Bearing Housing Oil Level Check

Check the oil level in the oil cup at shutdown.

Is the oil level in the oil cup adequate?

Fill to the proper level with SAE 30 (ISO 100) weight oil if necessary.

Operate the system until the oil is warm.

Refill with SAE 30 (ISO 100) weight oil.

Ensure mechanical equipment is inoperable during maintenance

Ensure bearings are adequately lubricated before returning motor to service at the start of a new operating season.

Is the blowdown system discharging water continuously during operation?

Enter the current concentration level of dissolved solids in the water.

Enter the current blowdown rate (percent of total water flow rate).

Verify the concentration levels are within acceptable range (2-4 concentrations)

Is the water treatment company maintaining a relatively constant level of concentrations?

Are water treatment chemicals being added outside the cold water basin?

Drain the entire system including cooling tower, system piping, and heat exchangers

Describe any necessary repairs made

Apply protective coating to all metal parts
