OPERATION OVERVIEW

The OXM/OGM heating system is intended to maintain an engine's optimal oil temperature while the engine is shut
down. The heating system may be activated locally or by optional remote control (see SECOIO
heating system should be deactivated upon engine start-up.
During heating system operation, a rotary gear pump takes oil from the sump and forces it through the heating tank to
the oil return line. The oil pump will continuously circulate fluid. To maintain consistent fluid temperature, the heating
elements will cycle on and off at the user-selected temperature control point.
A return line check (non-return) valve (included with the OXM/OGM unit and installed at the outlet) and a supply line
check (non-return) valve (user-supplied, 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
fluid's optimal temperature.
