HEATING SYSTEM COMPONENTS NOTE: Component illustrations are for reference only and are not to scale. See part drawings for dimensions and specifications. Figure 1. Typical CMM/CLM system components. Model style and configuration may vary. See part drawings for dimensions and specifications. -
Page 8: Operation Overview
A coolant check valve (included with the CMM/CLM unit and installed at the coolant outlet) prevents backflow while the engine is operating. When the engine is shut down, the heating system should be activated locally or remotely to resume maintaining the engine’s optimal starting temperature. -
Page 9: Installation
Pump seal damage: Do not reduce the coolant supply line to an inner diameter smaller than the pump inlet; pump seal damage will occur. Isolation valves: Hotstart recommends installing full-flow ball valves to isolate the heating system in order to perform service on the system or engine without draining coolant. -
