Physical Installation
The AQSync Air Quality Monitoring Station is designed for outdoor environments and
meets NEMA 3 specifications for environmental protection. The polyester enclosure is
sealed to withstand rain and snow, and the enclosure is fitted with a weatherproof cable
gland for all cable connections.
B.2.1
Placement
Monitoring objectives will influence the choice of the location of the AQSync. In addition
to the air chemistry considerations, proper siting of the weather transmitter of the
AQSync must be considered. Locate the instrument away from obstructions, because
eddies from buildings, trees, or other structures influence the measurement. As a
general recommendation: If the height of the nearest obstruction is H, locate the
instrument at a distance of [10 × H] away from the obstruction, and at a height of [1.5 ×
H]. The weather transmitter user manual may be consulted for more information

B.2.2
Secure the AQSync
We recommend that the monitor be mounted on a post, wall, or specially built stand.
The back of the enclosure has three holes along each of the vertical sides that can be
used
for mounting. The holes are 1/4” in diameter and should be used with stainless
steel bolts and washers. The dimensional drawings are shown in Section B.3.
As shipped from the factory, two Unistrut mounting pieces are installed on the back of
the AQSync for use in handling the AQSync, and for possible use in mounting the
AQSync.
B.2.3
Orient the Wind Sensor
The wind sensor must be oriented to North:
•
Use a hex wrench to loosen the set screws.
•
Using your phone GPS to locate North, rotate the weather station as needed.
•
Retighten the set screws.
The weather station has a built-in compass that can be used to complete this step if a
smartphone is not available. Please consult the user manual linked here for more
information on using the compass:

In the AQSync as shipped from the factory, the compass is turned off. Contact us if you
wish to enable the compass.
