at the pump and the system may have to be
re-primed.
Whenever the boat is left unattended, turn
the FRESH WATER PUMP switch OFF.
CAUTION
!
DO NOT allow the fresh water pump
to run dry; damage to the pump can
occur. The fresh water pump works on
demand and WILL NOT shut off when
the tank is empty. Turn the water pump
switch OFF when the system is not in
use. Operating any pump from a low-
charged battery can lead to a pump
failure. Keep the batteries properly
charged. The fresh water system must
be properly winterized prior to winter
lay-up. Refer to winterizing directions
in section 12, Seasonal Maintenance.
Sink and Shower Operation
To use the sinks or shower, switch ON the
FRESH WATER PUMP switch on the DC dis -
tribution panel. Some minor variations in the
water temperature and pressure may occur
as the pump cycles.
The sinks drain overboard. Shower water
drains to a sump pump system located in the
bilge below the cabin floor. An automatic float
switch in the shower sump controls the pump.
After showering, let the cold water flow for a
period of time to flush the drainage system
of soap residue. The shower drain strainer
should be cleaned regularly and the sump
inspected periodically for accumulated debris
that needs to be removed.
Water Heater
The water heater is located outboard in the
port mechanical space. The water heater
uses an AC element that is thermostatically
controlled at the heater. A high pressure relief
valve protects the system from excessive
pressure.
Water heater (optional)
To use the water heater, the WATER HEATER
breaker on the AC distribution panel (installed
in the starboard cabin upper electrical cabi-
net) must be ON. Make sure all air is purged
from the water heater and lines before acti-
vating the water heater breaker. Refer to the
water heater manual for additional informa-
tion.
CAUTION
!
DO NOT turn on the water heater until
it is filled and primed; damage to the
heater will result.
CAUTION
!
DO NOT change or modify the shore
water inlet connector without contact-
ing Tiara Yachts Customer Relations
or your dealer. Modification to or use
of the wrong type of connector can
damage the fresh water system.
5.2 Freshwater System Com-
missioning
The freshwater system must be disinfected
before first use, and annually at the beginning
of each season. A clean, sanitized freshwater
system will greatly reduce the risk of develop-
ing coliform bacteria or other disease-causing
organisms (pathogens), and will help protect
the health of everyone onboard.
