Gray Water Drain System
•
Gray water (water from sinks and showers) above the waterline is gravity drained overboard, while gray water
below the waterline is drained into a holding tank. The holding tank is located in the aft section of the utility room.
•
When the holding tank reaches a predetermined level, the tank’s float switch automatically activates the sump
pump to empty the tank’s gray water overboard. The shower sump pump and holding tank are located inboard of
the water heater inside the utility room.
Transom Shower
The transom shower is located inside the inboard transom stowage tub.
Seawater Systems
Seawater Strainers
Seawater strainers are used in water pickup systems to filter incoming seawater. The typical layout is one strainer for
each of the following: Engine, optional generator and optional air conditioning system. Seawater strainers are
located near seawater intake valves (seacocks) and should be checked every time you use your yacht for leaks and/or
debris. If debris is found, clean the seawater strainer as follows:
WARNI NG!
SCALDING HAZARD! Water heated by the water heater can reach temperatures high
enough to scald the skin.
!
•
DO NOT energize the AC water heater electrical circuit until the heater is completely filled
with water. Even momentary operation in a dry tank will damage the heating elements.
Warranty replacements will not be made on elements or tank damaged in this manner. The
tank is full if water flows from the tap when the hot water is turned on in the galley.
•
The water heater should be drained and the power turned off when the possibility of freez-
ing exists.

LOCATION
•
FLOODING HAZARD! The seacock that sends seawater to the strainer must be closed
before disassembling the seawater strainer to prevent the yacht from taking on water
through the seawater strainer assembly. Keep the seacock closed until the seawater strainer
is completely reassembled.
•
SYSTEM DAMAGE HAZARD! After reassembling the seawater strainer, verify that the
seacock valve is open before component/system operation.
