4.10 Cooling Mode Switching Valve
(optional)
The cooling mode switching valve is optionally avail-
able and allows to easily switch between com-
pressed-air cooling and liquid nitrogen cooling
without the need of connecting or disconnecting any
hoses at the backside of CCU 100.
Fig. 32: Installation diagram
Fig. 33: Cooling mode switching valve
The valve is delivered with 4 m additional hose.
Install the cooling mode switching valve as follows:
1. Connect the AIR OUT of the cooling mode
switching valve to the connector AIR OUT on
the rear side of CCU 100.
2. Install the Liquid Nitrogen Equipment as
described in chapter 4.8. In step 4 connect the
compressed air connector on the box (4) in
Fig. 17 to the LN2 COOLING connector of the
cooling mode switching valve instead of connec-
tion to the CCU 100.
3. Install the Air Cooling equipment as described in
chapter 4.9. In step 6 connect the compressed-
air hose to the AIR COOLING connector of the
cooling mode switching valve instead of connec-
tion to the CCU 100.
4. In order to use Air Cooling or Liquid Nitrogen
switch the cooling mode switching valve to the
corresponding position and install the air-cooling
equipment (Fig. 31) or the Low Temperature
Equipment (Fig. 30) to the chamber (5 on
Fig. 5).
4.11 Mounting the Gas/Vacuum Con-
nector
The gas/vacuum connector allows to supply and ex-
tract gas from the TTK 600 and to apply vacuum to
the chamber. The gas/vacuum connector is mount-
ed to the lid of the TTK 600.
4.11.1 Installing the Gas Supply (optional)
Depending on the measuring problem, the TTK 600
can be operated with different gas atmospheres,
e.g. air, inert gas or nitrogen.
Apart from the explicitly specified gases, other non-
hazardous gases can be used, provided the gas it-
self and possible reaction products with the sample
do not damage the instrument. A list of chamber ma-
terials is given in appendix A.
Gases can be supplied to and extracted from the
chamber by using the gas/vacuum connector and a
blind cover delivered with the chamber (see
Fig. 34). The gas/vacuum connector is equipped
with two hoses for gas inlet and outlet. The direc-
tions of in/outlet are marked on the gas/vacuum
connector. Each hose contains a quick coupling
connector with a valve to open/close the gas inlet/
outlet.

DANGER
Risk of damage.
Poisonous, explosive or corrosive gases must
not be used.
