Kühlflüssigkeit = coolant liquid; Prüfflüssigkeit = test fluid, water or water with salt; Luft = 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 from 24h to 12h. -

Page 11: Testing Tub
In the testing bath the cooling liquid is circulation to ensure a balanced thermal distribution. The gastro norm specimen containers are hanging in the cooling bath. Below the bath the coolant buffer is mounted. 3.3.2 Circulation Unit CDF-Freeze Thaw- Testing Machine page 11... - Page 12 First Time you thin down the glycol coolant with 40 % of water, so that the freeze protection ist -45°C. If you fill all the coolant in the testing-tub the additional liquid comes over into the buffer and the valves. CDF-Freeze Thaw- Testing Machine page 12...

In opposite to air cooled test chambers, the cube test cycle may be shortened from 24h to 12h. This cuts testing time and costs dramatically. - Page 15 Please don´t forget to put the filter over the outlet. Put in most of the specimen containers and fill in additional coolant liquid. Check the liquid level at the level indicator right in front of the instrument. CDF-Freeze Thaw- Testing Machine page 15...

3.6 Transport of the CDF Machine Empty the coolant from the bath and the buffer, if you like to transport the CDF machine. Lift the machine only at the frame below the bath, never at the coper plates or the electrical cabinet. The cover plates should be fixed additionally, or be transported separately. -

Page 18: Handling The Controller
The main switch of the machine should be on at least one hour, before you start a test-run. Therfore the compressor is preheated, the lubricant inside is getting fluid, and the cooling gas is separated from the oil. Otherwise a over pressure error may CDF-Freeze Thaw- Testing Machine page 18... -
Page 19: Status
The cycle time may be set in the appropriate menu. With the CDF test 28 cycles a 24h are run. You may also activate other cycles. If the last cycle is over, the temperature will be kept constant at 20°C. So if you start a new test-run, you have to reset the number of cycles and the cycle time. - Page 20 If a security protection switch is on, it is shown in this menu by an inverse button The actual temperatures are shown in the screen below: CDF-Freeze Thaw- Testing Machine page 20...

Page 21: Cycle Time
The cycle time is defined in hours (h) and minutes (min). Hint: You may start the machine at any time. If you like to start the CDF test at 10 am, and the scaling test should be between 1:00 pm and 3:00 pm so adjust the cycle time to 7h 30 min. -
Page 22: Target Value
4.4.1 Target Value Beneath a temperature profile, you may the CDF machine also run at fix temperature. After you put in a temperature here, the machine will run this temperature, until it is stopped again. If the machine is restarted it continues the last active cycle. - Page 23 1. The control algorithm is optimized for the CDF test. Each modification may reduce the controlling quality. As a worst case the controller is no longer stable. 1. The refrigerant installation is also optimized for the CDF cycle. Avoid temperatures below -20°C.

Five points define 4 profile-segments. The number of cycles depends on the test method (CDF = 28 CIF = 56). If you like to run a cycle at infinity, you may define the number of cycles as 32000 which means 43 years. -
Page 25: Clock
In the clock menu you can set date and time of the real time clock. The controller distinguishes between the cycle time and the real-time clock. The cycle time may be set in the Main-Menu – Cycle Time CDF-Freeze Thaw- Testing Machine page 25... -
