Initial Startup/Testing Procedures
NOTE
If the heater fails to start the first time it will automatically attempt a
second start. If unsuccessful the heater will shut down completely.
NOTE
On initial startup the heater may require several start attempts to self
prime the fuel system.
a.
Turn on the engine coolant heater manually by pressing the "heater on"
pushbutton
on the seven day timer. The fuel line will be full and bled when the fuel delivery is
uniform and bubble-free (after approximately 60 seconds).
b.
Ensure proper operation of the coolant heater as described in the Theory of Operation
Section of this Appendix.
NOTE
After running the diesel engine to bleed the coolant system, the coolant
may still be warm during initial startup/testing. When the coolant heater is
first turned on and only the water pump and combustion air blower are
running, the warm coolant will cause warm air to be exhausted even
though ignition has not yet occurred. When the coolant heater has ignited
the exhaust can be clearly heard coming from the exhaust pipe along with
hot exhaust air.
c.
Replace cover (1, Figure J-13) on engine coolant heater boxed enclosure (2) and secure
with two bolts (3).
