START-UP CHECKLIST

WARNING

Never assume a compressor is safe to work on just because it is not operating. It could

restart at any time. Follow all safety precautions and guidelines outlined in this manual.

Go hrough this checklist you start the compressor for the first ime.before

WARNING

Failure to perform the steps outlined in the start-up checklist, may result in mechanical

failure, property damage, serious personal injury or even death.

Review Installation parameters in the prior section.

Double-check hese items:

- Distance from walls at least 30”.

- Properly mounted.

- Flexible coupler between compressor and shop.

- No toxic, volatile, or corrosive fumes in the area.

- Correct wire size, fuses, or circuit breakers.

Check the oil level in the pump and add if necessary.

Check that all pressure relief valves are in place and operational.

Check that the air filter is in place and securely mounted.

Remove all loose objects and tools around the compressor installation.

Open the service valve and any other shut off valves in the air system.

On three phase compressors, “bump” the motor to verify that you have the correct rotation (CCW facing the shaft).

Reverse if necessary.

BREAK-IN PROCEDURES

After completing the START-UP CHECKLIST you are ready to run the compressor. Always go through this procedure

before restar ing your unit, if you have moved it to a new location or have had service on the pump or motor.

Start the compressor and check for excessive noise or vibration. If there is any condition that appears unsafe, stop the

compressor immediately and fix the problem. If the compressor is running normally, allow the unit to pump for ten

minutes before closing the service valve and allowing the compressor to pump up and shut off. Check the system for

leaks.

Pay close attention to the compressor for the first hour of use. It is not necessary to run the compressor “un-loaded” to

seat the rings.

3. During he first full day of running the compressor you should note how many times an hour the compressor is starting.

During an “average” hour you should check what percent of those 60 minutes the compressor is running. If the

compressor starts more than eight times or runs for more than 75 percent of an average hour,you need more air.
