SECTION 2: OPERATIONS
2.5 Electric Motor Driven Units
The safety instructions applicable to this product are contained in Appendix A.2. They must be read,
understood and complied with prior to operating the product.
2.5.1
Pre-start Checks
1. Ensure that all scheduled maintenance is completed.
2. Check compressor oil level. Refer to Section 3.1.
2.5.2
Start-up Procedure
1. Complete all Pre-start checks.
2. Verify that all connections downstream of the compressor are secure.
3. Open the condensate drain valves to relieve any remaining pressure.
4. Close the condensate drain valves.
5. Apply electric power to the unit.
6. Immediately check the direction of motor rotation (CCW when viewed from the flywheel side}.
7. If rotation is incorrect, remove electrical power and refer to the Troubleshooting Section.
2.5.3
Post Start Procedures
1. Allow the compressor to build up pressure. Monitor the pressure gauge.
2. Listen to the unit as it operates. If excessive knocking or vibrations are observed shut down the unit.
3. Allow the compressor to reach full pressure.
4. Attach regulating/filling device to the fill hose assembly. Use only devices approved for the intended
service.
5. Adjust the fill pressure regulator to the proper fill pressure.
2.5.4
Shutdown Procedures
1. Verify all bottle valves and fill valves are closed.
2. Remove electrical power.
3. After the compressor drive stops, open the condensate drain valves to relieve any remaining pressure
and drain any moisture from the intermediate separators and the oil and water separator.
4. Close the condensate valves.
5. If the compressor is to remain idle for six months or longer, refer to the Appendix titled, Long Term
Storage for preservation instructions.
CAUTION
Minimum bend radius for the fill hose is 1½ inches. Less than this will cause damage to or failure
of the fill hose. Place the bottle so that the bend radius of the hose is greater than 1½ inches.
