ocla heating system
1.2 OPERATION OVERVIEW
The OCLE/OCLA heating system is intended to maintain both optimal engine and oil temperature as well as prevent
condensation while the engine is shut down. The heating system may be activated locally or by optional remote control
( see
SECOIO 2.6.2
). The OCLE/OCLA heating system must be deactivated upon engine start-up.
During heating system operation, a centrifugal pump takes coolant from the drain area low on the engine water jacket
and forces it through the heating tank and into the coolant return line. Simultaneously, a positive displacement pump
takes oil from the sump and forces it through the heating tank to the oil return line. The coolant pump and oil pump will
continuously circulate fluid throughout the engine. To maintain consistent fluid temperature, the heating elements will
cycle on and off at the user-selected temperature control point.
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
temperature.
