4. Functional description and device compo-
sition
4.1 Mode of operation
The HygroMatik steam humidifier utilizes the conductivity nor-
mally present in tap water for steam production. Electrodes
inside an enclosed steam cylinder are immersed directly into the
tap water. They are connected to the alternating current.
The conductivity of the water generates an electric current
between the electrodes. In this way, the electric power supplied
is converted directly into heat without energy loss.
The amperage is a function of the available voltage, the
immersed electrode surface area, the average distance between
the electrodes and the water conductivity. The steam output of
the humidifier is determined by electric power usage, which is
regulated by increasing or decreasing the immersed surface
area of the electrodes.
Concurrently, a self-regulating control keeps conductivity within
a specified range.
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 cylinder.
4.2 Structure and operation of the device
When the controller specifies an increase in humidity, the main
contactor is switched on and the electrodes (48) are supplied
with power. The water inlet solenoid valve (25) feeds water into
the steam cylinder (16+19).
As soon as the electrodes are immersed, the current begins to
flow. The water is now heated. When the pre-selected output is
reached, the control turns off the solenoid valve and interrupts
the water supply.
After a short heating up period, the water between the elec-
trodes begins to boil and vaporize. The vaporization lowers the
water level (W) in the steam cylinder, reducing the output pro-
vided. The inlet solenoid valve, equipped with a fine mesh filter,
intermittently admits fresh water.
Humidifier power usage is continuously monitored. With a cold
start-up, the nominal current increases to 12 % in order to
achieve quick-start output parameters. This activates the elec-
tronic overflow limiter which causes a partial draining of the cyl-
inder. This reduces the immersed surface area of the electrodes,
lowering power usage.

The concentration of dissolved salts increases over time, which
can lead to a rise in the conductivity of the water. If this contin-
ues, conductivity may increase until a short circuit occurs. This
could damage the unit, but in any case would significantly
reduce the life span of the electrodes.
For this reason, regular, periodic blow-downs of some of the
concentrated water are very important. Following this procedure
as recommended provides stable cylinder water conductivity as
well as minimal water loss for the expected service life of the cyl-
inder.
Water blow-down is performed by a blow-down pump (32). The
functioning of the blow-down pump is continuously monitored
during operation. If the pump is damaged, the steam humidifier
shuts down.
With normal water quality, the blow-down loss rate is between
7% and 15% of the amount of steam produced. The steam cylin-
der requires complete drainage every 3-8 days, regardless of
the water quality.
Mineral deposits settle in the open area below the electrodes
and are removed through periodic maintenance. The blow-down
pump itself has wide openings and can flush out smaller pieces
of mineral deposit. This extends the service life of the unit and
reduces the required maintenance interval.
During blow-downs, water flows from the pump into the drainage
system.
A sensor electrode (10) monitors the maximum
water capacity
of the cylinder. When the water level reaches the sensor elec-
trode, the water supply is interrupted. This can occur when the
water has low conductivity or when the electrodes are worn out.
In the case of low water conductivity, however, this state usually
lasts only a short time. The built-in control and the large area
electrodes combine to produce a rapid rise in conductivity by
increasing the concentration of the water.
The steam cylinder consists of a top (16) and lower (19) part
joined with a cylinder flange. The seal between the cylinder and
cylinder base (37), as well as between the top and lower part of
the cylinder, is maintained using an o-ring (35).
Risk of skin burns!
During operation and for at least 10 mins afterwards the steam
nozzle is hot!
Do not touch!

Page 15
Risk of scalding!
During operation hot steam discharges from the nozzle.
Avoid direct contact with the visible steam cloud.
Due to foaming within the cylinder caused by contamination hot
water may trickle from the nozzle.
Keep clear!
Rotating parts!
During operation the cross-flow fan rotates.
Do not touch or block the fan during operation.

Wall Mounting
The steam humidifier must be installed vertically in order to func-
tion properly. Positioning should be such that draught effects are
avoided. The minimum mounting height is 0.15m/ 5.9 inch above
floor level. However, in order to avoid the risk of scalding a
mounting height of 2m/79 inch is recommended.
Risk of foot injuries!
Unit can drop during mounting by a single person.
Helping hand of a second person is required.
» Position the steam humidifier in the planned location,
adjust with spirit level and mark position of hanging
bolts. See also "Equipment Dimensions".
» Hang the unit onto bolts screwed into the marked posi-
tion.
4.2 Unit Installation Check
Please check the installation using the following list:
Does unit hang vertically?
Are wall distances to the unit within the range
Is the unit installed in such a way that draught effects
are avoided?
Are all bolts and clamps tightened?

5. Water Installation
Risk of scalding!
Very hot water on the humidifier drain side!
Have all installation work done by expert staff in order to avoid
scalding hazards due to improper water guidance.
Risk of electrical shock!
Hazardous electrical high voltage!
Before starting installation work make sure that the unit is not
connected to the power supply.
General rules
•Obey local public utility
regulations
•Verify that necessary safety measures have been taken
to eliminate backflow of polluted water into drinking
water treatment facilities. This may require the installa-
tion of a system separator and free discharge into the
drainage system. Within the humidifier, a double check
valve (58) is incorporated in the water supply line. It
prevents the backflow of water. Alternatively, units are
available that feature a filling cup making further safety
measures obsolete
•Use feed water without chemical additives and with a
conductivity between 200 and 800 µS/cm only. Beyond
conductivity levels of 800 µS/cm up to a maximum of
1250 µS/cm and below conductivity levels of 200 µS/cm
to a minimum of
125 µS/cm, special adjustments are
required. In this case please contact your specialist
dealer
•Supply water temperature must not
exceed 40 °C/104
°F
•Allowable range of water pressure: 1 bar/14.5 psi min.,
10 bar max./145 psi max
•Blow-down water must drain freely

Page 20
5.1 Operation with Softened Water
Do not use softened water unless special measures are
taken!
When feeding softened water into the HygroMatik steam humidi-
fier, the aspects outlined below must be taken into account.
Softened water may cause
•unacceptably high conductivity
•the formation of salt bridges between the electrodes
and the electrode leads on the inner surface of the top
part of the steam cylinder
•foaming in the steam cylinder
Salt bridges cause electrical arcs. These are indicated by the
presence of black grooves in the top part of the cylinder. The cy-
linder must then be replaced to prevent further damage to the
cylinder material, as well as short circuits which trip main circuit
breakers.
Foam comes into contact with the maximum water level sensor
electrode and triggers a signal indicating the cylinder is filled to
capacity, even though this is false and the nominal current has
not yet been reached.
Recommendations
If using a water softening system, we recommend diluting the-
softened water with normal tap water to produce an overall hard-
ness between 4-8°dH/71-142 ppm. This value can be set lower if
the water does not foam.
When blending softened water with deionized water (conducti-
vity = 5-20 µS/cm) it must be ensured that the mixture neither
foams nor is too low in conductivity.
When feed water contains softened water, the level of conducti-
vity is typically higher at operating temperature.
