Hunter 31 • Water Systems
9.3
Refill with potable water and purge the plumbing of all
sanitizing solution.
9.2 Pumps
On board your boat there are both fresh water and raw
water pumps that control the flow of water to the related
components. These are electrically powered pumps .
Some of the features of these pumps are:
•Smooth Flow
• Self-Priming up to 10 feet (3m)
• Dry running capability
• Soft noise absorbing mounts
• Snap-fit port fittings
• Built-in bypass — less pulsation
• Reduces need for accumulator tank
• Corrosion resistant materials
Remember to read your OEM manuals for complete informa-
tion, as well as safety warnings, or notices.
9.2.1 Fresh Water Pump
The fresh water pump supplies water to the system
under pressure when the potable water supply is not
connected.
The FRESH WATER PUMP breaker switch is on the DC
side of the MDP. When the breaker is switched to ON,
the pumps will run until the hot and cold water systems
are pressurized. An automatic pressure switch shuts the
pumps off until the pressure drops to a preset level (for
example, a pressure drop caused by opening a faucet).
The pumps will then run again until the system is pressur-
ized and turn itself off. The pumps have a built-in check
valve to prevent backflow through the pumps.
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.
9.2.2 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.
9.2.2.1 To operate the air conditioner:
Refer to Chapter 8 AC Electric for air conditioner operat-
ing.
9.2.3 Toilet Water Supply
The toilet aboard your boat is supplied with flushing water
from the fresh water system (Electric toilet option only).
Standard toilet 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.
