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 two air conditioning units:
• A unit located in a cabinet next to the companionway to the stateroom level
to cool the salon, galley, and dinette.
• A unit located beneath the master stateroom berth to cool the master
stateroom, guest stateroom, and head.
The air conditioning system can produce heat when it is operated in reverse
cycle mode. Reverse cycle operation, however, is affected by the temperature
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°F.
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 system. The seacock, strainer, and
pump are located beneath a hatch in the cockpit. Refer to Section 9 - Interior
Hatches for the exact location of the strainer.
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.
3. Open the A/C seacock to supply seawater to the A/C pump.
4. Supply AC power to your boat. Refer to Section 3 - Shore Power or
Section 3 - Generator Power to do this.
Because the forward stateroom air conditioning unit's condensation
drains into the sump, the Auto Sump - Forward circuit breaker on the
Safety Breaker Panel must be "ON" whenever the air conditioning system
is operating.
5. On the Safety Breaker Panel, switch the Auto Sump - Forward circuit
breaker "ON."
Do not run the air conditioning system's water pump when the seacock
that supplies seawater to the system is closed. Operating the pump with
no seawater can damage it.
6. On the AC Control Center, switch the Shore #2 Main circuit breaker "ON,"
then switch the A/C System Water Pump circuit breaker "ON."
7. Switch the desired A/C Unit circuit breakers "ON."
