CHARGER WILL NOT SWITCH INTO FLOAT MODE - If the charger will not switch into the float mode,
after 24 hours, then the battery is probably damaged and is not properly accepting the charge. Check
the open circuit voltage of the battery to see if it has any shorted cells - there should be about 2.15
V/cell for a properly charged battery (divide the battery voltage by two to get the number of cells). If
the battery voltage looks correct then you may be trying to charge a battery which has too large a ca-
pacity for the charger (see charging notes and tips).
MAINTENANCE INSTRUCTIONS
FUSE REPLACEMENT - The AC input module contains the main fuse and a spare fuse. Detach the
power cord. Use a flat head screwdriver or a coin to pry open the fuse drawer or holder. Replace the
blown fuse with the spare. You can use the old fuse to push out the spare fuse. Now is a good time to
install a new spare fuse. Replace fuses only with the same type (as indicated in this manual) and value
(as indicated on the charger).
CLEANING - Unplug the charger before attempting any cleaning. If it becomes necessary to clean the
enclosure, wipe the exterior of the enclosure with a damp cloth and a mild detergent. Do not use an
abrasive cleanser. Do not spray cleaners directly onto the charger or immerse unit in water.
