TROUBLESHOOTING
The following is not considered faulty operation:
If your water is very hard (containing abnormally high levels of minerals) the
·
humidifier may produce white dust. This is not a malfunction. The solution would be
to clean the filter more often or use softer water.
If you stand very close to the humidifier, you will hear the gurgling sound of water.
·
This is normal.
The machine operates very quietly but it is not completely silent. Noise levels less
·
than 35 db is considered normal.
WARNING!
If the above recommended solutions do not work, please contact Heaven Fresh technical
support at the telephone number for your region. Do not attempt to disassemble, repair
and reassemble the machine as it may void the warranty.
