gas cylinder to the coupling pos. 105. The coupling is on the left side of the service
cart. Open the cylinder valve on the SF

-gas.
2. Start the compressor with the <F1> key.

evaporator has reached its operating temperature.
4. The cylinder pressure can be read on the gauge pos. 162 (at coupling pos. 105).
Observe the filling weight of the storage tank (1kg/l)!
5. After having reached the desired filling weight in the SF
6
cylinders switch off the solenoid valve pos.
137 and the compressor by means of the corresponding keys on the operating panel.
6. Close the cylinder valve on the SF
