Operation and Installation
4.1
Basic Requirements
For basic operational requirements of the HygroMatik nozzle
system, please read Section “Directions for Use”.
4.2
Sequence of Operation
When the hygrostat calls for an increase in humidity, the control
unit opens the pilot and vacuum valves by means of control air.
The nozzles are supplied with air and atomisation water.
At regular intervals, the control unit briefly switches off humidifi-
cation for self-cleaning. Inside the vacuum nozzle, elastic force
causes a stainless steel needle to spring forward; this action
detaches any calcium deposits that may be present in the atomi-
ser tip. When humidification resumes, the cleaning needle
retracts from the nozzle tip.
The HygroMatik vacuum nozzle atomising system consists of
the following components:
•
vacuum nozzle Type VN
•
control unit Type CU-1
•
pilot valve Type PV
•
vacuum valve Type VV8
•
air and water filter
•
hygrostat
•
fittings, T-pieces and plastic hoses
