Annual general system inspections, cleaning, and operation checks are recommended to ensure sys- tem performance and long service life.

! WARNING

Only qualified service personnel should perform maintenance on the Liebert FPC system. All voltage sources to the unit must be disconnected before inspecting or cleaning within the cabinet.

5.2.1Inspection Schedule

•It is difficult to establish a schedule for periodic cleanings because conditions vary from site to site. Inspections after the first 24 hours, 30 days and 6 months of operation should help determine a pattern for the inspection schedule.

•Electrical connections and component mountings should be inspected after the first 24 hours, 30 days, and 6 months of operation. Inspections should be conducted annually thereafter.

•Ventilation openings and grilles should be inspected and cleaned every 6 months to one year.

•A complete inspection and operational checkout should be performed annually. This is best done by performing the inspection and start-up procedure as detailed in 3.0 - Inspection and Star- tup Checklist.

•LGS offers a complete range of preventive maintenance services. These include thorough equip- ment performance checks and calibration of electronics. Contact Liebert Global Services in the United States by calling 1-800-LIEBERT for details.
