NOTICE
Before each use: With seat cover closed, open
and close the holding tank valve (Figure J11) to
vent any pressure that may have built up as a
result of heat or altitude. This prevents upward
splashing of bowl contents when toilet is flushed.

D. Head With Overboard Discharge
This option is available on most Vista™ models. The
head toilet operations are the same as the systems de-
scribed earlier but an additional line with a "Y" has been
installed for overboard discharge. The waste will be pumped
into the holding tank from the head. The macerator pump
is installed after the "wye". Refer to Figures J5 & J14.
