TYPICAL A/C INSPECTION TIPS
Seawater Strainer
The air conditioner
seawater strainer locat-
ed in the engine room
should be cleaned pe-
riodically of debris
which can inhibit or
stop the fresh seawa-
ter supply.
Always turn the sea-
cock to the off posi-
tion (90 degrees to the
hose fitting) before
cleaning a seawater
strainer. Remove the basket by turning the plastic cap in
a counterclockwise direction. Set the cap and the O ring
aside. Pull the basket from the unit, rinse with water, air
dry and reinstall. Sediment at the bottom can be removed
by just turning the plug in a counterclockwise direction.
Set the plug and O ring aside. Place a container under
the strainer to catch the sediment. Coat the O rings with
waterproof grease containing a silicone or te
fl
on base.
Reinstall O rings along with the plug and plastic cap. Turn
on the seacock and check for leaks.
Return Air Filters
Once a month check the return air
fi
lter located on the
face of the evaporator. To clean rinse with fresh water, air
dry and reinstall.

Drain Pans
As noted on an earlier page the AC evaporator/condenser
units feature a 2” deep drain pan connected by a hose
that runs to a sump pump and eventually exits overboard.
Periodically just like your home AC, the pan needs to be
rinsed clean of debris and possible mold.
You can use a purchased product made speci
fi
cally for
cleaning AC units. Disconnect the outlet hose from the
AC pan and install a made up hose (5/8” ) that will catch
the used solution to
fi
ll a small container. Dispose of the
container in accordance with federal, state and local regu-
lations. Pour the solution into the pan and allow time for
it to drain. Reconnect the original drain pan hose when
fi
nished.
Condenser Coil Cleaning
Periodically the condenser coils are recommended to be
cleaned. This procedure should be done by a professional
since an acid solution must be used.
POSSIBLE PROBLEMS/SOLUTIONS (A/C )
1. No or little water is noticed at the thru-
hull
fi
ttings and a HPF shows on the dis-
play which means the high pressure switch
is open.
The strainer or intake hose may be
clogged, seacock may be closed or a hose
may be collapsed or kinked. Check AC pump breaker to
verify pump operation.
2. Air conditioner will not start. Ensure the proper AC
breaker is actuated on the ship’s main control panel.
3. No cooling or heating. Lower or raise set point on ther-
mostat control to offset set point being satis
fi
ed. Check
for obstructed seawater
fl
ow. Remove discharge side of
pump hose to purge air (air-lock). Seawater temperature
too high for cooling and too low for heating.
4. Fan coil is iced. Raise or lower control set point. Clean
return air
fi
lter. Switch AC to heat until ice melts or as a
last resort use a hair dryer to melt ice as needed.
