Battery Status Indicator Lights
On the control panel there are 2 sets of lights: on the top side of the battery lights indicate
the charge level in the battery attached to the left side of the ventilator, on the bottom side
of the battery lights indicate the charge level in the battery attached to the right side of the
ventilator.
If the battery is charging, the green indicator lights will horizontally scroll from left-to- right,
turning solid green when the battery is fully charged.
If the ventilator is running on battery power, the estimated remaining battery time is
shown.
If all the lights flash red, this indicates that the battery has failed and the battery must be
replaced.
Battery Pack Protection
• To protect itself from damage and extend its life, the battery pack's intelligent circuit
monitors current draw and temperature. In extreme situations, the battery pack will
turn OFF the ventilator if the current draw becomes too high.
• While a battery undergoes a charge cycle, its temperature rises. To prevent grid
corrosion and eventual battery failure, allow the battery to cool down in between
charging and discharging.

Make sure the battery pack is connected correctly to the ventilator, as described above in
“Connection of Battery Pack”.
• The next step is to leave the ventilator off. During charging, the battery indicator lights
will flash. The battery charge level can be recognized by the number of lights that are
constantly lit.
• When batteries and AC are connected, the batteries will begin charging after 60
minutes of idle time.
• Indicator lights will show charge state during charging. Charging should complete in
about 5 hours, with the Battery Status Indicator lights turning green. Should the Speed
Control be turned counterclockwise on during the charge, charging will stop, and the
ventilator will start. Charging will begin again after 60 minutes of idle time.
• After charging is complete, the chargers will maintain the battery(s) by keeping the
ventilator connected to AC.
• While charging, the battery status LED lights will strobe. The batteries will be
disconnected at the end of their charge automatically. At the end of charging, the
current power is displayed for 5 minutes and then the lights will be turned off.
