IMPORTANT SAFETY INFORMATION
Classifications
Danger: To Prevent Serious Injury or Death
Warnings in this classification indicate danger that may result in serious injury or death if
not observed.
Caution: To Prevent Damage to the Product
Warnings in this classification indicate risks of damage to the product that may void the
product warranty and/or calibration.
Description of Symbols
ESD Caution: To Prevent Damage to the Product
Warnings in this classification indicate risks of damage to the product that may void the
product warranty and/or calibration. Internal components are static sensitive and are not
user serviceable. Opening the cases by a non-authorized service center and/or in a non-
ESD safe environment may cause damage not covered by the manufacturer’s warranty.
Important: Mandatory Action Required
The specific action is given near this symbol.
FCC Compliance Statement
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC rules. These limits are designed
to provide reasonable protection against harmful interference. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not
occur in a particular situation.

IMPORTANT SAFETY INFORMATION (continued)
EU – Declaration of Conformity
Kanomax-USA declares that the product for this manual complies with the
essential requirements and other relevant provisions of Directive 1999/5/
EC. A copy of the Declaration of conformity is available on request.
RoHS Statement
Concerning EU-Directive 2011/65/EU (RoHS 2), to the best of our
knowledge, based on supplier provided information, all Kanomax-USA
Instrument brand products, are not intentionally manufactured or
formulated with the following substances: Lead, mercury, cadmium, hexavalent
chromium, polybrominated biphenyls (PBB), polybrominated diphenyl
ethers (PBDE). Minimal levels established in the 2005 RoHS Directive still
apply under Article 4(2), Annex II: 0.1% by weight in homogenous
materials for lead, mercury, hexavalent chromium, polybrominated
biphenyls and polybrominated diphenyl ethers; 0.01% by weight in
homogenous materials for cadmium. Please be advised that we do not
analyze for these substances.
WEEE – Waste Electrical and Electronic Equipment - 2002/96/EC
Kanomax-USA asks that allour products tobe recycled at the end oftheir
current use, to comply with local waste requirements. Kanomax-USA supports
local Waste Electrical andElectronic Equipment (WEEE) directives where
they are inoperation. That means that WEEE may not be disposed as
unsorted municipal waste but istobe collected separately. Kanomax-USA
consumer products are therefore labeledwith a crossed-out “wheelie-bin”
symbol which you can see above. Further, allour products bear anyother
appropriate symbols for their respective region. WEEE may contain
hazardous substances which may negatively affect the environment and
human health when disposed of through normal channels. Kanomax-USA is
committed toreduce the negative environmental and human health effects of
WEEE.

DANGER
Never touch the vane assembly blades and/or thermal sensors.
The vane assembly blades may contain sharp edges which may cause minor
cuts. The assembly contains precision bearings which are sensitive and the
blades are finely adjusted to specific pitches. Touching this assembly or its parts
may cause damage which can affect its operation and the calibration.
NOTE: If the vane assembly head or probe head requires cleaning we
recommend a fine mist of isopropyl alcohol and a fine long-haired brush or send
the unit in or servicing.
Do not touch the circuit board when 120/220VAC is or has been
applied. Only connect 120/220VAC wires to the unit with power
disconnected. Double-check to make sure the wires are in the correct
terminals before applying power.
Power may still be present after voltage has been removed via storage in the
capacitors. Only authorized repairs can be accomplished after proper
discharging of the circuits.
CAUTION
When measuring, ensure that the direction arrow is facing the
direction of airflow.
The arrow indicates the direction of airflow for the data provided on the calibration
certificate. It is meant to allow for uniform and consistent readings as per the provided
data. The probe will operate in the opposite direction but the data may be different.
The transmitter case is designed to protect against dust and powerful
water jet penetration (IP 66), when properly closed. 2
Do not over-tighten the cover screws, only secure snugly. Over-tightening may cause
cover warping and damage. Only insert round, appropriate sized cables into the Liquid
Tight Cord Grips. Use of non-round, double cables/wires, or too small cabling may
reduce the IP rating and cause damage.

CAUTION (continued)
Do not use or leave the instrument in a high temperature, high humidity,
high speed airflows or dusty environments for prolonged periods.
The instrument may not function properly out of the specified operating conditions and/or
have a greatly reduced operating life span.
Do not subject the instrument or the probe to strong impacts.
Dropping the instrument or the probe may cause damage or malfunction to the instrument
and may change the calibration data. We recommend sending it in immediately to be
checked.
Never disassemble, modify or repair the product.
Failure to observe the above may cause damage to the instrument or the probe. It may
also void the manufacturer’s warranty and calibration certificate.
Do not pick up or carry the instrument by the cable.
It may cause a malfunction or damage to the wiring of the cable.
Do not wipe the instrument with a volatile solvent.
Use neutral solvents and simple cleaners to clean the instrument with a soft cloth.
Regularly check the head of the probe for contamination.
Impurities (such as dust) on the blades and/or thermal sensor may affect the
accuracy of the instrument.
NOTE: If the vane assembly head or probe head requires cleaning we
recommend a fine mist of isopropyl alcohol and a fine long-haired brush or send
the unit in or servicing.

INTRODUCTION
The AT400 and TAT420 air velocity transmitters supply
accurate air velocity and (TAT420) temperature data from a
building or process airflow on a continuous basis to a computer,
chart recorder, printer, and meter or control circuit.
Every instrument has terminals for both DC and AC power, and
0-1V, 0-5V and 4-20mA outputs. The outputs are concurrent and
can accept multiple wires (depending on the gauge used).
The heavy, all metal (except for the electronics pod) air probes
can be used for airstreams that have a wide range of humidity,
temperature and contaminants without compromising accuracy.
