?
The unique comfort ventilation system for the energetic
refurbishment of existing buildings.

2.1. INTENDED USE
The humidifier serves to increase the humidity in the room
air by means of water vapour. For this purpose water from
the existing drinking water system is fed into the humidifier.
2.2. UNINTENDED USE
Any use other than that described in "Intended use" shall
not be permissible.
Do not install the humidifier outside due to the risk of frost
and rain.
Temperatures must not exceed 40 °C where the humidifier
is placed.
Do not install the humidifier next to or above devices sensi-
tive to water.
2.3. WARRANTY
In order to preserve your full statutory warranty claim, the
technical guidelines in these operating and installation in-
structions must be observed.
Only original Pluggit components and original Pluggit spare
parts must be used.
2.4. FUNCTIONING/OPERATING PRINCIPLE
The water is converted to water vapour in a steam cylinder
with electrode heating. For this purpose the water is in-
serted through an inlet valve and a filling system in the
steam cylinder. When the electrodes come into contact with
the water, they cause an electric current to flow. The water
is heated up until it evaporates.
The evaporation takes place at very low pressure.
Water is inserted in the steam cylinder until the required
steam output is reached. Subsequently, the inlet valve will
automatically close.
When the minimum current level is reached, the inlet valve
will open and water will again be inserted in the steam cyl-
inder.
Due to the evaporation, the conductivity of the water in the
steam cylinder increases. Perfect adaptation to the indi-
vidual quality of the used water and the required steam
output is carried out fully automatically.
Thanks to this auto-tuning of the optimal water concentra-
tion in the steam cylinder, a change in the steam output can
be reached by means of even minimal variations of the
water level.
Pluggit recommends that you check the flow-calming sec-
tion during the humidifying season.
1. GENERAL SAFETY INFORMATION
Warning:
The following safety instructions must be observed,
since damage and injury may otherwise result:
zPlease read these installation instructions care-
fully before installing, operating and maintaining
the unit.
zThe installation and all electrical work must only
be carried out by qualified expert personnel.
zWhen installing and commissioning the humidi-
fier, observe all necessary legal and national re-
quirements (accident prevention regulations and
generally accepted codes of practice) and comply
with them.
zThe local rules concerning the connection of de-
vices to the pressure and wastewater system
must be observed.
zDo not start running the humidifier before all in-
stallation work is completed.
zWhen operating the humidifier, all covers must
be closed.
zDo not place combustible liquids or inflammable
material in immediate proximity to the humidi-
fier while it is running.
zDamages resulting from inappropriate storage
of the product, improper installation and han-
dling, insufficient maintenance or unintended
use are excluded from any liability.
zTechnical changes reserved.
2. GENERAL NOTES
Note:
It is not recommended that you use chemically treated
water or water from water softening and desalination
plants.
Note:
In case of information provided by the local water utility
company on, e.g. environmental pollution of the water,
the humidifier must be switched off.

3.2. NOTES ON THE INSTALLATION
• Choosing the right place for the humidifier:
•Vibration-free.
• Water-protected.
• Free from temperature fluctuations.
• Near the humidifying line.
• As close as possible to the room ventilation unit.
• Water and wastewater connection available.
• Before installing the humidifier, take the distances to
ceiling, ducts and wall into account in order to provide
for any additional material if necessary.
• The humidifier must be freely accessible for all mainte-
nance work.
• The humidifier and the humidifying line must be fixed to
a bearing wall or ceiling respectively.
When fixing the humidifier to plasterboard, appropriate
fixing material must be used.
• The humidifying line must be installed horizontally.
• Connect the humidifier using the shortest possible
steam hose (1.5 m) and few bows to the humidifying line.
Shorten steam hose if necessary. A 5-meter steam hose
is available as an option.
• Protect the steam hose against external influences such
as bending and deformation.
• Avoid condensate pockets in the steam hose.
• Install an aquastop (not included in delivery) as safety
device.
• If no fine filter is installed at the water meter, Pluggit
recommends that you install one before installing the
humidifier.
• Install a funnel or siphon for the discharge of conden-
sate and blowdown water. When the condensate is dis-
charged into a funnel, a minimum slope of 5 % must be
observed.
• The water pressure in the line for the water supply must
be 1-10 bar. When it is above 10 bar a pressure reducing
valve must be installed and set to 4 bar.

3.3. SAFETY FUNCTION
The humidifier is protected against dry running. The current
flow automatically stops as soon as the electrodes in the
Should the current consumption significantly exceed the
nominal value (+ 25 %), the inlet valve will automatically
open. Since the immersion depth of the electrodes in the
water is consequently reduced, the current consumption
falls back to the nominal value.
Should the current consumption, even after repeated
draining of the water, still exceed 140 % of the nominal cur-
rent, the humidifier will automatically switch off after a
short period of time.
3.4. REMOTE INDICATION (OPTIONAL)
Thanks to an additional board with floating relay output,
system messages can be displayed on a central building
control system (BCS).
