7.1 Running the Pump Cleaning Programme
The pump cleaning programme runs the vacuum pump for 15 minutes. During the programme, the
pump and the oil reach the operating temperature. Moisture in the pump is absorbed by the oil.
The high temperature causes any moisture in the pump to evaporate, and minimises the risk of
corrosion.
It is advisable to run the programme before using the machine for the first time, after the machine
has been stationary for a lengthy period of time, and especially prior to changing oil.
Run the pump cleaning programme every week. If you package moisture-containing products,
such as soups and sauces, the pump cleaning programme should be run every day.
