PERFORMING ROUTINE MAINTENANCE NOTE: The qualified installer or agency must use only factory- authorized replacement parts, kits, and accessories when modifying this product. Installing and servicing of heating equipment can be hazardous due to gas and electrical components. Only trained and qualified personnel should install, repair, or service heating equipment. Untrained personnel can perform basic maintenance functions such as cleaning and replacing air filters. All other operations must be performed by trained and qualified service agency personnel. Observe safety precautions in this manual, on tags, and on labels attached to the furnace and other safety precautions that may apply. With proper maintenance and care, your furnace will operate economically and dependably. Instructions for basic maintenance are found on this and the following pages. However, before beginning maintenance, follow these safety precautions: WARNING! Turn off electrical power supply to your furnace before removing the main furnace door to service or perform maintenance. Failure to follow this warning could result in personal injury/death or property damage. CAUTION! Although special care has been taken to minimize sharp edges, be extremely careful when handling parts or reaching into the furnace. Failure to follow this caution woud result in minor personal injury. FILTERING OUT TROUBLE CAUTION! Never operate your furnace without the air filter in place. Doing so may damage the furnace blower motor. An accumulation of dust and lint on internal parts of your furnace can cause a loss of efficiency and would cause minor property or product damage. A dirty air filter will cause a loss of airflow in your duct system. When excessive loss of airflow occurs, the furnace may cycle on its safety controls. If this condition is left unattended, the furnace will eventually lock out. It is recommended that the furnace air filter be checked every 3 or 4 weeks and cleaned if necessary. If installed with factory-specified disposable media filter, check or replace filter before each heating and cooling season. Replace media filter at least once a year. The air filter is normally located in the blower compartment (See Fig. 3 or 4.) or in the factory-supplied filter cabinet attached to the side or bottom of the furnace casing. If air filter has been installed in another location, contact your dealer for instructions. To inspect, clean, and/or replace the air filter(s), follow these steps: 1. Turn off electrical supply to furnace. (See Fig. 20.) 2. Remove door/access panel • AIR FILTER(S) LOCATED IN BLOWER COMPARTMENT a. Remove main furnace door. (See Fig. 23.) b. Remove blower access panel. (See Fig. 24.) NOTE: It will be necessary to remove 2 screws • AIR FILTER LOCATED IN FILTER CABINET a. Remove filter cabinet door (See Fig. 25 and 26.) NOTE: It will be necessary to remove 1 thumbscrew 3. Remove air filter from furnace. • AIR FILTER LOCATED IN BLOWER COMPARTMENT BOTTOM: a. Slide filter retainer sideways until it is free of latch. (See Fig. 27.) b. Slide air filter out of furnace. (See Fig. 28.) • AIR FILTER(S) LOCATED IN BLOWER COMPARTMENT SIDE: a. Remove filter retainer from latch. (See Fig. 29.) b. Gently remove air filter and carefully turn the dirty side up (if dirty) to avoid spilling dirt from the filter. (See Fig. 30.) • AIR FILTER LOCATED IN FILTER CABINET: a. Slide air filter out of furnace. Keep dirty side up (if dirty) to avoid spilling dirt. (See Fig. 31 and 32.) 4. Inspect the filter. If torn, replace it.
