Water Heater
The water heater is located below the pas-
sage leading to mid-berth. All heaters have
an AC element that is thermostatically con-
trolled at the heater and activated by a cir-
cuit breaker located in the AC panel. A high
pressure relief valve protects the system
from excessive pressure. Make sure all air is
purged from the water heater and lines
before activating the water heater breaker.
Refer to the water heater manual for addi-
tional information.
Shore Water Connection
The shore water connection allows the direct
connection of the water system to a shore
side water supply. This provides the system
with a constant supply of fresh water and
minimizes the pressure pump operation. A
female inlet fitting is mounted in the cockpit.
To use shore water, connect a hose from the
shore water faucet to the shore water fitting
on the boat, then turn on the shore water.
The pressure pump will not run and the
water in water tank of the boat will not be
used. Also, the water tank will not be filled by
connecting to shore water.
5.2 Raw Water Washdown
The raw water washdown system pump is
supplied by hoses connected to a ball valve
and a thru-hull fitting located in the bilge.
Operation
Make sure the ball valve is open before
attempting to operate the raw water wash-
down system. The pump is activated by the
washdown switch located on the helm.
When activated, the pressure switch will
automatically control the pump. As pressure
builds in the washdown hose, the pump will
shut off. When the washdown hose is in use
and the pressure drops, the pump will turn
on. Turn the switch off when the washdown
is not in use. The raw water washdown is
equipped with a sea strainer on the intake
side of the pump, located in the aft bilge;
check it frequently and clean as necessary.
Priming the System
Open the ball valve and hose connector, and
activate the pressure pump. Run the pump
until all air is purged from the system. Close
the thru-hull ball valve before the boat is
hauled from the water to eliminate an air
lock in the system. It may be necessary to
! CAUTION

filled and primed, damage to the
heater will result.
! CAUTION
DO NOT change or modify the shore
water inlet connector without contact-

a modification can damage the fresh
water system.
