TD 8 PREVENTIVE MAINTENANCE Every Gamatronic UPS contains technologically advanced electronic systems These electronic systems are sensitive to environmental conditions It is important that the operating and storage environments of the UPS be clean and dust free free of dampness and excess humidity The system s batteries provide back up power to the UPS when needed An environmental temperature of 20 C 68 F is ideal for the batteries Significantly higher temperatures shorten the batteries lifespan The UPS and its batteries both require periodic preventive maintenance inspections At the least these inspections should include a visual inspection of the UPS and its batteries and the tightening of any screws and bolts that have over time become loosened The owner of the UPS is responsible for ensuring that the preventive maintenance inspections take place This is done by contacting Gamatronic s service department and arranging a mutually convenient time for a technician to perform the inspection It is important that the UPS owner continue to arrange regular preventive maintenance inspections even after the expiration of the initial warrantee period Gamatronic bears no liability for damage caused to the UPS due to improper maintenance by third parties in particular after the expiration of the warrantee or service agreement It is the responsibility of the UPS owner to uphold his responsibilities according to the warrantee o
