tion PCB (D1).
2. Fit the housing’s back part (A8) into the housing’s upper part (A6).

position the controller PCB into the corresponding guides in the upper part of the housing (A6).
Check the position and fit of the back part.
4. Fit the cover for the check valve. Ensure that the fastening tabs on both sides snap in audi-
bly and that the interior wall (A17) sits behind the cover for the check valve. It should also be
ensured that the cover fit exactly onto the slot of the bellows (A7).
5. Fit the battery pack and connect the battery pack PCB (F3) to the controller PCB (A9).
