Adjusting Angle
Perform this procedure to adjust the position of the ventilator. Use your hand
to unscrew the tilt adjustment knob, and then lock it in place from above, and held in the
inclined position by tightening the knob. For negative tilt, use the negative tilt bracket. This
provides tilt up/down adjustment, from 0 to + 34 degrees.
For confined space rescue operations, you can place the ventilator directly on top of a
manhole. Tilt range from -90 to +90 degrees. Note that those positions can direct airflow
downward or upward

Operational Modes
AC Operation
• Input Voltage. 90-250VAC, 50/60Hz
• The ventilator is capable of operating seamlessly in countries that supply electricity at
either 120V AC/60 Hz or 240V AC/50 Hz without manual adjustments by the user.
• Operation out of these limits can damage electrical components and will void the
warranty.

2. Status LED Light will automatically turn green, displaying the status “Ventilator is
connected on AC Power Supply”.
3. Start the ventilator by using the Speed Control knob to the desired speed.
Note: You can keep the batteries on their location without charging the battery.
Battery Indicator Lights will turn off because there is no battery charging
when ventilator is running on AC.

the battery Indicator Lights will redisplay battery charge level of each battery pack detected.
The ventilator will begin charging the battery packs after 60 minutes of idle time.
