OVERVIEW WARNING System location classification: Before installing the OLA 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. See part drawings for dimensions and specifications. -
Page 8: Operation Overview
OPERATION OVERVIEW The OLA heating system is intended to maintain optimal oil temperature while the engine or compressor is shut down. The heating system may be activated locally or by optional remote control (see SECOIO 2.5.2). The OLA heating system must be deactivated upon engine start-up. -
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 oil. -
