INSTALLATION

Mounting the LU30 properly is critical to operation. If the LU30 is
installed such that it is recessed in a fitting or flange, follow the crite-
ria listed below. For an I.D. less than 3", do not recess the LU30 more
than 1" for best results.

Factory Settings:

The LU30 sensor is preset at the factory. When powering up the sen-
sor the first time, the factory settings will be active. If at any time in
you need to return to these settings, remove power from the sensor
and wait 10 seconds. Press the [Set] and [Menu] buttons simultane-
ously while powering up the sensor.

Changing Display Units:

The LU30 comes preset to measure in inches. To change the unit to
display centimeters, remove power to the unit and wait 10 seconds.
Press [

s] and [Set] simultaneously while powering up the sensor. The

LU30 will now read in centimeters. To return to inches, remove
power and wait 10 seconds. Press [

t] and [Set] simultaneously while

powering up the sensor.

Maximum Application Range

The maximum range of Echotouch™ is 24.5 feet at 110 dB. Yet a
number of factors can reduce the overall quality of signal return and
shorten the accurate range of the transmitter. To determine the maxi-
mum application range of the product, follow the signal return for-
mula against the echo attenuation graph below.

Warning

Always install the 2” Viton gasket with the LU30-50__. The G
threaded version of the Echotouch will not seal unless the gasket
is installed properly.

When installing the LU30, never tighten the transmitter from the
body. Always use the wrench flat located above the threads.
