Seawater Temp 10º CIn addition to the accommodation spaces, the mainswitchboard compartment will also have sufficient air conditioning.Modular chilled water units will serve the systemwith a capacity capable of serving all lower, main, and upper deck accommodation. Capacities of the chilled water system will depend upon the yachts final destination and any options required. The condensate produced from the air handlers will be drained directly into the grey water tank.Each area / cabin shall have room mounted variablespeed air-handling units with individual cabin controls and full display in each area. All air-handling units will be positioned such that serviceability and filter removal are easily achieved. All ducting together with return and supply air grills will be sized inaccordance with Marine Air recommendations. FIRE HYDRANT SYSTEM 2 A.C. pumps will supply a minimum of 2 firehydrants positioned to ensure coverage of all areas of the vessel. Fire fighting equipment (water) will be provided at fire hydrant points (sited in fire lockers) and will have fire hoses and nozzles with instantaneous connections and quick release valves.Primary fire pump - located in a dedicated pumproom aft of the machinery space will draw seawater from the main sea chest in the engine room. The secondary fire pump - located in a locker on themain weather deck accessible to all crew will draw seawater from an independent seawater inlet located outside of the engine room. BILGE SYSTEM A central bilge discharge system driven by 2 A.C. pumps are located in a dedicated pump room (built as a watertight compartment) aft of the machinery space. This room can be accessed via the machinery space, garage or via a deck hatch. These pumps will draw via a bilge manifold also located in the pump room and will discharge overboard.The machinery space is fitted with three bilgesuctions. One connected to the engine driven pump. One connected to the bilge manifold and one direct

The ring main shall be fitted with a permanently running (A.C.) circulating pump located in close proximity to the hot water cylinders. The main run shall be in circa 25mm diameter. I.D. pipe with standard bore lines to all accommodation, galley supply lines and external faucets.Shore power water connection with pressureregulator.Reverse osmosis desalination system – 1 x IdromarMC3S with extra Membrane. Capacity 6700 litres/day. Rating based on average seawater salinity 35000 ppm and temperature range min. 33oF / .5oC 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 1350 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. The holding tank is an epoxy coated integral GRPtank. The tank will be fitted with permanently open vent lines to the mast fitted with a carbon filter. The tank has access for inspection.For discharge of grey water directly into the sea, 1 xdischarge/macerator pump rated at 220 / 380V A.C. capable of discharging circa. 160 l / min is provided. This pump may be operated manually or set to discharge automatically upon reaching a certain set volume.For redundancy, both grey and black tank dischargepumps can be valved to draw from either grey or black tanks in the unlikely event of a pump failure.Tank Monitoring – Ultrasonic level sensing of thetank level will be full range with multiple alarms AIR CONDITIONING SYSTEM All accommodation spaces including the wheelhouse and galley to be fully air-conditioned with a chilled water circulating system with reverse cycle heating to give the following states:
