The ADU is a safe, durable unit. Troxler cannot anticipate
every example of improper or unauthorized use of this unit
that may lead to malfunction or accident. Thus, if a particular
use is not specifically mentioned in this manual as authorized,
then consult Troxler about the alternate use. Otherwise, it is
assumed that the use is unauthorized and improper.
Safety Warnings
Always follow the safety warnings in this manual and the
safety procedures of your laboratory/company. Troxler
recommends the following safety information:
The AC connection for 100 – 132 (or 180 – 240) VAC,
50/60 Hz output power to the vacuum pump provides
the same voltage as that supplied to the ADU. To
prevent equipment damage, ensure that the vacuum
pump is rated for the proper voltage.
For electrical safety reasons, the AC power cable that
provides power from the ADU to the vacuum pump
should not exceed 3 m (10 ft.).
The ADU is designed as a bench-top laboratory test
instrument. Place the unit on a level, sturdy surface.
The ambient temperature should be between 10 and
50C (50 and 122F), and the relative humidity should
be less than 80%.
Only personnel who are familiar with the proper
operation of the ADU should operate the device.
Always unplug the ADU before performing service or
maintenance.
Only Troxler service representatives should perform
service on the ADU when disassembly is required.

In nt tr ro od du uc ct ti io on n t to o t th he e A AD DU U
The Automatic Drying Unit is a fully-automated device that
dries specimens placed in the chamber. It is intended for use
with compacted asphalt core samples as well as loose asphalt
mix and loose aggregate (with supplied sample bag). In
comparison to the current methods used for drying these
samples, the ADU is very fast and convenient.
Currently, compacted asphalt cores are allowed to dry in front
of a fan for several hours. The cores are weighed, then dried
further and weighed again to be sure that they are truly dry.
These cores cannot typically be analyzed for density until the
day following their removal from the pavement. The ADU fully
automates and significantly shortens this process, allowing
the laboratory technician to be free to complete other tasks.
The ADU uses a simple process of vacuuming the air from the
sample chamber, thus pulling the water from the sample. A
heating element is placed outside the chamber to allow the
sample to remain close to ambient temperature. The water
that is evacuated from the chamber is transferred to a
reservoir and trapped there so that the pump is protected
from damage.
The pump draws the air and water from the sample and
chamber until the pressure reaches a level predetermined as a
“dry calibration” value. At this point the sample is considered
dry and the process is complete. The sample can then be
further analyzed for the properties that need to be
determined.

The ADU includes the electrical and mechanical parts required
to dry asphalt specimens. Use Figure 1-1 to locate and
identify the following parts:
The power switch is located on the right side of the ADU.
The keypad and display provide the user interface.
The serial port enables the operator to download data to
a computer for saving or printing.
The chamber lid (part number 117410) seals the chamber.
The vacuum pump (not shown) removes moisture from
the specimen.
The vacuum pump power receptacle powers the vacuum
pump.
The Model 5151 Manual of Operation and Instruction (not
shown) provides the operating instructions for the ADU.
NOTE
Troxler provides the option to purchase the ADU
with or without a Busch 7 CFM heavy-duty pump
(part number 117209). If you choose to replace this
pump with an alternative, please ensure that it has
the same or similar specifications. Troxler also
recommends using high-quality vacuum oil with any
pump used (part number 117232).

WARNING
The ADU weighs approximately 50 lbs (22.7 kg)
and its weight is not distributed evenly. To
prevent personal injury, observe proper lifting
techniques when unpacking and installing the
unit. Troxler recommends that the ADU be lifted
by two people, with one person at each end.
Unpacking
Upon receiving the ADU from the factory, perform a complete
inspection and inventory as described below.
1
1. . Inspect the contents of the shipping case. If the shipping
case or any other part or accessory appears damaged,
notify the carrier and your Troxler representative
immediately.
2
2. . Open the carton and carefully remove the unit. Save all
packing material for reuse if the unit needs to be returned
to Troxler for service or repair.
3
3. . Check the shipping case for the items listed in the on page
1-6. If any part or accessory is missing, contact your
Troxler representative.
4
4. . Inspect the outside surfaces of the ADU and its
accessories for damage.

After unpacking and inspecting the ADU, select a suitable site
for installation. Apply the following criteria when selecting a
site:
The ADU has no special ventilation requirements.
Place the ADU on a level, sturdy work surface near a
vacuum pump.
The ADU requires a 100 – 132 (or 180 – 240) VAC,
50/60 Hz single phase input power.
For electrical safety reasons, the AC power cable that
provides power from the ADU to the vacuum pump
should not exceed 3 ft (10 m).

To begin using the ADU, follow the installation steps below:
1
1. . Following the site selection guidelines in the previous
section, set the ADU in the selected location.
2
2. . Using the 12 mm (1/2 in.) ID tubing and hose clamps
provided with the unit, connect the vacuum pump to the
vacuum fitting on the side of the unit.
3
3. . Remove the filler plug on the pump and add oil to the fill
line. Do not overfill! Replace the filler plug.
4
4. . Connect the vacuum pump’s AC power cord to the AC
power outlet on the left side of the ADU.
5
5. . Connect the ADU to a standard outlet.
CAUTION
The AC connection for 100 – 132 (or 180 – 240) VAC,
50/60 Hz output power to control a vacuum pump
provides the same voltage as that supplied to the ADU.
To prevent equipment damage, ensure that the
vacuum pump is rated for the proper voltage.
