Daikin Air Handler CAH030GDCC

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

Motor bearings and ball bearings lubricated

Choose the type of lubricant used

Enter the amount of lubricant used

Motor run for five minutes after lubrication

Sign off on the motor bearings lubrication

Belt tension slacked off if belts have been installed

Capscrews E loosened but not removed

Pitch diameter adjusted by opening or closing the movable flanges by half or full turns

Setscrews D and capscrews E tightened

Belt tension readjusted if belts have been installed, or belts installed and tension adjusted if not previously installed

All keys are in place and all setscrews and all capscrews are tight before starting the drive

Warning: Moving belt and fan can cause severe personal injury or death. Always ensure safety measures are in place.

Is the belt tension at the lowest tension at which the belt does not slip under peak load conditions?

Measure the force applied to the belt tension checker

Does the measured force match the required values?

Are the belts free from foreign material that can cause slippage?

Is the V-drive inspected on a periodic basis?

Is the belt tension adjusted if the belt is slipping?

Check all moving parts for wear

Check bearing collar, sheave, and wheel hub setscrews, sheave capscrews, and bearing hold-down bolts for tightness

Annually check and snug all electrical connections

Inspect for signs of water damage such as corrosion and repair if necessary

Check ground conductor and connection integrity and correct if needed

CAUTION: For safety, stop rotating equipment before lubrication

Did you add one half of the recommended amount of lubricant?

Start bearing, and run for a few minutes

Did you stop the bearing and add the second half of the recommended amount of lubricant?

A temperature rise, sometimes 30°F (1°C) after lubrication is normal

CAUTION: For best results, specific applications should be monitored regularly and lubrication intervals and amounts adjusted accordingly

Compatibility of grease is critical. Lubricatable bearings are supplied with grease fittings or zerks for ease of lubrication with hand or automatic grease guns. Always wipe the fitting and grease nozzle clean
