OPERATING INSTRUCTIONS

Ensure that all installation and operating instructions and safety
precautions are understood and carefully followed by anyone
installing or using the charger. Follow the steps outlined in "Important
Safety Instructions" at the front of this manual.

Charge Rate Selection

After charger clamps are correctly connected, plug in the charger to a 120 volt AC
outlet and the charger will show a circulating pattern on the Digital Display, indicating
power has been applied. Select the proper charge current rate based on battery size.
Press the 4/10/20/40 AMP button and the charger will begin charging at 2 amps.
Pressing the 4/10/20/40 AMP button again will advance the charge rate to 10
amps, again to 20 amps, and again to 40 amps. Pressing the switch again will turn
OFF the charger output and the display will show "000."

Note:
The only time the selected charge rate does not display at the full selected rate
is when the battery is nearly full and charging at either step two or three. The
display will be showing a reduced charge rate. To return to 2A, press the
2/20/40 AMP button. When the battery is fully charged, the charging complete
and "FUL" is displayed on the Digital Display.
WARNING
If Digital Display shows "F02" and the Fault indicator lights, the
connection to the battery terminals is bad. Follow the steps outlined in
"Important Safety Instructions" at the front of this manual to
disconnect, clean battery terminals, then reconnect.
If Rev. Polarity indicator also lights, the Red (POSITIVE) and Black
(NEGATIVE) clamps are incorrectly connected to battery terminals.
Follow the steps outlined in "Important Safety Instructions" at the
front of this manual to disconnect, then reconnect in correct polarity.

Charging the Battery

1. Press Battery Type selector until desired battery type LED lights.
Note:
The default selection is "GEL" type battery.
2. Press 4/10/20/40 AMP button to begin charging at the 4 amp rate; the unit
sounds a beep and the charging current LED lights. The charger starts charging
at 4 amp rate automatically if 4/10/20/40 AMP button is not pressed within 3
minutes after applying AC power.
If the Display on the charger varies between "F03" and the amp rate, the battery
is sulfated and the charger is trying to give it some charge. If after approximately
2 hours the display just shows "F03", then the battery will not charge.
Charger occasionally sounds a beep and displays "0.0" during self-test or
charging stage changes.
3. Pressing the 4/10/20/40 AMP button again advances charging rate to 10
amps, pressing once more advances charging rate to 20 amps, and again to 40
amps. (Pressing the button again will turn OFF the charger output and the Display
will show "000".) This selection and actual battery charge rate are monitored by
the microprocessor, and the unit will stop charging if the selected rate is too fast
or too slow for battery size or condition.
As the battery nears full charge capacity, the unit's output will automatically drop
to a lower charge rate.
Pressing the 4/10/20/40 AMP button repeatedly advances to standby mode;
the unit sounds a beep, displays "000" and stops charging.
4. The battery charger displays the charge current. To view the battery voltage,
press BATTERY VOLTAGE button. The charger will sound a beep and display the
battery voltage for 3 seconds, then returns to displaying the charge current.
5. The display shows "FUL" when the battery is fully charged.
6. Follow the steps outlined in "Important Safety Instructions" at the front of this
manual to disconnect.
