6.Remove excess ducting and use the same connection method at the s/a grille.
All ducting should:
Be appropriately sized for each application.
Run as smoothly and taut as possible.
Have as few bends or loops as possible.
Be securely fastened to prevent sagging during boat operation.
Have all excess ducting lengths trimmed off.
Not be flattened or kinked.
Insulated when located in high heat load areas (hull side, mechanical compartments, etc.).
SEA WATER PUMP AND PLUMBING
Sea water temperature will directly affect the a/c unit’s efficiency. This a/c unit can effectively cool your boat in water
temperatures up to 908F and heat (if reverse cycle option is installed) in water as low as 40 8F. Several guidelines should be
followed during the installation of the sea water system. Since the circulation pump is centrifugal and not self-priming, it must be
mounted so that it is always at least one foot below the water line regardless of which tack the vessel is on. The pump may be
mounted horizontally or vertically, however the discharge must always be above the inlet. The pump head should be rotated
toward the direction of water flow. Install the sea water speed scoop intake as far below the water line and as close to
the keel as possible in any application, but especially on a sail boat, to keep the intake in the water so that air does
not get into the system when the boat heels over. The speed scoop intake must face forward and not be shared with any
other pump. A sea cock (shut off valve) must be installed directly on the speed scoop outlet. A sea water strainer is mandatory
between the sea cock and pump. Failure to install a sea water strainer will void the pump warranty. The sea water
system should be installed with an upward incline from the speed scoop & sea cock, through the strainer, to the inlet of the
pump and then up to the inlet of the a/c unit’s condenser coil. The discharge from the a/c unit should then run to the sea water
outlet through hull fitting which should be located where it can be visually checked for water flow, and as close as practicable to
the waterline to reduce noise. Use only reinforced marine grade hose. All hose connections shall use double/reversed stainless
steel hose clamps.
