1 Introduction
We congratulate you on the purchase of the CDF test equipment. With
this equipment, you have acquired a high-quality test device for the real-
ization of the freeze-thaw resistance test. Equipped with a microprocessor-
controlled controller with internet interface, the device complies with the
state of technology and thus meets the requirements of the future. Dur-
ing the execution of the equipment, the relevant safety regulations for
refrigeration and electrical systems were taken into account.
The technology of the system is easily accessible from all sides thanks
to removable panels. Thick meticulously executed piping insulation and
the transverse ventilation of the unit part reliably prevent condensation.
Very good fit of all components is achieved by the use of CNC punching
and CNC bending presses. Robust surfaces result from powder coating
of all sheet metal parts.

2 Safety instructions
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 of not instructed people
are present. So there are no special requirements in the training of the
people working with, or nearby the machine.
A mix of 45 % water and 55 % glycol is used as a cooling liquid. Ac-
cording to the European water protection standard the cooling liquid is
assigned to level 0. There are no special requirements for environmental
or water protection for cooling liquid.
Until 2017, the CDF machines were built with the refrigerant R507. Since
2017 the Schleibinger CDF machines are being built with the refrigerant
R448a. Compared with CO2(GWP = 1.0) R448a has a high potential for
global warming (GWP = 1387) but lower than the previuous used R507
(GWP = 3800). This fact requires a careful handling with the refrigerant.
Service and repair jobs at the cooling machine are allowed only for well
trained and special educated persons. Please contact Schleibinger for
further questions.
The lubricant of the cooling machine is long-term stable and does not
need to be changed during the service life. The oil is classified at water
dangerous class 1. There are no special oil protection requirements
necessary. The CDF machine stops automatically when a leak occurs
in the system.
The CDF test machine has a mains connection with a 3x 32A/400V/50Hz
CEE connector. As circuit protection 3x 32A are necessary.
While using CDF equipment the environmental conditions should be at
10 to 28 °C at maximum 65 % relative humidity. At higher humidity,
more condensation may be present on some machine parts. Below 10
°C, a special winter controller should be ordered with the machine. At
temperatures above 28 °C additional water cooling system is required.
Opening the lid of the cooling bath is only permitted if the bath
temperature is close to room temperature. We strongly recommendAttention!
using waterproof isolation gloves for protection. Contact to the cooling
bath at low temperatures may cause freezing the skin.
2.1 Protection switches
The CDF machine is equipped with the following safety and security
components, which are adjusted by Schleibinger.
• Overtemperature protection for the heating unit (70 °C)
• Level indicator for the testing bath and the buffer.
• Safety switching device for limiting the high pressure for the com-
pressor.
• Safety switching device for limiting the low pressure for the com-
pressor
Changing the setup of the security devices is prohibited! Any ma-
nipulation will lead to a total warranty loss!Attention!

2.2 Personal safety
To ensure the greatest possible protection for employees using the freeze-
thaw equipment follow carefully all standards and laws for personal pro-
tection and the standards EN 378-1 and EN 378-2 as well.
• Do not swallow the heat transfer medium (cooling liquid) and an-
tifreeze concentrate (glycol)!
• Avoid skin contact!
• Avoid eye contact!
• Risk of frostbite on prolonged skin contact and appropriate tem-
perature!
During hanging and removal of the sample containers:
• Avoid contact with skin. Wear protective gloves!
• Avoid contact with eyes. Wear safety glasses!
2.2.1 First aid
In case of contact with heat transfer fluid follow the instructions:
• In case of contact with eyes, rinse immediately with plenty of water
and seek medical advice.
• In case of contact with clothes and skin, take off immediately all
contaminated clothing and wash the skin immediately with plenty
of water for a minimum of 10 minutes.
2.3 Safety instruction for cooling liquid
• Frostbite at low temperatures and direct skin contact.
• Intake via the skin can lead to health problems.
• Ingestion may cause damage to health.
• May irritate the respiratory system, eyes, skin, digestive tract.
• May cause nausea, vomiting, dizziness, convulsions, arrhythmia,
difficulty breathing, impaired vision, kidney damage, liver damage,
and neve damage.
• Pentration into soil, water and sewage system is to be avoided.
2.3.1 Protectives and behavioral rules
• Do not leave the lid of the CDF machine open.
• Cover not used place in the CDF bath with some cover plates or
dummy containers.
• Wear eye/face protection.
• Wear suitable gloves.
• Avoid splashing when refilling.
• Avoid splashing when taking sample container.
• Do not use reactive substances.
• Do not eat, drink or smoke.

