Warning: This maintenance check requires qualified personnel!

Drain pans in any air conditioning unit may have some moisture

Algae, etc., can grow due to airborne spores and bacteria

Periodic cleaning is necessary to prevent this buildup from plugging the drain and causing the drain pan to overflow

Also, keep the drain pans clean to prevent the spread of disease

Cleaning should be performed by qualified personnel

Dirt and lint can clog the condensate drain, especially with dirty filters. Inspect twice a year to help avoid overflow

Fan assembly removed and replaced?

CAUTION: Bearing overheating potential. Can damage the equipment. Do not over lubricate bearings. Use only a high grade mineral grease with a 200°F safe operating temperature.

NOTE: Direct-Drive Class Il fans that are supplied with TECO motors have double shielded bearings on frame sizes 140T-280T. These bearings are pre-packed with a long life grease and are not regreaseable. Larger frame size TECO motors are regreaseable and follow the same lubrication recommendations as all other motors
