5.2 Inspection and Cleaning
Air circulation through the cabinet may cause dust to accumulate on internal components. Cleaning
should be done as necessary during electrical inspections.
Annual general system inspections, cleaning, and operation checks are recommended to ensure sys-
tem performance and long service life.
5.2.1 Inspection 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.
