Immediately call a qualified service technician to inspect the unit and to replace any part of the control system and gas control which has been under water. MAINTAINING YOUR UNIT All maintenance should be handled by skilled, experienced personnel. Your dealer can help you establish a standard procedure. For your safety, keep the area around the unit clear and free of combustible materials, gasoline and other flammable liquids and vapors. To assure proper functioning of the unit, the flow of combustion and ventilating air must not be obstructed from reaching the unit. Clearance of at least 3 ft on flue and condenser sides and 6 in. on all other sides is required. ROUTINE MAINTENANCE AND CARE FOR THE EQUIPMENT OWNER Before proceeding with those things you might want to maintain yourself, please carefully consider the following: A WARNING 1. TURN OFF GAS SUPPLY AND THEN ELECTRICAL POWER TO YOUR UNIT BEFORE SERVICING OR PERFORMING MAINTENANCE. 2. Do not turn off electrical power to this unit without first turning off the gas supply. 3. When removing access panels or performing maintenance functions inside your unit, be aware of sharp sheet metal parts and screws. Although special care has been taken to reduce sharp edges to a minimum, be extremely careful when handling parts or reaching into the unit. Air Filter(s) — Air filter(s) should be checked at least every 3 or 4 weeks and changed or cleaned whenever they become dirty. Table 1 indicates the correct filter size for your unit. See Fig. 4 for filter access door location. To replace or inspect filters: 1. On 48DJD,DJE units, lift open the filter access door and lift and pull the filter track until it falls toward you. On 48LJD,LJE units, remove screws on filter access panel and remove panel. Lift up filter track and pull track until it falls toward you. If the 48LJD,LJE unit has a field-installed accessory filter access door, follow instructions above for 48DJD,DJE units. 2. Remove the left filter by pulling outward from the track. 3. Slide the right filter over to the left and then remove. When installing filters, note the direction of airflow arrows on the filter frame. NOTE: It is recommended that filters be field installed outside of the unit on horizontal economizer/two-position damper applications. Otherwise, the economizer/two-position damper will have to be partially removed to access the filters. The area of the field-installed filters should be equal to the area of the factory-installed filters as shown in Table 1. If you have difficulty in locating your air filter, or if you have questions concerning proper filter maintenance, contact your dealer for instructions. When replacing your unit filters, always use the same size and type of filter that was originally supplied by the installer. Units with outdoor air capability have a cleanable filter for the outdoor air. This filter should be checked annually and cleaned as necessary with steam or hot water and a mild detergent. Do not use disposable filters in place of cleanable filters. A WARNING Never operate your unit without filters in place. Failure to heed this warning may result in damage to the blower motor and/or compressor. An accumulation of dust and lint on internal parts of your unit can cause loss of efficiency and, in some cases, fire.
