WARNINGThe high temperature may cause the softening of the pipes and the consequent loosening of joints. Then verify the tightness, especially for those positioned in the vicinity of heat sources.
In case of maintenance or of need, it is possible to cut out parts of the system or single uses, without involving the operation of the general system, by handling on the cocks installed on the main manifolds.
WARNINGThe high temperature may cause the softening of the pipes and the consequent loosening of joints. Then verify the tightness, especially for those positioned in the vicinity of heat sources.
WARNINGTo stop a failure in the hot water circuit can act on the valves in the inlet to the water heater.
WARNINGAt least every month, providing a completely empty the fresh water tank and rinse a few times with clean fresh water. This in order to completely renew the water present in the deposits and at the same time wash the tanks themselves.
Remove the caps, check, clean, disinfect and restore the closures taking care to check the O-ring state.
1 At least once a year to make an internal tank cleaning.
Pour periodically inside the tanks, of the filler loading of a specific disinfectant in the doses recommended by the manufacturer, in order to avoid the formation of colonies of bacteria in the system.
For further information, refer to the specific manuals of the various equipment installed on board and the technical schemes provided in part by the shipyard.
WARNINGDuring winter, if you do not use the yacht, drain the water heaters to prevent cracks due to freezing.
CAUTIONThe boarding cap has the words “WATER” to prevent the accidental introduction of different liquids.
To avoid damage to the system and to the tanks, it is recommended to supply to fall and not a pressure.
CAUTIONThe fresh water circuit, and in particular the tanks, must be periodically sanitized pouring in embarking a specific disinfectant solution. It is advisable not to drink the water coming from the board.
CAUTIONCater periodically inspect the fresh water circuit of the bilges and to detect the possible presence of leaks.
Repairing leaks by removing the system under pressure in order to avoid furnishing and electrical equipment damage.
WARNINGIt is advisable to optimise the use of water, especially if you are navigating offshore!
CAUTIONIn case you do not have hot water, due to system fresh water emptying, switch off the water heater in order to avoid damage to the resistance.
| Component | Maintenance | Notes and precautions |
| Fresh water tank | Cleaning and check | At least every month, drain the fresh water tanks completely and rinse them a couple of times with clean fresh water. This in order to change completely the water stowed in the storing tank and at the same time to wash them too. Check, clean, disinfect and restore the closures and verify the O-ring condition. Periodically pour a specific disinfectant, in the quantity recommended by the Manufacturer, into the tank, through the intake filler, in order to prevent the formation of bacteria in the system. |
| Fresh water system | Check | In case of need or of maintenance, by acting on the valves installed on the distribution manifolds, it is possible to cut out parts of the system or single uses, without involving the operation of the general system. Check if along the hydraulic circuit, where possible, are present leaks due to the damage of piping. The main manifolds are located on the bilge corresponding to starboard and port crew cabin, and in the technical room. WARNINGIn case of need, break or pollution of the tank, it can be replaced. CAUTIONThe fresh water circuit, and particularly the tank, must be sanitized periodically by pouring in the case a specific disinfectant solution. |
| Electric pumps | Cleaning and check | Periodically check for the presence of leaks. Before carrying out maintenance on the pumps, prevent their accidental priming. Check daily that the expansion tank located downstream the electric pumps shows the correct pressure in the air cushion. Regularly check that fittings are tightly closed and free from corrosion. Check the conditions and the cleanliness of the pumps and of the expansion tank; if necessary, clean with well diluted detergent and dry accurately (see Specific Manual).  DANGERBefore carrying out maintenance on the pumps, prevent their accidental priming. |
| Electric water heaters | Cleaning and check | WARNING During winter, if you do not use the yacht, drain all the circuits where there is fresh water to prevent cracks due to freezing. CAUTIONIf warm water is not available, because of the fresh water circuit discharge, switch off the water heater to prevent damaging it resistor. |
