TwinDos cartridges: changeover from film seal to caps
TwinDos cartridges can be sealed with a film seal or a cap.
Risk of damage from film seal:
If the film seal is not removed completely from the TwinDos cartridge, leaks can occur in the TwinDos system.
Remove the film seal or the cap from the suction port on the cartridge completely before inserting the new TwinDos cartridge.
