Operating Procedure - BlowHard High Flow Jet Series Operation Manual

STEP 1 - BATTERY OPERATION:
•
The green battery LED should be solid green indicating a fully charged battery. Turn the
Power Knob to the right until it clicks ON. The red "BH" LED should turn on.
•
Your fan is variable speed. As the knob is turned clockwise the fan will turn on at low
speed and increase to high speed. Increasing or decreasing speed will directly impact
both performance and battery run time. Reducing power to low will extend run time to
hours.
•
NOTE: If the red "X" LED is solid red, the battery is BAD and must be replaced. The fan
can still be used in AC Mode if no damage has been done to the BMS. If the BMS is BAD
then the fan will not work at all. See TROUBLESHOOTING and call for service.
STEP 2 - AC OPERATION: Plug in the AC cord.
•
Charging: While the Power Knob is in OFF position: The BMS will automatically charge
the battery with available power from the AC power supply. See LED status chart for
sequence definitions.
•
Fan Operation: Turn the Power Knob clockwise to start the Fan. When the knob is turned
on charging will stop and redirect the AC power to run the fan. The red "BH" LED will turn
on when the knob is in the on position. Your fan is variable speed. As the knob is turned
clockwise the fan will turn on at low speed and increase to high speed. There is a "dead-
band" between the initial knob click and slow speed operation. With the knob in the dead-
band you can check LED power status without turning on the fan.
•
AC/Battery power switching: When operating your fan, your control system will sense and
automatically switch to AC power. If AC power is removed or lost, your control system will
automatically switch power back to battery if sufficient battery power is available. The
green battery LED will light up when running on battery.
Variable Speed Control:
•
Your fan is variable speed. As the knob is turned clockwise the fan will turn on at low
speed and increase to high speed. There is a "dead-band" between the initial knob click
and slow speed operation. With the knob in the dead-band you can check LED power
status without turning on the fan.
•
The fan can be started at maximum speed for PPV Operation by directly turning the Power
Knob fully clockwise. The Electronic Speed Controller (ESC) will ramp-up the fan to
maximum speed without causing any power surge.
•
To set the fan at speed other than maximum, the fan can be started at maximum speed,
and then dialed down, or start at minimum speed and quickly dialed up. The ESC will
control and prevent any power surge.
•
The minimum speed is factory preset to provide light ventilation, is useful for rehab
situations, and will significantly extend the battery usage for hours.
