INSTALLING NOTIFICATION PANEL WITHOUT AN ELECTRICAL BOX
1. Cut opening in sheetrock 1-1/4” wide by 2-1/4” tall, hold Notification panel terminal block mounting plate over opening and mark top
and bottom holes for wall anchors, (See Diagram H). Once marked, drill 3/16” holes for wall anchors and feed control cable through
opening, (See Diagram I).
2. Wire White, Red & Green wires from Dryer Booster cable to Notification Panel terminal block as shown, (See Diagram J)
3. Adhere Notification Panel label to coverplate and screw coverplate to electrical box with provided screws, (See Diagram G).Screw
Notification Panel terminal block holder to wall anchors with Green LED light on top, (See Diagram K). Adhere Notification Panel label
to coverplate and screw coverplate to electrical box with provided screws, (See Diagram L).

NOTIFICATION PANEL STATUS LIGHTS
Flashing Red and Green LED’s...Control calibrates to exhaust duct pressure drop when 1st plugged in
Slow Flashing Green LED............Idle state, No dryer operation sensed
Fast Flashing Green LED............Sensor is detecting dryer turning on or off
Steady Green LED.......................Dryer Booster Fan on
Flashing Red LED........................Blockage sensed or Dryer Booster Fan not operating
Steady Red LED..........................High temps detected, Dryer Booster Fan is shut off
LB2 CALIBRATION PROCEDURE
IMPORTANT: Make sure all of the following are performed before supplying power to the LB2.
• Confirm the LB2 and the entire duct system is completely installed and clear of lint. (Required for proper calibration.)
• Confirm the dryer is off and cool.
• Confirm all lint traps are empty of lint and reinstalled in their proper position.
• Confirm the Dryer is Empty of Clothing.
• Confirm the Door on the Dryer is Closed.
• Supply Power to the LB2 by plugging in the power cord or cycling the power circuit the LB2 is plugged into.
NOTE: Within 45 seconds of the LB2 Dryer Booster being supplied power, it will come on and run for up to 45 seconds. This is a cali-
bration period and will only happen when the LB2 is first powered. During this time the Red and Green LED’s on the Notification Panel
will both flash quickly in an alternating sequence. Once the calibration process is over, only the Green light will flash and at a much
slower pace.
Once the LB2 has been calibrated and just the Green light is flashing on for 1/2 second, off for 2 seconds, the clothes dryer can be used.
STATUS PANEL MODES
MONITOR MODE: (Green LED blinks 1/2 second on, 2 seconds off)
• When the dryer is not operating, the Green LED on the Notification Panel will blink for 1/2 second on, 2 seconds off. This is normal
operation and is an indication that the LB2 is ready for the Dryer to come on.
DRYER TRANSITION MODE: (Green LED flashes rapidly)
• When the dryer is turning on or off, the LB2 senses the change in pressure. During this time period, the Green LED will flash rapidly
1/2 second on, 1/2 second off.
PROPER VENTING MODE: (Green LED continuously on)
• When the LB2 is on, the Green LED will be continuously on.
PRESSURE FAULT MODE: (Red LED flashing)
• If at anytime during the calibration or operating cycle of the LB2 and the Dryer there is excessive pressure sensed, the Notification
Panel will flash the Red LED. The LB2 will continue to operate to try and clear the blockage. Stop the dryer immediately and have the
vent system inspected by someone qualified to do so. The power to the LB2 will need to be removed to clear the fault condition and
turn the LB2 motor off. The LB2 calibration cycle will need to be performed. (See LB2 Troubleshooting for complete details)
