Preparation of
Aspiration Box for Mounting
Note: The mounting location for
the Telaire Model 1508
Aspiration Box should
be in the return air duct.
The ideal location for
mounting is one that will
allow easy access for
modifying or ca
the sensor.
Prepare the Aspiration Box for
mounting as follows:
1. Remove the box cover. Ensure the three holes located on the inlet
tube face the duct air flow as shown.
2. If the three inlet holes are facing in the wrong direction, simply turn
the tube 180° while making sure the box is in the correct orientation.

Installation of
Aspiration Box
1. Using the template
provided, mark the four
mounting holes and one
1-¼” hole (for inlet
tubing) on the duct.
2. On the duct, drill or
punch the four mounting
holes and one 1-¼” air
inlet hole.
3. Mount the Aspiration
Box to the duct using four sheet metal screws. Verify the three holes
on the inlet tube are facing the airflow.
4. Once the Aspiration Box is secure, pass the wiring through the open
conduit hole and the large opening on the sensor mounting bracket.
5. Using the four mounting screws (provided), secure the sensor
mounting bracket to the four stand-off posts in the aspiration box.
6. During wire installation, use caution while routing the wires through
the box. Strip the wire insulation approximately 1/8” and ensure the
exposed wire is free of loose strands.
7. Next, make the necessary wire
connections by following the
pin designations on the terminal
block label. Insert the wires into
the terminal block and seat the
wire insulation flush against the
terminal blocks. When wiring is
complete, check for any wiring
that may be touching adjacent
wires or terminal blocks.
8. For proper operation, it is
important to maintain an airtight
seal. Any opening should be
tightly sealed with caulk or putty.
3. Secure the inlet tube by tightening the large screw located in the
center of the mounting bracket.
4. Using a sharp, pointed object, punch through a conduit knockout.
Now the Aspiration Box is ready to be mounted on the duct.
