FOR SAFETY: Before leaving or servicing
machine, stop on level surface, turn off
machine, and remove key.
The ec-H2O system is equipped with a water

potential scaling.
The cartridge is required to be replaced when it
reaches its maximum water usage or expiration

Depending on machine usage a new cartridge can
last anywhere from 12 to 24 months.
All cartridges are labeled with a manufacture date.
The shelf-life of an un-installed cartridge is one
year from manufacture date. For new cartridge
replacement, the ec-H2O module timer must be
reset. See ec-H2O WATER CONDITIONING
CARTRIDGE REPLACEMENT.
The control panel will signal the following code
when it’s time to replace the cartridge. The ec-H2O
icon will begin to blink blue and red. See SERVICE
INDICATOR CODES for further details.
ATTENTION: During fi rst time use and after
replacing the water conditioning cartridge, the
ec-H2O system will automatically override the
selected solution fl ow rate for up to 75 minutes.
