Emerson SERIES 600T Manuel D’Utilisation

The Liebert FS maintenance schedule consists of actions listed in Table 11.

Set up a maintenance log to record scheduled checks and any abnormal conditions.
The log should have space for all metered parameter indications including phase readings, alarm 

messages, mode of operation, air filter replacement date and observation notes.
A periodic walk-through inspection of the Liebert FS room is advised to check for visible and audible 

indications of problems. Log the inspection, metered parameter indications and any discrepancies.

Any maintenance on the system should be delayed by at least 10 minutes after system is shut 

down to be certain all electronics have discharged. Use appropriate safety precautions to 

ensure unit is disconnected and de-energized.

Unless specified otherwise, ONLY a Liebert-certified service technician should perform all 

maintenance work. Failure to use a Liebert technician for maintenance actions, unless 

specifically noted, may void your warranty.
