4.2.2 Pressurizing and Priming the Water System
Perform the following ONLY after the fresh water tanks are full.
1. Turn the “house” battery master disconnect switch to the “ON” posi-
tion.
2. On the Safety Breaker Panel, make sure the Auto Sump circuit breaker
is “ON,” then switch the Main - One circuit breaker “ON.”
3. Partially open all cold water faucets, including the faucets for the
transom hand shower and bow and transom fresh water washdowns.
4. On the DC Control Center, switch the Systems DC Main circuit breaker
“ON,” then switch the Pressure Water Pump circuit breaker ON.” This
activates the boat’s pressure water pump, which pressurizes the water
system. The pump is located in the engine room on the forward
centerline. Refer to the “Engine Room” portion of Section 9 for the
exact location of the water pump.

If your boat will be left unattended for at least a few days, switch the Pressure
Water Pump circuit breaker “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 frequently, it could discharge your batteries.
5. 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.
6. Add water to the fresh water tanks to replace that which was used in
the previous step. Refer to “Filling the Water Tanks . ”
When water pressure within the system increases to a predetermined point,
the pressure water pump automatically shuts off. Priming the system also
fills and maintains the water level within the water heater.
4.2.3 Using the Water System
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 system, simply open a faucet to receive fresh water. As you draw
water from the system, the pressure in the system decreases. When the
