a. High: The fan will spin up to its maximum speed. This is the recommended setting for optimal performance.
b. Low: The fan will spin up to a designated speed (below max). If there is a significant load on the charger, it may limit its maximum output current in
order to maintain a safe internal temperature.
c. Off: Forces the Fan to stay off. If there is significant load on the charger, it may limit its maximum output current to maintain a safe internal temperature.

AC current is approximately 15% of the DC current at 120V line voltage and 7% of the DC current at 240V line voltage.
NOTE: The designated maximum amperage is the total available amperage to be supplied among all 3 outputs. Selecting an amperage less than the maximum
could result in under charging of batteries.
9. Press the OK button once desired max amperage output is reached.

Warning: Incorrect Absorb and Float voltages could reduce the life of your batteries. Contact your battery manufacturer for recommended Absorb and Float voltages.
CAUTION
Selecting a battery type different from the connected batteries could limit the life of the batteries and damage them.
