from any foreign matter. Failure to install a seawater
strainer will void the pump and unit warranty.
The seawater system should be installed with an
upward incline from the seawater scoop and seacock,
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 seawater outlet thru-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. All hose connections shall be secured
by means of two double/reversed stainless steel hose
clamps. Use Teflon tape on all threaded connections.
