System Operation - Four winns V458 Owner's Manual

B. System Operation
When properly primed and activated, the pressur ized
water system can be used in the same man ner as
the water system in a home. An automatic pres sure
sensor in the water pump keeps the system pressur-
ized. Sim ply turn on the faucet and water will be
deliv ered. If the system has been recently filled, or
has not been used for an extend ed period of time,
air bubbles may accumu late at the pump and/or in
the waterlines. If this should happen, re-priming may
be necessary. Refer to the preceding subsection
regarding priming the system.
To obtain the most consistent mix ture of hot and cold
water, turn the cold water on full, then mix in hot water
until the desired temperature is ob tained. If water
pump cycling occurs, some minor varia tions in water
tempera ture can be expect ed.
Whenever the boat will be left unat tended for an
extended period, the FRESH WATER PUMP circuit
breaker switch should be turned to the OFF position.
This switch should also be turned OFF whenev er the
water tank is to remain empty for an extend ed period
of time.
C. Water Heating Systems
A water heater is a standard feature on the V458
models. The capacity of the water heater may be
found on our website at www.fourwinns.com. Refer to
Figure J5 and the locator drawing at the back of the
manual for the location of the water heater.
NOTICE
Water heater location may vary due to the
installation of optional equip ment.
The water heater utilizes 120 volt (230 volt on 50
Hertz models) power. The water heater breaker switch
is located on the cabin 240V AC cabin panel.
NOTICE
DO NOT supply 120 volt (230 volt) power to an
empty water heater. Damage to the heat er will
re sult immediately. The water system must be
filled and primed before attempting to use the
water heater.

Figure J5: Water Heater Location
On the V458 models the water heater incorporates a
heat exchanger. The heat ex changer allows the
engine coolant to quickly heat a portion of the fresh
water supply while the engines are operat ing. This
provides hot water at times when 120 volt power is
not avail able. Addi tional informa tion on heat exchang-
ers is discussed in the hot water heater manu-
facturer's manual. Please refer to Section H on
Electrical Systems for addi tion al information.
D. Using The Forward & Aft Showers
Turn on the shower by lifting up on the shower handle.
Rotate the shower handle position to obtain the
de sired tempera ture. The shower head is designed to
be hand-held. If desired the shower sprayer may be
removed from its holder position and used. This hand-
held feature allows for greater ease of use and
efficiency. When showering has been completed, turn
the shower handle to the off position and place the
shower head back onto its holder (if applicable). Note:
height of the shower holder for the forward head may
be adjusted for convenience.
When using the shower, draw the shower curtain
closed before using the shower. Dam age to the finish
can result if sur rounding walls and flooring are allowed
to become exces sively wet. Thor oughly dry these
areas after showering.
The water temper ature can vary during shower
use as the pressure pump cycles on and off.
