Personal Injury and Unit Damage Hazard

Fans and Fan Motors

Periodically check the condition of fan wheels and housings and fan

motor shaft bearings. Contact your dealer for the required annual maintenance.

Heat ExchanRer

To ensure dependable and efficient heating operation, the heat ex-

changer should be checked by a qualified maintenance person be- fore each heating season, and cleaned when necessary. This check-

out should not be attempted by anyone not having the required

expertise and equipment to properly do the job. Contact your dealer for the required periodic maintenance.

Indoor and Outdoor Coils

Cleaning of the coils should only be done by qualified service per- sonnel. Contact your dealer for the required annual maintenance.

Condensate Drain

The drain pan and condensate drain line should be checked and cleaned at the same time the cooling coils are checked by your deal- er.

Compressor

All compressors are factory shipped with a normal charge of the cor- rect type of refrigeration grade oil. A compressor should rarely re- quire additional oil.

Condenser (Outdoor) Fan

PERSONAL INJURY AND UNIT DAMAGE HAZARD

Failure to follow this warning could result in personal injury, death or property damage.

Do not insert sticks, screwdrivers, or any other objects into

revolving fan blades.

The fan must be kept free of all obstructions to ensure proper cool- ing. Contact your dealer for any required service.

Electrical Controls and Wirin_

Electrical controls are difficult to check without proper instrumenta-

tion. If there are any discrepancies in the operating cycle, contact your local dealer and request service.

Refrigerant Circuit

The refrigerant circuit is difficult to check for leaks without the prop-

er equipment. If inadequate cooling is suspected, contact your local dealer for service.

EXPLOSION AND ENVIRONMENTAL HAZARD

Failure to follow this warning could result in personal injury, death or property damage.

System under pressure. Relieve pressure and recover all refrigerant before system repair or final unit disposal. Use all

service ports and open all flow-control devices, including solenoid valves.

Unit Panels

After performing any maintenance or service on the unit, be sure all panels are fastened securely in place to prevent rain from entering unit cabinet and to prevent disruption of the correct unit airflow pat- tern.

Combustion Area and Vent System

For proper and safe operation, the furnace needs air for combustion

and ventilation. The air openings, on the furnace, the air openings to the area in which the furnace is installed, and the spacing around the furnace must not be blocked or obstructed.

The combustion area and vent system should be inspected visually

before each heating season. The normal accumulation of dirt, soot, rust, and scale can result in loss of efficiency and improper perform-

ance if allowed to build up. This inspection should be done by a trained service person.

FIRE, EXPLOSION HAZARD

Failure to follow this warning could result in personal injury, death and/or property damage.

If your unit makes an especially loud noise when the main burners are ignited, shut down the heating section and call your dealer.

BURN HAZARD

Failure to follow this caution may result in personal injury.

Components in heating section may be hot after unit has been started up. When observing flame, be careful not to get close to or touch heating components.

Regular Dealer Maintenance

In addition to the type of routine maintenance you might be willing to perform, your unit should be inspected regularly by a properly

trained service technician. An inspection (preferably each year, but at least every other year) should include the following:

1, Inspection of all flue product passages-including the burn-

ers, heat exchanger, and flue collector box, Mare sure the burner flames are blue in color and in proper adjustment. Re- fer to Fig. 8 for burner flame.

2. Inspection of all combustion-and ventilation-air passages and openings.

3. Closeinspectionofallgaspipesleadingtoandinsideofyour unit.

4.Inspection and, if required, cleaning of the outdoor and indoor coils.

5.Inspection and, if required, cleaning of the indoor coil con- densate drain pan.
