2 Installation and Security Hints
2.1 Setup of the Machine
The ground loor should withstand a pressure o 300 kg/m². Air cooled machines
should be installed in rooms not smaller then 200 m³.. This rooms should have a
good air exchange, to keep the room temperature below 28°C. Also or water
cooled machines , according to DIN EN 378-1 the room volume should be at
least 8 m³ , i with leak cooling gas comes into the atmosphere.
I the distance between the backside o the machine and the wall is below 50cm,
you should change the per orated cover to the ront side to ensure a ree
circulation or the air ( or air cooled machines)
Be sure that the machine stands horizontal. Please check this by a level at the
cooling bath. I necessary the machine may be setup by the our adjustable eet.
The horizontal deviation should be not higher then 1-2 mm/m.
This machine is constructed according to DIN EN 378-1class A. This means it is
allowed to run this machine in a room where people are sleeping, disabled
persons are working, or a lot o not instructed people are present. So there are no
special requirements in the training o the people working with, or nearby the
machine.
As cooling liquid a mix o 45 % tap water and 55 % glycol coolant is used. This
according to the European water protection standard level 0 . There are no special
requirements or environmental or water protection.
The re rigerant is
R507 (or R404A). This
re rigerants are ree o
FCKW. They are not
reducing the ozone
shield in the
atmosphere.
Compared with CO2
(GWP = 1,0) R507
has a high potential
or global warming
(GWP = 3800). This
act requires a care ul
handling with the
re rigerant. Service

at the cooling machine are allowed only or well trained and special educated
persons. Pleas contact our service center or urther questions.
The lubricant o the cooling machine has not be changed during the li etime o the
machine. The oil is classi ied at water dangerous class =1. There are no special
oil protection requirements necessary, because the machine automatically stopp i
there is a leakage in system.
The CDF/CIF-machine has a mains connection with a 3x32A/400V/50Hz CEE
connector. As circuit protection 3x32A are necessary.
The environmental conditions should be at 10 to 28 °C at maximum 65 % relative
humidity. I the humidity is higher there may be more condense water at some
machine parts. Below 10°C s special winter-controller should be ordered with the
machine. For temperatures over 28°C an additional water cooling is necessary.
Opening the lid o the cooling bath is only allowed when the bath temperature is
near the room temperature. We strongly recommend water-proo isolation
protection gloves. Contact to the cooling bath may cause reezing the skin,
ingers, or the hand.
2.2 Internet Connection
The CDF testing machine rom Schleibinger is equipped (option) with an internet
inter ace. So you may easy integrate the machine in your laboratory network or in
the world-wide-net. You can contact the CDF machine as easy as any other web-
site. Also you may use the telnet or FTP service.
The WEB server integrated in the CDF machine displays the the temperature data
as well as the actual temperature and some status in ormation.
To contact the CDF machine input the IP address o the CDF machine in your
web-browser so tware. For example :
http://192.168.1.40
The CDF machine need a ix IP address.
CDF-Freeze Thaw- Testing Machine page 5
2.2.1 Chiptool
To change this, start the so tware chiptool.exe delivered with the CDF machine on
your PC. This PC must be connected to the same network then the CDF machine.
Choose the menu point
Chip -Find in the chiptool
so tware. I everything is
well connected the CDF
machine will be
displayed. Then select
the machine and change
the IP address and the
network address
according to you local
network requirements.
Be sure that your PC and
the CDF machine are in
the same IP namespace, otherwise you may have to con igure also the Netmask.
You may also access the CDF machine with the chiptool File Trans er Protocol
"FTP Client" in the menu "Tools":
User is tp, password is tp.
Change the Drive to B: in the right column. All measurement data are in the
subdirectory :
B:\httpd\htdocs\daten
CDF-Freeze Thaw- Testing Machine page 6
All program iles in:
B:\httpd\cgi-bin.
For advanced users: As super user you may also have an access to the machine
via Telnet:
User is tel, password is tel.
In the telnet window a command line terminal will be opened. Here you may use
most o the usual DAS commands. Press help Enter i you are in doubt. Give the
command closetelnet to close the connection.
2.2.2 CompactFlash Card
You may also read the data iles
rom the built in CF card.
Switch o the machine. Open the
electrical cabinet. On the le t side
you will see the electronic.
Remove the card.

3 Principles of Operation
3.1 General
The CDF reeze-thaw testing machine is developed ollowing the CDF standards
o RILEM-(Materials and Structures (1996) Vol 29 (193), pp 523-528), the RILEM
CIF standard and prEN 12390-9. The main advantage o thees standards is the
very good reproducibility o the measurement results. The specimen containers
are hanging in an coolant liquid. So you get a constant temperature distribution, a
ast temperature balance and temperature gradient right to tested specimen
sur ace. Due to the low thermal resistance the temperature deviations are very
small.
BetonLuftPrüfflüssigkeitühlflüssigkeit
Kühl lüssigkeit = coolant liquid; Prü lüssigkeit = test luid, water or water with
salt; Lu t = air; Beton = concrete
Also the cube test according to prEN 12390-9 may be run (option) by the CDF
machine. In opposite to air cooled test chambers, the cube test cycle may be
shortened rom 24h to 12h. This cuts testing time and costs dramatically..
3.2 System Operation
The CDF machine is a bath o circulation coolant liquid. In the bath stainless steel
containers are mounted. The concrete specimen is placed on three small spacers
in the middle o this containers. Each container is illed with some amount o water
or water/ salt solution. The coolant liquid, and so the specimen, are rozen and
thawed in a well de ined temperature cycle.
The re erence temperature is measured at the bottom o the container. Be shure
that minimum one container is in contact with the probe.

The coolant liquid is circulated by pump 1. In the circulation a electrical heater is
mounted. For cooling a dosage o cooler liquid, cooled in a special bu er
container, is added by two magnetic valves. The coolant in the bu er is pumped
in a 2nd circulation through the evaporator, which is cooled to -38°C by the
compressor, back to the bu er. The bu er-temperature is always below the
temperature in the main circulation. The compressor is cooled by air, water or
water + air.
