Lubricate the plastic trim plugs

  1. Remove the plastic trims.
  2. Make sure that the roof body cover and wall body cover are vertically aligned.
  3. Apply washing liquid to the plugs in the plastic trims.
    Note: Do not use any oil-based liquid as lubricant. It could damage the body covers.
  4. Install the plastic trims.
    Tap the area around the plastic trim plugs to make the trims fit.
    Note: Make sure that the plastic trims are installed the correct way round.
