DENALI 28
IN MANY AREAS IT IS ILLEGAL TO FLUSH HEAD WASTE DIRECTLY OVERBOARD. VIO-
LATION OF THESE POLLUTION LAWS CAN RESULT IN FINES OR IMPRISONMENT. AL-
WAYS KNOW THE LAW FOR THE AREAS IN WHICH YOU BOAT. NEVER DUMP HEAD
OR HOLDING TANK WASTE OVERBOARD ILLEGALLY.
Holding Tank and Macerator Discharge Pump
When the holding tank is full it must either be pumped out by an approved waste dumping station
through the waste deck fitting or be pumped overboard with the optional macerator discharge
pump, when legal to do so. When the macerator discharge pump option is installed, the Y-valve
is used to select the waste deck fitting or the overboard macerator discharge pump.
To operate the macerator discharge pump, move the Y-valve handle to the macerator pump-out
position, open the ball valve at the overboard discharge thru hull fitting. Then activate the macerator
switch until the tank is emptied. The ball valve and the macerator switch are located in the bilge near
the Y-valve below the aft berth. Release the switch and close the discharge ball valve when
pumping is complete.
Note: The macerator discharge pump can only be run dry for ten seconds. Allowing the
macerator pump to run after the holding tank is empty will cause damage to the
pump.
Maintenance
The head should be cleaned and inspected for leaks regularly. Periodically, remove the covers from
the holding tank vent and clean the vent of any debris. Be sure the cover is replaced securely after
cleaning. The cover helps prevent foreign matter from contaminating the vent system. If the vent
cover is damaged or lost, it should be replaced as soon as possible.
The holding tank should be pumped out and flushed as needed. Periodically add chemical to the
head and holding tank to help control odor and to chemically break down the waste. The macerator
pump should be sprayed with a metal protector periodically to reduce corrosion. See the head
manufacturer owner’s manual for additional operating and maintenance information.
THE HEAD SYSTEM MUST BE PROPERLY WINTERIZED BEFORE WINTER LAY-UP. SEE
SECTION ON WINTERIZING.
12.2 Refrigerator (AC - DC)
A dual voltage refrigerator is supplied as standard equipment. This unit will operate on 110-volt
AC or 12-volt DC power. The refrigerator switches to 12-volt DC automatically when the AC
power is disconnected and the refrigerator breaker is activated on the cabin DC panel. When 110-
volt AC current is provided by the refrigerator circuit breaker on the 110-volt panel, the refrigerator
automatically switches to AC power.
