Operation

 Each air conditioning unit installed requires its own dedicated circuit
breaker.
– If there is only one air conditioning 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 diagram, fig. 8, page 7)
– 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).
➤ Connect the air conditioning unit 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.
➤ Bond individually all pumps, metallic valves and fittings in the sea-
water circuit that are insulated from the air conditioning unit by PVC or
rubber hoses to the boat's bonding system.
This will help eliminate any possibility of corrosion due to stray cur-
rent.
