9.2.3 Air Conditioning Cooling Water
The air conditioning compressors use raw seawater as
cooling water. The intake for this system is on the star-
borad side of the engine forward in the engine compart-
ment. This system consists of an intake, a strainer and
a pump. Refer to page 9.10 for a more detailed layout.
The used water is then discharged through the air con-
ditioning through hull.
9.2.4 Raw Water Washdown
Located in the anchor locker forward in your boat is
the raw water washdown. This system consists of a pie
eye in the anchor locker with a retractable hose inside
equipped with a valve. This system makes an ease of
washing the anchor components when retracted.
The raw water pump provides water under pressure
for forward washdown. Figure 9.6 is a view of the raw
water pump, intake and strainer. The pump cycles on
and off as needed to maintain water pressure within a
preset range.
When the pressure drops to a low set point, the pump
turns on and runs until the pressure reaches the high
set point. If the outlet valve is completely open, the
pump runs continuously. If it is partially open, the pump
cycles on and off.
The raw water pump is located on forward port side
engine room bulkhead.
To use the raw water washdown:
1. Ensure the breaker on the DC Distribution Panel is
on.
2. Wait for the system to build up pressure, which will
be noted by the pump shutting off.
3. Turn on the valve and use.
