b. Close the water relief valve.
4. Partially open all cold water faucets including sinks, showers, and transom hand shower.
5. Switch ON the PRESSURE WATER PUMP circuit breaker, located on the DC control center. Turning the pressure
water pump breaker on activates the pressure water pump and pressurizes the water system. The freshwater
system is fully primed when all the air is purged from the system’s pipes and hoses.
6. Monitor each sink tap and shower head starting from the transom.
7. Once a steady stream of water ows from the tap or shower head, close the cold water faucet for the tap or shower
head.
8. Open all hot water faucets.
9. The water system is fully primed when all hot and cold water faucets have a steady ow of water.
10. Add water to the freshwater tank to replace the water used in previous steps.
11. The pressure water pump automatically shuts off when water pressure within the system increases to the
manufacturer’s design level.
USING THE WATER SYSTEM
The freshwater system is designed to operate the same as an in-home water system. Open any faucet to receive fresh
water after lling, pressurizing and priming the freshwater system. The pressure in the system decreases as water draws
from the system. The pressure water pump automatically turns on and increases the pressure when pressure within the
system decreases. The automated system ensures a steady ow of water any time a faucet is opened.
Occasionally, re-priming may be necessary for a recently lled system or a system that has not been used for a while.
Re-priming is normal, and is caused by an accumulation of air bubbles at the pressure water pump. To re-prime the
freshwater system, repeat the procedure in PRESSURIZING AND PRIMING THE WATER SYSTEM on page 63.
A TIP FROM CARVER!
To obtain a consistent shower temperature, turn on the cold water faucet fully, and then slowly turn on the hot water faucet
until the water owing from the shower head is at the desired temperature. This method keeps the pressure water pump
running and eliminates widely uctuating temperatures.
OPERATING THE WATER HEATER
1. Fill, pressurize and prime the freshwater system as explained in PRESSURIZING AND PRIMING THE WATER SYSTEM
on page 63. This process automatically lls the water heater.
2. Supply AC power to the yacht. See AC POWER SOURCES on page 43 for instruction.
3. On the AC control center:
a. Switch ON the two MAIN circuit breakers.
b. Switch ON the WATER HEATER circuit breaker.
4. For more information, refer to the Original Equipment Manufacturer (OEM) information for details on operating the
water heater.
NOTICE: Never supply power to the water heater while empty; damage may occur to the heating element. Fill,
pressurize and prime the freshwater system before turning on the water heater, as described in FILLING THE
WATER TANK on page 63 and PRESSURIZING AND PRIMING THE WATER SYSTEM on page 63.
