- Page 3 IDENTIFYING YOUR SYSTEM IOM216272-000 The HOTSTART heating system is designed to heat fluids for use in marine propulsion, diesel-powered generator sets, locomotives, gas compression or any large-engine applications. Each heating system has an identification plate which includes the part number and serial number.
- Page 4 Overcurrent limiting: The power supply must be protected by a suitable overcurrent limiting device. • Power disconnection: A means to disconnect the heater from the power supply is required. HOTSTART recommends that a power switch or circuit breaker be located near the heating system for safety and ease of use.

OVERVIEW WARNING System location classification: Before installing the OCLE or OCLA heating system, ensure all system components are suitable for the intended installation location by referring to the location classification labeling attached to the individual system components. HEATING SYSTEM COMPONENTS OOE: Component illustrations are for reference only and are not to scale. -
Page 8: Operation Overview
A coolant check valve (included with the OCLE/OCLA unit and installed at the coolant outlet) and an oil check valve (user- supplied and installed near the oil suction port) prevent 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... -
Page 9: Installation
If the pump is installed above the minimum oil level, a check valve must be installed. 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 the fluid. -
