Lid Assembly Removal
6.13.1 Remove tub assembly as per instructions in 6.11
6.13.2 Disconnect the lid plumbing off the exhaust valve and air pump above the 'Y' joint.
6.13.3 Release two locking tabs securing the front of the lid to the chassis.
6.13.4 To do this, push back the tab in the center of the rectangular slot at the front of the
lid molding, using a blade screwdriver, then apply downward pressure to the lid
while holding the tab back.
6.13.5 The lid will now drop into the chassis opening and this will allow it to be slid
forward out of the chassis area.
6.13.6 Refit in reverse manner being careful not to damage the seal when fitting the lid in
through the chassis. Ensure the location tab at the right rear of the lid locates to
the right of the rear chassis support.
Note: The bottom lid has a strengthening bar at the rear.

Lid Seal Replacement
6.14.1 Remove Lid assembly as per instructions 6.13.
6.14.2 Remove the seal by grasping hold of it in the middle and easing it away from the
lid. This will release the fir tree part of the gasket from the retaining slot.
6.14.3 Ease the gasket away from the air plumbing connector joint at the rear of the lid.
6.14.4 Fit the new up to the shoulder on the plumbing connection. Slide both ends of the
lid seal into place ensuring they rest against the stops.
6.14.5 Lay the gasket in the approximate position around the lid.
6.14.6 Press the gasket into position at each corner. The fir tree section pushes into the
lid slot.
6.14.7 Now the rest of the gasket can be pushed in around the lid section.
Note: This is a push in seal and does not require a sealant.
6.14.8 Testing the gasket with an extension piece of air plumbing, air gauge and air
supply before fitting would be advisable. Pump the gasket up to 6psi and then
pinch off the supply. The pressure should not drop below 4.5psi over a 60-second
period.
6.14.9 Refit lid as per instructions in 6.13.6.
