4.7. Application limits
DuringtheplanningandinstallationofUltraSonichumidiers,takecaretoensurethatallmaterialsthat
come into contact with demineralized water are resistant to it. See table at bottom of page for the most
important materials.
Application limits
Water quality <80μS/cm,upto150μS/cmforbriefperiods
Supply voltage to control unit 230 V ± 10%
Voltagetoultrasonichumidier 48 V ± 10%
Water pressure 0.5barto6barupstreamofultrasonichumidier
Water temperature 8°C to 40°C
Air humidity ≤90%RH
*Forindividualoperatinghours,e.g.duringstart-uporduringthedeliverytimeofnewltercartridges.
No longer than 5% of operating hours in total. Also see "4.9. Water treatment" on page 22.
CAUTION
Reducing conductivity.
Depending on the planned application, it may make sense to further reduce conductivity.
This must be done by the plant operator.
Note
CAUTION
High dust content.
Iftheairhasanunusuallyhighdustcontent(e.g.siliconpowderinprintingpresses),the
airmustbeltered,becausedepositsofdustonthewaterreducethecapacityofthehumidier.
Theairlterisnotincludedwithdelivery,andneedstobeprovidedbytheplantoperator.
Note
CAUTION
Quality of drinking water.
The conductivity of the treated water may vary depending on the quality of the available drinking
water.
Note
CAUTION
Room temperature below 0°C.
Thehumidiermustnotbeusediftheroomtemperaturedropsbelow0°C.
●
Drain the water tank of the units.
NOTICE
CAUTION
Resistant materials.
Theconnectionbetweenthedemineralizationsystemandthehumidiermustconsistofamaterialthat
is resistant to demineralized water.
