Battery Charger Control Panel & Meter in AC Panel
The wires that supply DC charging current to
the batteries are protected by internal fuses in
the battery chargers and external fuses, one for
each battery output wire near the batteries. The
external fuses protect the DC charging circuit from
the batteries to the charger. The internal fuses in
the chargers protect the DC charging circuit from
the charger to the batteries. Refer to the battery
charger owner’s manual for more information on
the features and operation of the battery charger.
The charge to the engine batteries can be moni-
tored by using the volt meters in the engine gauge
cluster, meters in the charger control panel on the
AC panel or the meters on each charger. To moni-
tor the engine start batteries with the volt meters
in the engine gauge cluster, activate the charger
and turn the engine battery switches on. Turn
the ignition switch for each engine to the “ON”
position (DO NOT START THE ENGINES) and read
the voltage on the volt meter for each engine. If
the batteries are in good condition and charging
properly, the volt meters will indicate between 12
and 14.5 volts. If the reading is below 12 volts,
then the battery is not accepting a charge or the
charger is not working properly. Always turn the
ignition switches off immediately after the moni
-
toring is complete when using the voltmeters in
the engine gauge cluster. The charge to the house
batteries is monitored using the meter in the AC
panel or on the charger.
HVAC Unit Cabin
Supplies electrical current to the air conditioner
compressor and control panel located in the cabin.
HVAC Unit Cockpit
Supplies electrical current to the cockpit air con-
ditioner compressor and control panel.
HVAC Pump
Supplies electrical current to the seawater pump
in the aft systems compartment that circulates
seawater through the air conditioning units. The
pump runs whenever an air conditioning unit is
operating.
Notice:
After a certain amount of time without water
flow, the air conditioning units will automati
-
cally power down. If this occurs, reset the
units and check for water flow out of the air
conditioning thru-hull. Refer to the air condi-
tioner owner’s manual for more information.
Freezer Plate
Supplies electrical current to the cooling unit for
the freezer plates in the fishboxes and coolers.
Temperature is controlled by a digital monitor
located in the AC panel. Freezer/fishbox tem
-
perature is displayed on the LED screen and but-
tons on the panel allow for the adjustment of the
temperature.
Accessory
Reserved for additional AC equipment.
Dometic Freezer Plater Controller
