Prior to Starting

!CAUTION

Provisions should be made to have the instruction manual readily available to the operator and maintenance personnel. If the manual becomes illegible or lost, have it replaced immediately. The instruction manual should be read periodically to prevent a serious accident.

Before starting the unit, review Sections II and III of this manual and be certain that all installation requirements have been met and that the purpose and use of each of the controls and all warnings are thoroughly understood. Adhere to the following checklist before placing the compressor into operation:

•Remove all loose items and tools from around the compressor.

•Check fluid level in the gearbox.

•Check the fan and fan mounting for tightness.

•Manually rotate the compressor through enough revolutions to be certain there is no mechanical interference.

•Ensure that all pressure relief valves are in place and properly sized.

•Make sure all panels and guards are in place and securely mounted.

•Check fuses, circuit breakers and thermal overloads for proper size.

•After all the above conditions have been satisfied close the main power disconnect switch, jog the starter switch button to check the rotation of the compressor

•Install the coupling guard.

•Check the fan rotation (air should push outward through the enclosure).

•Check inlet and discharge water piping for proper connections, adequate supply and open drain.

NOTE

When freezing temperatures are expected before the next start-up, drain all cooling water as follows:

•Drain inlet and outlet water lines at the cabinet connections.

•Remove drain plugs from fluid cooler and stage one water jacket tube.

•Inject compressed air at 15-20 psig into the system to remove the remaining coolant.

Starting the Compressor

•Secure all enclosure panels on compressor.

•Select the mode of operation and start the compressor.

•Watch for excessive vibration, unusual noises, or air/ fluid leaks. If anything unusual develops, stop the compressor immediately and correct the condition.

•Control settings have been adjusted at the factory; however, they should be checked during start-up and readjusted, if necessary. Some applications may require a slightly different setting than those provided by the factory (never increase pressure settings beyond factory specifications). Refer to Section VII - Service Adjustments.

•Observe compressor operation closely for the first hour of operation and frequently for the next seven hours. Stop and correct any noted problems.

NOTE

If the unit fails to start consult Section IX - Troubleshooting. Do not adjust the unload pressure more than 5 PSIG beyond the full load pressure rating of the machine.

Stopping the Compressor - Normal Operation

Press the shutdown button on the keypad below the main display.

NOTE

It is always a good practice to close the service valve when the compressor is not being used. It will prevent the system’s air pressure from leaking back into the compressor if the check valve leaks or fails.
