Changing the Water Filter
Replace the polyphosphate water filter at least once every humidification season.
Turn the water supply off at the saddle valve or T-fitting
and manual shutoff valve.
Press down on the filter collar ring and pull out the 1/4-
inch water line from each side of the filter.
Insert the 1/4-inch line into a new filter. Apply a modest
pull to ensure a tight fit.
Be sure to install the new filter correctly. The arrows on
the filter must point to TrueSTEAM in the direction of
the water flow.
Secure the new filter in place with clamps or ties to
support weight. Turn water supply on and check for
leaks.
If the optional reverse osmosis filter is used instead of
the polyphosphate filter, there are two filter cartridges
to be replaced. Replace the cartridges once every
humidification season or when the Cleaning Required
or Service light starts blinking due to water fill/drain
issues.
See “Reverse Osmosis Filter” on page 23.
