THERMASAN
SYSTEM
The Thermasan System has been carefully
designed to minimize the need for routine main-
tenance . All bearings are lifetime oiled and
sealed
. No
lubrication
is required . Furthermore,
adjustments to the system are not required .
Rear
Suspension Air Compressors
Thermasan components may adhere to the
exhaust system, even though the contacting
components
are made of stainless and other
special steels .
Any time the Motor Home ex-
haust system is being
worked on care should be
taken not to damage
any of the Thermasan
components .
Occasional draining of the
holding tank at an
approved dumping station is
recommended . This
should be done at least annually to remove
any
foreign particles or other insoluble matter .
There is no routine maintenance required on
the standard toilet . If a problem occurs, check
and
make the appropriate correction .

STANDARD TOILET
Water keeps
running into the bowl .

closing completely,
which in turn keeps
the water control valve
partially open .
