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 Tank” and “4.2.2
Pressurizing and Priming the Water System” before turning on the water
heater.
To operate the water heater:
1. Fill, pressurize and prime the fresh water system. This automati-
cally fills the water heater.
2. On the AC Control Center, switch the Shore #1 Main circuit breaker
“ON,” then switch the Water Heater circuit breaker “ON.”
3. Refer to the OEM information for details on operating the water
heater.
4.2.3.2 Shower and Sinks
Your boat has a shower and sink in the head, and a sink in the galley.
Used (grey) water from the galley sink flows directly overboard, unless
the optional grey water holding system is installed. Grey water from the
head sink and shower drains into a sump. Because the sump is located
below the boat’s waterline, a pump is needed to drain the sump and
