To release, simply disengage the sunshade from
the moldings and release. Spring tension will pull
back the sunshade to the full open position.
Correct spring tension is set at the factory and
should not need further adjustment.
However, if for any reason a sunshade has to be
removed from the vehicle, preloading of the
recoil mechanism will be required before re-
installation to ensure that the sunshade returns
to the full open position when released.
CAUTION
A special tool is required to remove the
sunshade from the window support. Failure to
use the special tool will result in permanent
damage to the sunshade and/or window
support.
The special tool can be ordered from your
Prevost part center under part # 685594

VENTILATION FAN

The lavatory ventilation fan, mounted in engine
compartment over the oil reserve tank (Figure
25), serves two purposes. It exhausts objection-
able odors and provides a constant air circula-
tion in the lavatory compartment by heating or
cooling the lavatory with the vehicle ambient air.
Air flows in the lavatory compartment through a
vent grill located in the upper section of the
lavatory door and exhausts through a grill
located next to the toilet.
