4.0 Internal Systems
4.1 Air Conditioning System
For the air conditioning system to operate it needs a source of AC power
(supplied by either a shore power source or the generator) and a supply of
seawater (either salt or fresh).
The air conditioning system consists of four air conditioning units:
• A unit located behind the port aft bulkhead of the salon to cool the
salon.
• A unit located behind the port amidships bulkhead of the salon to cool
the galley, dinette and guest (port) head.
• A unit located behind the aft bulkhead in the guest stateroom to cool
the guest and third staterooms.
• A unit located beneath the master stateroom berth to cool the master
stateroom and master (starboard) head.
NOTE: Since the air conditioning condensation drains into the sump, make
sure the Auto Sump circuit breaker on the Safety Breaker Panel is “ON”
whenever the air conditioning system is operating.
4.1.1 Producing Heat
The air conditioning system can produce heat when it is operated in reverse
cycle mode. Reverse cycle operation, however, is affected by the tempera-
ture of the seawater. As seawater temperature decreases so does the air
conditioning system’s ability to produce warm air. Carver recommends that
the air conditioning system not be operated in reverse cycle mode when the
seawater temperature is below 40 degrees F.
4.1.2 Powering the Air Conditioning
1. Make sure the air conditioning seacock is closed. Remove and clean the
air conditioning system’s seawater strainer. The strainer prevents
debris in the seawater from entering the air conditioning pump. The
seacock, strainer, and pump are located in the engine room on the
forward centerline. Refer to the “Engine Room” portion of Section 9
for the exact location of the seacock, strainer, and pump.
2. Reinstall the seawater strainer. If the strainer leaks when the air
conditioning seacock is opened, close the seacock, then check the
strainer for correct installation.
