Installation, de-installation, servicing and repair
Steam injection humidifier parts on which maintenance or repair
work is to be done must be disconnected from voltage and the
steam supply shut off. Installation of any addition al p arts is
allowed only after written permission from the manufacturer.
Electrical
Only qualified electricians may carry o ut electrical work on the
unit.
Remove voltage from any compone nts being worked on. If the
energy supply is malfunctioning switch off the unit immediately .
After electrical wo rk or repair is carried out all safety ele ments
must be tested for proper functioning.
Attention: Use only steam with a minimum pressure of 0,5 bar
and a maximum pressure of 4 bar at the entry point of the steam
injection humidifier.
Attention: Steam pipes are hot and care must be taken accord-
ingly.
Attention: use only steam without chemical additives.
Attention: S team su pply must be dimension ed so that the
steam velocity does not exceed 25 m/s.
Attention: The control valves a re not stop valves. They have
been optimised to control the necessary steam supply. They are
metal to metal sealed according to IEC 534-4 Class
IV
and can,
therefore, show a leakage of 0.01 % when supplied. We recom-
mend the use of a sto p valve in order to en sure that the steam
supply is completely shut off.
Attention: There may be impurities in the steam supply. In order
to prevent valve da mage there must be a filter installed with a
pore diameter of <0.16 mm.
Attention: In o rder to maint ain a contin uous and const ant
humidification t he hu midity sensors sho uld not b e fit ted in the
supply duct.
2.2 Disposal after de-installation
