Installation Diagram(1) Ether cylinder assembly.(2) Clamp assembly. Position clamp assembly 178 mm (7.0 in) vertically above ether valve assembly mounting holes.(3) Ether valve assembly. With ether cylinder assembly (1) installed, the valve assembly provides 2.25 cc of ether through the steel tube to atomizer (8) in the air inlet manifold system each time starting aid switch (5) is pressed for three seconds, then released.Locate as close to the engine air inlet manifold as possible (do not mount on engine).Do not mount in a location that subjects ether valve assembly (3) and ether cylinder assembly (1) to temperatures greater than 93.3°C (200°F).Install ether valve assembly (3) so ether cylinder assembly (1) can be installed in a vertical position as shown.(4) Temperature switch. The temperature switch will not allow starting fluid to reach the atomizer if the engine temperature is above 38°C (100°F). Remove the 3/8 inch pipe plug from the cylinder head and install temperature switch in location shown in the engine series detail.(5) Starting aid switch. Install switch close to operator's starting station. Switch requires clearance hole for 5/8inch diameter thread, and 38 mm (1.50 in) depth behind control panel or mounting bracket.(6) Ether valve connector.(7) Steel tube. Assemble 3.18 mm (.125 in) OD steel tubing between valve assembly and atomizer assembly. Use the flexible coupling tube assembly as a flexible connection between the two lines. The use of any additional length of tubing is not recommended. No electric wires are to be clamped to the ether line.(8) Atomizer assembly. Remove 1/4 inch pipe plug from air inlet system and install atomizer assembly. Before atomizer assembly is tightened, turn identification mark to direction shown in engine series detail for correct alignment of ether spray.
