If your boat will be left unattended 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 frequently, it could discharge your batteries.
5. The fresh water system is primed when all air is purged from the
system’s pipes and hoses. Monitor each sink tap, shower head and
washdown. When a steady stream of cold water flows from the tap,
shower head or washdown, close its cold water faucet, then open its
hot water faucet (the washdowns supply only cold water). When a
steady stream of water again flows from the tap or shower head,
close its hot water faucet. When you have done this for each sink tap,
shower head and washdown, 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 4.2.1 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 pressure decreases to a predetermined 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 4.2.2 Pressurizing and Prim-
ing the Water System.
4.2.3.1 Water Heater
Do not supply power to the water heater when it is empty. Doing so may
damage the unit’s heating element. Fill, pressurize and prime the fresh
water system as described in “4.2.1 Filling the Water Tanks” and “4.2.2
Pressurizing and Priming the Water System” before turning on the water
heater.
