YOUR FURNACE’S FILTER -

WHAT IT DOES

The filter in your furnace takes the lint and dust out of the air that passes through it. This keeps dirt particles from getting into the moving parts of the furnace, where they could cause serious damage. It also keeps the dirt from circulating through your home.

As the filter continues to collect these particles, it becomes clogged and no longer allows enough air to circulate through the furnace. If this happens, the heat exchangers and blower motor could overheat; a potentially dangerous situation. It is very important to keep the air filter clean! Never operate your fur- nace without a suitable air filter.

WARNING: When replacing fil- ters DO NOT use a type with excessively high pressure drop. Some high efficiency filters avail- able will cause the furnace to operate improperly and could re- sult in a safety hazard.

FREQUENCY OF CHECKING FILTERS

Clean your furnace’s filter at least every three months. If you need to replace a filter, check the filter chart to be sure you install the right size and type of filter for your furnace.

If your home is new, you should check the filter every week for the first four weeks after you begin to use the fur- nace, and then at least every three weeks after that, especially if the system runs constantly.

NOTE: Some installations may have more than one filter.

LOCATING/REMOVING FILTERS

UPFLOW FURNACES

Most upflow furnaces have their filters located on the side or bottom of the furnace in a filter frame.

If your furnace has this type return filter frame, remove the door by pulling on it. Slide the filter out of its channel. To replace after cleaning, slide filter into place and snap the door on the end of the filter rack.

Some installations may have filters lo- cated in the blower compartment. Check with the installer for your filter location.

NOTE: The spring-loaded safety cutoff switch, mounted under the blower deck will automatically cut off the electrical power supply to the furnace when the blower panel is removed.

To remove bottom mounted filter(s) on all furnaces, push the looped end of the filter retainer to the side and then lift up. Reverse the procedure to reinstall filters.

DOWNFLOW FURNACES

The filters in your downflow furnace are located in the plenum or ductwork above the furnace.To check the filters, turn off the electrical supply to the furnace.
