Proper Maintenance

Reduces Energy Use

A clean filter saves money.

When the furnace circulates and filters the air in your home, dust and dirt particles build up on the filter. Excessive accumulation can block the airflow, forcing the unit to work harder to maintain desired temperatures.

And the harder your unit has to work, the more energy it uses. So you pay more any time your system is running with a dirty filter.

! CAUTION

Never operate your unit for either heating or cooling with filters removed.

Help ensure top efficiency by cleaning the filter once a month. If you have an upflow furnace, you can wash or change the filter once a month. Clean it twice a month during seasons when the unit runs more often.

Your furnace came from the factory with a cleanable filter. You can clean the filter with a vacuum, OR you can wash it with a household detergent. Good quality, high velocity filters may be used for replacements in upflow furnaces.

With the new patented filter rack on the upflow models, all cleaning or replacing of filters is quick and easy. Clean filters guarantee optimum performance of your system.

*NOTE - On 5 ton airflow models, if the airflow requirement exceeds 1800 CFM, these models will require filters on both sides; OR 1 side and the bottom; OR just the bottom.

Replacing your filter.

When replacing your furnace filters, use a high velocity type filter. On upflow furnaces, standard size 1" thick high velocity filters will fit into the patented filter rack which will automatically adjust in width to fit. Filters are available from your dealer.

How to remove your filter.

The upflow furnace blower door has a hinge at the bottom which allows the door to tilt forward for filter servicing or replacement without the door being removed. The furnace filter in the bottom or side configuration can be removed by simply turning the two latches on the blower door 1/4 turn and tilting the door forward.

Blower Door Hinge and Bottom Filter Rack Installation

The blower door may be removed if necessary by tilting the door outward 2 to 3 inches, then pulling up. The door will slide out of the hinge for removal. For replacement, simply insert the blower door bottom into the space between the furnace base front and the hinge, then tilt inward and latch.
