To obtain the most consistent mixture of hot and cold
water, turn the cold water on full, then mix in hot water
until the desired temperature is obtained. If water
pump cycling occurs, some minor variations in water
temperature can be expected.
To remove excessive chlorine taste or odor which
might remain in the system, prepare a solution of one
quart vinegar to five gallons water and allow this
solution to agitate in the tank for several days during
boating. Then drain tank and refill with fresh water.
Whenever the boat will be left unattended for an

installation of optional equipment.
A.   Priming the System
After filling the water tank, open all faucets partially.
Activate the FRESH WATER circuit breaker switch
on the cabin AC/DC panel to supply the system with
water. Let the pump run until water comes out of the
galley faucet, head faucet and transom shower.
The water heater utilizes 120 volt (220 volt on 50
Hertz models) power. The water heater breaker switch
is located on the cabin 120 Volt AC panel.
After all the air has been purged from the system and
a steady flow of water is coming from each outlet, turn
off the faucets one by one. Begin with the cold water
faucets and continue until all faucets are shut off. As
the pressure builds, the pump will automatically shut
off at 60 psi. Refer to Section H-5 - 12 Volt Electrical
Equipment and the manufacturer’s literature included
in the owner’s packet for additional information.
DO NOT supply 120 volt power to an empty
water heater. Damage to the heater will result
immediately. The water system must be filled
and primed before attempting to use the water

B.   System Operation
When properly primed and activated, the pressurized
water system can be used in the same manner as
the water system in a home. An automatic pressure
sensor in the water pump keeps the system pressur-
ized. Simply turn on the faucet and water will be
delivered. If the system has been recently filled, or
has not been used for an extended period of time,
air bubbles may accumulate at the pump and/or in
the waterlines. If this should happen, re-priming may
