Water Systems
9.4
The fresh water washdown connection is located on the
transom.
Important: Operate the fresh water pumps only when there
is water in the tank. Running the pumps dry will damage the
diaphragm.
Note: If the pumps run from time to time even though no water
is being used, a leak in a water line is a likely cause. Check all
lines for leaks and repair immediately.
9.3.2 A/C Cooling Pump
Your boat may be equipped with the optional air condi-
tioner reverse cycle unit. This type of unit can heat or
cool your boat.
The Air Conditioning system is made up of a pickup valve
(or thru hull) (See Underwater Gear for its location), a sea
strainer, an A/C cooling pump, and the major compres-
sors and air handlers.
To find the A/C cooling pumps’ location refer to the
arrangement illustration at the end of this chapter or the
Mechanical Arrangement at the end of the Boating Safety
Chapter.
The A/C cooling pump receives sea water from the pick-
up strainer and pumps it through the A/C compressor to
cool the compressor.
See the AC Electric Section for an explanation of the
electrical controls of this system.
9.3.4.1 To operate the air conditioner:
1. Open the air conditioner seacock. The valve is open
when its handle is in line with the hose. The seacock is
located to the port side of the Lazarette area, aft of the
A/C pump, in the bilge.
2. Check the strainer. Clean if necessary to assure a
steady flow of water to the unit.
3. Set the thermostat to the temperature desired.
Important: Be sure to close air conditioner seacock
when the air conditioner is not in use. Refer to the man-
ufacturer’s owner’s manual furnished with the air con-
ditioner for more information regarding its operation.
9.3.3 Toilet water supply
The toilet aboard your boat is supplied with flushing water
from the fresh water system (Electric toilet option only).
Standard tiolet use raw water.
More information concerning the operation and main-
tenance of this system can be found in the Waste
and Sanitation chapter, Chapter 10 of your Operator’s
Manual.
9.4 Pickups and Strainers
There are various pickups and strainers installed
aboard your boat. Here we will discuss the pick-ups
and strainers associated with the water systems.
9.4.1 Pick-ups
Pick-ups, or through hulls are placed in various locations
in the hull of your boat. The intakes usually have a ball type
valve which controls the flow of raw sea water to the spe-
cific component, or system associated with the pick-up.
It is very important that you ensure that the intake
valve is open before using a raw water supplied sys-
tem. Failure to do so could damage or break down a
system or component.
9.4.2 Strainers
Your boat is equipped with strainers that strain the raw
water taken in the thru hulls or pickups for objects that
could damage the impeller or pump equipment. Strainers
are equipped with a screen or a filter inside that collect
objects taken in. They must be cleaned as part of routine

and the strainer
for the A/C sys-
tem. Note the
ball type valves.
When the handle
parallel to the
supply line then
it is in the open
position.
