Ensure the water is flowing freely from overboard discharge while the
pump is running.
The speed scoop intake must face forward and not be shared with any
other pump.
The speed scoop and the shut off valve must be tight and properly
sealed.
A seawater strainer (3) is mandatory between the shut off valve
(seacock) (1) and the pump (4) to protect the pump from any foreign
matter.
Ensure access to the filter of the strainer (3).
The seawater system should be installed
– with an upward incline from the speed scoop and seacock (1),
– through the strainer (3),
– to the inlet of the pump (4) and
– then up to the inlet of the air conditioning unit's condenser coil (5).
The discharge from the air conditioning unit (5) should run to the sea-
water outlet thru-hull fitting (6) which should be located where it can
be visually checked for water flow and as close as practicable to the
waterline to reduce noise.
Ensure the hose runs uphill from speed scoop to strainer (3), pump (4)
and air conditioning unit (5).
Avoid loops, high spots or the use of 90° elbows with seawater hose.
The air conditioning unit (5) should be installed as low as possible, but
never in the bilge or engine room areas (such as under a V-berth,
dinette seat or bottom of a locker).
Ensure proper spacing around unit.
Ensure that the selected location is sealed from direct access to bilge
and/or engine room vapors.
Mount the unit (5) on a firm, level, horizontal surface.
Double clamp all hose connections with stainless steel clamps,
reversing the clamps.
Secure all threaded connections with threaded-sealing tape. Wrap it
only 2 to 3 times around it.
Tighten one and a half turns beyond hand tight.
