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 cooling. Contact your dealer for any required service.

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 pattern.

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