2. When removing access panels or performing mainte-

A. Air Filters  
Air filter(s) should be checked at least every 3 or 4 weeks and  
changed or cleaned whenever it becomes dirty. Dirty filters  
produce excessive stress on the blower motor and can cause the  
motor to overheat and shut down. Table 1 indicates the correct  
filter size for your unit. Refer to Fig. 2 to access the filter(s).  
ROUTINE MAINTENANCE  
All routine maintenance should be handled by skilled, experienced  
personnel. Your dealer can help you establish a standard proce-  
dure.  
For your safety, keep the unit area clear and free of combustible  
materials, gasoline, and other flammable liquids and vapors.  
To replace or inspect filter(s) (or accessory filter rack when  
supplied):  
To assure proper functioning of the unit, flow of condenser air  
must not be obstructed from reaching the unit. Clearance of at least  
48 in. is required from top of unit and on sides except the power  
entry side (42 in. clearance) and the duct side (12 in. minimum  
clearance).  
1. Remove the filter access panel using a 5/16-in. nut driver.  
2. Remove the filter(s) by pulling the filter(s) out of the unit.  
If the filter(s) is dirty, clean or replace with new one.  
When installing the new filter(s), note the direction of the airflow  
arrows on the filter frame.  
If you have difficulty in locating your air filter(s), or if you have  
questions concerning proper filter maintenance, contact your  
dealer for instructions. When replacing filters, always use the same  
size and type of filter that was supplied originally by the installer.
