Self-Contained Air Conditioning System 

Disposal

All conditioning units have a terminal strip, labeled 
for proper connections, inside the electric box. The 
wiring diagram inside the electric box supersedes ABYC 
standards. Use the correct size circuit breaker to protect 
the system as specified by the air conditioning units data 
plate label. A minimum of 12 AWG boat cable should 
be used to supply power to the air conditioning unit and 
the seawater pump. Make all connections using ring or 
captive fork terminals.

Observe the following when making electrical 
connections:

•  Alternating current (AC) grounding must be 

connected to the ground terminal (GRND) at the AC 
power input terminal block.

•  Connections between the vessel’s AC system 

grounding conductor and the vessel’s direct current 
(DC) negative or bonding system should be made 
as part of the vessel’s wiring. When servicing or 
replacing existing equipment that contains a chassis-
mounted ground stud, check the vessel’s wiring for 
these connections.

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. 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.
