remove it.
1. Refer to Figure 8. Turn the gas-ballast control (1) to the high flow position (position 'II').

slightly to release the bayonet-lugs (5) and remove the control.
3. If necessary, wipe the control with a clean, dry, lint-free cloth and check that the air-hole (3) is not blocked.
4. Refit the control into the gas-ballast inlet and ensure that the compression spring locates correctly between the
bayonet-lugs.
5. Push the control down as far as it will go and then turn the control clockwise slightly until the bayonet-lugs
engage correctly.
6. Reset the gas-ballast control to the required position.
