PRIOR TO FIRST USE
1. Operate on AC voltage, 85-264V, 50/60 Hz 1Φ, for charging and discharging.
2. The unit is suitable for use on Ground Fault protected circuits.
3. Should the provided AC connector be unsuitable, replace with desired
connector containing a grounding circuit. Check continuity from ground
terminal to motor shell.
4. Place batteries into holders and connect to IP66 connectors, Fully charge
prior to first use.
5. This fan is for emergency service use. Charge fully between runs. Create a
charging protocol.
6. To charge, turn the speed control fully to the left (OFF) and then connect
to AC outlet. Indicator lights will illuminate, and then go off. When charging
commences, indicator lights will show state of charge. Charging should
complete in 3-4 hours, with the indicator lights turning green.
7. For DC operation with AC disconnected, hold the wake button until
indicator lights come on showing battery state. Advance speed control.
8. For AC operation, advance speed control.

AC Operation
The EX50Li is a multi-purpose 18"/46cm ventilator powered by battery(s) or
85-264v single phase AC. The flexible frame configuration allows for PPV, Smoke
Ejector or ducted blower use in both normal, horizontal and hanging positions.
The fan can be tilted from 0-36° within the frame in PPV mode.
The motor, motor controller and batteries are water-resistant, IP66 rated.
The motor is a variable-speed BLDC motor controlled by a microprocessor
integrated with
a power supply, dual battery chargers and an LED light driver.
The EX50Li will run with one or two 40v 6Ah Li-ion battery packs. Each pack
yields about 23 min of operation at full power. Extended operation is achieved
by reducing speed. The batteries may be swapped during operation.
AC voltage can be applied while running on batteries and the ventilator will auto-
switch to AC power. Conversely, the AC power can be removed and the unit will
auto-switch to battery power, if sufficient charge remains.
The integrated battery chargers will charge one or two fully discharged battery
packs in 4 hours or less.
LED scene lights are integrated into the fan shroud and have a high-low-off
switch.
Hold to change.
The integrated controller is EMI-protected to prevent interference with radio
communication.
A simple Control Panel on the top of controller controls all functions.
1. When AC is disconnected and Speed control is off, the controller and
battery(s) will enter a sleep mode to conserve the battery power after 60
minutes of no activity.
2. To wake, push and briefly hold Wake button on control panel. Indicator
lights will show battery status. The unit will return to sleep mode if not
used within 10 minutes.
3. If Speed control is not in off position, return to off, and then advance
as desired.
4. Blower will run on one or two battery packs. Two packs are used
simultaneously and discharge evenly. Runtime is doubled with two packs.
Indicator lights show battery charge state as in table. Indicator lights
will turn red, then flash red as end of charge approaches. Batteries will
disconnect at the end of their charge and blower will stop.
5. Battery(s) may be swapped for charged batteries at any time.
6. Reduce run speed to minimum required to increase runtime.
Unit Description
1. Connect blower to AC source.
2. Indicator lights will come on and will show battery charge.
3. Indicator lights will be solid green while running on AC, not showing battery
charge.
4. When fan is stopped, indicator lights will show battery charge. The fan will
begin charging after 15 min of idle time.
5. Speed control must be off or turned to off before unit will run; a safety
precaution to prevent unwanted fan start.
6. Advance the Speed control as desired.
7. Batteries do not charge while fan is on.
