1. Introduction
Dear Customer,
Thank you for choosing a HygroMatik nozzle
system LPS. „LPS“ stands for „Low Pressure
System“, i.e. , in question is a nozzle system
that is operated with low pressure (5 to 15
bar).
The HygroMatik nozzle system LPS (referred
to hereafter as „nozzle system“) represents
the latest in humidification technology.
In order to operate the nozzle system safely,
properly and efficiently, please read these
operating instructions.
Employ your nozzle system only in sound
condition and as directed. Consider potential
hazards and safety issues and follow all the
recommendations in these instructions.
If you have additional questions, please con-
tact your expert dealer.
For all technical questions or spare parts
orders, please be prepared to provide unit
type and serial number (see name plate on
the unit).

1.3.2 General Symbols
This symbol is used whenever a situation
requires special attention beyond the scope
of safety instructions.
1.4 Intended Use
The nozzle system is used for air humidifica-
tion and cooling with desalinated water hav-
ing a conductivity of 5-20 µS/cm.
Proper use includes fulfilment of the assem-
bly, disassembly, reassembly, start-up, oper-
ating and maintenance conditions specified
by us as well as disposal measures.
Only qualified and personnel may work on or
with the system (a supplementary qualifica-
tion according to VDI 6022 Part B or an
equivalent qualification is recommended).
Persons transporting or working on or with
the system must have read and understood
the relevant parts of this operating manual,
particularly the 'Safety instructions' section.
Staff must also be informed of possible haz-
ards by the operating company. Please keep
a copy of the operating manual at the loca-
tion where the device is being used.
Applications:
The nozzle system has a wide range of appli-
cations. These systems are used wherever
low-energy adiabatic humidification or cool-
ing or systems with high-precision control are
needed. They can be found in such places as
offices, storerooms, production halls, clean
rooms, hospitals and concert halls.
Components installed in ventilation and air-
conditioning systems must be suitable for the
intended use; i.e., according to VDI 6022 or
equivalent, they must be corrosion-resistant,
easy to clean, accessible and hygienic. Fur-
thermore, they must not facilitate growth of
micro-organisms.
Improper use:
Any other use not compatible with the
intended use outlined above is not allowable.
Improper use as well as changes in hardware
or software that are not authorized by Hygro-
Matik will lead to the total loss of guarantee
and warranty claims.
Operating conditions must be met at any
time!
• The nozzle system is not frost-proofed
and not suitable for outdoor installation
• The room temperature should lie
between 5 and 40 °C
• When attempting to operate the system
in a position higher than 1000 m above
sea level, pls. talk to HygroMatik prior
to installation
• The pressure level of the nozzle
system must not be changed without
the consent of HygroMatik GmbH
• The nozzle system must not be used
for cold water cooling without the con-
sent of HygroMatik GmbH
• The nozzle system must not be opera-
ted with a vertical flow without the con-
sent of HygroMatik GmbH
For hygienic reasons, the feed water tempe-
rature should not exceed 15 °C.

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.
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

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.
2.1.3 Unit Operation
Health hazard due to the inhalation of
aerosols.
During operation of the HygroMatik nozzle
system LPS, it is not permitted to stay in the

2.1.4 Mounting, dismantling, mainte-
nance and repair of the unit
The nozzle system is IP20 protected. Make
sure that the unit is not object to dripping
water in the mounting location.
• Installing a nozzle system in a room
without water discharge requires safety
devices that cut-off the water supply in
case of 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
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.
Disconnect unit components from electrical
power supply prior to work.
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.
