5.
Electrical
- Check the wiring diagrams furnished with the unit to be sure it is properly wired. See
Figure 4-11 thru Figure 4-12, page 40 thru page 43, for general wiring diagrams and Section 2, for
installation instructions.
6.
Grounding
- Equipment must be properly grounded according to Table 250-95 of the National
Electrical Code.
Failure to properly ground the compressor package could result in controller
malfunction.
7.
Rotation
- Check for correct motor rotation using “JOG MODE.” Compressor drive shaft rotation
must be counterclockwise standing facing the compressor coupling. Check the rotation on the fan
motors. Vent fan motors should blow into the package. Air cooled cooling fan should blow through
the cooler.
Operation with incorrect motor rotation can damage equipment and cause oil
eruption from the compressor inlet. When checking motor rotation, induce
minimum rotation (less than one revolution if possible). Never allow motor to
reach full speed.
The compressor unit’s direction of rotation must be checked every time the
compressor is reconnected to the power supply.
8.
System Pressure
- Set the controls to the desired load pressure. DO NOT EXCEED THE
MAXIMUM OPERATING PRESSURE ON THE COMPRESSOR NAMEPLATE. See Controller
Manual 13-17-600 for procedure.
Operation at excessive discharge air pressure can cause personal injury or
damage to equipment. Do not adjust the full discharge air pressure above the
maximum stamped on the unit nameplate.
9.
Operating Mode
- Refer to Section 4 for detailed information on the control system.
10.
Enclosure
- Check for damaged panels or doors. Check all screws and latches for tightness. Be
sure doors are closed and latched.
