▪ Operation
The HF Charger Series has been designed to provide fully automatic recharging of most 12V, 14V or 16V maintenance
free, deep-cycle, AGM and gel-cell batteries. If possible, disconnect all loads from the battery by removing battery cables,
opening a disconnect switch, or switching loads o󰀨.
To charge your 12V, 14V or 16V battery:
1) With the charger’s power switch in the OFF position plug the charger into a grounded wall receptacle.
2) Connect the red positive (+) clip of the charger cables to the positive (+) terminal of the vehicle battery.
3) Connect the black negative (–) clip of the charger cables to a solid chassis ground. If this is not possible, connect
it to the negative (–) battery terminal.
4) Flip the power switch on the back panel to ON. The Power LED will illuminate red while the microprocessors
analyze the battery and after a short delay, the Charging LED Indicator on the front panel will illuminate orange,
beginning the three-stage charging sequence. *Note that the charger will automatically restart the charging sequence if the charge current
rises above a factory preset threshold.
9) When complete, the Charging LED Indicator will turn green, ip the power switch to OFF.
10) Remove the black negative (–) clip and the red positive (+) clip from the vehicle’s battery terminals.