2 Safety instructions 7
• Avoid breathing vapors.
• Avoid contact with eyes, skin and clothing.
• Immediately remove product residues from the skin, gently clean
the skin and dry thoroughly.
2.3.2 Reaction to malfunctions
• In the case of safety-endangering defects and malfunctions, do not
use the device and inform those responisible.
• Collect spilled liquid with adsorbable non-sombustible material (such
as diatomaceous earth, sand) and dispose it according to local
regulations.
• In case of fire: use fire extinguisher. Do not use water in the full
jet! Do not breath fumes!
2.3.3 Disposal of the cooling liquid
• Avoid release to the environment.
• Do not empty into drains; dispose of this material and its container
in a safe way.
• Completely emptied or cleaned metal containers can be released
for scrap utilization.
• Completely emptied or cleaned plastic containers can be returned
for recycling.
2.4 Safety instructions for the refrigerant
The refrigerant R448a belongs to the group L1 according to EN 378-1.
It is not flammable and has no significant harmful effects on humans.
• The refrigerant is heavier than air and collects in the event of leak-
age on the ground.
• It is hardly noticeable by smell.
• At high concentrations, oxygen deficiency may occur. There is
danger of suffocation.
• When inhaling high concentrations, there is the possibility of car-
dac sensitization by adrenaline. It can lead to cardiac arrythmias
until cardiac arrest.
• Liquid refrigerant on the skin and in the eyes cuses frostbite.
• In case of leaks, protect hand and face with gloves and safety
glasses.
• Open flame or very hot surfaces can cause decomposition of the
refrigerant, producing very toxic gases. Smoking and open flames
are therefore prohibited.
• Ask for service for finding leaks!
Do not change safety, protection and control devices! When refilling,Attention!
use only the refrigerant R448a. Refrigerant may only refilled in a liquid
state.
• In case of fire, switch off the refrigeration system. Containers and
system parts that are filled with refrigerant can burst violently.
• When extinguishing, cool the container and system parts with wa-
ter spray.

3.1 Set up of the CDF test equipmpent
The floor should be designed for a load of at least 300 kg/m2. For a
purely air-cooled system, the room size should be at least 200 m3and
be well ventilated to dissipate the waste heat. According to EN 378-1,
the volume of the room should be at least 8 m3in terms of any escaping
refrigerant.
For the set up of the CDF equipment, please ensure free air circulation
around the equipment (2).
The CDF machine should be set up to be level. Please check this by a
level at the testing bath (3). If necessary, the device can be leveled with
four adjustable feets. It should be adjusted to ±1 mm/m exaclty.

3.2 Configuration of the Network access
The Schleibinger data logger, the Slabtester and the CDF machine are
equipped with a 100 BaseT network interface. It can be integrated within
a local Intranet or globally into the Internet. The network configuration
can be done with the program Chiptool which can be found on USB stick
delivered with the equipment or downloaded from the page:
www.schleibinger.com/chiptool .
Example of Default Settings:
Device: Data logger for the shrinkage cone
Customer: Miximaxi AG
Serial Nr: 201312324
MAC-ID: 00:30:56:90:7D:C3
Hostname: Scone_201312324
[] Obtain an IP-Address automatically
[] Use the following IP-Addresse: IP addresse:.......
Subnet mask:.......
3.2.1 Network configuration between data logger and PC
There are two options for the network configuration of the data logger
and PC available:
• by automatically getting an IP address = default setting at time of
delivery
• by using a static IP address
Automatically getting IP address
Connection of the data logger into a local network with DHCP- and DNS-
Server is the simplest and fastest method.
• Connect the data logger with your local network (switch) using the
network cable which was delivered with the device and switch on
the data logger (24V adapter)
• Enter the host name into the address line of your browser in a form
"http://. . . " (Fig. 4.)
A DHCP-Server assigns a free IP address to the data logger. You can
access the data logger via the default host name using the DNS (Fig. 4).
Hint: DHCP server are scanning the network from time to time assigning
a IP address and a symbolic name to all computers in the network. This
procedure may take some time. So please wait some minutes until you
try to access the data logger with its host name.
Alternatively, in the case the host name - DNS-server does not work or
supported in your network the connection with the data logger can be
done by using of the assigned IP address. This IP address can be found
from the program Chiptool, mentioned above (Fig. 5).
Make sure the data logger always getting the same IP address from
the DHCP server. Enter the IP address assigned by the DHCP server
into the address line of the browser instead of the host name (Fig. 6).
