Electrical

Prior to making any decisions concerning the electrical source, please refer to your specifications

sheet on your boat and note the total amperage draw to operate the necessary air conditioning

system. With this information at hand, now consider the following possibilities:

1. Generally speaking most boats come standard with a single 30 amp shore line connection.

2. Unless the boat is equipped with such electrical items that require substantial electrical

supply (such as electric stove, water heater, refrigerator/freezer, etc...) the air conditioning

system may be wired to this existing 30 amp, 115 volt service, as long as the total

requirement does not exceed 30 amp. In such cases where there are these accessories that

draw high amperage, it is recommended that an additional 30 amp shore line service be

installed to handle the additional electrical load that the air conditioning system will

require.

All Cabin Comfort Series units are supplied with a 5 position terminal strip mounted on top of

the electrical box. The electrical supply, ground wires, and pump circuits are all connected at

this terminal strip. Electrical supply to the unit is connected to the terminals marked POWER

(115 or 230 Volt). The wiring from the seawater pump is connected to the terminals marked

PUMP.

NOTE: If you use two or more units on the same seawater pump, the pump wires will be

connected to the pump relay panel to energize the pump. You will need another source of 115 or

230 volt power to run the pump. The pump relay panel should have its own circuit breaker.

Please see the wiring diagram furnished with the relay panel in this instance.

Note: Field wiring must comply with ABYC electrical codes. Power to the unit must be

within the operating voltage range indicated on the nameplate. Properly sized fuses or

HACR circuit breakers must be installed for branch circuit protection. See equipment

rating plate for maximum size.
