In most cases, the conductivity levels given in Section "Direc-
tions for Use" of these instructions can be considered normal.
Individual parameter setting of the control may be necessary.
In extreme cases, water pretreatment may be necessary (soft-
ening by dilution to approx. 4 - 8 °dH; decarbonization/partial
desalination to achieve target reductions in carbonate hard-
ness). HygroMatik would be pleased to refer you to companies
specializing in water treatment systems.
9.2 Access Electrical Enclosure
» Remove cover from humidifier (B) and lift display plate
(A) of guiding.
» Turn display plate (please see sketch) and hang up dis-
play plate by using the „front guiding“.
» The basic PCB (C) is now accessable.
Danger, Hazardous Voltage: Make sure the unit is switched off
before installing or removing the display plate.
