Daikin Air Handler CAH030GDCC

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

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.

Sign off on the coil maintenance

Filters removed from inside the unit

Wire clips rotated to release filters

Clean filters fully seated in the frame

Pressure drop for installed filters

Typical filter pressure drop for clean filters at rated air flow

Final pressure drop for front loaded filters

Prefilters removed to check the pressure drop of the final filters

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

CAUTION: Sharp fin edges are a potential injury hazard. Avoid contact with them

To obtain maximum performance, the coil must be clean

Check once a year under normal operating conditions and, if dirty, brush or vacuum clean.

Use a chemical coil cleaner on multiple row coils

Read and follow the chemical cleaner's instructions as some cleaners may contain harsh chemicals

Take care not to damage fins while cleaning.
