Preliminary Note:
A Word about Water and Atomising Systems
All atomising humidifiers operate based on the principle that water in the form of very fine aerosol
droplets may be atomised and subsequently evaporated.
Because tap water contains various components in addition to pure water (H2O), solids remain
behind after evaporation, such as calcium or other minerals. These form a fine dust in the area of
evaporation. The build up of dust can be prevented by using fully demineralised water. Reverse
osmosis systems, for example, are well-suited for this type of water treatment.
When drinking water is used, mineral deposits may form on the tip of the nozzle. These deposits
must be removed during regular maintenance. Maintenance work can be reduced by using fully
demineralised water.
Consult your HygroMatik specialists. We will answer any questions you may have concerning
water and advise you on the installation and initial operation of your HygroMatik atomising sys-
tem.

1. Introduction
Dear Customer,
HygroMatik vacuum nozzle systems represent the latest in
humidification technology.
They will impress you with their safety, ease of use and econo-
mical operation.
In order to operate your HygroMatik nozzle system safely, pro-
perly and efficiently, please read these operation instructions.
Employ your nozzle system only in sound condition and as
directed. Consider potential hazards and safety issues and fol-
low all the recommendations in these instructions.
If you have additional questions, please contact us:
Tel.: [phone] (switchboard)
Tel.: [phone] (technical hotline)
Fax: [phone]
e-mail: [email protected]
1.1 Directions for Use
The HygroMatik nozzle system with vacuum nozzles atomises
water with compressed air using injector technology and is inten-
ded for direct room humidification.
Warning: Use compressed air of breathable air quality only!
This meets Class 1 standards as specified in DIN ISO 85
Class 1 compressed air as specified by DIN ISO 8573-1
residual oil content 0,01 mg/m³
maximum dirt particle size 0,1 µm

Page 6
Note: The air filter for the nozzle system has a pore size of 5
µm; it acts as protection for the nozzle system against impurities
in the plumbing. To achieve breathable air quality, an extra filter
is required.
HygroMatik vacuum nozzles operate with drinking water. Fully
demineralised water must be used to prevent calcium and mine-
ral dust. Usage of fully demineralised water also lengthens main-
tenance intervals.
For the nozzle system, the following connections are needed at
the customer installation site:
Connections:
compressed air: 5-10 bar, 10/8 mm hosing
water: 2-4 bar, 10/8 mm hosing
electricity: 230V/1Ph/50 Hz
Proper usage also entails following HygroMatik's instructions for
installation, dismantling, reassembly, initial operation and opera-
tion and maintenance, as well as disposal procedures.
Only qualified, authorized personnel may operate or service the
unit.
Workers who transport or service the unit must have read and
understood the relevant sections of the operating instructions,
especially the section "Safety Notes." In addition, staff must
receive safety training about potential hazards from the operator.
Place a copy of the operating instructions at the location where
the unit is operated.

2. Safety Notes
2.1 Overview
These safety notes are required by law. They promote work-
place safety and accident prevention.
Warnings and Safety Symbols
The safety symbols below identify sections containing warnings
about hazards or potential dangers. Please familiarize yourself
with these symbols.
Warning: Failure to observe this warning may result in serious
injury or death and/or damage to the unit.
Danger, Hazardous Voltage: Hazardous electrical current! Fai-
lure to observe this warning may result in injury or even serious
injury or death
Warning: Failure to follow these instructions may result in
damage to the unit due to electrostatic discharge. The electronic
components of the humidifier control are very sensitive to elec-
trostatic discharges. In order to safeguard these components
during installation and servicing, steps must be taken to protect
against ESD.
Note: Materials and consumables must be handled and/or dis-
posed of as required by law.
Note: Appears before explanations or cross-references which
refer to other sections of the operating instructions.

2.2 Guidelines for Safe Operation
Overview
Observe all safety information and warnings which appear on
the nozzle system.
In case of a malfunction, switch off the nozzle system immedia-
tely and prevent a restart. Repair malfunctions promptly.
After any repair work, have qualified personnel check the safe
operation of the nozzle system.
Use original spare parts only.
Additional national safety regulations also fully apply to the ope-
ration of this nozzle system.
Accident Prevention Regulations
Warning: Comply with the accident prevention regulation
Accident Prevention Regulation Electrical Systems and Equip-
ment (VBG 4/BGVA2) to prevent injury to yourself and others.
Operating the Nozzle System
Do not perform any work which compromises the safety of the
nozzle system.
Regularly check that all safety and monitoring devices are func-
tioning normally.
Do not remove or disable safety devices.
Installation, Dismantling, Maintenance and Repair of the
Nozzle System
When performing maintenance or repair work on nozzle system
components, switch off power, shut off pressure and close off
water supply.
Attaching or installing additional components is permitted only
with the written consent of the manufacturer.

Electrical
Warning: Work on the electrical system must be performed by
qualified personnel.
If the electrical power supply malfunctions, switch off the control
unit immediately.
Use only original fuses with the appropriate amperage rating.
Regularly check the control unit's electrical equipment. Promptly
repair any faults, such as loose connections or damaged wiring.
After proper electrical installation or repair, test all safety mecha-
nisms (such as grounding resistance).
The control of theHygroMatik Nozzle System is IP55-protected.
Installing a humidifier in a room without water discharge requires
safety devices to protect against water leakages.
2.3 Disposal after Dismantling
Note: The operator is responsible for the disposal of nozzle sys-
tem components as required by law.
