4) Remove the old gasket by sliding it out of its seat. Clean the seat of the gasket with neutral detergent (Fig.
5).
5) Starting at the centre back of the seat in the cover (on the side of the hinges), fit the gasket in all the way
round (Fig. 6) making sure to do the following:
a) Make the two cuts in the gasket in a neat and precise manner.
b) Check the lip of the gasket faces outwards.
c) Do not stretch the gasket when fitting it in.
6) Re-attach the gas spring, inserting the pin and locking it in place with the elastic ring that was previously
removed (Fig. 7).
7) Run a cycle with the vacuum set at maximum. When the maximum pressure is reached, turn off the machine
at the main switch: the chamber will be pressurized with the cover down. To check successful operation,
wait for 5 minutes with the cover closed and the chamber pressurized.
