1.
Ensure the CoolSafe is switched off and the vacuum has been released
2.
Leave the condenser open to the atmosphere, introduce warm water into the
condenser until it is released from the walls of the condenser. Then remove the
ice
In both cases, with or without electric de-icing, once the ice has been removed, open
the drain valve to remove any remaining water. Thoroughly dry the condenser using
disposable tissues, spray with alcohol and wipe dry, ensuring there is no retention of
any liquid in the drain.
5.6. Stopping the vacuum pump
Close the (external) vacuum valve and let the pump run for a minimum of 45
minutes after the freeze-drying has ended. This is to avoid any possible condensates
remaining in the pump oil.
If the freeze dryer is used regularly during the day/ week, it is recommended that the
vacuum pump runs constantly with gas ballast valve open and the vacuum valve
closed.
6. Alarms and errors
In case of alarms or errors, an alarm/error code will be displayed.
E_1: Error indicating that the temperature sensor has a short circuit.
E_2: Alarm indicating that the temperature during freeze-drying is above -40 °C.
E_3: Error indicating that the temperature sensor is disconnected.
7. Maintenance
7.1. CoolSafe
The air-cooled condenser must be cleaned a minimum of twice a year. Use a vacuum
cleaner and remove any dust in the cooling grill on the front.
7.2. Vacuum pump
See the Instruction Manual for maintenance according to the manufacture’s
recommendations. Maintenance for a vacuum pump in general will be to:
Check the oil volume, colour and condition regularly. The oil should be
changed every 400-500 working hours, more often if the pump has been
exposed to aggressive vapours. This is best done when the pump/oil is warm
Keep a Log book of the usage periods.
Drain the oil mist filter if the oil level is more than 10 mm.
Drain, clean and eventually change the filter insert if vapours are emitted
