General Information

SAE-1062

(Duct)

WARNING

Do not use in an explosive or hazardous
environment, with combustible or flammable gases,
as a safety or emergency stop device, or in any other
application where failure of the product could result
in personal injury.

CAUTION

Read these instructions carefully before installing
and commissioning the CO2 detector. Failure to do
so may result in product damage.

Strong shock or vibration may affect the calibration
of the SAE-1011/1012/1062. Be careful to not
drop the detector while installing or calibrating
it. Take electrostatic discharge precautions during
installation. Do not exceed the device ratings.

NOTE: The SAE-1011/1012/1062 models replace

the older SAE-1001/1002/1051 models.

For the installation and conguration
information on the older models, see the
SAE-1001/1002/1051 installation guide (717­019-37).

Mounting

SAE-1011/1012 Space Mount

Install the unit at least ve feet above the oor of
the area to be controlled. Do not install near doors,
windows, supply air diusers, or other known air
disturbances. Avoid areas where the detector is
exposed to vibrations or rapid temperature changes.

1. Remove the Phillips-head screw on the boom
edge of the cover. (See Illustration 1.)

2. The cover is hooked to the base/backplate at the
top edge and must be removed from the boom
edge rst. Tip the cover away from the base and
set it aside. (If necessary, use a small screwdriver
to carefully pry each boom corner.)

NOTE: The IEI-1011 LCD display module (used

with the SAE-1001/1051 models for
conguration) does not apply to the SAE­1011/1012/1062 models since they each have
permanent LCD displays. The display of
the SAE-1011, however, is hidden when its
cover is closed.

NOTE: See the SAE-1011/1012/1062 data sheet for

specications and additional information.

3. To access the mounting holes, CAREFULLY

remove the circuit board from the base by gently
pressing the enclosure base to unsnap the latch
near the boom edge and lifting the circuit board
from the backplate.

CAUTION

Follow proper electrostatic discharge procedures
when handling the circuit board and be careful to
not touch the sensors.

4. Set the circuit board aside until the base is
mounted on the wall.

5. Aach the universal backplate/base directly to
a standard electrical box using two screws. (See
Illustration 2.)

6. After the base is secured, pull the wires through
the wiring hole in the center of the circuit board
and then reinstall the board in the enclosure base.
Ensure the circuit board is snapped into the base
securely and correctly.

7. After wiring, conguring, and testing the unit,
reinstall the cover and screw.

SAE-1062 Duct Mount

1. Cut a 1-1/4" hole in the duct for the air sampling
tube.

2. Insert the probe into the hole and mark the
enclosure mounting holes. (See Illustration 4.)

3. Remove the unit and drill the four mounting
holes. (Clean all drilled holes of debris before
mounting the device.)

4. Mount the enclosure to the duct with four sheet
metal screws such that the duct air ow is paral­lel with the vent holes in the probe (i.e., air ows
directly into the probe holes). To prevent air
leaks, ensure the gasket is compressed around
the probe between the device enclosure and the
air duct.

5. Open the cover by removing the two screws and
releasing the latch. (See Illustration 3.)

6. Aach conduit to the conduit opening.

7. Feed wires through the conduit opening, and
connect to the terminals according to the wiring
instructions.

8. After wiring, plug the conduit with plumber’s
puy, painter’s puy, caulk, or other sealant to
prevent air inltration from aecting accuracy of
the duct readings.

9. Check that the rubber gasket is placed correctly
between the enclosure and cover.

The duct type sensor installs on the outside of a
return air duct with the sampling tube inserted into
the duct.

Choose a mounting location in a straight section of
a return air duct. Mount at least 5 feet (or 7.5 duct
diameters) from corners or other items that may
cause disturbances in the air ow. Avoid areas prone
to vibration or rapid temperature changes.

10. After wiring, conguring, and testing the unit,
close and latch the cover. Secure it with the two
screws.
