How do I change the water filter?
Steam Humidification System 69-2286EF—07 19
• Changing the reverse osmosis filter cartridges. If the reverse osmosis filter is used in your
installation, you will need to replace two filter cartridges once every humidification season. Notice that the
reverse osmosis filter option has more components than the in-line filter and includes a separate drain line.
This option provides better filtration and prevents harder water from flowing into your Steam Humidifier.
Remove filters #1, #2, and #3, in this order .
Reconnect filters in this order:
• Empty water from the #3 filter and reconnect to the
RO System. (Do not replace.)
• Connect a new #2 filter.
• Connect a new #1 filter.
