FILLING THE MAIN SUMP TANK
Fill the main sump tank through the access hole
and throw in a packet of commercial toilet
deodorant (Prevost part #900329).
DRAINING THE MAIN SUMP TANK
When recirculating water in the toilet is soiled,
drain the sump tank. If equipped with the
optional auxiliary sump tank, drain the main
sump tank contents into the auxiliary tank by
opening the knife gate valve under the tank.
Perform the filling procedure of the main tank.
DRAINING THE AUXILIARY SUMP TANK
To drain the sump tank contents, turn the drain
valve lever counterclockwise about eight or nine
turns. Remove the access cap and flush tank
with clean water. To close, turn the drain valve
lever several turns clockwise until the rubber
bladder seals the drain hole. Reinstall the
access cap.
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.
