Operation
1. The D5i-M unit will be activated when power is supplied to the unit and the
green
LED light is
illuminated, indicating the ‘On’ position.
2. The D5i-M unit is self-balancing and does not require any type of adjustment.
3. The benefit of the D5i-M unit is achieved only when the supply fan is running. Therefore, to achieve
improved air quality, interlock the D5i-M unit to run when the supply fan is powered.

1. The D5i-M unit is connected to power, the supply fan is running and that the
green
