Sunseeker 34 Metre Yacht

An external shore water supply can be connecteddirectly to fill both water storage tanks. Alternatively, a connection can be made directly to the ships water system. This option eliminates the need to use the vessels water pumps, since pressure is provided directly from the shore.Both connections will be fitted with a pressureregulator to protect the system components and also an in-line strainer to remove any debris.A Gianneschi Water Pressure Set comprising of:2 x ACB 331 Self-priming pumps – 400V/3/50- 60Hz – capacity (each) circa 90lt/min @ 5m head. A carbon filter shall be fitted to the outlet of thepressure setThe cold water circuit shall be arranged as a singlemain run (not a ring main) through the length of the yacht.2 x 200 litre hot water cylinders, each fitted with 3 x2kW immersion heaters. An expansion vessel of suitable size shall be also fitted in a location depicted at time of installation.The hot water circuit shall be arranged as a ringmain throughout the yacht. The ring main shall be fitted with a permanently running (220V/1/50-60Hz)) circulating pump located in close proximity to the hot water cylinders. Reverse osmosis desalination system – 1 x IdromarMC3J-180 Capacity 4320 litres/day. Rating based on average seawater salinity of 35000 parts per million and temperature range min. 33oF (0.5oC) to max. 122oF (50oC). GREY WATER SYSTEM A waste water (grey water) gravity drained system shall be fitted to all showers, baths, wash-basins and galley services on upper decks and, will drain into a 1250 litre grey water holding tank.All lower deck shower rooms, galley and laundryservices shall drain to 240V Tecma wastewater pumping units before being transferred automatically into the same grey water holding tank as specified above.All discharges (where possible) are to be fitted with‘Combi-Siphon’ air admittance water traps. For discharge of grey water directly into the sea, 1 xdischarge/macerator pump rated at 220 / 380V AC capable of discharging circa. 140 l / min is provided. This pump can be operated from the touch screens (Marine Personal Assistant) located at the bridge and main switchboard location. It can beoperated manually or set to discharge automatically upon reaching a certain set volume.For redundancy, both grey and black tank dischargepumps can be selected to draw from either grey or black tanks in the unlikely event of a pump failure.
