House Battery Bank & Switch
The HOUSE BATTERY BANK provides power for all DC systems, except the engines and automatic bilge
pumps. When disconnected from shore power, all 12-volt devices drain the HOUSE battery. Use devices as
needed.
When a battery bank is being charged, the voltage will read from about 13.1 volts to 14.4 volts depending
upon state-of-charge of the battery bank. When the battery bank is at rest (that is, not being charged), the
voltmeter, located under the helm wheel, can give a rough indication of the state-of-charge of the battery
bank.

The
ENGINE/HOUSE/THRUSTER batteries are charged by the BATTERY CHARGER when connected to
shore power. Ensure the Battery Charger and Inverter circuit breakers at the electrical panel are ON. The
GENERATOR will also charge the batteries.

Battery Parallel Switch
Should the ENGINE battery be insufficiently charged to start the engine, the HOUSE/THRUSTER batteries
may be momentarily connected to provide a boost. Turn the BATTERY PARALLEL SWITCH located in
the port side lazerette to the PARALLEL position. Return the BATTERY PARRALEL SWITCH to the
“off” position after the engine starts.
SANITATION SYSTEM
Marine Toilet
It is important that every member of the crew be informed on the proper use of the MARINE TOILET. The
valves, openings, and pumps are small and may clog easily. If the toilet clogs, it is YOUR
RESONSIBILITY!
Always pump the head for children, so you can make sure nothing foreign is being flushed.
Caution
–
Never
put paper towels, tampons, Kleenex, sanitary napkins, household toilet paper, or food into
the marine toilet. Use only the special dissolving marine toilet tissue provided by Ship Harbor Yacht
Charters.
ZUMA has a 40-gallon holding tank, and it will need to be emptied approximately every two days. The tank
level is displayed on the toilet flush panel. (Green = empty, Orange = half full, Red = pump out) The lights
on the toilet panel will time out and go dark to save energy if they have not been used recently. If dark, touch
the button to activate.
