SECTION 6—CLEANING
NOTE: For proper positioning, the air inlet of the humidifier elbow
at the back opening of the water reservoir must be completely round.
6. Pull and twist the humidifier elbow so that the air outlet
points straight to the top of the water reservoir and the two
notches on the thin flange align with the two tabs inside
the water reservoir. Refer to Detail "B" of FIGURE 6.5.
To prevent leaks, ensure that the thin flange is completely
inside the water reservoir and that the air outlet points
straight to the top of the water reservoir.
7. The humidifier elbow should look as shown in
FIGURE 6.4 when installed.
