ATTENTION CODES
A1: Power head is not attached to the base. If you detach the power head
while the humidier is running, or if power head is not properly attached
to the base, the humidier will power off. Control panel LED’s ash and
display A1. Power button illuminates orange until power head is attached and
aligned with the base correctly and Element is powered back on.
CH: When the water tank runs out of water, a "CH" auto rell notication code
will ash for 5 seconds on the control panel every 15 seconds until the tank
is relled. Once water is added "CH" code will clear after a short period of
time. Unit does not need to be powered on as it will automatically resume
operation once water is added. Note: When tank is out of water, there will be
no visible steam.
CL: When the heat element has accumulated mineral scale and cleaning is
needed, a "CL" cleaning notication code will ash for 5 seconds on the
control panel every 15 seconds until cleaned. Once clean, "CL" code will
clear. The unit will continue running and will not turn off due to "CL" code.
Note: If the unit is used for an extended period of time after being notied of
"CL" code but still has not been cleaned, a decrease in visible steam plume
may be noticeable. This indicates diminished performance.
