1. Unscrew the two screws holding the Return Air
Sensor detector plate. (See Fig. 23.) Save the screws.
2. Remove the Return Air Sensor and its detector plate.
3. Rotate the detector plate so the sensor is facing out-
wards and the sampling tube connection is on the bot-
tom. (See Fig. 24.)
4. Screw the sensor and detector plate into its operating
position using screws from Step 1. Make sure the
sampling tube connection is on the bottom and the ex-
haust tube is on the top. (See Fig. 23.)
5. Connect the flexible tube on the sampling inlet to the
sampling tube on the basepan.
6. For units with an economizer, the sampling tube is in-
tegrated into the economizer housing but the connec-
tion of the flexible tubing to the sampling tube is the
same.
