6.1 FRESH WATER SYSTEM

The fresh water system consists of 4 tanks of 330 liters each, for a total capacity of 1320 liters, located under the guest’s cabin.
The following connections are installed:

• Water inlet
  It is located on the deck on the left side walkway inside a locker.
• Fresh water tank vent
  Located on the port side.
• Fresh water suction
  It supplies water to the autoclave pump that keeps the entire fresh water circuit under pressure. On the pump line there is a filter that removes possible water impurities. The pump to operate must be supplied by the magneto-thermal switch located on the main electrical panel.
• Tank water level transducer
  It checks the fresh water level in the tank. The water level in the tank may be monitored through the control panel.
• Desalinated water inlet
  The tank can be filled not only from the water inlet, but also from the watermaker.

The yacht can be equipped with a water softener (optional).
The system can also be supplied from shore. The various equipment can be supplied without using the autoclave system in this way.

Your boat can be equipped with a UV steriliser and an active carbon filter.

The fresh water system is equipped with an autoclave pump with electronic regulator.

• Less use of batteries since the pump is activated only with high flow requests;
• The pump continuous operation, eliminating the connection and disconnection phases;
• The device stopping the pump in case of water lack is installed on both pumps;
• The pump start after reaching the minimum pressure value set.

The panel with warning lights displays the various operation stages:

• Power ON (green light - voltage);
• ON (yellow light - pump runs for some seconds and brings the system under pressure).

At user connection the system starts the pump automatically, this latter stops when the user disconnects, after resetting the system under pressure.
When faults occur, such as water leak of pipe clogging, the electronic regulator indicates the faults by means of “Failure” red light and stops the pump.
The system restarts either by pressing the red Restart button, or by handling on the magneto-thermal switch on main electrical panel (by cutting out/in the pump voltage supply).

CAUTION

Before refilling the fresh water tank, check that the water supplied by the shore fresh water system is drinkable.

CAUTION

The fresh water circuit, must be sanitized periodically by pouring in the case a specific disinfectant solution.
We recommend in any case that the water coming from the on-board system not be drunk.

CAUTION

On yacht equipped with direct connection to shore fresh water, the maximum operation pressure should not exceed 2.8 bar.
Notwithstanding the presence of a pressure limiter, check the pressure on the pressure gauge installed on board.
Disconnect the pipes for safety reasons, if yacht is left unattended.

CAUTION

Regularly inspect the fresh water and bilge circuits for leaks.
Repair any leaks by releasing the pressure in the system.

CAUTION

The pressure regulator at pumps output is set at the factory; do not modify.

CAUTION

The inlet plug is marked “WATER” to avoid accidental introduction of different liquids. To avoid damage to the system and tanks, we recommend replenishing by gravity and not by pressure.

WARNING

It is a good norm to optimise the use of water, especially if navigating at open sea!

CAUTION

In case of need, break or pollution of the tanks, they can be replaced.
Contact the RIVA After Sales & Service Department.

CAUTION

RIVA declines all liability for tampering made by third parties to equipment installed by the Shipyard itself.
These unauthorized manipulations, as well as in immediate cancellation of the warranty, can cause damage to the yacht itself and the people who are on board.
RIVA declines all liability for periodic maintenance activities not executed but planned by the Shipyard or by the Manufacturer of the devices or components, for which reference should be made to the consultation of the Technician Manuals.
