1.4 Intended Use
The kit serves for steam production based on
tap water or partially softened water.
Only use supply water featuring a con-
ductivity of 125 to 1250 µS/cm.
D1: Lower threshold
C1: Range of reduced conductivity
(adjustment required)
A: Normal Tap water
B: Range of increased conductivity
C2: Range of high conductivity
(adjustment required)
D2: Upper threshold
In the C1 and C2 ranges, adaptation of the
periodic blow-down frequency may be
required.
Proper usage also comprises the adherence
to the conditions specified by HygroMatik for:
• installation
• dismantling
• reassembly
• commissioning
• operation
• maintenance
• disposal.
Only qualified and authorised personnel may
operate the unit. Persons transporting or
working on the unit must have read and
understood the corresponding parts of the
Operation and Maintenance Instructions and
especially the chapter 2. „Safety Notes“.
Additionally, operating personnel must be
informed of any possible dangers. You
should place a copy of the Operation and
Maintenance Instructions at the unit‘s opera-
tional location (or near the unit).
By construction, the kit is not qualified for
exterior application.
Risk of scalding!
Steam with a temperature of up to 100 °C is
produced.
Do not inhalate steam directly!
1.5 Possibility of certification
HygroMatik humidifiers are certified accord-
ing to the household appliance standard DIN
EN 60335-1 in accordance with the special
requirements for humidifiers DIN EN 60335-
2-98 and comply with the requirements of the
EC Low Voltage Directive 2014/35/EU con-
tained therein.
It has been shown by the legislator through a
risk analysis in accordance with the Machin-
ery Directive that the risks are mainly of elec-
trical origin and that all essential safety
requirements of the Machinery Directive
together with the main objectives of the Low
Voltage Directive are covered by the EN
60335-2-98 standard.
HygroMatik humidifier installation kits corre-
spond in their construction to the certified
humidifiers. Due to the lack of enclosure, wir-
ing and only optional control, they are incom-
plete in the broader sense, but not an
incomplete machine in accordance with the
Machinery Directive 2006/42 / EC.

2. Safety Instructions
These safety instructions are required by law.
They promote workplace safety and accident
prevention.
2.1 Guidelines for Safe Opera-
tion
2.1.1 Scope
Comply with the accident prevention regula-
tion „DGUV Regulation 3“ to prevent injury to
yourself and others. Beyond that, national
regulations apply without restrictions. This
way you can protect yourself and others from
harm.
2.1.2 Unit control
Do not perform any work which compromises
the safety of the unit. Obey all safety instruc-
tions and warnings present on the unit.
In case of a malfunction or electrical power
disruption, switch off the unit immediately and
prevent a restart. Repair malfunctions
promptly.
Restricted use.
IEC 60335-1 stipulates as follows:
This device may be used by children of eight
years of age and above as well as by persons
with reduced physical, sensory or mental ca-
pabilities or lack of experience and knowledge
so long as they are supervised or have been
instructed regarding the safe use of the de-
vice and understand the hazards that may re-
sult from it. Cleaning and user maintenance of
the unit must not be undertaken by children
without supervision.
The following applies to the HygroMatik
installation kits:
Ensure that the system/machine in which the
HygroMatik installation kit will be installed fully
complies with the provisions of the directives
(2006/42/EC) and the EMC directive 2014/30/
EU and that all safety-relevant functions have
been implemented in the control system.
2.1.3 Unit Operation
Risk of scalding!
Uncontrolled hot steam escape in case of
leaking or defective components possible.
Switch off unit immediately.
For Ministeam devices applies:
Risk of scalding!
No persons may be under the cloud of steam
blowing out (at a distance of approx. 1 m/40
inch in the direction of blowing out and 0.5 m/
20 inch on both sides of the device).
Risk of material damage!
• The unit may be damaged if switched
on repeatedly following a malfunction
without prior repair. Rectify defects
immediately!
• The unit must not be operated on a DC
power supply.
• The unit may only be used connected
to a steam pipe that safely transports
the steam (not valid for MiniSteam
units).
• Regularly check that all safety and
monito-ring devices are functioning
normally. Do not remove or disable
safety devices.
• Steam operation is only allowed when
the unit cover is closed.
Water leaks caused by defective connec-
tions or malfunctions are possible.
Water is constantly and automatically filled
and drained in the humidifier. Connections
and water-carrying components must be
checked regularly for correct operation.

2.1.4 Mounting, dismantling, mainte-
nance and repair of the unit
The HygroMatik steam humidifier is IP20 pro-
tected. Make sure that the unit is not object to
dripping water in the mounting location.
Installing a humidifier in a room without water
discharge requires safety devices to protect
against water leakages.
• Use genuine spare parts only
• After any repair work, have qualified
personnel check the safe operation of
the unit
• Attaching or installing of additional
components is permitted only with the
written consent of the manufacturer
Do not install HygroMatik steam generators
above electrical equipment such as fuse
boxes, electrical appliances, etc. In the case
of a leakage, leaking water can damage the
underlying electrical equipment
2.1.5 Electrical
Risk of electrical shock!
Hazardous electrical voltage!
Any work on the electrical system to be per-
formed by certified expert staff (electricians
or expert personnel with comparable training)
only.
Steam operation may only be started when
the unit cover is closed.
During maintenance or installation work, the
device must be disconnected from the power
supply and secured against being switched
on again. The absence of voltage must be
ensured by a measurement.
Leaks can cause leakage currents. Observe
safety regulations on working with voltage
parts (applies to electrode steam humidifi
es).
After electrical installation or repair work, test
all safety mechanisms (such as grounding
resistance).
Use only original fuses with the appropriate
amperage rating.
Regularly check the unit‘s electrical equip-
ment. Promptly repair any damage such as
loose connections or burned wiring.
Responsibility for intrinsically safe installation
of the HygroMatik steam humidifiers is
incumbent on the installing specialist com-
pany.

4. Functonal Description and
Device Composition
4.1 Mode of Action
Making use of the frictional heat caused
by current flow in a water tank
The HygroMatik electrode steam humidifiers
utilize the conductivity normally present in tap
water for steam production. Electrodes inside
an enclosed steam cylinder are immersed
directly into the tap water. They are con-
nected to the alternating current.
The conductivity of the water generates an
electric current between the electrodes. In
this way, the electric power supplied is con-
verted directly into heat without energy loss.
The steam produced has a temperature of
about 100°C (212°F) with minimal excess
pressure ("pressureless steam"). It is largely
free of minerals and germ-free. Mineral
deposits typically remain behind in the cylin-
der.
4.2 Mechanical Construction
The kit is designed for wall mounting or for
standing on a horizontal level surface.
The device composition is demonstrated by
the fig. following hereunder.
For maintenance purposes, the steam cylin-
der is separable in the middle.
