7. Check the canopy seals:
a. If the unit has original canopy seals, which are attached with fasteners, check for visible cleanliness.
b. If the unit has enhanced canopy seals, which can be removed by hand, check the following:
• Check for visible cleanliness.
• Make sure that all seals (the two south corner covers, the two long side seals, the short south seal,
and the notched north seal) can be easily removed and reinstalled. For details, refer to section 5.2.1,
steps 10 and 15.

porthole and check that the latch holds the cover securely shut and that the cover seals tightly against the
porthole gasket. Check that all the porthole seals are in place and are in good condition.

check to see that the bed platform extends and stops when it is pulled out on either side. Check the
operation of the bed tilt mechanism. Squeeze the tilt control and push down on the foot of the bed. The
head of the bed should raise easily, and should stay in position at any angle along its tilt path when the tilt
