Note
To remove the IR sensor, if applicable, first power the unit off. Then
turn the two 1/4-turn fasteners on the top duct until the cover plate is
disengaged. Secured on the inside of the plate is a dummy sensor (Figure
5-6).
s
Grip the IR sensor and carefully pull it downward. Unscrew the cable
from IR sensor (Figure 5-13). Set the sensor aside. See Step 9 for the IR
sensor disinfection procedure. Connect the dummy sensor to the cable. Fit
the installed dummy sensor up into the previous sensor location.
When the power is turned on with the IR sensor removed, the display
toggles between “REMOVE HEPAs”, “REMOVE WATER”, and “PRESS
ENTER”. If “ENTER” is not pressed within 1 minute, the display toggles
between “POWER OFF” and “REPLACE IR”. When the unit is powered
back on with the IR sensor reinstalled, the display returns to “SYSTEM
OK”.
