Verify that installation is complete by using the Checklist for Complete Installation.
1. Disconnect all power to the InteleCool2 unit.
2. Adjust remote control to prevent compressor, heat and fan operation.
3. Turn on main breaker and check line voltage on main unit disconnect switch. Line voltage must

be within ± 10 volts of nameplate voltage.

4. Turn ON main unit disconnect switch and check secondary voltage at transformer T1. Voltage at

T1 must be 24 VAC ±2.5V.

5. From the remote control, verify proper operation in all modes.
6. Make sure all blowers, fans, and the scroll compressor are rotating in the correct direction.
7. Check the current draw on all line voltage components and compare with unit nameplate.
8. Check adjustment of the optional outside air damper for the desired balance between the flow of

room air and outdoor air. Use a gauge or non-polluting airflow indicator.

NOTE
If the unit is supplied with crankcase heaters, Liebert recommends that the high voltage be

applied between four and six hours before start-up.
