Maintenance of Your Humidifier
Your humidifier, as all appliances, requires periodic cleaning and maintenance to ensure efficient
and safe operation. The necessity to clean your humidifier is substantially the result of impurities
coming in through your water supply, which feeds the humidifier. Other household dust,
containing biological and microbial contaminants, finds its way into the air handling system and
ultimately, the humidifier. The humidifier is not the source of these impurities.
To enjoy the benefits of a properly humidified environment, periodic cleaning is necessary to
control both water and household impurities. Bacteria or fungi may appear on the water
surface, the sides, or bottom of your humidifier. A crusty deposit or scale may also appear and is
composed of minerals that have settled out of the water.
Annual cleaning is required for the efficient and safe operation of this humidifier. However,
more frequent maintenance and cleaning may be required in areas of poor water quality.
During the first heating season, check for scale buildup on a monthly basis and establish the
proper cleaning schedule. Failure to do so can result in reduced efficiency and/or water damage
to house and property. If frequent cleaning of the humidifier is required, a sediment filter should
be installed upstream of the conical mesh filter to reduce the frequency of cleaning. Water
softeners can be used to improve the quality of the supply water, however, deionized water is
corrosive and can reduce the operating life of your unit.
To Inspect and Clean the Conical Mesh Water Filter
1. Turn OFF the water supply at the saddle valve by turning the valve handle clockwise.
2. Disconnect the water line from the INLET fitting of the solenoid valve using two (2)
wrenches, one for the compression nut and one on the INLET fitting.
3. Remove the conical mesh filter from inside the inlet fitting using a small nail or paper clip.
NOTE: Be careful not to puncture the filter.
4. Clean or replace the filter as needed.
5. Replace the filter and reconnect the water line to the INLET fitting reversing the directions
in Step 2.
6. Turn the water back ON at the saddle valve.
To Inspect and Clean the Fluid Restrictor
1. Turn OFF the water supply at the saddle valve by turning the valve handle clockwise.
2. Disconnect the water line from the OUTLET fitting of the solenoid valve using two (2)
wrenches, one for the compression nut and one on the OUTLET fitting.
3. Locate the fluid restrictor, inside the end of the water line, and inspect it for sediment
clogging and accumulation. Clean or replace fluid restrictor as needed.
NOTE: Do NOT attempt to enlarge the hole size in the restrictor.
4. Reconnect the water line to the OUTLET fitting reversing the directions in Step 2.
5. Turn the water back ON at the saddle valve.
