the waste is moved through the
vacuum tank, the vacuum pump
and ends in a holding tank.
The change in pressure in the
vacuum tank causes the integral
pressure switch to activate the
vacuum pump.
Step 2: After the ush lever is released
the vacuum pump continues to
run until the vacuum level is re-
charged in the system. Recharg-
ing the vacuum takes about one
minute. To ush the head, press
the ush lever sharply down to
the deck until the contents clear
the bowl. A sharp popping noise
is normal when the vacuum seal
is broken. Hold the lever down
for three (3) seconds. After
ushing, let the lever snap back
into position. If the ush lever
is accidentally released before
waste clears the bowl, do not
ush again until the vacuum
pump stops running. A small
amount of water remains in the
bowl after ushing.
Step 3: Do not dispose of sanitary nap-
kins or other non-dissolving
items in the head. These items
can cause plugging of the sys-
tem.
Following operation:
Step 1: Dispose of waste properly. (DO
NOT DISPOSE OF WASTE IN
ANY LOCATION, INCLUD-
ING NAVIGABLE BODIES
OF WATER, WHERE SUCH
DISPOSAL IS ILLEGAL OR
CREATES AN ENVIRON-
MENTAL HAZARD.) See ma-
terial supplied by the manufac-
turer.
Special Attention:
Use only rapid-dissolve toilet pa-
per with these head systems, and only
deodorant specially formulated for this
type of head system. See the manufac-
turer’s instructions for details. In the
event that anything from the head’s bowl
or holding tank escapes, it should be
cleaned as soon as practicable. Failure to
clean any spillage may result in unpleas-
ant odors, mildew, mold and damage to

the deck or other areas of the boat. This
is not covered under warranty.
Additional Special Attention:
See the Storage & Winterization sec-
tion of this Owner’s Manual for impor-
tant information regarding the prepara-
tion of the head for storage.
Troubleshooting:
Proper use of the head should avoid
issues. However, if for any reason the
head does not operate as indicated, re-
fer once more to the instructions. In in-
stances of malfunction, take the boat to
an authorized MasterCraft dealer for as-
sistance.
Removable Coolers
Models:
All models.
Purpose:
The coolers allow for boaters to bring
food and beverage onboard for outings
and keep such items at a lower tempera-
ture than ambient air, and from spoilage
as rapidly as would otherwise occur.
