INTERNAL SYSTEMS SECTION 4
5. The fresh water system is primed when all air is purged from the system’s
pipes and hoses. 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 (the washdowns
supply only cold water). 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 tank to replace that which was used in the
previous step. Refer to Section 4 Filling the Water Tank.
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.
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 Section 4 - Pressurizing and Priming the Water System.
Water Heater
To operate the water heater:
1. Fill, pressurize and prime the fresh water system. This automatically fills the
water heater.
2. Supply AC power to your boat. Refer to Section 3 - Shore Power or
Generator Power to do this.
3. On the AC Control Center, switch the Water Heater circuit breaker “ON.”
4. Refer to the OEM information for details on operating the 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 Section 4 - Filling the Water Tank and
Pressurizing and Priming the Water System before turning on the
water heater.
A Tip From Carver!
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.
