Initial Start-Up Procedures
CAUTION
Care must always be exercised when working with inlet air filter and lubricant lines to keep
foreign matter from entering the system. Failure to do so may result in equipment damage.
It is the user’s responsibility to correctly install and connect the unit. It is the responsibility of the person
performing the start-up to read and understand the contents of this Operations and Maintenance Manual
along with the Description of Operations / Display and Controls Manual.
If starting a unit that has been idle for several months, it is recommended that the connection above the
inlet valve be removed and compressor lubricant be poured into the unit through the intake. Add 4 U.S.
fluid ounces (118 mL) of lubricant for every 10 HP of rated motor for the unit.
Before the machine is started, check the following:
1. Machine is intact with no visible damage due to transit.
2. Remove shipping straps and orange/red brackets. Except on the KI/KIV-10.
3. Compressor unit is set flat on a firm surface and evenly supported on all mounting pads. Do not use
the wooden shipping pallet as a permanent mounting base.
4. Ample cooling air and ventilation is provided.
5. Verify proper lubricant level in sight tube.
6. Verify air end turns over by hand freely. This may require that the belt guard or coupling guard be
removed.
7. Verify V-belt tension and alignment on belt driven compressors.
8. Verify motor coupling alignment on direct driven compressors.
9. Verify unit is supplied with proper voltage and wiring connections are properly made.
10. Check all electrical connections for tightness.
11. Power up equipment to determine if phase protection fault is shown. Correct as necessary.
12. Momentarily start motor (jog) and observe rotation. The KI and KIV units are equipped with phase
protection which will not allow the unit to start. If the unit does not start when “jogged” check phase
monitor and phase protection. The unit must not be operated in reverse rotation for more than a few
rotations or serious damage can occur.
13. Verify correct fan rotation such that fan is pushing air through cooler. Cooling air should enter the
cabinet, pass through the fan, the cooler cores, and finally exit the compressor cabinet.
Once the above pre-start check list is complete it is permissible to start and operate the unit, by:
