These limits are designed to provide reasonable protection against harmful interference in a normal installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. [. . . ] Then remove the two straight through pipes and fit the two fuel flow sensors (see section 7-5). Install the cables to link the parts of the system together and to the Navman display instrument (see section 7-7). Warnings Correct installation is critical to the performance of the unit. Before starting installation, it is vital to read this manual and the documentation that comes with the other parts. Ensure that any holes that you cut will not weaken the boat's structure. One important thing to stress is the need for cleanliness in the installation process. Diesel engines, and the Navman sensors are built to fine tolerances - do not allow any dust, dirt, water or particles to enter the fuel system. 8 Setup the Navman instrument to use the fuel flow sensors and tachometer, as described in the instrument's installation and operation manual. Take the boat on a test run and check that the sensors are performing correctly. 2 3 4 6 7 If you are unsure where a part should be installed, mount and wire the part temporarily, without cutting holes in the boat. After the sea trials have been completed, install and wire the part permanently. 7-1 Twin engine installations If the boat has twin engines then a second diesel flow sensor kit can be fitted and connected to the same Navman instrument. To install the kits, fit a kit to each engine, following the instructions above for each engine and tank. At the display unit, connect the sensor cables from the two kits in parallel (see section 7-7-2). The sensors need to be identified as port and starboard in the display unit. You may find more instructions included in the display head manual. 22 NAVMAN Diesel fuel flow sensor kit Installation and Operation Manual 7-2 Notes on pipes, fittings and installation This section discusses fuel pipes terminology and the fittings and tape used to join the pipes. 7-2-1 Pipe Diesel fuel lines are often solid copper pipe. Copper pipes are rated by their diameter: Usually fuel lines will be called by their outside diameter (OD) - this is also typical of refrigeration pipe fittings. However, domestic copper water pipe is commonly measured by its inside diameter (ID). So ½ inch refrigeration pipe is a different size from ½ inch water pipe - make sure you know what size your boat fuel piping is before you purchase fittings to install the sensors. Push the flare nut along the pipe before flaring the pipe!!Inspect the inside face of the flared pipe - it must be smooth and scratch-free. If it is not, cut it off and try again. 7-2-3 Flexible Hoses. Flexible hoses can make installation a lot easier, but modern recommendations are that only one short length of flexible hose should be used - on the final link from the pipework fixed to the boat to the engine, to allow for flexing and vibration. In many countries a boat licensed to carry paying passengers has stringent codes of installation practice to comply with - frequently these require fixed, rigid fuel piping until the last section. If your boat has to meet such inspections, then check carefully before attempting to use flexible hoses. At the very least you may have to use metal braided flexible hose to meet fire regulations.
