Installation
8.10.4 Installation of the Seawater System
➤ Install the seawater speed scoop intake as far below the water line and as
close to the keel as possible and with intake facing forward.
This keeps the intake in the water when the boat heels over so that air does
not get into the system.
➤ Bed the scoop with a marine sealant designed for underwater use.
➤ Apply the bedding compound liberally to both sides and throughout the
hole.
➤ Install the bronze, full flow seacock on the speed scoop thru-hull inlet.
➤ Install the seawater strainer below the level of the pump with access to filter.
➤ Connect the seacock and strainer with an uphill run using the 5/8" (16 mm)
reinforced marine grade hose.
➤ Mount the seawater pump securely above the strainer, at least 300 mm
below the water line.
➤ Mount the air conditioning unit by securing the base pan onto a flat, horizon-
tal surface with the mounting clip brackets and the 4 screws.
The base pan also serves as a condensate pan.
➤ Connect the discharge from the pump uphill to the bottom inlet of the air
conditioning unit's condenser coil with 5/8 (16 mm) reinforced marine grade
hose.
➤ Install the overboard discharge thru-hull fitting.
➤ Connect the discharge from the condenser coil to the overboard discharge
thru-hull fitting with 5/8" (16 mm) reinforced marine grade hose.
➤ Connect all metallic parts in contact with seawater to the vessel's bonding
system including
– the speed scoop inlet,
– pump (the harness ground wire),
– the air conditioner.
