Replacing the door glass, seal tape and door seal rope

Open the door fully. You will see the glass is retained by a frame that clips into the hinge at the
right side (facing the inside of the door) and held by two screws at the left side. The door seal rope
is fitted into a groove formed in the glass retainer.

To replace the door seal rope:

Pick out one end of the door seal rope at the join which is located centrally at the right
hand (hinge) side. Pull gently along the rope until it is all out.

To replace the rope, first dab a spot of Mani-seal into the groove formed by the glass
retainer at all four corners and the centre of all four sides. Position the rope into the
groove, starting at the center of the side next to the hinge and working around until the
ends meet. There should be a tight join at the ends to prevent air leaks.

The door may appear excessively tight when the door rope has just been replaced. The rope
needs to bed in, and this may take a number of openings and closings of the door to achieve.

To remove the door glass:

Open the door and remove the two small screws holding the left (door handle) side of the glass
retainer in place. Lift the left side of the retainer and glass away from the inside of the door, until it
is clear of the door frame then pull the right end out from behind the hinge. Ensure the glass does
not drop out of the retainer frame while this is being done.

Lay the glass and retainer down on a padded surface and push out the glass from the back of
the retainer frame.
