include the proof of purchase date in your correspondence. If you need to return a unit or component, call the

802 Storing the UPS
If you store the UPS, keep the temperature in the UPS location between -15° C and 55° C (5° F and 131° F).
The batteries in the UPS must be recharged every 90-120 days. Recharge the batteries more often if you
store the unit at temperatures above 35° C (95° F) to obtain maximum battery life. To recharge the
batteries, connect the UPS to AC input power for 10 hours.
The warranty of this product will be affected if the UPS is not stored properly.
803 Maintenance
Your Best 610 UPS requires little or no maintenance. Occasionally, you should inspect the input and
output connections for signs of damage and make repairs if necessary.
If you need to clean the unit, first remove all power to the unit by switching it off and unplugging it (or
disconnecting the AC input source).
If the unit is operating in an unusually dusty or dirty area, carefully vacuum any dust from the input vents and
from the ventilation holes.
