To order replacement foam seals, email your order requirements, including
the relevant part code(s) detailed below to: [email protected]
¢AEP-SPARC-SEAL1 (1” pipe)
¢AEP-SPARC-SEAL2 (2” pipe)
¢AEP-SPARC-SEAL3 (3” pipe)
¢AEP-SPARC-SEAL4 (4” pipe)

Ensure an O-ring seal is present on the clamping
face of the water box.
1
Select the water box to suit the pipe size to be
tested, check the foam seal is in good working
condition and that it is mounted securely to
the water box.
Select the appropriate probe and attach to the
water box, securing into place with the corner
screws.
Fit screws through the saddle, the probe and
into the water box securing all components
together.
1.21.1
Position the probe mounting saddle over the
centre of the probe.
Fit the central screw post of the water box
through the buggy and attach the large thumb
screw to the post on top of the buggy.

1. Water box assembly

Check all the cables and tubing are connected
to the scanner and that they are suitably
grouped and tethered to prevent accidental
damage.
2
Adjust the probe height by winding the central
screw of the water box in as far as possible
using the large thumb screw. Ensure the water
box is fully retracted in the buggy.
Adjust the separation of both sets of wheels
to the correct pipe size to be tested using the
graticules marked on the scanner.
Fine tune the wheel separation if necessary so
that all four wheels are centred to run on a
radial line.
2.22.1
Attach the magnetic wheels on the buggy to
the pipe.
Wind the water box towards the pipe until all
of the seal is in contact and concentric to the
pipe.

X = 33 Steps / mm
Reduce the ow rate of the water supply until
it is just sufcient to maintain the water box
coupling. If a good seal is achieved then it
should be possible to stop the feed completely.
3
Turn on the water supply to ood the water
box and use the ultrasonic display to ne tune
the adjustment of the probe height until it is
concentric (at B-scan on perfectly round pipe).
Check the encoder is seated correctly and
rotates with scanner movement, recording
positional data. Adjust the spring rate via the
encoder mounting thumb screw if required.
Start the acquisition unit collecting data,
then pull the scanner along the pipe using the
Sp-Arc handles.
3.23.1
Set the encoder resolution to 33 steps/mm
(quadrature). Move the scanner to the start
position and set the position on the acquisition
unit to zero. X = 0mm

4

Holding the two handles, twist the scanner to
break the magnetic attachment and pull the
Sp-Arc away from the pipe.
4
Lower the probe height until the water box is
fully retracted in the buggy using the large thumb
screw.
Check that the low friction layer of the seal is
in good working order. If the water box leaks
excessively or the seal looks worn then it is
time to replace it.
Replace with a new seal from the supplied
items. The seal should comprise; plastic
holder, compliant foam layer and low-friction
wear resistant layer.
4.24.1
Undo the screws on either side of the seal to
remove the worn seal unit.
