Startup

2.0STARTUP

Before beginning startup, make certain that unit was installed according to the instructions in the installation manual, SL-11962. Verify that the fan shipping bolt has been removed, the check valve has been installed (on air cooled units), and that the scroll compressor is rotating in the proper direc- tion. All exterior panels must be in place with the front panel open.

Locate the startup form supplied with your unit documents. Complete the form during startup and mail it to Liebert when startup is completed. Contact your Liebert supplier if you have any questions or problems during unit installation, startup or operation.

! WARNING

Risk of electric shock. Can cause injury or death.

Potentially lethal voltages exist within this equipment during operation. Observe all cautions and warnings on unit and in this manual.

The Liebert iCOM microprocessor does not isolate power from the unit, even in the “Unit Off” mode. The only way to ensure that there is NO voltage inside the unit is to install and open a remote disconnect switch. Refer to unit electrical schematic.

2.1Startup Procedure

___ 1. Disconnect all power to the environmental control unit.

___ 2. Tighten all electrical wiring connections that may have loosened during shipping (on electric panel and at all major components, such as compressor, reheats, humidifier and motor).Retighten according to values listed on component by component manufacturer.

___ 3. Remove all line voltage fuses except the main fan fuses at the far right of the electric panel and the Control Voltage fuses at the far left of the electric panel. For units supplied with circuit breakers, open the circuit breakers instead of removing fuses.

___ 4. Turn on power and check line voltage on main unit disconnect switch. Line voltage must be within 10% of nameplate voltage.

___ 5. Turn On main unit disconnect switch and check secondary voltage at transformer T1. Voltage at T1 must be 24 VAC ±2.5 VAC (check at TB1-1 and TB1-8). T1 voltage must not exceed 28 VAC. Change primary tap if necessary.

___ 6. Push the On button. Blower will start.

___ 7. If you do not want your unit to operate at factory default settings, set temperature and humidity setpoints, alarms, and other control functions. Refer to 3.0 - Operation with iCOM Control or 5.0 - Operation.

___ 8. Stop the unit by depressing the On/Off button on the front display. Turn Off main unit disconnect and main breaker.

___ 9. Replace all fuses (or reset circuit breakers) that were removed in Step 3.

___ 10. Restore power to unit; turn On the main unit disconnect switch.

___ 11. Push the On button—putting the unit into operation.

___ 12. Check the current draw on all line voltage components and match with serial tag.

___ 13. Verify that the scroll compressor is rotating in the proper direction.

NOTICE

Risk of improper scroll compressor installation. Could cause poor performance and compressor damage.

Three-phase power must be connected to the unit line voltage terminals in the proper sequence so that the scroll compressor rotates in the proper direction. Rotation in the wrong direction will result in poor performance and compressor damage. Use a phase sequence and motor rotation sensor to ensure that the three-phase power is correctly connected and that the compressor is rotating properly.
