Operation
Ducting Guidelines
• Place ducting in desired configuration before oper-
ating the unit.
• Tightly secure ducting ends to the unit and air craft.
• Avoid sharp bends or 90° turns in the ducting.
• Use only the necessary length of ducting required;
do not exceed maximum length.
• Verify that ducting is not in a high traffic area, and
will not impede workers or other machinery. Care
should be taken to prohibit the need to step or
climb over ducting.
• DO NOT place ducting over combustible materials.
• DO NOT place ducting over surfaces that may
damage it or reduce performance, such as water,
sharp rocks or glass, electrical wiring, piping, etc.
• DO NOT place or drape anything over ducting,
such as covers, insulation, blankets or cloth, elec-
trical wires, etc.
Engine and Heater Startup
General Overview
Heater and fan behavior are driven by several user-
defined benchmarks. The fan starts when the control box
breaker is on and the green pushbutton is pressed. The
high, medium, or low thermostat turns on based on the
setting of the control box dial.
Operational Procedure
NOTE: Verify the emergency stop is disengaged before
starting.
1. Raise tow bar to engage parking brake.
2. Rotate battery disconnect to ON.
3. Turn engine starter key to position 1 .
The engine glow plug system engages. The glow
plug light will blink.
4. Once the glow plug light becomes steady, wait
approximately five seconds while fuel pump builds
pressure, then turn and hold engine starter key to
position
2 until engine cranks and starts.
NOTE: Do not hold the engine starter key in the start
position for more than 15 seconds. Doing so will overheat
the starter motor. Wait 30 seconds for the starter motor to
cool before making a second attempt to start if the engine
fails to start.
5. Attach air ducting to aircraft, avoiding sharp bends
and twists in ducts.
IMPORTANT NOTE: A twisted or bent air duct will
cause loss of air pressure and temperature.
6. Turn main circuit breaker switch to ON.
7. Press green START button to engage burner and
fan motor.
8. Set thermostat selection switch to desired tem-
perature.
NOTE: The blue light on top of the unit will flash to indi-
cate low fuel level. The amber light indicates the unit has
reached operating temperature.
NOTE: Do not use starting aids, such as gasoline. Doing
so will damage the engine.
WARNING
Burn hazard. Do not remove ducting until all air
pressure has been emptied from hose duct.
Failure to do so could result in severe injury.

WARNING
Hot Surfaces. When operating machine, do not
touch hot surfaces. Keep machine away from
combustibles during use. Hot surfaces could
result in severe burns or fire.
WARNING
Crushing hazard. Verify parking brake is properly
secured and unit is on level ground. An unsecured
unit could suddenly roll or move, and could result in
death, serious injury, or equipment damage. (000352)
CAUTION
(000291)
Equipment damage. Do not attempt to start or operate
a unit in need of repair or scheduled maintenance.
Doing so could result in serious injury, death, or
equipment failure or damage.
WARNING
CAUTION
(000229)
Equipment or property damage. Do not block air
intake or restrict proper air flow. Doing so could
result in unsafe operation or damage to unit.
