Preparations
Check that the CoolSafe ice condenser is free from ice and water, and that all valves i.e. the drain
valve is closed. Check that there is no water in the drain valve.
Note
Do not use any tools to close valves, as they will easily be damaged.
Check that the gas ballast valve on the vacuum pump is open at all times.
Check the oil level in the pump and the oil mist filter. The filter should have only a maximum
10 mm oil level (preferably it should be empty).
Switch on the CoolSafe and the vacuum pump.
The lowest temperature (-100 °C on the CoolSafe 100-9 Touch Superior XS and -95 °C with
CoolSafe 95-15 Touch Superior XL) should be achieved within 60 minutes.
The vacuum pump should now be allowed to run for at least 30 minutes to achieve the
lowest vacuum performance. In this "warm up" phase the gas ballast control ideally should
be open but closed during the primary and secondary drying phases. Please note that
vacuum will not be applied to the condenser at this juncture. The electronic vacuum valve
