Installing the Dwyer 641 Air
Velocity Transmitter
The Dwyer 641 Air Velocity Transmitter (AVT) supplied with the EnergySmart
Dryer System should be installed within 8 or 12 in. {203.2 or 304.8 mm}
customer-supplied pipe using a 5/16
× 1/4 in. NPT compression fitting.
IMPORTANT:
The AVT should be installed in a straight piece of pipe, on the
return air side of the EnergySmart Dryer. Conair recommends locating the
probe toward the end of long straight section of pipe to allow the air flow
as much length as possible to straighten out before it comes in contact
with the probe. Placing the probe too close to a transition or bend will
influence air flow readings.
To install the AVT:
1
Determine the best location to install the AVTs following the
recommendations above.
2
If Conair’s hard piping kit was not purchased with your system, drill and
tap
customer-supplied 8 or 12 in. {203.2 or 304.8 mm} 2 ft. {0.6 m} long pipe
