compartment R.H. side (1, Fig. 25). A third tube
connected in the bottom of the fresh water tank
allows fresh water to flow to the washbasin
faucet. Water from washbasin drain tube flows
to the main sump tank.
Also, a drain hole located on lavatory floor drain
water splashed on the floor to the engine
compartment R.H. side.
6.2 MAINTENANCE
The servicing procedure for the lavatory is
described in the '‘Operator’s Manual'’ included in
the technical publications box delivered with the

6.3 VENTILATION FAN
6.3.1 Description
The lavatory ventilation fan, mounted in engine
compartment behind the oil reserve tank (Fig.
23), 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 on the lavatory door and
exhausts through a grill located next to the toilet.
NOTE
This fan runs constantly when the ignition
switch located on the dashboard is in the "ON"
position.
6.3.2 Maintenance
The frequency of preventive maintenance
should be determined according to vehicle
mileage and operating conditions. However, it is
recommended to check this item every 50,000
miles (80 000 km) or once a year, whichever
comes first.
Remove fan and motor assembly. Check for fan
housing wheel and motor free operation. When
defective motor occurs, new motor must be
installed.
6.3.3 Removal and Installation
1. With the engine compartment rear doors
opened, remove hose clamp securing duct
to ventilation fan inlet, and disconnect duct.
2. Disconnect the ventilation motor wiring
connector.
3. Remove the support bracket screw. Remove
the three bolts fixing the ventilation fan
housing support. Remove the ventilation fan
assembly from its location.
4. The unit can now be disassembled and
motor replaced.
5. Reverse previous steps to reinstall
ventilation fan assembly on vehicle.

6.4 DOOR LOCK
Lavatory door lock has inside and outside
handles, as well as an inside latch to lock door
from inside the compartment. If the lock fails to
release, the door can be opened from the
outside using a special key which is supplied to
the driver. Lock assembly can be removed from
the door, then readily disassembled and parts
replaced, if necessary (Fig. 24). A thin coat of
lubricant on all moving parts will ensure
trouble-free operation.
