6. The fresh water system is primed when all air is
purged from the system's pipes. Monitor each sink
tap and shower head. When a steady stream of
water flows from the tap or shower head, close the
cold water faucet for that tap or shower head, then
open its hot water faucet. When a steady stream of
water again flows from the tap or shower head,
close the hot water faucet for that tap or shower
head. When you have done this for each sink tap
and shower head, the water system is primed.
When water pressure within the system increases to a
predetermined point, the pressure water pump auto-
matically shuts off. Priming the system also fills and
maintains the water level within the water heater.
The fresh water system is designed to operate in the
same manner as the water system in your home. After
filling, pressurizing and priming the fresh water sys-
tem, simply open a faucet to receive fresh water. As you
draw water from the system, the pressure in the system
decreases. When the pressure decreases to a predeter-
mined point, the pressure water pump automatically
turns on and increases the pressure. This ensures a
steady flow of water any time you open a faucet.
Sometimes a recently filled system or one that has not
been used for some time may need re-priming. This is
normal and is caused by an accumulation of air bubbles
at the pressure water pump. To re-prime the fresh
water system, repeat the steps in "Pressurizing and
Priming the Water System" .
Water Heater
Do not supply power to the water heater when it is
empty. Doing so may damage the unit’s heating ele-
ment and cause a fire. Fill, pressurize and prime the
fresh water system as described in "Filling the Water
Tanks" and "Pressurizing and Priming the Water
System" before turning on the water heater.

If your boat will be left unat-
tended for at least a few days,
switch the Pressure Water Pump
circuit breaker on the DC Control
Center "OFF". If this breaker is
left on, pressure in the fresh
water system may fall and cause
the water pressure pump to
engage. If this happens fre-
quently, it could discharge your
batteries.
