LAVATORY
OESCRIPTION
Washroom facilities are installed at the right rear corner of
the coach. Installation of the washroom elin::iinates seating for
two passengers. leaving three seats on the rear cross seat
The washroom (figure 17-1) has a special, embossed stain-
less steel floor with stainless steel bright finish paneling on the
lower half of the walls. door and sink partition. Permanent finish
melamine panels are utilized on the upper half of the washroom
partitions for ease of cleaning and resistance to damage. A
large mirror is mounted on the back wall above the wash basin.
Extreme care has been taken in the design of the washroom to
avoid corners where dirt may collect. The use of stainless steel
enables the washroom to be easily maintained in a pleasing
condition at all times.
A single waste water and chemical tank with bottle stop in
drop tube is used. A stainless steel fresh water tank for the wash
basin is located in the interior of the coach behind the wall
mirror. A large overflow line is provided on the fresh water tank
to eliminate the possibility of damage by excessive water pres-
sure. A manually operated slide dump valve is provided to drain
the chemical tank.
A coupling which provides water to the fresh water tank is
easily accessible through a small door on the right rear side of
the vehicle. A coupling for flushing and filling the chemical tank
1s accessible through the right hand rear side engine service
door.
. 'ENTILATING BLOWER ANO MOTOR
A ventilator blower mounted on the chemical tank exhausts
odors and also provides constant air circulation to the lavatory
compartment. Air enters the lavatory compartment through a
duct on the outer wall which discharges behind the window
release bar.
The exhaust blower operates whenever the master control
switch on the driver's instrument panelis put in the ON position.
The blower motor is rubber mounted and can easily be
removed from the engine compartment by removing the mount-
ing screws and separating the electrical wires at the connectors.
NOTE: Later production coaches have a
ventilation system without the blower and
motor {unless the blower and motor have
been retained by special request). Infor-
mation on this newer system will be found
later in this section.
MAINTENANCE
Tl'le frequence of pre11entalive maintenance should be
determined by coach mileage and the operating conditions.
However. these items should be checked approximately every
50.000 miles (80,000 km) or 1,700 coach operating hours.
Remove the blower and motor assembly (see figure
17-2).
Free operation of blower wheel and motor is important. Check
blower housing wheel and ducts. If dirty. they should be
cleaned.
