6. Air conditioning

It is critical that the load is applied to the generator slowly. Air conditioning
units must be turned on a few minutes apart to avoid overloading the
generator.
The air conditioning units will operate when the vessel is plugged in to shore power or
when the generator is running. Each hull has its own individual air conditioning
control unit and there is one for the saloon.
Water from all three AC units drains to the shower drain sump boxes in the bilges and
as a result you may hear intermittent pump operation when running the air
conditioning. These are hardwired and no switches are needed for them to operate.
The air conditioning units should be turned on after the generator has been running
for 5 minutes (or once the boat is plugged into shore power) and the breakers should
be shut off before stopping the generator or unplugging from shore power.
Ensure the companionway and all hatches are closed; otherwise, the compressors will
freeze up.
Starting the air conditioning:
• Switch on the required units 5 minutes apart.
• Each of these units also has an individual control which allows users to alter the
settings for the individual units.
