Operation

If the unit is not operating and the temperature is below
60 °F (16 °C) ambient, shore power operates a 500 watt
resistive heater inside the fuel conditioning enclosure, a
6.0 kW integrated coolant pump/heater activates, and a
submersed resistive oil pan heater activates. The devices
activate independently of one another.
If the unit is operating and the temperature is below 60 °F
(16 °C) ambient, generator power operates a blower to
move air across the exterior of the exhaust manifold into
the fuel conditioning enclosure.
NOTE: Block heater and oil pan heaters are not active
while operating.

Figure 4-3. Variable Pitch Automatic Fan
While installed, the variable-pitch fan automatically varies
the pitch of the blades to maintain optimal airflow based
on coolant temperature and intake manifold temperature.
This operation will inherently minimize fan power
required and lower overall fuel consumption during cooler
ambient operating temperatures.
If a cooling system blockage occurs from reverse flow
operation (snow, ice, leaves, etc.), high coolant and/or
intake manifold temperatures will force the fan back into
forward flow operation. If the blockage is cleared the fan
will return to reverse flow operation once the coolant and
intake manifold temperatures return to normal. If the
blockage is not cleared with the change to forward flow
the unit may shutdown due to high coolant temperature
and/or intake manifold temperature.
