MABRU POWER SYSTEMS SC Series Installation Manual page 10

The following is a summary of the seawater system installation:
Install the seawater scoop thru-hull inlet as close to the keel and as far below the water line as possible, facing
forward. Bed the scoop with a marine sealant designed for underwater use.
Install a bronze, full flow seacock on the seawater scoop thru-hull inlet.
Install a seawater strainer below the level of the pump with access to the filter.
Mount the pump above or same level of the strainer and at least one foot below the waterline.
Connect the seacock and strainer with an uphill run of reinforced marine-grade hose.
Connect the discharge from the pump uphill to the bottom inlet of the ale unit's condenser coil with 5/8"
(15.9mm) reinforced marine-grade hose. Connect the discharge from the condenser coil to the overboard
discharge thru-hull fitting with 5/8" (15.9mm) reinforced marine grade hose.
Avoid loops, high spots, or the use of 90° elbows with seawater hose (each 90° elbow is equivalent to 2.5'
(0.762M) of hose and a 90° elbow on the pump outlet is equivalent to 20' (61M) of hose.
Double clamp all hose connections with two stainless steel clamps, reversing the clamps.
Use Marine sealant on all threaded connections.
Connect all metallic parts in contact with seawater to the vessel's bonding system, including the speed scoop
inlet, strainer, pump and the air conditioner, to reduce the possibility of any electrolysis problems.
