Primex™ Installation

1. All components are for wet exhaust systemsONLY.
2. Ideally, components should be installed a minimum of two feet downstream from the point of cooling water injection.
3. Continuous operating temperature should be less than 200° F for optimum system life.
4. Components should be supported for entire length of system.
5. All components must be isolated from vibration with approved marine exhaust hose and double hose clamped at each connection.
6. Lubricate hoses with water or liquid detergent only.
7. Silencers and check valves should be installed as close to level as possible. A slight system slope aft is preferred.
8. Exhaust outlets should be above the loaded water line.
9. All procedures should conform to ABYC standards and recommended practices for small craft.

Naqualift™ Installation

1. All components are for wet exhaust systemsONLY.
2. Ideally, components should be installed a minimum of two feet downstream from the point of cooling water injection.
3. Continuous operating temperature should be less than 200° F for optimum system life.
4. Components should be fully supported.
5. Naqualifts should be installed as close to the centerline of vessel as possible.
6. Have top of Naqualift at least 12"e; below the exhaust manifold.
7. Isolate all components from vibration with approved marine exhaust hoses and clamps. Lubricate hoses with water or liquid detergent only.
8. Below water-line installations require a "e;siphon-break"e; to prevent water flow after shut down.
9. All procedures should conform to ABYC standards and recommended practices for small craft.
