Daikin Air Handler CAH004GVAM

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

Bearing should operate at temperature less than 200°F (94°C) and should not exceed 225 (107°C) for intermittent operation

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

Any good quality lithium or lithium complex base grease, using mineral oil, conforming to NLGI grade 2 consistency, and an oil viscosity of 455-1135 SUS at 100°F (100-200 cSt at 40°C) may be used for re-lubrication

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

WARNING: Personal Injury Hazard. Power supply can cause electrical shock. Always disconnect all power to unit before servicing

WARNING: UV-C exposure is harmful to the skin and eyes. Looking at an illuminated UV-C bulb can cause permanent blindness. UV-C skin exposure can cause cancer

WARNING: Fluorescent bulbs contain mercury, which can cause personal injury if breathed or ingested. Use appropriate protective gear to clean up broken bulbs

Verify the UV lights are off by using the view window

Disconnect power to the power receptacle before servicing

Verify the power is disconnected

Before opening the access panels, use the viewing window to make sure the UV lights are off

Before handling, allow bulbs to cool for 5 minutes

Grasp body of bulb firmly at each end

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.

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

Supply and return fans lubricated

Upper and lower grease plugs removed and cleaned

Clean grease added with a low pressure gun

Motor run for five minutes before replacing the plugs

Enter the amount of lubricant used

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
