CLEANING CABINET
A hose connection and valve is located behind a
small door in the top corner of the rear lavatory
wall, over the mirror. It can be used to attach a
garden hose for lavatory cleaning. To use,
connect a fresh water supply to the connection in
the curb-side engine compartment, identified as
"Cleaning Kit", located next to the fresh water
reservoir fill coupling.
To prevent freezing during cold weather, drain the
hose after every use.
FILLING THE MAIN SUMP TANK
Open the main sump tank overflow cock and
connect a water supply hose to the toilet sump
tank fill connection. The main tank is full when
water starts flowing through the clear overflow
tube. Close main sump tank overflow cock when
the tank is full.

2. Main sump tank fill connector;
3. Main sump tank overflow cock;
4. Cleaning kit hose connector;
5. Main sump tank drain valve;

DRAINING THE MAIN SUMP TANK
When recirculating water in the toilet is soiled,
drain main sump tank. If equipped with the
optional auxiliary sump tank, drain the main
sump tank contents into the auxiliary tank and
perform the filling procedure of the main tank.
DRAINING THE AUXILIARY SUMP TANK
To drain the auxiliary sump tank contents,
remove the cap located underneath the tank
then turn the drain valve lever counterclockwise
about eight or nine turns and pull the lever up.
Remove the access cap and flush tank with clean
water. To close, push the valve down on its seat
then turn the drain valve lever several turns
clockwise until the rubber bladder seals the
drain hole. Reinstall both caps.
CAUTION
Lavatory tanks should be serviced only at
suitably equipped stations.
NOTE
It is unlawful to dump sump tank contents in
any location other than those designated as
such.
When a complete tank draining is required,
clean main tank by repeating the draining and
filling operations while leaving the auxiliary sump
tank drain valve opened. Close valves and drop
in a packet of commercial toilet deodorant
(Prevost part #900329) in toilet before starting
final filling of the main tank.
WARNING
The toilet deodorant contains compounds
which can be very irritating to skin. Use rubber
gloves when handling and then clean toilet
seat.
CAUTION
When cold weather is expected, both sump
tanks must be drained if the coach is parked
overnight or for an extended period of time.
NOTE
Due to the heat it produces, there is less risk
of freezing in the tanks when the engine is
operating.
NOTE
New coaches are delivered with the sump and
fresh water tanks empty. Fill with water before
putting the coach in service.
