Ensure that all operator control box selector switches have been placed in the appropriate operational
positions as described in the previous section entitled "Initial Operator Control Box Settings".
Once the power switch is placed in the ON position, be sure to wait the prescribed time
as indicated in Table 1. Do not turn the power switch on and off until sufficient time has
elapsed. Heat will not be supplied until after the initial startup time has passed and
turning the power switch on and off will cause the LCFH to cycle and restart the startup
Hearing protection should be worn when heater is operating with any of the
access panels open or closed. Failure to wear ear protection could result in
hearing loss or damage.
If the outside temperature is 40 degrees F or lower, connect the slave connector on the
side of the heater to a 24VDC power source such as from a humvee or cargo truck. At
these temperatures, the internal batteries in the LCFH may require supplemental power
to permit heater startup. The slave connector is not to be connected to other equipment.
When operating at a 10 degree or greater angle, the oil pressure fault code may come on

Ensure that the power switch on control panel is in the OFF position. Open engine
access door and ensure that the main battery shutdown switch (1) is in the ON position
before operating heater. Be sure to close the engine access panel before starting.
Perform a walkaround of the heater before starting to ensure that the heater is completely
ready for startup.
To start the heater, place the power switch (2) on the operator control box to the ON position. The heater
will perform a series of self tests that will be summarized on the LED display on the operator control box.
If any faults are detected during the startup sequence, the system startup will be aborted and the fault
code shown on the operator control box display. If the startup system is aborted and a fault code
