Helpful Hints
■
Empty the black water fi rst. Use gray water to rinse the
hose after emptying the black water.
■
Additional hoses can be purchased from Thetford and used
to extend the length of the discharge hose. Connect the
hoses using 1.5 in. (3.8 cm) barbed coupling with clamp.
■
If you wish to extend the discharge hose, connect a 3/4
in (1.9 cm) inner diameter garden hose to the end of the
nozzle. Do not extend the hose beyond 150 ft. (45 m).
A longer discharge hose reduces fl ow rate.
NOTICE
■
Before storing the hose, make sure that all liquid has
drained from the hose.
