plate label. A minimum of 12 AWG boat cable should be
used to supply power to the air conditioning unit and to
the seawater pump (see next paragraph). All connections
to the terminal strip shall be made with ring terminals
supplied with the Cool Mate kit.
Turn off AC (alternating
current) power supply circuit breaker before opening
electrical box and accessing the terminal strip.
Each air conditioning unit installed requires its own
dedicated circuit breaker. If there is only one air condi-
tioning unit installed, the seawater pump does not
require a circuit breaker; the wiring from the seawater
pump is connected to the terminal strip on the unit. (See
wiring diagrams, Figures 7-9, at the back of this manual.)
A minimum of 12 AWG boat cable should be used to
extend the wires on the pump, if necessary, using the
butt slices included with the kit. If two or more air
conditioning units use the same seawater pump, the
pump wires will be connected to a pump relay panel
(PRP) which in turn has its own dedicated circuit breaker
(see the wiring diagram furnished with the PRP). Any
electrical connections in the bilge below the waterline
should use heat shrink type butt splices.
The air conditioning unit must be connected to the boat's
bonding system to prevent corrosion due to stray electrical
current. Ensure that the AC ground of the air conditioning
unit is properly connected to the AC ground of the boat.
Within the boat itself, ensure that the AC ground bus is
connected to the DC ground bus at exactly one place (no
more, no less). All pumps, metallic valves and fittings in
the seawater circuit that are isolated from the air condi-
tioning unit by PVC or rubber hoses must be individually
bonded to the boat's bonding system also. This will help
eliminate any possibility of corrosion due to stray current.
Note: Failure to properly ground and bond the system will
void the warranty!
Electrical Connections, Grounding &
Bonding for DC Powered Cuddy dc
All Cuddy dc units are connected by polarized plugs to
the Dedicated Power Module DPM, pump, and control
(available separately or in kit). These plugs are config-
ured unique to each component. Wiring diagrams and
schematics are provided in this manual (see Figure 10 at
the back of this manual). A 60 amp circuit breaker or
fuse should be installed at the positive side of the
battery to protect the wires. Any electrical connections in
the bilge below the waterline should be heat shrink
type.
Turn off DC power supply circuit breaker before
making connections.
The air conditioning unit and its components must be
connected to the boat’s bonding system to prevent
corrosion due to stray electrical current. There is a
bonding ground stud on the Dedicated Power Module.
This stud must be connected to the vessel’s bonding
stud, which is typically on the engine block. This connec-
tion must be made per ABYC specifications. All pumps,
metallic valves and fittings in the seawater circuit that
are isolated from the air conditioning unit by PVC or
rubber hoses must be individually bonded to the boat’s
bonding system also. This will help eliminate any possi-
bility of corrosion due to stray current.
Note: Failure to properly ground and bond the system
will void the warranty!
Electrical System and Wiring for
DC Powered Cuddy dc
Dometic recommends a separate set of batteries dedi-
cated for the Cuddy dc air conditioning system. Deep
cycle AGM or Gel Cell batteries are the best for this
application. If need be, please contact your Dometic
dealer for assistance in sizing batteries.
The Cuddy dc kit contains the Dedicated Power Module
(DPM). The DPM is meant to be used for the Cuddy dc
system only and is sized to do so (see Figure 11 at the
back of this manual for DPM specifications).
When connecting the DPM to the batteries, maintain
correct wire size as shown in the DC Wire Sizing Table
(see Figure 12 at the back of this manual), keep wire
runs as short as possible, and with as few intermediate
connections as possible, to avoid unnecessary resis-
tance or voltage drop. See wiring diagram Figure 10 for
location of customer-installed 60 amp fuse. Use an
ignition protected fuse holder if installed in the engine
compartment or in any area with flammable or com-
pressed gasses or liquids (see the Safety Considerations
section of this manual for more information). A standard
ABYC approved battery disconnect switch is also
recommended and should be used any time the system
needs servicing. Do not forget to maintain proper color
coding, (red = positive, black = negative) to aid in future
electrical troubleshooting. If the wires are incorrectly
connected (positive and negative reversed), the air
conditioning unit will not start and the DPM will be
damaged.
The DPM is wired to the FAN setting on the two-knob
switch assembly and is energized only when the Cuddy
dc is running (see the Operation section of this manual).
For DC wire sizing, see Figure 12 at the back of this
manual.
As batteries age, their peak voltage lowers and they
discharge quicker. This, of course, can affect the air
conditioner performance as well as other DC devices.
The battery condition should be maintained and moni-
tored regularly and weak batteries should be replaced. A
battery isolator, combiner or selector switch will allow
simultaneous charging while preventing the discharge of
a fully charged battery into a depleted one.
