•
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 seawater
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.
!
WARNING!
•
Do not tighten the threaded connections too firmly. Otherwise cracks may
form within hours or days.
•
Before you start up the boat, check for any leaks. If you are unsure of how to
proceed, contact a qualified ship's mechanic. Otherwise there is a danger
of the boat sinking. This can result in injury or death.
