Daikin Air Handler OAH034GDGM

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.

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.

Motor Bearings: Supply and return fans-Supply and return fan motors should have grease added after every 2000 hours of operation.

Using the following procedure, re-lubricate the bearings while the motor is warm, but not running.

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

NOTE: Specific greasing instructions are located on a tag attached to the motor. If special lubrication instructions are on the motor, they supersede all other instructions
