12.3 Cabin Air Conditioner (Optional)
The cabin air conditioner operates on 12 volt DC
power. The unit cools only and will not function
as a heating unit.
You should always keep the cabin door closed
when operating the air conditioner. If the cabin
door is left open, it could cause the air conditioner
unit to run continuously and not cycle enough to
defrost the coiling condenser. This could cause
the coils to develop enough ice to reduce the unit’s
ability to cool the boat. With DC powered units,
leaving the cabin door open will significantly re
-
duce the available operating time while operating
the air conditioning on battery power.
The air conditioner is located under the berth in
the storage compartment. The unit creates con-
densation that drips into the pan at the base of
the unit. A hose attached to the pan drains the
water to the forward bilge and where it is pumped
out by the forward bilge pump. You should moni-
tor the operation of the bilge pump and make
sure it is operating properly whenever the cabin
air conditioner is activated. The air conditioner
can produce enough condensation to flood the
forward bilge and cabin sole if it is allowed to
run for extended periods without the bilge pump
operating properly.
It is normal for some water to be in the pan
whenever the air conditioner has been used. The
condensation pan should be checked periodically
to make sure it is draining properly. The drain
hoses, condensation pan and sump should be
flushed clean if they become restricted by mold
or debris.
The intake line for the seawater pump in the stern
bilge is equipped with a sea strainer that must be
checked for debris frequently and cleaned as nec-
essary. Refer to the Raw Water System chapter
for information on the air conditioning pump and
cleaning the sea strainers.
You should also refer to the air conditioner owner’s
manual for additional operating and maintenance
instructions.
Air conditioners use surface water as a cooling me-
dium. The boat must be in the water and the raw
water supply system must be properly activated
prior to use. Operation without proper cooling
could cause the air conditioning unit to shut down
and could cause system damage. Always check
Typical Cabin Air Conditioning Control Panel
for proper water flow out of the air conditioning
pump discharge thru-hull when the air conditioner
is operating.
12 Volt DC Air Conditioner Operation
The 12 volt DC air conditioning unit is activated
and protected by the Air Cond circuit breaker in
the DC breaker panel. It draws 12 volt DC current
from the house battery bank. The air conditioning
unit draws a significant amount of current (approx
30 amps) while operating. To avoid draining the
house batteries when operating the system at
dockside, make sure the 120 volt AC system is
connected to shore power and the battery charger
is activated to maintain the batteries.
When operating the system away from the dock,
the voltage in the house battery bank must be
monitored closely to avoid draining the batteries
when the engines are not running. If the house
batteries are in good condition and no other DC
equipment is operating, the DC air conditioner
can typically operate approximately 3 to 5 hours
before the batteries become drained. If the ste-
reo, cabin and/or cockpit lights, electronics or
other DC electrical equipment is being used, the
operating time available for the air conditioner will
be significantly less.
While underway at cruise speed, the engine
charging systems will provide enough current to
maintain the batteries with the DC air conditioner
operating. The engines will not provide enough
current at idle or trolling speeds to maintain the
batteries with the air conditioner operating, par-
ticularly with the stereo and electronics activated.
