After the installation is complete, adjust the angle of the sensor unit.
(1) Loosen the four screws (


(2) Remove the six screws (

, 3 each on top and bottom), and remove the heater assembly
cover (

).
(3) Loosen the four bolts (

) with the supplied wrench.
(4) Place the supplied mirror (


with a flat head screwdriver or other suitable tool until the air bubble in the level (

in between the two red lines. Turning the adjustment screw counterclockwise brings the
bubble position toward the front of the instrument.
(5) Tighten the four bolts (
